   I'm sure you are all tired of the saga of the built to "a" spec Ingersol   
   Rand compressor from Craptor Supply.  The one that killed its own motor   
   in a year.  The one others have reported catching on fire.  The one I've   
   concluded only worked as long as it did because the thermal protector   
   had to be defective or disabled in the original motor.  (Which is   
   probably why some caught on fire.)  The one that tripped the thermal   
   constantly on one replacement motor, and the breaker and/or thermal on   
   the other.  The one I've been keeping running with an under sized motor   
   pulley.  Never mind the debacle with the after market warranty company,   
   or the repair shop who reported the repair complete without ever   
   visiting my shop.  Even with a much smaller pulley it still trips the   
   thermal protector from time to time.  Mostly because I think it has to   
   run longer when it cycles on with the smaller pulley, and when I have   
   several machines running, all of which use air for various things, it   
   has to cycle on more often.   
      
   Mostly I can get by for now.  In the last few months I've only had the   
   thermal trip on me 4-5 times and I run the shop every day.  Still   
   sometimes I run complex operations which can be several hundred lines of   
   code on a single tool.  This gives me the opportunity to run an errand   
   or go in the house for lunch.  It would cost me more than the cost of a   
   compressor if an ISO20 quick change spindle air seal fails and sucks   
   coolant up inside the head as it cools down.  Okay the odds of that are   
   slim, but it keeps me up at night anyway.   
      
   I had decided to bring my dad's compressor to my shop and keep the IR as   
   just a backup.  They are functionally similar except the IR has a 5HP   
   motor and the one at my dad's shop has a 7.5.    Well, that is still the   
   plan, but those compressors are heavy and I don't have anything out at   
   my dad's shop (60 miles away) to practically lift his compressor to load   
   it into my truck or even onto my low trailer.  Oh, I am sure there is a   
   chain fall out there, and there is an old a-frame laying out back, but   
   his shop is a quonset hut.  No beams. The a-frame will eventually get   
   moved to my shop, but its freaking heavy.  I don't even think I can   
   stand it up without the help of a lift.  I know I used it in my youth to   
   pull more than a couple V-8 engines.  Scooting it on concrete when its   
   on its pads takes a little effort unloaded, and with a big block 360   
   hanging from it a bit more effort.  Standing it up in the dirt and   
   dragging it around... Anyway.  It will get done eventually, but not   
   today or tomorrow.  When I do I'll probably trailer my tractor out there   
   to do the job with its loader bucket.   
      
   I just ordered a 7.5 HP compressor duty motor for the IR.  IR actually   
   sells a very similar compressor with a 7.5 HP motor on it at about 3.5   
   times the price of this one.  Then, since I already know all the parts,   
   I ordered a new hub for the original pulley to fit the 1-1/8 shaft on   
   the new motor.   
      
   I quit screwing around with those 5HP motors.  Now I have not one, but   
   two unused single phase 230V "5HP" spare motors.  Maybe I'll make a   
   couple big belt grinders for erasing the bumpy spots on mountains.  If I   
   make a belt grinder or three, which is part of my planned projects, I   
   plan to use 3 phase motors for speed control, so not really with those   
   5s.  I guess I could build a sheave stack, but turning a knob is so much   
   easier than moving a belt.  FYI:  I do have three belt grinders already.   
     a 1x30 and a 1x42 that I use almost everyday for conditioning and   
   de-burring parts.  The third one is on a shelf...
