How to make a simple sandblaster

I tried to make a sandblaster with an air duster and a compact compressor.
【Tool】
・compact compressor

・Air duster

・putty

・Homemade drilling machine

・grinder


Sandblasting was successful, but found some issues.

【problem】
Insufficient compressor output for continuous operation.
Worn air duster nozzles.
Recovery of alumina is difficult because there is no alumina recovery cabinet.
