Have any you guys used the cam bearing thrust kit to prevent your reground cam from knocking? I am making a jig to be able to face the bronze washers and was wondering how anyone here has done it? It is thin like a rear axle thrust washer so hard to hold in lathe.
Anyone solved this? Thanks Dan

look up "step-collet" on the internet or eBay
buy a cheapie, machine it to your OD and face away
they're one of the unknown, unsung heroes of the lathe-world

this is bigger than you need, but a handy size...you can cut any number of custom, shallow steps into it to hold a whole array of thin parts

I have a bunch of them in 3C for my old South Bend

I wouldn't be without them

I was going to try and make something, but I think I will order some of those and give it a try.? Thanks Scott for the idea. Dan

You're welcome, Dan

as you probably know, keep the plug in while machining it to a dead-perfect fit to your part, and when you do, machine a very small back-rake into it and it will grip just fine when you push the plug out and tighten it onto your part.
