Been modifying a small benchtop blast cabinet.

[woodchucker]

I did some bead blasting of some parts. I had to braze up a Moto Guzzi brake pedal for someone. To restore the look after filing and sanding, I bead blasted it to see what I liked and didn't with the cabinet. I knew going in what I didn't like, and confirmed it.
Too much space at the bottom for glass beads or any abrasive to hide from the pickup. So adding some slope to the sides, and going to shorten the hose and use a copper pickup tube, with and added air pickup. Going to move the air inlet and eventually replace the gun. I would rather use a foot pedal. Might go with a fixed gun and just move the part..

Started with a cardboard template as its much easier to adjust things that way.

Then roughed out the panels from my old furnace panels. Used light scores to help bend since these are heavy gauge. New stuff is much lighter than the old.

Bending was quite easy using two pieces of square stock.


Gotta cut off the ears on the top. Going to glue these in using liquid nails as it should seal it nicely.

I think I'll need a vibrator to shake the abrasive to the bottom.

I added a vibrator to my blast cabinet, it helped a lot.

what kind did you add? I've been thinking of taking a small R/C 400 motor and adding a weight to the shaft to see how well it works.
I looked at the skat, but it's very pricey for what it is.

@Eddyde does that just vibrate the media so that it falls to the bottom better?

what's the black box? It doesn't appear to have an adjustable speed.

Mainly, it vibrates the media so it feeds better into the pick-up tube. I almost never got a stall or clog once I installed it.

I don't recall if my vibrator has that box but it isn't variable speed. I will eventually rig it with a foot pedal and a solenoid valve so it will vibrate only when blasting. I have the cabinet mothballed right now, awaiting some renovations I need to do to make more space.

That's very similar to what I did to one of my cabinets. I put a drain in the bottom and run a siphon type pickup with adjustable air bleed. Plenty of you tube videos on the mods you can do.

I went from a foot pedal to a lever that I can push with my leg or knee. Much easier for long sessions if you have any ankle issues. Set it to a height that is comfortable for you.

I should note that since I picked up a bigger cabinet, I'm putting together a similar setup. The table top found a new home. Yes, before I got the new one modded. Mistake.

I also added a vibrator to my blast cabinet. It has a variable speed, but I leave it set at about 3/4. It is kind of loud but has solved the problem of occasional drop outs.

What kind is yours?
