Note: You can now download my sandblaster plans here.
It seems there has been a lot of people wanting to make a sandblaster themselves and I usually recommended to just buy an inexpensive one such as a Harbor Freight brand.
But lately, I got an email from someone in another country with a different marketplace. I am not aware of the best places to get these from other countries. Also, for anyone’s information, the plans on my site are for pressure pot modifications to fix abrasive flow problems. So if you’re looking to make your own pressure pot sandblaster, I included this video to show you an example of the anatomy of how it’s setup.
So in words, you have a tank filled with abrasive of your choice and it gets pressurized with air. Now Updated: I have now created plans which shows people how to use an old propane tank and weld a top cap on. Its kind of interesting so you might want to read about my do it yourself sandblaster plans here.
Then an air line splits to the tank and the other half goes to the bottom of the abrasive mixing valve as seen in this picture. Another hose is attached at the other end of the mixing valve with the nozzle at the end. Any questions, just ask below.
