Here's a ball cutter I came up with for my 9 x 20 lathe. It can turn
balls up to 1 7/8" OD and it can also do
concave cuts. The cutter uses a replaceable carbide insert so the tool
bit height is "fixed". Three set screws
on the front allow the tool bit to be adjusted left and right. The
cutter really works great , no chatter, very rigid
& super smooth cutting action. I have included pictures &
building
details below.
