Try MBS Model Supply: http://mbsmodelsupply.com/ (http://mbsmodelsupply.com/).  Nice guy.  I always forget to call after 5:00PM Kansas time, and he's still nice to me.

I think his sleeves are a bit smaller than what you're asking for, but they should still work.

Thanks Bob but, that is still thin wall tubing. I may have to grind a few out on my lathe.

Actually Mcmaster Carr lists Fabrication copper tubing at 1/8 inch OD and 1/32 wall thickness
(.125 OD .065 ID).

Downrigger cable crimp sleeves are really heavy duty and made from stainless steel. Try your local gander mountain or cabellas

Grinding on a lathe is quite common and any machinist worth his salt knows how to do it ;). It provides the best surface finish and the highest precision parts.  Try looking up tool post grinder in Google or YouTube and you'll see.

Paul, I spent a better part of my working life in manufacturing and machine tools.  I was a Field Service Engineer and Service Manager for a well known machine tool builder for 18 years. I owned my own manufacturing company for 21 years.  I have many, many years of lathe experience, both manual and CNC.

I am well aware of tool post grinders.  I am also well aware of how grit can get under bed ways and seals and shorten the life of a machine.  Even polishing on a lathe with emery cloth is not a good practice.

There are machine tools designed for grinding and there are machine tools designed for turning.  Grinding on a lathe is something I would never do.

As far as your comment, I thought it was a mistake in describing material removal.  Not everyone understands the application of turning, grinding, milling, drilling, boring and so on.  Apparently you do and choose to grind on your lathe.  My apologies for second guessing your intent.
