What are the differences between the Powermatic 45 and Powermatic 90
lathes? Here's what I've gleaned so far from the net. Much of the '45
info came from a pdf manual I found at oldwwmachines.com or.net. Is any
of it wrong? If you have a manual or can otherwise can help me fill in
the blanks, I'd be grateful.

Thanks,

Jim



Powermatic 45
-----------------
swing: 12" over bed; 16" over gap; 8" over tool rest
(Some folks claimed only 10" over bed;
The 1969 manual says 12", but it contains other
inconsistencies, also. E.g. dwg says 17" over gap,
and gap width is different in different places)
bed: 60", 39" c-c, 4-7/8" gap (3-1/4" from faceplate)
OALxWxH: 63" x 16" x 46-1/2"
motor: 3/4 HP; 1800 RPM
speeds:
variable speed: (5) 330-2100
step: 600, 1100, 1800, 3000

bo ?

(is that right??)

Powermatic 90
-----------------
(I'd like to do an item-by-item comparison with the
'45, but couldn't find as much info on the '90. Much of
this is guesswork.)
