I like that one. I seem to have outgrown mine. which is a pretty heavy duty unit, has a self contained vacuum on back, with a Mack truck sized air filter... IDK the brand but definitely not home made.... problem might be garage space for a cabinet that will swallow my recent blasting projects easier, that I don't want to do outside with the pressure pot.
a 15" car rim will barely fit, (cabinet plenty tall, its the other 2 dimensions that are lacking) had a Slant Six intake manifold in there 2 days ago/ and the head off the same engine yesterday, have to put that in diagonal and had to pull it out and flip it to get the last 2 chambers.....
(off topic comment) gonna try my hand at a home porting job/ or at least the start of one before I send the head in for the "nomal" valve job stuff.... material needed to come out easier to see while blasted clean.....
