I searched on the internet and did not find any info on max cut with the
315FC torch. If it will not handle the 8 inch shaft, try searching on
Oxygen Lance. I have never used one, but have seen the pretty pictures.
Yup, 8" is getting up into the oxygen lance territory. They make short
work of big cuts, but use a LOT of oxygen.

I hope no one..least of all Iggy...loses sight of the fact that that
flywheel is hanging on that shaft and HAS to be dealt with PROPERLY
before anything else is done.
I say this, part of my career has been fixing such machines and I
HAVE pulled down big punch presses to change bushings holding that big
assed cam shaft. If one were outdoors, one could shear that shaft and
let the flywheel simply fall using exothermic devices...but
indoors..it presents a hazard to both the floor..and anyone around if
that ******* gets loose. Its a very simple thing..except for the
sheer scale and the weights involved. A flywheel on an 8" shaft can
weigh up to several TONS, though I doubt this one would be more than 1
ton based on shaft size. Having a 1 ton steel wheel 6-10' off the
floor suddenly come loose and subject to gravity..is a nightmare of
biblical proportions.
My best estimate is that the wheel weighs 5,000 lbs.
If it falls on the floor, it goes straight THROUGH the floor.
I will hold it with the big forklift and strap it to the forks.
I have done it once already (no one cared about that building). With a
much smaller press.
Id be lifting that flywheel upwards and putting a small load on the
forklift before you cut the shaft. Better to have the press fall/relax
a tiny bit than take a sudden down load of 2.5 tons.
Yes, definitely.
