heres a review of a sand Blaster:
Ive got this one from Harbor Freight
110 Lb. Pressurized Abrasive Blaster
Overall its a good blaster that wont jam up on you. its got a built in water trap to keep the sand from getting wet due to moisture in your air line. its VERY powerful. i run mine at about 120psi and it will remove any rust no matter how thick. They say 60-125psi in the description but honestly 60psi is more for removing paint and at 120psi this blaster was strong enough to actually cut through the sheet metal under the rear bumper cover. in general i keep mine to 80-90 psi.
The description says “1.2 to 1.3 hour working time with standard media and tip” which is a pretty big lie. You can empty 50lbs of sand in about 10-15 min of use. This is plenty of time to do something like a gas tank. Also I lay down rubber mats in the driveway and just sweep up any used sand then filter it out with a screen and reuse the sand. So you don’t have to buy sand (which is fairly inexpensive) once in a while.
ive had several sand blasters and this one is my favorite. you have lots of adjustability between the volume of sand you allow to come out of the nozzle at once use and the speed at which the sand comes out of the nozzle. also because its pressurized, not siphon feed, the sand flow is pretty consistent.
Cons: well its from harbor freight so you’re pretty much just paying for the tank setup. For example the mask included is a joke. I normally wear some safety glasses and a paper respirator then put on a face shield over the glasses and mask. Then a large hoodie sweatshirt with draw strings on the hoodie over the top of the face shield. Its not perfectly safe but it works pretty well. also the rubber lines and cheep deadman valves will be wear through eventually by the high pressure and fast moving abrasive sand. luckily deadman valves are cheep and readily available at any hardware store. also the guns ceramic tips will eventually wear out. I’ve always hated the 'gun' style nozzles so instead of buying some new tips when the ones included in the kit wore out i bought a much larger nozzle that resembles this.

because the ceramic inside this nozzle is MUCH thicker i get many more hours of use in-between switching the ceramic inserts.
It’s a great tool to have and is very useful. I used to be the guy with a wire wheel on a drill but this thing saves me a ton of money in both wire wheels and time. You do need a large compressor to run the sand blaster, or you will only get a few seconds of blasting in-between waiting for the compressor to pump the blaster back up to the desired psi. plus it’s a great feeling knowing that you can simply unbolt anything that’s rusty and easily make it look like new.
I’ve also been looking into buying a plasma cutter and tubing bender. Hopefully someone can point me in the right direction, but if not you can bet there will be a review of a plasma cutter and tubing bender on here within a few months.
