Re: [TANKS] 3D printers

[Thomas Lum]

 I can recommend the Printrbot simple. We have them at school after I bought a 
personal one and tested it for 6 months and they print very well right out of 
the box. Also, if something goes wrong, the most expensive thing on them is the 
control board and that's less than $100. 
That would be in the same price range as the davinci. I know nothing about the 
davinci however.

Some were intended as throw-away parts, others were simply mistakes. 
None of these parts will ever see the battlefield.

Re: [TANKS] My T34/85

[Thomas Lum]

Very easy to build a reliable computer. They have a lot less parts than even 
the most basic lego set and snap together just as easy.  I built a full size 
tower and the only thing that gave (gives) me trouble is the d-link wireless 
card.  Almost every pc magazine publishes either online or paper version of a 
gamer pc under $1000 build.  Start there and don't skimp on the power supply.  
If you have a CompUSA near you, just walk in and tell them your budget.  Their 
prices are comparable to NewEgg and if something is wrong, you don't have to 
ship it back.

Thanks guys. Return idlers was the word I was looking for. I think I'll stick to the tank. But since I live way out where I do, don't expect me coming around for any battles. Besides, I'm not sure my very first tank is going to turn out too well--if I get to battle with any of you I want it to be with a second tank already. :) I saw the (what's his name?) two latest tanks made by the same guy that were really cool. That's what I want to build like. 


Hey, have any of you built your own computer before? Just an idea in my head, 
but if you have I am currently putting together a parts list to go from 
someday. And buying computer parts right is probably the hardest part.

Re: [TANKS] track talk

[Thomas Lum]

We have a printer at my school and would not mind printing some parts for 
people just to learn how it works. I'll get in touch with the tech guys and see what I 
need to do it. I did ask about cost and they said something crazy like $5 per cubic 
centimeter!

Here are the disadvantages of 3D printing compared to molding parts:

1) ABS plastic is not as durable as the polyurethane we use when molding
parts.

2) When molding, there's a 5 minute cycle time for a batch of parts (we
do 8 parts per batch), each part will probably take at least 15
minutes on a 3d printer.

3) The plastic used by the printer is more expensive per pound than that
used for molding.

4) If necessary, you can easily add a strip of fiberglass to molded
parts to increase strength. That is not possible with printing.

Basically, when it comes to mass-producing parts, molding is the
cheapest, fastest and most flexible approach.

As Joe said, the real winning combination is to use a 3D printer to make
the master part, then make molds from them. We've done that for a
couple of parts (drive cog, experimental pumps) and it works great. If
you do get a Thing-O-Matic, you should expect a never-ending stream of
3D requests from Maryland for master part production (in exchange for
mold making if you want).

 Hi all, This discussion (Is the Ontos a tank) was taken up over two
 years ago. The conclusion then was, it is a tank.
   For reference, the marines used these in Vietnam, most commonly for
 anti-personel work with honeycomb shot (105mm shotgun shell). For anti-
 tank work they used a shoot, scoot and hide routine. Reloading while
 out of sight.

 The reason for my post was to feel out if there was any interest in my
 tank, before I start to cannibalize it for parts. But there was not
 much interest, mainly due to budgetary constraints. That's OK, because
 the value of the tank in parts is at least what I paid for it. I felt
 it would be better to put any additional investment of time and money
 into a new, better design, using the old tank's parts. What's left
 over would be the chassis/hull and drive train of the tank, which
 hopefully I could sell. I would think the TTS tracks are especially
 valuable, because that is such a labor intensive component. The metal
 hull should also have value, because most people don't have the tools
 for cutting and welding a hull.

Re: [TANKS] high current electrical components

For switches, this might be your best bet.  Also, if you live near a boat 
supply store, a lot of these items can be found there.

I also picked up my fuses there.  The boating stores all deal in DC power.  
Other may be better at the conversion but AC fuses at 120 volts I don't think 
are 10 times more powerful at 12 volts.

Re: [TANKS] Reasons why track chain attachment throws off its sprocket

[Thomas Lum]

Attachment chain actually has a lot of lateral play for it's size. If your 
bogies aren't keeping it tracking correctly especially on turns at high speed, 
there is a good chance of a derailment. Also, although those sprockets are big, 
there isn't as much engagement as you would expect, the teeth aren't that deep 
and if the chain doesn't come in square to the sprocket it causes a lot of 
trouble.

https://www.surpluscenter.com/item.asp?item=1-1163-160-4catname=powerTrans
i think they goofed on the weight - don't think it's 290 pounds

https://www.surpluscenter.com/item.asp?item=1-2890-10B-3catname=powerTrans

https://www.surpluscenter.com/item.asp?item=1-1163-40-4catname=powerTrans
now this one has 40 pitch listed, so i know that's the same as  
what's going on the Tiger but still lacks info such as width


https://www.surpluscenter.com/item.asp?item=1-2890-12B-3catname=powerTrans
what's 12b?

https://www.surpluscenter.com/item.asp?item=1-2890-16B-3catname=powerTrans
12b?

https://www.surpluscenter.com/item.asp?item=1-2890-20B-3catname=powerTrans
20b (and 80lbs, a bit too much weight to be adding to a tank just  
for one of the tracks)


https://www.surpluscenter.com/item.asp?item=1-2890-28B-3catname=powerTrans
wait, 207 pounds? just how big is this at 10'

https://www.surpluscenter.com/item.asp?item=1-2890-32B-3catname=powerTrans
and this one is over 200lbs for a 10' length as well - i don't think  
they tiger will weight that much going into battle (well maybe)

Hey all, long time no post.
Just noticed this D drive and I just happen to have started on a triple diff
transmission using planetary gears for my big tank
There are so many similarities with the D drive and a modern triple diff
tank transmission.
What this guy has done is modify the steering diff to become a drive diff.
The smaller motor to change the ratio is the motor that would steer the tank
and give it reverse. It works exactly the same.

When I saw this I understood it because I have been toying for a few months
and have already started buying the gears etc.

The difference is in the D drive the main motor is permanently running at
optimum speed and the smaller motor changes the gear ratio to the point of
also giving it reverse.
In a tank the main motor has a variable speed and the steering has also so
when combined you can mix between the two to get speed and steering.

Still early days for pics but if there is any interest in this project I
will put some up.

I have built many vehicles and its become clear that a 3 diff setup is what
I have been looking for, its a beautiful thing but not required for paint
ball at all, having said that I do expect to have a lot more control at high
speeds compared to a skid steer tank, will be interesting.

 Only, instead of two sets of pulleys, you have two cones and a mechanism to
 keep the belt taut on those cones.  Move the belt one way and you get more
 torque, less speed. Move it the other, you get more speed, less torque.

 Having

 it like the gears of a manual gearbox, with the variability of a CVT.

 Nice concept.  I'm glad they addressed my concern of having to power
 the second shaft.  I was on board until he said he estimated it to be
 an _order of magnitude_ more efficient than the current CVT
 transmissions (not geared transmissions, but CVTs even!).  We'll see
 where this ends up when you figure in powering that second shaft.  I'm
 guessing (with no facts or numbers whatsoever) that it will be on par
 with losses associated with a torque converter (which may be OK
 because at the end of the day this thing is still a high-torque CVT).

Re: [TANKS] spektrum radios

[Thomas Lum]

Sounds like you need a lot of questions answered about rc gear.  The  
receiver will work off of usually the speed controller in your  
vehicle. If you need to, you can just use regular batteries since the  
rx (receiver) doesn't draw a lot of power.  Most servos will work  
directly by plugging them into the rx, digitals included.  A servo  
programmer is usually used for precise control to set the end points  
and throw and speed of throw for each servo, like for rc jets or some  
high detail scale models, usually not tanks.


Now a question for you, do you NEED digital servos?  Usually they are  
needed for airplanes or helis that need constant adjustment and  
position sensing.  Might find an analog servo of similar specs for 1/3  
if the cost.


I'm no expert but that's what I've pick up for running rc for a while.

Re: [TANKS] sherman m4a3

135 watts would need a lot of gearing to run a tank.  Continents would  
move faster.  It's been said a few times before but the m01 motor is  
an unstoppable motor and it comes with almost perfect gearing.  It  
should be on anyone's short list for tank propulsion.

RE: [TANKS] spektrum radios

Honestly, I didn't know spektrum made servos.  Servos come from a lot of 
manufacturers, Hitec, Futaba, Hobbico, Tower Hobbies, and more that I am 
forgetting.  I'm not saying a Spektrum servo isn't what you want but you may 
want to check out tower hobbies website and get a feel for all the options out 
there.  I think they also have a few guides as to how all the components link 
and work together, it can be confusing when starting out but it's fairly 
straight forward once you get a handle on it.

 I am about to make an M113 out of steel and by my calcs with 2mm steel it

 have a turret. If you went for a 1/6 Abrams or similar large vehicle then I 
 guess you could hit 100kg easily.

 They seem to be about 50-100kg (No, I'm not converting it for you), 
 depending on what they are made out of. A mild steel tank would weigh 
 upwards of 100kg I would think. Has anyone actually made a steel tank?

They are also good if you want a flat bottom (with just a little indent in the

 I concur, a power miter saw is a good way to make wheels (and somewhat
 safer).  The road wheels on T047 (http://rctankcombat.com/tanks/T047/)
 were made this way.  The Cromwell's turret rotate drive and elevate
 wheels were also cut on the miter-saw (http://rctankcombat.com/tanks/
 T040/13Cromwell038-large.jpg,
 http://rctankcombat.com/tanks/T040/13Cromwell036-large.jpg).
 
 Hint: for really precise wheels bore the center bearing hole first and
 use the actual bearings and shafting you will use in the tank to build
 your rotate jig.  Another hint: for really precise holes in plywood
 get yourself a nice Forstner bit set.  Don't waste your time with
 twist or spade bits.

Re: [TANKS] some information needed ....

[Thomas Lum]

 

here's my list of topics i would like to know more about :

-- motors ? i saw everybody here's using big motors with a lot of
power (120W and more)
  but your models are 1/6, so thats a LOT bigger. how could i like
calculate what torque would i need, what
  rpm, for my tank. i currently have 2 stepper motors, with 50mN/m (i
think thats like 40inchlbs, not sure tho)
  but they seem a little bit to small.

First tip, it's easier for us to build on 1/6th scale because almost all the 
hard work has been done for us.  Most know what works and what doesn't.  If you 
blaze out into a different direction, you are going to have to buy and test a 
lot of things yourself.  Your motors depend of your tank weight.  Make your 
build modular so you can switch something out easily if it doesn't work.

-- drive shafts, coupling, connecting wheels.
   basicly i have no idea how to do that. i know what i would need to
do in theory, but how exactly do you connect
   another longer shaft on that small shaft of a dc motor ? (its too
small to drill thru or anything) ?

Most of the time the motor has a shaft that you connect either a pulley or 
sprocket to.  You then use belt or chain to attach that to either a second belt 
or pulley, or sometimes directly to the main axle shafts.

 how do
   i connect non-powered wheels (the middle ones) so they can turn on
the saft, 

Bearings and lock collars

and how to connect the
  powered wheels so they cant turn on the shaft ? 

Usually you use set screws, keyed shaft or you have to fabricate something to 
mate the shaft to the wheel (I think the Cromwell, Tiger or Comet has a good 
pic of this)

all little things
like this, basicly some building manuals, tutorials,
   books, anythings with pictures would come in handy.

Read every tank build on the website, that is a bible of building.  Also look 
at the tanks that are old and still going.  Cromwell, Comet, Tiger, Hetzer, 
SU-100, Bad Kitty, and a few more I am forgetting.  Anyone (almost) can build a 
website tank that never goes to a battle (me for instance), but those tanks I 
mentioned are punished and still run every battle.  They are a guide to what 
works well.  

Also anything Frank says is gospel.

Re: [TANKS] were to start

[Thomas Lum]

Start with batteries and drivetrain  The widths of those items cannot be 
altered much.  For instance if you are going to use M01 motors, you need about 
12 inside.  That will dictate your scale size.  Battery height is another 
consideration.  Be sure to include space for your terminal connectors.

[TANKS] Re: 7 TP

[Thomas Lum]

I used MDO plywood on my last tank, it's what they make outdoor store  
signs from and when painted, it's completely smooth like glass, almost  
too smooth for a tank!  I'm not sure about the exact price but it is  
probably more expensive than cabinet grade plywood, but it doesn't  
(can't) be sanded due to the finish on the wood.  Do not confuse it  
with the more available MDF though.
Tom
On Jul 15, 2009, at 9:20 AM, Steve Tyng wrote:


 If you want a smooth finish on your plywood tank, first start with
 decent plywood.  I cringe every time I see a tank being built out of
 cheap AC exterior fir plywood.  Not much you can do with cheap ply
 other than cover it with fiberglass cloth and resin.  Look for plywood
 with a nice exterior veneer of some sort of fine grained wood like
 birch, poplar, or maple.  I'd avoid oak or luan veneered plywood due
 to the open grain of these woods.  The types of plywood I am
 describing are usually marketed as cabinet grade or some other such
 nomenclature.  They are also usually interior grade but that's not an
 issue since were building tanks here and not boats and you'll seal the
 edges anyway.  I prefer finishing with two coats of TiteBond2
 waterproof glue.  The first coat fills the pores, and once lightly
 sanded and covered with a second coat, leaves a very smooth base for
 your paint.  For paint I prefer a quality flat interior latex house
 paint (it's cheap and can be mixed to any color you want).  For a
 sand-casted look Rustolium makes several varieties of textured spray
 paints that can be used to add depth to your hull.

 If you build out of decent plywood and finish as described you will
 not have to fiberglass or otherwise spend an inordinate amount of time
 working on the exterior finish of your tank.

[TANKS] Re: Small 12v ESC - recommendations?

[Thomas Lum]

My best guess is that it's a feature of the esc.  It's made for RC  
cars that are going forwards at a great amount of speed and if you hit  
backwards (by accident or one purpose), it won't immediately do that  
because more than likely it would break something in the car if it  
slammed into reverse.  You need to double pump it to confirm you do  
indeed want reverse.  You might want to check the manual to see if it  
can be disabled.

 and I am having problems with it. It's working, but say I rotate it
 forwards, then I go backwards, then I try to go forwards again
 and it won't go, if I release the stick and then try forwards again,
 it works? what gives? It's like it needs confirmation that I actually
 want to change direction, but it only does this when going from
 direction B to A, going from A to B is fine, or from B to B, or from A
 to A (I use the terms forwards and backwards above with no
 specific direction intended, the point being the problem is only
 experienced when changing directions, in one direction, if that makes
 sense). Once it is going in any direction, stopping and starting again
 in the same direction is fine.

 Does anyone have any idea why it would do this? Do you think there's
 something wrong with it, or could this behaviour be by design? The
 seller states its meant for RC cars, in which I have no experience,
 but that fact may light a bulb for someone.

 Failing a fix, can anyone recommend a small in size and capacity,
 cheap and reliable (the holy trinity!) 12v ESC for the task?

 Subject: [TANKS] High Power Servo Hack


 
  I've renamed the subject of this thread back to High Power Servo
  Hack so lets not try to hijack it again (do not change the  
 subject on
  these emails).
 
 
  Now back to the topic at hand.
 
  There's been discussion on making custom h-bridges in lieu of the
  commercial boards available.  I've found the following integrated h-
  bridge modules currently listed on eBay.
 
 
  http://cgi.ebay.com/MPM3002-Motorola-H-BRIDGE-MOSFET-POWER-MODULE_W0QQitemZ200308339465QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116
 
  http://cgi.ebay.com/1ea-ST-L6203-6203-Full-H-Bridge-Motor-DRIVER-IC_W0QQitemZ400020364797QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116
 
  These are obsolescent out-of-production h-bridge modules (include  
 all
  four driver FETS) that could be utilized (with a small amount of
  additional components) to drive external motors (up to the current
  rating of the module) and can be driven by the hacked servo.
 
  An interesting and current (in production) h-bridge device is the
  Infineon TLE5206-2 driver.  This is a basic h-bridge driver that
  includes over amperage and temp sensing built-in and only requires  
 one
  external capacitor.  It can handle a continuous 5amps which should  
 be
  plenty for a steering servo setup.  DigiKey has these at under  
 $8US in
  single quantities.
 
 
  http://www.infineon.com/dgdl/tle5206-2_20010619.pdf?folderId=db3a304412b407950112b43820d56a4afileId=db3a304412b407950112b438215b6a4b
 
  If you review the datasheets for these devices you will find all the
  info needed to utilize them in the hacked servo project under
  discussion.

[TANKS] Re: Recon video

While I can't give you a ruling, it's looks like a great little  
machine.  How do you steer it and are all the wheels powered?

 HI

I recorded short videos of my Recon running in the backyard.  The  
 video are of very
 poor quality, I apologize, but I only have my cellphone to record  
 video, so the resolution
 is small, and as I was holding the cellphone in my left hand and  
 driving the Recon with
 my right hand, it get easily out of frame.   With these 24v 300amp  
 motors the vehicule
 have more than enough power.  If only summer was coming faster.

I have one PanzerIII T050, to battle if ever some battler spawn  
 in my area, so was
 originally thinking to build a KingTiger, but turn the lower hull as  
 a 6 wheeled Recon, just
 for the fun of running it around.  Cant wait for some forest ride in  
 summer.  I use the
 same electronics than the PanzerIII, gotta use it at the price it  
 come, and it work
 to good to wait an ennemy tank.  I plan to buy a new car soon, it  
 will be choosed to
 accomodate a tank in the back to increase my battling range.

I was wondering, as I fine tune this Recon.  As its a 1/6 scale  
 hull of KingTiger, but
 on wheels, would it be possible that I battle with it if I install a  
 rotating turret with
 paintball gun on top of it?  I build this vehicule with in mind the  
 idea to replace the
 turret for anything else ( ex: robot arm ) as a multipurpose RC  
 mobile base.  Simply said,
 can we take liberty with our tank design? If not np, I can still use  
 it as Recon and supply
 vehicule.

 Nothing too bad, I need to rework the chain tensioner after I drove

 I also need to address the bump steer/front alignment issues, but
 nothing new.

 The chain popped off and I flipped it a few times...

[TANKS] Re: 3 stage transmission

[Thomas Lum]

I am always impressed w/ George's work, there's something about a  
dented metal tank that makes it twice as good.  What did you use on  
the inner hull where the torsion rods go through, did you make those  
or are they from another part of something?

 Some progress at last.
 Still a bit to do, some welding, drilling, tapping about a days

 Should say this was a PITA and would not do it again, while putting  
 this
 thing together was always thinking what if this chain broke etc so  
 had to
 build in servicing and repair considerations.

 The gear ratio is 12:1 and the motors are about 320 watts at 12  
 volts but
 will run it at 24volts also.
 When moving this vehicle uses 56 ball bearings and 12 bushes for the  
 arms so
 it should be efficient.

 Will be able to adjust tension on all the chains and be able to  
 disassemble
 the transmission hopefully fairly easy.

 When welding is finished will pull apart and paint, set the bearings  
 and
 take some photos when its in pieces.

 Even though its been a bit of a pain am looking forward to seeing  
 this move,
 hopefully should be driving within 2 weeks or earlier, apart from
 transmission only have 4 road wheels left to do.

[TANKS] Re: drum servos

[Thomas Lum]

Not to beat a dead horse but Frank is dead on with this building  
philosophy.  We all know how much time goes into these beasts and  
battles are few and far between.  If something breaks that can't be  
repaired instantly, you lose time doing what you spent scores of hours  
building and preparing for, especially if it's your first battle.   
Some of the veterans cherish punishing their tanks (they get a crazy  
look in their eye) because they know they can, they are that well  
built.  The question is, can you do the same?

Always figure the worst case scenario.  Turn the turret sideways so  
that the barrel is perpendicular to your direction of travel. Bring  
your tank up to full speed and run your barrel (just the tip) into an  
immobile object at full speed.  If you think your servo will survive  
that collision, build on.  If not, plan on a different mechanism with  
slip built into the system either with a belt or roller.

speak from experience) Lum

 Yep.  But that's all that is needed when using a low RPM geared motor
 for a rotate system.  Cheap, powerful, simple, effective and reliable
 ... hard to beat that combination.  Of course, if you want to spend  
 more
 money for a more complex and less reliable proportional speed control,
 you can add that if you want.  Simply replace the servo/switches by  
 the
 speed control (keep the servo/switches in your field box, because
 eventually you'll be putting them back in the vehicle when the speed
 controller starts acting up.)

 When it comes to servo motors, a hacked servo simply won't have enough
 torque or reliability for rotating a fully equipped turret.  Hacked
 servos are great for kiddie toys and table-top robotics, but our tanks
 are at least an order of magnitude larger than such things.  (The one
 thing you learn in the science and engineering world is to respect
 orders of magnitude.) We're talking about quite a few pounds of weight
 in the turret alone being tossed around by various dynamic forces on  
 the
 battlefield (including the inertia of 100+ pounds when you run into
 something) and the rotate motor has to handle such loads many, many
 times in a single battle, let alone over many years of battling.

 Just keep one thing in mind:  No veteran battler has ever been sorry
 because they over-engineered any of their tank systems.

[Thomas Lum]

Clodbuster axles can be built bullet-proof but expect to pay $250 per  
axle to get them that way.  They would work for a 1/6th scale vehicle

 have the motors attached directly to the wheels to eliminate the
 complex drive trains. And also to have skid steering rather than
 ackerman. Not sure skid steering would work for rock crawling, but I
 don't want to do rock crawling. (Maybe crawling over tanks?) I just
 think the design would be good for general all terrain performance. I
 have not found a good motor-wheel combination for that yet.

[TANKS] Re: can we use 4 motors?

[Thomas Lum]

 This is all my opinion of course but...

 1-Is it working like, if I place 2 motors on each side the vehicule  
 will have twice the power?

Yes


 2-If yes, can I just combine + and - cables of same side motors and  
 have the drive chain pass by
 the two motors gears ( each motor need a gear with absolutely the  
 same number of teeth of course ) to
 install the second one?

You can, some guys in the RC crawler world swear by series wiring,  
others say it doesn't matter.  I have also heard to making the front  
spin slightly faster (1 tooth difference) to help with steering and  
climbing.


 3-If yes, is the Amp. of combined two motors will double the load  
 and put a bigger hazard to my ESC?

I'm not sure but it might not double the load since each motor will be  
working less than before.  It will obviously be more than before but  
not twice as many.


 4-do I miss something?

You could add more voltage and increase your gearing if your system  
could handle it.


 Thank you, Greg.

 http://www.surpluscenter.com/item.asp?UID=2009021006243189item=5-1577-4catname=

 Could I use a speed controller and self centering joystick or is  
 there a
 better method that utilizes the potentiometer?
 I want to use it for a gun elevate.

 Do you really need an actuator capable of lifting 100+ pounds for your
 elevate mechanism?  Seems like overkill to me.

 But, to answer your questions:

 1) You don't need a speed controller, just some on-off switches, to
 create a latched elevate mechanism.  Push joystick to go in either
 direction, let go to have it stay in that position.  (This is how most
 motor-based elevate mechanisms work).

 2) You could utilize the pot using a microcontroller to turn the
 actuator into a powerful proportional elevate mechanism.  In that
 case, when you move the joystick the actuator will move to the same
 relative position.  However, given the size of the mechanism there  
 will
 probably be a perceptible delay to get from one spot to another, which
 will make it difficult to use effectively.

 Personally, I prefer to go with a simpler geared motor solution  
 using
 small, but powerful 6 RPM geared motors with a lifting arm and two  
 limit
 switches.  Smaller, cheaper ($10) and extremely robust.  Both the
 Navaronne and Tiger have been using such an approach for years  
 without a
 failure.

 BTW: Within the next month, I hope to have some prototypes built for a
 new circuit board that is specifically designed to control such
 mechanisms (elevate, rotate, fire control).  More details to follow.

Not to thorw $40 at the situation but they do make tank mixers (Frank

What you are describing is a slip ring (I think).  I think if you

They can be very expensive but a low cost alternative was suggested.   
I think there was a mention of a telephone handset cord swivel (back

 Has anyone built/used/found some kind of circular electrical contact
 solution for turrets? The idea being that to get electrical
 connectivity from the hull to the turret, and still be able to turn
 360 degrees all day long, I need to get electrical contacts through
 some kind of circular connection.

 This is rather than using wires which will get twisted by turret
 rotation. I realise that most of the time turrets are never going to
 get rotated enough to worry to much about twisted wires, but it would
 be nice not to have to worry about it at all and just be able to turn
 around and around without hinderance.

 I don't think I explained that very well, but hopefully it makes
 sense :)

 OK. So, I will soon be needing to make wheels. Now at 1/4 scale

 wheels is out of the question. I was thinking of making one wooden
 wheel plug and making several molds out of it. I can then use the
 molds to make more of the exact wheel. This is time consuming though.
 And I'm not quite sure what materials to use.

 I don't have a lathe, And I don't think I can justify to the wife why
 I need one. The tank in question is a 1/4 scale Tiger II and the
 wheels need to be 7-3/4 to 8 in diameter and I would like them to
 look realistic as well. I can compromise on the look a bit I guess.

 Does anyone have any suggestions? I was considering cutting out 36
 discs and using 8 poly pipe as the tire just like Dave Manson's
