The Home Machinist!

I would have it resharpened. Use it until the carbide is dull, then discard it. Insert type face mills are relatively inexpensive and offer more favorable cutting geometry.

I worked in a small non union shop. The CNC lathe operator was a former UAW member. At the end of a job he would strip all the tools from the lathe. On one rush job we were running the lathe 3 shifts. During my shift we I kept editing the speeds and feeds and got a 4 minute run time down to 2 minute...

Set the sine bar on the tilt table upside down (rolls facing up). Use a height gauge to measure the vertical distance between the rolls.

Oooh! A volstro and a D'Andrea. Lucky Bastard.

I have one. A wonderful reference.

I believe Ziegler and Glenzer companies were bought up. You will have better luck searching for Glenzer. Both tools are pretty similar. There are a few floating holders showing up on flea bay. Another quality brand is Scully-Jones.

The appearance of the fracture surface in cast iron is unique. Broken cast iron pieces fit together without gaps.

They work quite nicely in a 3/4 collet. There are straight shank and MT shanks available. I have an MT3 shank. I don't know if MT2 is available. I have a 5/8" straight shank holder I don't use but is missing the spring and pilot.

Guess I should have noticed there were 2 more pages of replies before adding my 2 cents worth. Other contributors covered the issue nicely.

Shars also sells that kind of face mill. It is rather inexpensive. Another option is a lathe toolholder that hols them "sideways". You can get lead angle turning tools or chamferingg tools. Again Shars sells them.

I just learned it is possible to TIG weld cast iron using cast iron rod. Alternatively torch weld it with cast iron rod using flux. I have been torch welding it for years. In many cases Tig would have been easier. If it is cast iron preheat and postheat with slow cool are essential. On critical part...

I have a small chuck similar to yours. The major difference is that my scroll is retained by a snap ring instead of an interference fit retainer. You might consider cutting a groove in the body for a snap ring. It would simplify disassembly the next time you want to clean the scroll.
