Here's a ER-40 to MT3 for $25.

Ed,
Do you have a draw bar? I was planning to make one for my ER40 chuck but then I found out that it is possible to buy extra long machine bolts. I bought mine from a local outfit called McFadden-Dale. I'm sure McMaster-Carr also sells them. One bolt cost $15 but it saved me the trouble of machining a draw bar. I added a shoulder washer I made that centers the head of the bolt on opening at the headstock end.

This is similar to what I used except mine was black oxide steel. Obviously a bigger lathe will require a longer bolt.

That's not really a drew bar needed on that ER 40 unit. All you need is something to back up the hold of the taper. A piece of all-thread, couple of nuts and washers will do. The collet is tightened with the nut on the front. I jist use the thru spindle stop I made.

Henry,

I don't have that collet chuck in the picture I posted. I just posted it as an alternative source for someone looking. I have this ER-40 collet chuck for my lathe.

Thanks. Here's the MT4 - ER40 Chuck I bought. I used a 11" x 5/8" black oxide bolt with a a custom shoulder washer I made as my draw bar it works great. I mounted a 3/4" piece of drill rod in a 3/4" collet and found the run-out on my setup was +/-0.00025. I think that is very good for a $50 chuck.



If you need an ER chuck for mill or lathe, the EBay seller I purchased from sells ER25, ER32, ER40 chucks and collets.

I checked out that e-bay seller and their address is in my area, just across the river from Portland Oregon. I am going to see if they sell local as it will save me the shipping fees. Thanks for the heads up Henry.

The same dealer also has the ER40 wrench for $13. Here's my complete setup. It cost me $80. It does have one disadvantage over Ed's chuck pictured earlier. You can only grip short stock while Ed's chuck will allow you to feed long bar stock through the chuck.

Ed, can we see that set-up on your lathe and also hear about how you mounted it?

Steve,

You most certainly can. When I get to that project I will document my butchery with plenty of pictures. Big Grin

Ahh! So your "to do list" is like mine, long and daunting.

Since I don't have any ER-40 collets yet, there's very little incentive to tackle that project yet. And yes, it's long and daunting. Ah, the list that is. Yikes
