Hello Guys. After a long time Im back with a new small project.
Its a mini sandblaster made out of scrap. Also I made a nozzle from a spark plug.

I love the sparkplug ceramic as a nozzle. Should it be a bit closer to where the sand meets the airstream? I feel like the abrasive is going to hit a lot of metal before it makes it to the sparkplug.
