Sandblaster Answered

When I saw the sandblaster here, I wanted to make one because well, it's cool. The only problem is that I can't find the gun. From what I can tell, It has 2 intakes and one exit nozzle. I did read the instructable, but it didn't say (as far as I could tell). Can someone help?

I saw the instructable and I am really not sure that I got the point. If it was an instructable about blasting patterns on jeans then I understand. Whereas, if it was an instructable on making a sandblaster then it was not very good. Sandblasters I have used have the nozzle(air/water) behind the sand Venturi tube. The reason for this is: to stop the sand(grit) wearing out the nozzle and also to stop the grit from blocking the nozzle. There really isn't any need to direct the sand through a small bore nozzle in this case. Sure you can make a sandblaster from an air blow gun but sandblasters are relatively cheap and reliable anyway, so what is the point?

Looks like an airbrush, Venturi-effect sucks up sand. However, I didn't spend that long looking at it. L
