I just unpacked one of the greatest surprise Xmas gifts I've ever received - a 1955 Magna Air Compressor.
I read up on it previously in the link below:

as well as Chapmanruss' excellent deep dive into SPTs:

It will be interesting to get this working on my 10er, I believe the first step would be to buy a Mark V SPT mounting adapter for 10ER via Skip.

I was wondering; could this possibly be used for sand or bead-blasting?

Nice present.

As for bead blasting no not even close. You need A LOT of air for that application.

Noted. I'll stick with spray painting for this one and keep my Central Pneumatic 150 PSI for low-level bead blasting.

Yes, it's the air volume issue, not pressure so much. A tank added to the Magna compressor might allow it to work, but if you have a larger compressor and air tank might as well use those. I have a pressure pot I bought used, needs a new valve on the output side, but using a siphon blaster inside my small cabinet works better than expected. I had the Harbor Freight portable sand blaster for a number of years, found it rather weak, but should have realized the hose it came with was too long and wasting all the pressure. With the relatively short hose inside the small cabinet the same type of siphon gun works rather well. So I think with the addition of an air tank, like a portable air tank like this nice aluminum one from Harbor Freight or any of the other small portable tank, then the Magna compressor can probably be used for a reasonable amount of abrasive blasting using most media.

This is also a good time of the year to pick up Harbor Freight items on sale. A lot of sale items have limited supply in stores which sometimes indicates the product is being dropped by them.

Ed: Thanks for your feedback, and explanations. You've also solved a longstanding issue for me: I have the same portable sand blaster and suffered repeat clogging while using it. T'was the long hose killer all along!

Thanks for that, seems so obvious. Next time I'll use a shorter one. Incredible deal on the aluminum tank! I am quickly becoming a Harbor Freight fan.

Scott,

A nice addition to your Shopsmith/Magna Tool Collection. As John and Ed have already commented on, use your other compressor for working. Being 60 plus years old it will not be as reliable as your other compressor. As for replacing worn parts they are practically non-existent now. I can get air out of mine but once restored they will be "museum" pieces.
