Re: Machining both ends (depth stop)?

MetlMunchr:

I uploaded a picture of the adapter plate and collet for the lathe.
It is on my site at http://www.kengracey.com/images/Collet%20Depth%
20Stop.jpg

Looks like maybe I need to make a solution. I was initially looking
for something off-the-shelf. But if I make a solution maybe the best
way it to tab the back of the adapter plate and make an insert to
held the part at a fixed depth.

There is no stop screw in this collet chuck.

Thanks,

Ken
