As per title.. my late dad also had this beast ... it is all
crumbling down with rust. .hopefully body work only. plenty of
expensive hoses that would need replacing and also new coolers
it has been sat for ages now unused and ill serviced but my
stupid brain has fallen in love with the idea of fixing it with
as little obsession as possible. it had such a lovely roar when
it was started (straight exhaust pipe 2700 series Ford diesel.)
I also fancy building a small 6x4x2 feet blasting cabinet big
enough to house parts like bulkhead, axles and similar odd
parts.
i think have 250 CFM is a complete overkill unless i adjust the
compressor to build up lighter pressure. since most cabinets run
at 18cfm?
i know my life is out of point. and sense less.. sadly.. any
ideas?
:) i accept every comment even strapping myself to the ingersoll
and jumping off a cliff at this point :)

If you want to do the job just for the love of it, why let logic
have anything to do with it? :)
If you do want the job to make financial sense, that might be
more of a challenge. . . .
Not much point adjusting the pressure I'm afraid. cfm stands for
Cubic Feet per Minute, a measure of flow rate rather than of
pressure. I am not familiar with this particular machine but a
large industrial unit like this is unlikely to compress air to a
higher pressure than a normal workshop compressor. The vastly
higher flow rate is to allow supply to more and larger air tools
without pressure drops. Running significantly below capacity
just means it will be off load most of the time.
If sand/grit blasting is likely to be a marketable commodity in
your area, get yourself a shipping container and refurbish this
compressor and you are halfway towards being in business
:thumbs:
(You can also carve and etch soft metals and stone using grit
blasting. The grit wont touch rubber, so lay a rubber template
over a block of stone, blast it and get left with perfectly cut
letters, or whatever. works on brass and ali too)

An IR compressor like that would run 3 or 4 jack hammers. Is the
other one in the picture, a 365 or a 600, Cummins powered job? I
used to have a 600 running a Halco drilling rig.
That 250 will be well on top for you're plans. They have a 2
stage ,high and low pressure set of veins,from memory. They were
the best available in the 60s and 70s. I can still remember the
UL88 and UL89 pressure regulator numbers.
We also had a a 900 with a V8 two stroke Detroit engine,now that
was bloody loud...........I said ,THAT WAS BLOODY LOUD!!!!!!!!
I am very envious of such a toy.
Hope you'll forgive the reminiscing.
Have fun. :smilewide:
