 Your geometric chuck for the LOM is in another class!  WOW!  First
 question (suppressing many others) is how do you cut those gears?  I have a
 gear geometry program to create a printed pattern, but cutting it on the
 scroll saw seems to lack the accuracy that is desirable. They are just spur
 gears, so an indexing head on a mill ?

 This would be way overkill for the trammel, but I LOVE overkill.

 Ivandea.  If one used narrow timing belts, would that eliminate a lot
 of the gears?

Hey Brett somethings in life we just roll with and use what we've been
blessed with .
Your learning the Legacys that take some thinking. there are times I am
sure we all wish we were
smarter then we are, but we can't get hung up on envie we have to count our

Thanks for the complement. But Smart I'm not ( Bill, Tim, Mike... Are.) But I
am just persistent, and I've been reading and trying to learn this OT stuff
for years. Think of it as, like a second language. (I'm not very good at it,
but I do try. My skill level is , Not yet proficient, but I can get my point
understood. ) ;-) That's why we have this group. We each can learn and grow
form the experiences that we share.
Have a Great day.

 Hey Bill
I have about 1/3 of the work done already. I have proto typed a few different 
sets of gears.  There is still a lot of work to be done.  I think I have the 
design ready to go. (in my head.)   I need to keep it small so it will fit in 
the Legacy, some OT details still need to be worked out, Minor things like do I 
make the adjustment/off set. pin locking  or do I use some kind of fine 
adjustment, like the originals had? (by the way, I've seen two different 
Geometric chucks, both worked on the same principles, but each had different 
parts and orate nation.) The pin would be easer and smaller to make, but the 
fine adjustment ??? Is it really needed? I don't think it would be? but I'm not 
sure.
Once I get a working modal , I will post the prints and notes, so others can 
make there own.  Un-like the roping attachment, I don't see my-self making any 
more then absolutely nessasary.  (my proto types only.)   But lets not put the 
cart, before the horse, I need to get a working modal before I can go any 
further. But It Is a Pretty Neat Idea. That I've been dreaming about for a long 
time.;-)

Hello Dan

  

I've been working on a jig to do just that with the Legacy.

Its not done, YET, and may not be done until when I can find the time to work 
on it again. (Most likely this winter.) But in the OT world its call a 
Geometric chuck.

https://www.youtube.com/watch?v=je7Xa6wqo-A 

There are many books and video's on this topic.  

  

My hope is to make one for the Legacy Ornamental mill,  I have a very good 
understanding on how it works,

Mine will be mounted like a rotary table, on the rails of the Legacy. AND  have 
the router over head/top of the work piece.

  

More latter.

Have a good day.

Hello Dan.

 

a timing belt No. but perhaps a timing chain could work.

The easiest way to look at the Geometric chuck is to see a planetary modal. the 
Sun is in the center. (1st gear) the speed control is like the Legacy 
directional gear set. (spins either left or right.) The reduction gears are 
like the Duplex gear on the Legacy to control the speed of rotation. The center 
hub would be the headstock of the Legacy. It turns the part on the faceplate.  
Now there is only one other thing you need to think about to make a Geometric 
chuck. and that is the off-set of the faceplate/center, from the rotation. to 
make the arcing movement.  

The gears in the photo a friend of mine made, I did not do it. He used a gear 
machine to make those, (basically its an indexing head on a milling machine, 
but his machine was made to only make gears, so its a specialty machine.)

I plan to make my gears with a laser engraver, and to make my gears out of 
plastic.  

I plan to set my system a little different that what Frank did (he is he one 
who made the modal I posted the photo's of in my first posting/reply.) I plan 
to make the directional gears touch the planetary gear. 

If I make the directional gear have three locks for the lever which controls 
the rotation, One/right, Two/ left, and Three/ neutral, (for indexing of the 
part. and keep the speed control gears on top for easy changeover.) 

I also plan to use a 5/8" shaft for the center/ upper hub, to cut down space 
and make it so I can use My Shop Smith faceplates with this jig.

 

Like I said I've done a lot of research on this topic. Its just a matter of 
time. before I get it done.

 

I hope this helps you understand how the jig/ Geometric chuck works?

Your geometric chuck for the LOM is in another class!  WOW!  First question 
(suppressing many others) is how do you cut those gears?  I have a gear 
geometry program to create a printed pattern, but cutting it on the scroll saw 
seems to lack the accuracy that is desirable. They are just spur gears, so an 
indexing head on a mill ?   

 

This would be way overkill for the trammel, but I LOVE overkill.  

 

Ivandea.  If one used narrow timing belts, would that eliminate a lot of the

Re: Trammel of Archimedes

2022-05-21 Thread 'Curt George' via Legacy Ornamental Mills

Hello Dan.
a timing belt No. but perhaps a timing chain could work.The easiest way to look
at the Geometric chuck is to see a planetary modal. the Sun is in the center.
(1st gear) the speed control is like the Legacy directional gear set. (spins
either left or right.) The reduction gears are like the Duplex gear on the
Legacy to control the speed of rotation. The center hub would be the headstock
of the Legacy. It turns the part on the faceplate. Now there is only one other
thing you need to think about to make a Geometric chuck. and that is the
off-set of the faceplate/center, from the rotation. to make the arcing
movement. The gears in the photo a friend of mine made, I did not do it. He
used a gear machine to make those, (basically its an indexing head on a milling
machine, but his machine was made to only make gears, so its a specialty
machine.)I plan to make my gears with a laser engraver, and to make my gears
out of plastic. I plan to set my system a little different that what Frank did
(he is he one who made the modal I posted the photo's of in my first
posting/reply.) I plan to make the directional gears touch the planetary gear.
If I make the directional gear have three locks for the lever which controls
the rotation, One/right, Two/ left, and Three/ neutral, (for indexing of the
part. and keep the speed control gears on top for easy changeover.) I also plan
to use a 5/8" shaft for the center/ upper hub, to cut down space and make it so
I can use My Shop Smith faceplates with this jig.
Like I said I've done a lot of research on this topic. Its just a matter of
time. before I get it done.
I hope this helps you understand how the jig/ Geometric chuck works?

Ivandea. If one used narrow timing belts, would that eliminate a lot of the

Re: Trammel of Archimedes

That geometric chuck is a fantastic widget!  I have always drooled over 
what  Holtzapffel ornamental lathes can do.  I set up a Supershop lathe to 
mimic some of the simple patterns, but simple is the key word. The 
geometric chuck video reminded me of the Spir-o-graph toy.  Years ago I 
gave up trying to think about linking that but now I can cut gears.  
H.

Your geometric chuck for the LOM is in another class!  WOW!  First question 
(suppressing many others) is how do you cut those gears?  I have a gear 
geometry program to create a printed pattern, but cutting it on the scroll 
saw seems to lack the accuracy that is desirable. They are just spur gears, 
so an indexing head on a mill ?   

This would be way overkill for the trammel, but I LOVE overkill.  

Ivandea.  If one used narrow timing belts, would that eliminate a lot of 
the gears?

RE: Trammel of Archimedes

2022-05-21 Thread bulkeley

I have only used rocklers one you can mount the work and the base on the rotary 
table and let the router rest against a rail as the table rotates but it sort 
of doesn’t gain you much accept the routers lead doesn’t get in the way as it 
does when you rotate it instead of the work maybe I will play with it again on 
the mill someday

I haven't scoured the archives so this, too, may be an old discussion.  Has 
anyone made a trammel of Archimedes for ellipsoid shapes?  It has been a dream 
of mine to be able to do a range of ellipsoid shapes under a router and they 
are not hard to make.  One does not "need" a LOM to do such, but it would be a 
lot easier on one.  And the minimum size would be much much smaller.  

 

Having metal machining now available to me opens up new avenues and eventually 
I will pursue making one for the LOM.  In the meantime,
