Collet chuck basics

[Golem Pens]

I'm making the jump from a wood lathe to a metal lathe - got a South Bend 9C coming this weekend - and I'm planning ahead to the tooling I need to buy. Making 3 piece fountain pens.

I'm used to using a Beall-style ER32 collect chuck on my wood lathe. Looks like I can get an adapter and chuck for using the same collets with the SB9. Is that normal procedure, or do folks usually just run 3 and 4 jaw chucks? Is there another workholding method I should look at instead?

(Also speccing out a quick change tool post and corresponding indexable carbide cutters for first purchases).

Thanks!

I use my full set (32ndths) of ER32 collets almost exclusively & HSS tooling 75% of the time.

Thanks Rick, I'll likely be putting that on the list then.

Planning for carbide instead of HSS mostly because I'm not set up for grinding yet.

I run ER332 on MT#3 collet , two chucks one 3 and 4 jaw set-centering and 6 inch independently adjustable and reversible. use 3/8 and 1/2 indexable holder with carbide inserts.

You can just get another Beal chuck, with the 1.5x8 thread. Lee Valley, I think is the only one that carries one. The one from PSI, only comes in 1x8.

The other option is to pickup one of these;

Mount the back plate to your lathe, then machine it to fit the chuck plate. This gives you the best accuracy.

Oh I missed that Beall does a 1.5x8, that's great (looks like I'm using the PSI one now).

I was looking at this as well (and I'll be getting a tool post from them as wel so I don't have to modify the carriage) https://bmpartstech.com/product/south-bend-9-light-10-er32-chuck-collets-with-1-1-2-8-adapter/

Although DIYing it for precision DOES sound good. Just not sure I have the skills/tools to do that properly yet.

Since you say you don't have the skills (yet!!!!!) to machine your own back plate then I would get the Beall with the 1.5"x8 threads, here's the link
