In all fairness those parts weren't buried under a lot of rust... some were but others not. I see on the TS website they specify the Black Diamond for the syphon blaster and that's what I use.
If you notice in the
PICTURE of the carport, there is a kitchen trash can on a hand cart. I fill the blaster and that trash can with abrasive and when the blaster runs dry I just scoop abrasive from the trash can. With that arrangement I can get 3 loads of abrasive through my gun without stopping and that's all I can do in one day.
You will also notice a white box looking thing on top of the trash can. That is a simple sifter made from wood scraps and a window screen that fits on top of the trash can. When it comes time to clean up I sweep the abrasive into a dust pan and sift it through the screen and fill the blaster and can. Like I said, I'm recycling about 80% of my grit.
I have a Kobalt 60 gallon compressor (3.7 Running HP, 11.5 SCFM @ 90 PSI) and it does get a little down time as I work... it probably runs 70% of the time I'm blasting but I'm only running 80psi to take some strain off the compressor.
I've never used a pressurized blasting pot so I can't compare. I'm sure it has to be much more powerful than the syphon type but as you can see... considering the trouble free operation of the syphon, you're probably making more progress in the long run.
