Since I built the QCTP , I've discovered a whole new set of
capabilities for my 72+ year old PowerKraft lathe . I already had a 1 hp motor on it , because it was free ...
It started with a boring bar clamp post , and it is so much more
rigid than the lantern . Less singin' and a nicer finish . Then I made
the QCTP , and got a few 5/16" shank indexable cutters . I can cut a
bigger chip faster with a better finish in most cases now .
So I just ordered a 7 holder set of indexable boring bars and
threading and cutoff/grooving tool holders . And a supply of inserts , because sure as night follows day I'm going to tear up a few while I'm learning how to use this stuff .
Wish me luck !

If you ever need a little more rigidity eliminate the compound.
Replace it with a solid block of steel ground flat.
Sometimes I crank the compound all the way out and snug the gib
screws a bit more . The biggest source of flex was the lantern toolpost
and the quick change has eliminated almost all of it . Parting off is
still sometimes iffy , but ya just can't have everything .

I didn't mean throw it away. Just only install it when you need it.
