K-Machine,
That Kwik-Way Model #FN portable boring bar was another good unit.
My father bought his new in 1971, for $1900.
Then later the Rotler.
If the block deck was square, that FN bar made a nice bore when using the low-speed, and of course a sharpened bit.
I still remember the hold down device, with the '3' thrumb screws,,,,,,
it loosened up on me a few times,,,,,,,

.
Kwik-Way,,,,made very good valve grinding equipment too,,,,,
Rich Biebel,,,,,,,,,,you guys must have bought your Kwik-Way equipment off of
Lacey Williams also,,,,,,,,
