Sandblasting gun

Blasting gun to replace standard gun on table top blasting cabinet. I believe it would also fit the standard floor type Harbour Freight Chinese cabinet.

A foot pedal is recommended although i just connected and disconnected the air hose in use.

The blasting gun uses the same ceramic nozzle as the standard gun. The air nozzle I made out of a piece of 70mm long M10 threaded rod with a hole drilled through. The diameter of the air hole should be adjusted according to compressor size. I drilled mine at 3.5mm and my 5.5Hp compressor can hardly keep up. A 2-2.5mm nozzle would likely be suitable.
Tip of the air nozzle is placed about 15mm inside the gun from the tip. I would recommend to test different positions and see what works best for you. Same applies to air nozzle diameter.
The M10 thread is cut into the gun using a tap.

Hose connection is 12mm
