Subject: Old air compressor rehab

I recently got hold of an old, greasy DeVilbiss air compressor (Model
220).  Looks like it was built before 1950.  It has an old, large 1/2 hp
GE motor. It seems to work well, producing 70 psi before the pressure
relief valve pops.  It is rated to 100 psi.  (no rating on CFM on the
specs)  I'ld like to use this to as the bases to create my own air
compressor with a tank.  My questions are; 

1) could I use a LP 5 gallon tank (new, as I don't want it full of LP
gas).  What's the psi rating on those LP tanks?  (you know, the kind
that's attached to your bar-ba-que)

2) any idea where I could get a pressure based elec switch so that it
doesn't run all of the time (ie; turn on at 85 psi, off at 90 psi).

3) where can I get another pressure relief valve (for 100 psi)

4) what kind of intake filter do I need (I do woodworking, so dust is a
real concern)

Any other advice?

Please email me as I don't read this group regularly

I was told by a propane "tech" that the releif valves are rated at 375psi

I would reccomend more of a gap, a normal single stage starts at 90 psi
and shuts down at 125 psi. This will give you more reserve.

Any good filter, from a compressor to automotive intake filter.

Just my opinion, hope it helps.  Jeff Trites
