Its suitability depends on what you'd like to do with it. For cleaning spark plugs or minor touch up, it might be useful. When it comes to prepping a fuselage for paint, probably not very useful. For the latter, I used a 120 cfm tow-behind compressor, and around 100 pounds of media, and I only blasted about half of the structure.

you have a model you would recommend(is the 120cfm the rating for the blaster)?, or is it a certain type rated by flow? do you like the one youre using now, would you buy it again?

The compressor's not the type of rig you buy Definitely a rental!

The blaster nozzle you have looks like it would be cool for prepping wing steel and small stuff like that. What is the capacity of your current compressor? Mine is 20-something gallons, but barely has enough capacity to hold up to a die grinder.

I think I paid $400 for a local shop to media blast my fuselage. It was worth every penny.

This is a great idea, don't have to buy equipment I would only have to use once. and its done with industrial level tools.

Did they primer it also? if not how much time do you have from the time they finish till you have to get paint on it?

I have a 8 gallon, and it cant keep up. Ill have to upgrade if I was to do painting or anything more then running a drill.

I had a powder coating shop do the sand blasting so no, they didn't prime it. Corrosion spores start immediately so you want to paint it ASAP. My climate is very dry but I started spraying primer within a couple hours of them finishing blasting.

Efficient sand blasting requires a LOT of air. A diesel powered screw compressor would do nicely as it can supply continious 160 lb air with the hose cut wide open.
probably anything less than that you will blast for 1 min and wait for air 8 min. Then --- if you can get air--- then you run out of sand ever 5 or 10 min of blasting.
And the sand has to be quite dry and well sieved in order to flow through the hoses to the nozzle. i have a 3 hp 80 gallon and it cant keep up---

That said- a little hand held blaster with a top sand tank might work well for little parts or welds on small parts. For the price-- go for it. Will still be usefull.
