Introduction: Make a Footswitch Sandblasting Pinch Valve (Like PAB)
If you heard of the PAB sandblaster gun and those footswitch sandblasting pinch valves, you will want to check this out, because it offers the best of both worlds at a fraction of the cost.
I thought of this a while back and am finally sharing the idea. You can make one based on looking at this video, but I will have plans with all the details and where to get all the parts soon. Please standby. These are surprisingly easy to make and very inexpensive. Eventually I might make a few for people that don't want to make them yourselves. Just let me know.
In the meantime, please watch the video, ask/ leave comments below. Or you can read more about this on my blog here: http://www.glassetchingsecrets.com/blog/sandblasting-foot-switch-free/
