I bought it to remove some paint from a foundation and no medium I tried would go through the nozzle no matter which tip I used. I spent 40 hours trying to get it to work and ended up bringing a company in to do the job for me. They had a unit on a trailer that got the entire job done in less than an hour. Even at minimum wages for me and my helper, I wasted over $1,500 just trying it. I might work in a box but isn't made for what I thought it could do.

It's great for small project . Meaning small

Works ok, but can't even run finely filtered sand through it without clogging immediately.

very fast shipping make my job more easy
thanks

This is the same blaster sold by a dozen different brands. I bought my locally and assembled it. Read the reviews all over the web for all the different brands and you can get some great tips on how to make it work best. It's entertaining to see different brands have different results or different customers have different expectations based on the different prices they pay.

A couple quick comments. Just bought it yesterday. Looks good. I like the build quality. Looking for the design I think I'll add a generic manual choke cable to move the lower valve (19B). Everyne that says they had success with it says that you really only need ot open the 19B valve halfway and that it only works well with 80 grit or finer blasting media.

Means I'll only have to drill a small hole in the valve handle and clamp the choke knob to the sandblaster handle.

For the play sand users - I used to borrow a big sandblaster from a fellow permanently on disability who had used silica sand in his blaster for a while without enough protection for his lungs. He reported that it felt like he was permanently sick and had been for several years with no expectation of ever being well again. He was in his thirties. Read up and see what you think about it. Wikipedia has a great article on it.

I'm using this blaster with a 60 gallon Campbell-Hausfeld ~5HP air compressor. It's a single stage compressor. It does a fair job of keeping up with the blaster for a while but eventually I do have to stop and wait for it to catch up. If it'll blast at 80 psi (don't know yet), then there is less volume of air being consumed so the compressor might keep up longer. I have not had time to experiment that much yet.

Have always used tarps and a small salad colander for sifting my sand/blasting media for reuse.
The compressor pump itself is not big enough to stay ahead of the sand blaster for too long. Being that this is only a hobby rig, I can deal with it. If I was making a living with it - I'd have bigger equipment.

The finer 80-grit garnet that one reviewer mentioned works best. Anything more coarse leads to clogging. I think high humidity will make a huge difference (problem) later in the summer too. Make sure your compressor has an inline dryer too. The sandblaster has one as well of course but having them in both places is worthwhile.
For a helmet I use an old welding helmet with a clear glass window that has a scrap of leather taped/glued to it to keep the grit out of my shirt. Either way its a dirty job but easier and faster than doing it by hand.
