1640hd Has Arrived

For a large lathe there is no law preventing you from mounting a smaller chuck on the appropriate back plate to keep the weight to a manageable scale. Keep that 12 inch for the big jobs, use a 6 inch for the rest.
Just a thought.
 
Thanks guys. I have pondered getting a 8" 4 jaw combination for 75% of what we do the other being cylinder work or big pins or shafts. I like the idea of a combination 4 jaw in a 12" to keep from having to swap out chucks, but at almost 3k that's a little to rich for my blood.
 
The machine is still on the pallet but the urge got the best of me so I wired it up and let her run a while at each speed. Then made a few light cuts.

Surface finish was great that was about a .150 pass just to try and clean it up some.
 
It's about .007 out from start to finish over a 6 inch span. Probably just because it's sitting on the pallet and not leveled or anything. Runs great that was 1500 rpm or so with a iscar tnmg insert.

Yikes! I thought my PBA was spendy. :eek:

But you know...If you're making money with the lathe, what's another $3k? (wink...wink)
 
Hey one day.:D I thought pba made a combination but all I can find is oil field combination chucks. Maybe I'm just not looking in the right place.
 
What's the diameter of that piece you just turned? And what material? Just curious.
