Thanks Jim,
I don't know what I'll do with just one. Maybe I'll have to get
myself a desk so I can use it as a paperweight.
There are also what look like some type of milling cutters, or
special purpose boring bars in there. The shank is 3/8, then there is
a tapered "neck" and then the end looks like a thread forming tool.
Kind of like those SB thread cutting tools where the 60 deg. angle is
ground on the pereiphery of a thick disk, then when it gets dull, all
you have to do is grind a new flat on the top of the tool? Can't find
any on e-bay at the moment or I'd post the link. But the end of the
tool looks like one of those mounted on the end of the tool. The
angle is formed on a helix though. On the shanks is stamped R.B.- 0
3 B, and there are several, 0 1 B through 0 5 B. Any ideas?
Since this is the Dalton lathe group, I guess I should post
something about that just to stay in the moderators good graces. I've
been trying to make some disks to check some , ahem, imported
machinists squares I bought awhile back. They all fit together
perfectly when I got them, but they all have moved since then. So I
have a 5/8 piece of 12L14 steel that I've turned down to .500 and
all I have left to do is cut it into 1/4" disks so I can check and
adjust the smaller squares.
So that's all for now.
Dave
