Sandblaster part 6

The parts required for the sandblaster are the following.

• 1 empty propane tank.
• 3 1/2 inch ball valves - one for inbound air supply, one for regulating sand flow, and one behind blasting nozzle
• 2 1/2 inch npt male thread hose barbs - to fit blaster hose to tank and nozzle
• 1 1 /2 inch pipe "T" - for the air manifold at the top of the tank
• 1 1/2 inch pipe cross - for the sand supply at the bottom. The cross allows for a tank clean out.
• 1 3 inch pipe nipple cut in half - for the filler neck
• 1 3 inch pipe cap - to cap the filler neck
• 1 1/2 inch pipe plug - to plug the clean out at the bottom of the tee
• 3 1/2 inch close fit pipe nipples - one to thread the cross to bottom of the tank, one to weld onto the tank for the air supply, and one to between the dielectric fitting used to hole the nozzle, and the valve to control sand flow at the valve
• 2 1/2 inch pipe elbows - to rout rigid air lines from the air manifold (1/2 T) to the cross at the bottom of the tank
• 1/2 inch pipe to fit air line - rigid air line
• 1 1/2 inch dielectric fitting - to use for attaching the ceramic nozzle
• 1 1/2 inch union - to allow the rigid air supply to be threaded into place
• 1 3/4 inch to 1/2 inch reducer - to adapt 1/2inch piping to 3/4 inch thread where propane regulator was
• 1 1/2 inch to 1/4 inch reducer - for pressure pop off
• 2 wheels
• misc steel for legs and handle.
• 1/2 id rubber hose for the blaster hose (I used some old washing machine supply lines.

The majority of the fittings were salvaged from a house re-piping project.

Sandblaster part 5

This weekend, I added a third leg, so the sandblaster doesn't have to lay on the ground. The legs are made of some perforated angle stock scraps I had.

The handle will make it easier to wheel around. I found the perfect thing in my junk pile, a lug wrench that doesn't fit any of our cars. good shape, about the right length (I'd have preferred a bit longer).

Next is the plumbing for the air and sand. It will be a little while though, because I'll be using the old galvanized water pipe and fittings that I'm currently taking out of the house. (We're re-piping in copper).

When I'm done I'll post a parts list in case anyone out there wants to make one of their own.
