I have the 780 top load from Tip Tools and the vacuum thing. It works great and it wasn't really expensive. Not too big and not too small.

I am about to cut up a 55 gal drum to build my own. For the window, I was going to make a reel-to-reel mechanism where I could wind the window protector by foot or knee bump control so I don't have to stop to clean it. I am thinking some of those HF led drop lamps will fit the bill for lighting quite well. I am thinking chem gloves and denim jean legs for the arms?

Should I build it as a siphon or for pressure? Very different designs I know. My compressor is about a 10 gal, 2 cyl Sears.

So I put mine together and fired it up. THe results are CRAP. I think The abrasive media I am using is too soft. The only media they sold was the glass bead stuff.

FOr the rust removal I am going to need some heavy duty media, even if it kills me!

If you're having problems with the 780 call their tech line.
I've never had a problem. Maybe for heavy rust you should use aluminum oxide.

My rust is not really that heavy. I switched to steel grit and it works, but the spray pattern is so small that this is going to take a lifetime.
The vacuum on the setup does not suck very hard so the media still gets everything. In fact, i tested blasting without the vacuum on and its the same...

I bought a deadman valve to try that instead of the gun style.
It that doesn't work.
I am going to buy play sand and blast that and use an empty parking lot. That way I don't care about the cost of the media or the mess.

Ill wear a good mask and try not to blast too long.
