Some time ago we had a job to turn a 20 inch by 6 foot
chunk of steel on a Monarch lathe with 18.5 inch over
the carriage. The first cut was 1 inch deep to get to 18
inch diameter to go over the carriage. The chip was
about 100 feet long before the operator broke it
deliberately, deep and slow pass but it worked
perfectly.
I'm missing something - HOW did you turn a 20" piece with
18.5" of
clearance?
A 20" dia piece needs 10" of clearance. 18" dia needs 9" of
clearance. 18.5" over the carriage will handle a 37"
diameter!
Let's get it right, guys. :) phil k.
Guessing... move carriage to the right of 20" piece. Make
sure cutter
is ahead of the carriage and you're cutting off enough
material to
clear the carriage as it advances...
