i have a handful of odd shaped carbide inserts that appear to snap into some type of holder. i thought i would like to see how well they cut with my 12" craftsman lathe so i took a old china tool stock, the kind with brazed carbides that are cheap, and milled an area to hold the new bit, drilled and tapped a 6-40 hole for a clamp i made out of a small chunk of m.s. and put it in the lathe and tried to cut the threads off a 1/2" grade 5 bolt. no reason, just wanted to try it. well, as the tool was traveling down the threads and taking them off, i could see the tip of the tool flexing up and down. crap, i think i did;t leave enough metal to support the tool, and of course, taking a light cut with carbide is not really pretty either. i probably should stick with has or cobalt and just keep grinding as needed. . .

Why did you make a new base rather than brazing the crack in the old one?
Love the orange. You won't be bumping into that by accident. Great idea for a standThis morning I made a carbide tool holder for some sort of grooving tool
by milling out a pocket and tapping in a screw. It seems to hold really well
so will be testing it soon. Also, I used a junk triangular carbide and silver
soldered it to the opposite end of an old Carbaloy Carbide tool. It turned
out pretty good I think and it is a perfect 60 degrees with a small radius
so itching to try it out on my next threading project. Also I made a height
tool for my lathes. The blue mark is for the Monarch and the red mark is
for the Springfield. Also the base fits in my rotary table and is handy to
position it concentric with the mill spindle.
Also, I did the finishing touches to the wire wheel project so including a
photo of that as well.
