Exactly. The 1" tubing is a lot easier to sweat if you step to the yellow can (insterad of the blue propane) since that makes a hotter flame. The M or L tubing is rated at 250 psi in annealed (after sweating) state, if I remember correctly. The ball valves are rated even higher than that.Did you just go through and sweat the joints in the copper like you would for normal water usage in the home?
It's been in place for years now, no problems to date. One final note: be sure and isolate the copper tube from the compressor with flexible line. Otherwise the vibration would likely lead to a failure of the sweated joints near the compressor. I used Aeroquip 12 AN push-on hose and fittings from the compressor to the copper tube.
I also run two compressors in times of high demand (like when my buddy comes over to use my blasting cabinet while I'm grinding or something). I use an isolater (or one-way valve) to keep the higher rated compressor from filling the lower rated compressor beyond its rating.

Re:
Alright, well how bout this. I have a freind who has a 60 gallon horizontal tank and compressor that I could get for next to nothing ($75) it is a 2 stage compressor but it needs a motor. Is it worth going through the effort to get a rebuilt motor for this setup. the brand of the compressor is Marathon (I've never heard of em) and it used to be an industrial compressor which ran on three phase! Could a regular 220 motor work? He said the motor mounting plate is drilled for various motor hook ups! What do you think of that? Knowing what I know about 220 motor and 3 phase (which is nill) I am gonna need some help on this!!

i would hop on that deal, you can easily mount a single phase motor onto the plate. the only think i would do is buy a good rebuilt or new motor, and all you will have to do is match the rpms the motor runs, that is important, most all the same hp motors have the same shaft size, but look into that also, i replaced the ones on my fathers for him awhile back, i got a brand new ge motor out of graingers for 245 bucks, it is a 5hp motor, if this compressor has a 7.5 hp or different it will cost more, but it will be worth it, goodluck
