That's one thing I've got some of too, but considering I've got maybe 10 
bucks in it, I'd look foolish crying about it. I also am belt driving the 
A chuck, which sits in its own cheap ball bearings. My major accuracy 
problem is caused, I think, by an error in the armatures ellipse, it is 
printed, including the shaft hole and its dflat, and the theory is that 
the dflat may be causing a thou or so differential in the height of the 
ellipse, the motion can be see to vary some in speed on a motor 
revolution cycle. The overall error I'm not equipped to measure 
accurately, but I'm guessing it might be 30 arc seconds max.  That is 
still more accurate than one can set the compound angle on a lathe, and 
until I grow some experience, its main use might be sharpening HSS lathe 
tools using a 1200 grit CBN wheel on that mill at a leisurely 18k rpms. 
HSS destroys diamond, and vice versa, but CBN contains no carbon, and you 
have not used a sharp HSS lathe tool until you've done it with CBN, Cubic 
Boron Nitride. Your ground faces will have a finer, smoother finish, no 
brittle wire edges to dull rapidly, than a brand new stick of HSS has 
OOTB. If it was big enough, you could use it for a shaving mirror.

That printed part is simply pushed onto the motors shaft, after the 8mm 
shaft's existing d-flat, has been widened until the caliper says about 
6.5mm from d-flat to back side of round. Every time I print one, I am 
reducing the 8mm hole, which started at 8.4mm because my print has a .4mm 
nozzle, by .05mm and its tighter and better each time. The pressure from 
the d-flat is pushing it off center. With an 8mm shaft, and only a 1NM 
motor, I've stopped the motor several times w/o damaging the press fit. 
No hub, its just printed PETG. Running on the kitchen counter for about a 
week now. With enough holding torque to let me carve steel square threads 
in a 1" or bigger rod. Not as pretty as Nooks, but usable. :o) I'm 
thinking woodworking bench leg vise bolts. But those might be maple wood.

And I'll have fun doing it. Cheap.

Re: [Emc-users] ER-32 Collet Wrench

[John Dammeyer]

Thanks Gene,
Amazon says it will be here on Tuesday so doesn't look like it will be an 
issue.  

The bigger problem for me at the moment is I put a dial indicator on the 
harmonic drive output hub and used LCNC to spin the A axis.  I then radially 
measured 0.0015" deflection and same with the face which also had 0.0015" 
change over one rev. 

Maybe it's dirty inside or has been reassembled poorly.  But that's a lot of 
runout I would think.

John

I don't see any good reason that wouldn't work.

I'd think, at 3/8" thick, designed in openscad, printed in PETG, might 
get you by until a good real one arrives.

I'm late to this party, my e-mail server was one that got attacked last 
wed morning at 3AM, and is just now coming back to life.

That probably means that the item is in stock in Mississauga and it must be
shipped from there to the distribution centre nearest you. I sometimes get
similar, surprising, delays.

Re: [Emc-users] ER-32 Collet Wrench

[John Figie]

I made my wrench about 12 years ago - or more. It is just made from mild
steel heated and quenched in oil just to put a black finish on it. It has
worked well in my hobby shop and the teeth show no signs of wear. It seemed
like the ones I could buy at the time were too expensive and I was probably
feeling guilty for exceeding my budget so I made one one day. But now I
think I would just buy one. It was before I had CAD so I probably spent
more time writing the program than actual machining. Drilled the holes
first then bolted to my 1-2-3 blocks held in a 6" vise.

Re: [Emc-users] ER-32 Collet Wrench

[Todd Zuercher]

I think you can find even cheaper ones on Amazon, the hook style ones are 
around $8US, and the same style you linked to can be had for as little as 
$11US.  All with free shipping with Prime.

We normally use a hook style end on a torque wrench for tightening (to 90ft-lbs 
on ER40 collet nuts and 80ft-lbs on ER32), but use the style linked to below 
(with a cheater pipe for the ER40s) for removal.  We have managed to rip the 
teeth off of a couple of them over the years.  We also have a number of SYOZ-25 
tool holders, they can only use the hook style wrench and can't take as much 
torque as the ER, but don't need it either with their steeper tapers.

So my Collet chuck arrived a week or so ago.  Today the ER-32 collet set 
arrived.  I no longer have an excuse for not completing my 4th axis driven by a 
real harmonic drive.  (Well it is raining and can't cast).  So I have drawn up 
the face plate adaptor and that looks to be a pretty easy LCNC project for the 
mill plus a bit of lathe work.

However, I foolishly did not order a collet wrench.  This seems to overall be a

collet.  I suppose I could mill out the profiles in some oil hardening steel, 
then file the teeth to have straight edges.  Finally harden it.

Alternatively make it out of 1/4" or so steel plate (or even aluminium) and 
drill and tap holes for screws to protrude out where the teeth are.  Turn down 
the screw ends to be smooth or even square and lock the screws in place.

Looking for suggestions here.  Don't really want to wait 2 months for one 
wrench with either low price and horrendous shipping or high price and low 
shipping.  Cost ends up being the same at about $28.

Re: [Emc-users] ER-32 Collet Wrench

[Stuart Stevenson]

The length of the handle is purposely short as most people will use way too
much torque to tighten the lock nut. Exceeding the chuck manufacturer's
torque specification will not help in the holding capability and will
result in less accuracy of the resulting assembly. Over torquing the
assembly will begin to damage the components. The interface between the nut
and the collet will usually show damage first.
Just my 2 cents
Stuart

Looks like you could cnc it then use a bandsaw to cut the inside corners of the 
teeth.

This style would be easier to machine on a mill.

I have only ever used hook-wrench style ones. It hasn't been a problem.

Or CNC then file out the corners of the teeth, by hand.
