you could always run the compressor in the basement and run a hose to where evey you are working...if you want to minimize pressure loss than you can use garden hose and/or put another tank where you are working. (old grill lpg tanks have 3/4" npt threads on them and work well as a buffer)

Where did you find your heavy duty motor? I am going to rebuild my compressor with an Eaton pump and I have the "15 amp" motor which I know will probably burn up in no time. (Looking for a motor that I don't have to sell a kidney to purchase)

I got lucky and a teacher/family friend gave it to me, he works as a contractor during the summers and it originally had a CAT pressure washer pump on it. he said that he had never been able to get it working and didn't want to keep wasting time on it.
you could call eaton, they used to sell single phase motors on there e-bay store. last summer i think a 220V 5hp single phase motor was going to be $350 shipped to iowa.
I just thought of something about runnin' this compressor without a tank or control valve....my sandblasters work when I pull the trigger much like a spray gun....too much pressure is bound to blow the hose off....this compressor of mine has a 12" pulley/flywheel...whatever it's called...I have a regular air pressure tank from a "BRUTE" compressor that I was gonna' repair because of a burnt out reed.....I'm thinkin' now if this motor that I'm gonna' try is duel voltage....I'll run it off the dryer 220 volt....just have unplug the dryer cable and use it to run my compressor....and like mentioned.....use my two 50' lengths of rubber air hose and run it outside to where I'll be using my suction type blaster/yes I first bought a pressure type and found the suctioned type was more suitable....I guess you could say keep works best..I owned an old Craftsman Compressor years ago that had duel voltage options worked much better on the higher voltage....so this is my new plan....the specs for my compressor call for a 1-1.5 hp electric compressor duty motor....I just need to know what size motor pulley to use with this compressors 12" pulley....thank for all the suggestions it really is helpful...like I mentioned if this electric motor burns out....I can return it as I'm going by their specs for motor size hp....I just return it spend the extra $$$ for a larger HP electric motor......you guys are a great help....I'm also runnin' on a very tight budget......I work for the government I guess..... cause they are the ones that pay me my old age pention :laughing:.....take care....Ampa
I did not use any copper or finned copper to cool my air, i ran it through an old compressor tank, then 100' of nice 5/8" rubber garden hose.
what speed do you want to run your compressor at?
if you take the inner diameter of the pump pulley times the rpm you want to run it at divided by the motor rpm you get the inner diameter of the motor pulley.
that is the valve that I use for my always on compressor, you turn the knob and once you set the pressure to start bleeding air off at it will keep the pressure with in 10psi of that no matter what the air demand is.
Paton when it comes to math...it was my worst subject....okay I need help on this....the compressor has a 12" pulley runs 1400 rpm to give me 11 cfm@90 psi...the electric motor has a 5/8 shaft and runs @ 3450 rpm...the 12" pulley uses a single V type belt....this with be another measurement that will have to be figured out....thanks in advance.....Ampa
ok, i think that your 12" is the outside diameter on the pump, what you need to measure is the distance from where the belt touches on one side to where it touches on the other, i think this will be 11-11.5".
so for a rough calculation... 11.5*1400/3450 = 4.67" add about 1/2" to get 5 or 5.25" od pulley.
I forgot to mention belt width which looks to an "A" width......so I'd be looking for a 5-5 1/2 motor pulley correct?.....I could maybe measure the motor pulley on the complete factory compressors with my same compressor pump when I buy the 1.5 hp this comming Tues...I'm only saving $30....sale price is $149 reg price $179.....I want to get started building this before spring....been tryin' to get out and go brook trout fishin' for the last 3 years...I promised my lady that we will go for sure this year.....thanks and take care....Ampa
Just to inform all you guys that my compressor is up and runnin' pretty good....pumps up that 10 lb tank in less than a few minutes....I'm not too sure if it matters which direction the compressor should run...on Rio Grande's copressor....his electric motor is on the left while mines on the right....I installed a 3 1/2 " cast iron pulley on the 1.5 electric motor...I had to use a 60" belt........it's very quiet runnin' alot quieter than the small direct drive CH I bought new last year....the motor don't get even warm....the compressor gets quite hot on the outlet copper tubing I bought and used compression fittings....other than my terrible welding is not the greatest...but it's holding together just fine....Thanks to all you guys who helped me along on this prodject....I'm happy with it....take care all....Ampa :thumbsup:
