Sandblasting
I'm planning on sandblasting my floorpan, both top and bottom, with a sandblaster. I'll also be sandblasting my frame and various parts of my chassis in the future. My compressor is massive and I'm not worried about running out of air while sandblasting. The issue is whether or not this sandblasting unit will suit my needs...
10 GALLON SANDBLASTER
• 2-wheel design for easy portability
• Pressurized design gives 30% more sandblasting power than siphon
• Includes: deadman style sandblasting gun, 9 ft. hose, filling funnel,
shut-off valve, pressure gauge and 4 ceramic nozzles
• Working pressure: 85 to 125 PSI
• Air consumption: 6 to 25 CFM
• Use with 5 HP or larger air compressor recommended
Will this sandblaster be big enough for my needs? It's on sale for $130...regular $180. Please, I need input from you guys.

I've got this one from Harbor Freight:

I don't like it. I agree it puts out some serious sand and works quickly, but it puts out a little too much sand for my taste. I went out and bought a syphon one and am much happier with it; it's a Craftsman. I've only used the HF one a couple of times and now it's just in my way.
My compressor was plenty for it though. I have a 60 gal single stage. I forget the HP at the moment but it was the one from Lowes.

I have a siphon type sandblaster...but I haven't had the chance to use it yet because I don't have any sand or a blasting hood yet. Any more comments on the pressurized sandblaster I'm planning on picking up? I have a 60 gallon husky air compressor, 11.5 cfm at 90 psi.

I'm sandblasting my frame with a $14.00 siphon feed blaster from Home Depot. If that can get off rust and paint then I'm sure your pressure blaster will work even better. BTW, invest some money in a good respirator if you are using sand. I do my blasting out in the driveway so most of the dust lands on the neighbor's cars.

How fast does the siphon one work? Is it really slow? What type of sand do you recommend for the siphon one, because I bought a husky one from home depot a while back. What type of respiator do you use...something like this?

Hey Stinger....the compressor you spec'd, it will do what you need and more. You might want to seriously consider blasting media as well. I sandblasted wood signs for a number of years (as well as various car projects along the way) Sand/silicon carbide for the heaviest stuff (frame, frame components) something a little lighter for the floor pan. IF there are weak spots/heavy rust, the sand blaster will make cheese grate out of in a hurry. the kind of pressure you will get from that blaster will remove metal in a hurry as well as rust.
I used walnut hull media for my engine compartment, removed ALL of the old paint and goo, DID NOT bother at all, the f'glass and I didn't end up with sand in places that are tough to get it out of. The media loses speed rather quickly and did not damage the frame paint at all (got my project midway and they kind of got things a little out of order)

The respirator I have is similar to the one in the pic. I wouldn't use it in an enclosed space with sand since they really aren't rated for silica dust. In my dirveway the dust blows away so the silica danger is less but I still put myself upwind of the spray.

Sandblasting floor pan not a real good idea, its thin to start with and if any rust, very thin. Use a brush wheel to knock off the chunks and vacuume it off a bit, then some phosphoric prep/Etch. It will come out nice and clean and no more material removed than necessary. Paint bare metal with POR15, then a layer or 2 of fiberglass, top and bottom.

74 and 76, I also have the HF sand blaster. It works great with walnut shells, but with play sand, it will come out for a while but then i just get air. How does yours do with sand. Thanks,

Sandblast Booth
I'm looking to make a collapsible sandblasting booth out of some tarps/clear plastic - the frame will be made out of small 1X1 wood. Has anyone here made something like this before? If so, post pics. The floor is gonna have clear plastic on it as well so I can sweep up all the sand and reuse it.

Stinger, I have that same unit in my shop and use it with a Husky 6o gal all the time. It should work fine with your compressor. It will still be pretty time consuming sandblasting a car frame with it though.
For media, I would use aluminum oxide or black magic. Stay away from sand in general for health reasons...bad stuff!!!!
