Re: Making an ER40 Collet Chuck

 

This is for the collet chuck maker. I would buy the front nut.

A collet chuck needs to be made from tool steel not cast iron. The collet will dig in to the cast iron. Its a no no

Cast iron is always a good (but messy) option. You can order a slice of various diameters from McMaster Carr. This is a company that never disappoints, until your check your bill ?. Their products are top notch, selections are wide and deep and they are delivered quickly. The prices match the quality of product and service. I have never hesitated buying from them.?

Jody - Regarding your question about stainless for your project: I have not had much experience working with stainless, but what little I have had has all been bad. This may say more about my fairly limited machining experience than anything else, but I found work hardening to be a real problem.

Re: Making an ER40 Collet Chuck

 

A collet chuck needs a hardened surface where the collet"s contact the taper of the chuck. You can use a oil hardening steel or water hardening. Make sure you do it properly and watch the colors of the steel when you dunk it in. I can walk you thru the process but i need to know the type of steel

What about 12L14 or 4140???
They are good carbon steels, but I'm not sure if they would be hard enough.

Re: Making an ER40 Collet Chuck

 

William, we both have the same thought, if you have something that is "adjustable" than it can get out of adjustment. A solid piece bored out and threaded, done on your lathe will always match your lathe, might need an orientation indicator.

Re: Making an ER40 Collet Chuck

 

I'm not getting why you would make a 2 piece chuck body with a adjust-tru feature. If it's one piece when it's mounted to your spindle and then the inside is machined to the collet taper it would seem that is the best it can get. There will be variables as the spindle is not adjusted properly or has some other deviation. The collets themselves will add a slight bit of run out but you can adjust for every collet you use. So a one piece body with careful machining and perhaps grinding seem to be the best you can get. Am I missing something??


Re: Making an ER40 Collet Chuck

 

I understand wanting the pass thru.

Jody you will certainly get lots of experience there are a number of piece all of which need to fit correctly.

Jody,

the set-true feature is like a 4-jaw chuck adjustment, but at the chuck/plate connection, instead of the chuck jaws.?

It is comprised of 4 set-screws located at 90 degrees from each other. They screw in from the outside of the chuck and they press on the registration boss on the adapter plate. Effectively, they allow you to indicate your chuck while attached to the spindle. once your indicator is close to perfect, you tighten the mounting bolts and you are done.

You can make your first chuck without this feature. Just machine the adapter plate as per instructions (usually, skim the faces of the registration boss and backing surface, the same amount!), drill the mounting holes, install the ER40 chuck and you are done.?

You can always add the set-true feature later, if you want to have a simpler project to start with.?

It all depends on what you make with it. For our daily hobby things, pretty much anything works just fine. For NASA, different story, and many shades in between.?

On the chuck you showed, you lose the most important advantage: being able to feed stock though the chuck because the 3MT taper arbor fills out the through-spindle hole. That might work fine for hobby work.?

You are starting to get the trend? Everything is shades of grey and what might work for some may not work for others.?

Not sure if you're considering building a "set-tru" feature into your ER40 chuck, but if you are, with drawings for doing so.

I used the drawings for building a "set-tru" 5C collet chuck, and it turned out pretty well.?

Why bother with adjustments? I like the ?no adjustment?needed.

So basically you have a 2 piece collet chuck.? One (adaptor) that goes on spindle then the actual chuck that can be adjusted? on the adaptor.

Jody,

the set-true feature is like a 4-jaw chuck adjustment, but at the chuck/plate connection, instead of the chuck jaws.?

It is comprised of 4 set-screws located at 90 degrees from each other. They screw in from the outside of the chuck and they press on the registration boss on the adapter plate. Effectively, they allow you to indicate your chuck while attached to the spindle. once your indicator is close to perfect, you tighten the mounting bolts and you are done.

You can make your first chuck without this feature. Just machine the adapter plate as per instructions (usually, skim the faces of the registration boss and backing surface, the same amount!), drill the mounting holes, install the ER40 chuck and you are done.?

You can always add the set-true feature later, if you want to have a simpler project to start with.?

Making an ER40 Collet Chuck

 

So I'm getting close to start making an ER40 collet chuck.? Guenther (GP) and Steve Haskell have provided a couple drawings and suggestions on the process.? I'm really looking forward to it as it will be some challenges for me.

What materials would be a good cutting material but also hard enough for a chuck?

I haven't cut much stainless, but would this be a bad choice for the amount of machining this will take for a small lathe?

Thanks,
Jody (DFW)

Ice cube trays work wonders too.
Marke them 1-16 or A-Z ?for disassembly -reassembly etc..
Their cheap and store easily

Best,
