dont you need a regulator for the air going into tank that holds the sand?

@shortyjk95 No just as long as the pressure is the same on top as the bottom the sand well flow like a hour glass smooth and steady.

Hello, nice vid! I made my own sandblaster as well but was wondering, what should the internal diameter of the hose be that goes to the nozzle? I can blast for a few seconds but then pressure drops and no more sand comes out. The internal diameter of the hose i used is 14mm and the nozzle 3mm but I think the 14mm are too much. Any suggestions? Thanks.

@motorcycleengineer Hi. It sounds like a air supply problem what size is the supply line from the air compressor. If you look at the air hose ends and fitting that is were the most of the restriction is usually. My hose on the air and sand end is 1/2'' ID. or looks about 12.5mm ID. I would think that 14mm would be just fine. My supply line is a littel to small but if you look at the ends of the hose some of the brass ends have a bigger openings than others plus don't use couplings either.Thanks

thanks for the reply. one more question. what did you use to drive out electrode?

@oldpacrat Hi again I used a small Allen wench that I cut off the 90 Deg. angel. Any high carbon steel punch should work fine . You could try and start it just with the hammer first but try not to enlarge it or it well crack the porcelain when you drive it the rest of the way. If it flattens out grind it down or you could grind it some first . They are a little had to get started I put mine in a vise to hold it. Sometimes I get a small chip at the J end of the plug but it well still work.

I like the spark plug idea.

@gildardo011 Hi there. I bought the hose at Farm&Feet in the Ag department it's 1/2" ID it works fine at 100psi but I wouldn't go over that . Not sure but regular air hose mite work Don't know if the smaller ID would hurt that much. Thanks alot . Had fun making it .

@oldpacrat Hi. The spark plug must be a old Champion J-11Y J12-yYJ14Y there the only only ones that I could drive out the electrode. I broke off the J of the plug and drove the electrode out from piston side moving to the plug wire side. Hope this helps :)

can't figure out how to get sparkplug apart. please help>

@plumcrazzzy Hi! Here is a photo with a sparkplug that I used for about 7 hours :)
