Sandblasting Cabinet

Project:
To build a sandblasting cabinet that can be folded back into a work bench for storage

Difficulty Level (Easy, Medium, Hard, Insane):
Hard

Process:
Melanie finally booted me out of the house and told me to go have some fun in the shop so I decided that I was going to start the huge restoration project of my 1949 Ducati Cucciolo. I took it out, put it on the bench and envisioned taking it apart when I realized that as soon as I started, I'd have to be able to blast the parts. So I decided that I better build that blasting cabinet I've been putting off for over a year now (I bought a sand blaster in November 2011 when we were down in the states but I never really had the chance to use it because of the mess it would have created).

Whereas sandblasting cabinets are easy to find and are fairly reasonable, I'd have to get one large enough to do my tires and fenders so it would cost at least $400 bucks at princess auto. Whereas the price would be somewhat justifiable, I would have just absolutely no place to store it for the rest of the 364 days I wouldn't use it in the year so I figured if I could custom build one that collapses back into my workbench I could have the cake and eat it too.

Pictures:


After I had unscrewed the 3/4" sheet of OSB which was/is my bench surfase
Cutting the 2x8 boards
After I built the collection box underneath
The vacuum hose that will eliminate the dust
I had to weld the 8" strips of iron mesh to form a 30" x 36" wide base
Supporting the base with some 1"x1"x1/8" angle iron
Using my ramset tool I shot some anchors into the frame of the work bench to hold the vertical piece of the cabinet
I had to drill and tap the support brackets so I could screw down the hinges for the sides
The sides are folded down, the back (and rear half of the top) are folded up
After installing a 24" fluorescent light
I had to do some math to calculate the front, the angle and the front half of the top so they'd add up to 30" so that when I fold it all down it would be the same as the depth of the work bench
After the hinges were installed and the basic frame was put up
Cutting out the area for the looking port and for where the arms go in
I re-inserted the part I cut out at the front and cut two holes for the arms
I stapled the sand blasting gloves to a larger piece that will go in the front while the cabinet is assembled
It's coming together. The gloves are in.
Finished! Now, on to trying it out on something
A dull, old, rusty ax I had lying around
After it was blasted. This only took about 2 or 3 minutes and two cups of blasting media
A couple of minutes of sanding it with an orbital sander and it's as good as new
