Si basically whats happening is the black stuff is so course and heavy it wont suck up the tube...right??? How is glass bead sizes graded??? Bigger the number the bigger the size of the beads???MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I think glass beads are rated/scaled like shotgun shot pretty much....so the more "O"s, the smaller they are....could be wrong though....the one thing about glass beads, is that they are slippery....so tend to flow better.....and since you have a cabinet, you can reuse, right ?....might be worth a try....but they aint cheap....I wanted to blast a 1962 Harley tank, went to get the beads, and it was like $30 for like a gallon container....I pay $7 for a 40 lb bag of the Black Diamond....

I have the HF cabinet too and use the cheap stuff from the farm store, it's called black something or other, might be diamond, I'll have to look. 5 HP compressor and 20 gallon tank. If you take out the screen in there (assuming your not needing it to support what your blasting) and put a long kitchen slotted spoon in the cabinet you can give a stir periodically. Sometimes the media doesn't want to fall all the way back down to the intake hose and a quick stir without having to open up the cabinet door saves time. I always have good results

So I am leaning at running over to HF and grabbing 25 LB sack of this...opinions??? Not so sure of the "ground glass" media.

The glass flows better, but costs a lot more....all depends on yer budget.....Ive used playsand (silica) and its VERY dangerous to your lungs (I have emphysema btw), well, IMO, if yer gonna use glass beads, even in a cabinet, make sure you have proper respiratory protection. That goes for ALL media btw....even though I dont use it using the Black Diamond....if yer a younger guy, please wear a proper respirator....dont matter with me anymore, I'm gonna be dead in 5-10 yrs anyway....

Theres a fitting for hooking a shop vac to which suctions all the dust up and the vac filters the air obviously so thats a good feature. I always wear a dust mask at a minimum if grinding and stuff thats thrown debris around.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

Get the black stuff and call it good. The glass stuff from HF, at least in my experience, breaks down to quick

If you are going to be painting the stuff after then glass bead is not that good as it leaves a smooth surface, nothing for the paint to bite into to, especially on aluminum.
Bead is fine for paint, corrosion removal on aluminum but then you need to follow with an abrasive which will ensure adhesion. I always follow with 80-120 grit aluminum oxide at about 60-80 psi, leaves a great surface for paint adhesion.
Glass grit is also a good cleaner, more aggressive than beads but will not leave as smooth a surface and is usually way cheaper. The coal slag, I used it once, is pretty aggressive for aluminum IMOP.
I have a 90 gallon compressor with a pretty good CFM delivery rate, I think your small compressor is gonna be worked pretty hard to feed the cabinet for an extended blasting time, small quick parts no problem, but cylinders or cases are gonna be hard on it. You will be working it so hard it will get very hot and you will end up with lots of moisture unless you have a really good separator/dryer.1978 Gs1085 compliments of Popy Yosh, Bandit 1200 wheels and front end, VM33 Smoothbores, Yosh exhaust, braced frame, ported polished head :cool:

40 bucks for a 180 normal store priced unit was a no brainer for sure. Im thinking it didnt work for him like this black stuff isnt working for me so he sold it. I will get the fine glass beads maybe next week and see what they do. Sucks the w2alnut shells up like noones business but they basically just bounce off and are doing nothing. Just not hard enough im guessing.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)
