How big is the item shown? There is nothing to scale it to. Also what is it made out of?
I have a Cummins 7x12, but did look into the 8x14. I think, assuming it fits in the envelope of the machine (and thats not a handle from a battleship made out of titanium) it should work. There are some great sites on the 8x14 which appears to be a great tool. As a word of note, and NOT taking anything away from lathemasters... the 8x14 is currently on sale @ HF for only $439... that is a darn good price!
Fignoogle(sp?) has a good site on the 8x14 and lurks on these boards. I went with the 7x12 in the end because I KNEW that it would be easy to find tooling for it and the cummins tool already came with some nice goodies for a great price ($399). Supposedly the 8x14 will support the 7x12 tooling, but fignoogle said that there is some fiddling involved.
geesch cheeks....give us more info to go by.....that part could be microscopic or huge as Mount Everest......tolerances??......the knurling you can do with any machine that is rigid enough to handle the piece in question....
You can knurl on any machine that will spin the part, period, if you use a scissor action knurling tool. I've seen it done on a drillpress with the tool clamped to the table and the work passing through the center hole.
Getting kind of hard to find those knurling tools though, for some reason.
