Title: Re: DIY Sand Blaster
Post by: classixs on April 13, 2019, 12:36:45 pm: Been looking for walnut material myself as well, as i would love to test it out, but can´t to locate any supplier here.

I´ve generally used blasting glassbeads in my cabinet.
I find that glass does a very nice job, leaving a smooth matte surface behind.
It´s lighter than standard blasting sand, doesn´t stretch thin sheetmetal as easily as sand has a tendency to do, while still being capable of removing quite severe layers of rust and paint if necessary.

Post by: SlowArrow on April 11, 2019, 12:32:20 pm: I wonder how much you could change the result by using different media: fine sand, course sand, and maybe even something like #9 birdshot. We had a company come in and do some careful blasting of some sensitive equipment that had some degree of contamination using ice (basically a frozen mist). It was a very mild abrasive and didn't add to the contaminated waste once it dried.

Anyway, it worth experimenting with the different media options.

Thanks for the video. I've seen something like this done before, and they seem to work pretty well. What air pressure did you run?

120psi just make sure your outside as you don't want to be breathing sand in (just the same precautions that go along with everything else we do in our workshops).

Neat idea Jim and works well - only question I would have is how long the nozzle will last as I see the commercial ones are usually ceramic.

I'd say a long time Larry.

The gun was only around the $5 mark, comes with two steel nozzles and the sand is travelling along the nozzle.
