Here's my thoughts: find a properly sized 220V compressor and get 220V out to it.  I have a 220V compressor with a large tank and it runs almost constantly when I'm using the blast cabinet.  Sand blasting runs on volume.  You'll be surprised how fast that volume gets exhausted, and when the compressor can't keep up it sucks.

Every time I've tried to use a creative work around to what I've really needed in the end I've discovered that I'd have been happier and bucks ahead to just do it the right way up front. 

Where's the shop?  Detached garage or attached garage?  If its detached you may just need to run a new line from the house to the shop.  To avoid the cost of having this done get an electrician to connect the ends and size the wire and trench and lay the wire yourself.  There's UFB wire (direct burial) or you can run PVC conduit and single conductors.  Is not rocket science and you only need to dig down 2'.  You could rent a trencher or dig it by hand.

If its attached you just need to run a new dedicated 220V line from the panel to the garage.  Where this could get tricky is if everything is finished surrounding the panel, but a good electrician should be able to come up with a way to route the wire and make a minimum of holes that have to be patched.  I'm assuming the panel isn't in the garage, so its probably in the basement or somewhere on the first floor if there is no basement.  The simplest route is usually to get it up in the attic and run it across to the garage that way. 

Alternately, if you're already thinking of using gas power, just get a proper compressor and power it off a generator. 

If you do not have 220v power available, consider buying a 110/220v gas powered generator to power the compressor.  Then, you'll also have a backup generator if you're in a blackout. 
Just a thought.

Planning for the future is always smart.  I ran two conductor to my little 10x10 shed when I built it.  Why?  Because I don't know what I might need to do there in the future and I could easily add a 220V circuit if I ever needed to run a welder. 

I also hard piped everything with copper a couple years back.  That was when copper was $0.98/foot though, now its more like $6/foot.  It would be a much more expensive project today, but there's no concern about the copper ever degrading like plastic pipe does, and soldered joints don't leak if you know how to sweat pipe together.

Done!

Thanks everyone on the help and suggesting a Generator to power the compressor.

Large Air compressor  60 Gallon  https://classifieds.ksl.com/listing/65122607 Im going to purchase this tank owner states the tanks Air pump is under rated. I have found what I believe to be a really good pump for the tank maybe over kill. It has a rating of 20.6 at 40 CFM https://pittsburghsprayequip.com/products/industrial-air-6-hp-single-stage-hi-flo-3-cylinder-replacement-air-compressor-pump-20-6-cfm-40-psi  a smaller replacement unit for a chicago pneumatic 7.41 at 100 psi 155 psi max https://aircompressorpartsonline.com/new-pump-assy-b3800-p-635.html

For the gas powered engine https://www.harborfreight.com/65-hp-212cc-ohv-horizontal-shaft-gas-engine-epa-69730.html 

Only things I would be lacking throttle control, pressure switch gizzie, belt and guard.

An option for me to save maybe some cash is get this bulldog honda powered gas compressor. I can scrounge engine pressure valve throttle control $240.00

I think it would. My home made tank pictured above is 31 gallons. I have used that type of hand held blaster as well as with a home made cabinet blaster that required “catch up time”.

Thank you Rudi Thats really cool you were able to pass it down and the legend lives on. I would like to be able to pass down some of my tools to my future kids I dont  have any Kids right now.

Keep in mind that the larger cfm’s will also have larger tubes/piping going into and out of compressor tank.

Take a look at how IR and Dewalt 60 and 80 gallon compressors to see what I’m referring to.
Tractor Supply is only place locally carrying larger electric compressors.

I noticed the larger compressors draw about 20-22 amps at 240 volts.
The larger HP motors usually run 240v only.
10 gauge wire and short runs.

When three phase motors where cheaper you could build a three phase convertor from a  three phase motor . say you wanted to run a three phase  compressor on single phase by using the pony motor to generate your third leg .You would need to spin he pony motor to start but it would run and generate your third leg to run or compressor .

220/240 is the 2 phase of 110/120.

Motors like these were made to be universal so they could be used around the world.
Less inventory.

Yeah, 208 is a totally different animal.

Technically, 220/240v is not 2-phase as both hot legs are in phase with one another.  They run off one phase (of a 3-phase system) through a step-down transformer that is center tapped to provide 110/120v from each ‘hot’ leg to the center tap (the ‘neutral’), and 220/240v across the hot legs.
And yes, 208v is different as it is from a 3-phase supply.
However, this is getting too deep for this post.

 

220...221... whatever it takes.

The 220 volt on a home is off 1 phase but with the center tap to ground the 2 120 volt legs are 180 degrees out of phase. If they were in phase you would measure zero volts across them. Now these fake 3 phase systems put a large capacitor off one of the legs that shifts voltage approx 90 degrees to develop a third phase and make a 3 phase motor spin. The phases are not 120 deg out of phase like true 3 phase power nor do I think the capacitor tap can supply the current the other legs can. I agree with TKO I would stay away from this.

Wsinsle - we can take this discussion off this post and continue with PMs or email, but the phase shift occurs between primary and secondary side of the transformer.  As the secondary side of the step-down transformer is one coil that produces the 220/240v end to end, with the center tap of this coil providing 110/120v to each end leg, there is no phase shift.
I agree with staying away from 3-phase convertors.
