And these are the screws I mentioned.

This is the temporary front one until I get a better one made. That taper is the one I referred to i had moved barrel up about 1.5" on that tapper to thread and chamber it. Stayed in .0002 where it started.

This is the system is was referring to early in this thread. finaly got a pic to upload I have held a barrel on the steepest angle of the contoure and still held without slipping Just nice and tight not cranked on it works without stressing the barrel and holds secure. I used a three jaw...

Thanks dmort

Scraping is somthing I haven't done. Not sure how it is done either but interested.

Ya it's always fun making a part from an existing one especially when it's broken and I've seen many of those. 90 percent of the stuff I get now has a parasolid/cad file to make it from. Or I have a print i can draw up a solid from. 99 percent of the tools are carbide that I use at work.

I just got one of those 3/16 carbide bar yesterday and it looks like it will do great and takes the same inserts as my 1/4 carbide circle bar from widia.

No the only grinder we have is a diamond wheel on a pedestal we use for relieving tools

The machine I'm running now is a VTC 300 C with the 48 tool capacity. I believe

Then I'm in trouble because I'm still on the job just not in that shop. I'm doing cnc mill work on a mazak now.

And that happened without jaws sticking out,setscrews, bolt heads.

This shop had three leblonde lathes the middle sized one had a 9"spindle bore and we put a four jaw on the outboard acasionaly Tha is where I got to run the leblonde lathes and they are nice. I remember facing some parts that u could wring together they were so flat.

That weldment I had on the table was a table about 20 feet long that needed pads milled on the same plane. I had it standing up for part of the ops and supported it with a crane. Feed controls in one hand and the Crane in the other.

I think it was a #6 mt and about 6inch diameter. No it had to have been a little bigger Morse tapper then that ? Maybe an 8mt it had a double slot in it one for the drift and one for the key/retaining pin. Sorry it been about 7-8 years

found pic with the spindle hanging out facing some pads on a table

That sounds like a big Lucas horizontal I ran for a few years

Mine is much like the one in the vid but I do have set screws that will stick out, I put jam nuts on them that minimise the hazards but that isn't there purpose. Operating a engine lathe for many years in job shops you learn to keep clear of the spinning hazards. Anyone running lathe should be...

this is what I did to use the six jaw as a three jaw. at the time I was using pie jaws pretty often so it solved a few problems.

Would 416 stainless be any better?
