Making a SandBlasting Can and a Frisbee
Sandblasting cabinets. They are
either too small or too expensive. Most of them are just glorified
metal boxes with a pane of glass and a couple of holes for arms. I priced
a few in the size I was looking for and they were all way too much money
IMHO. So I decided to make my own.
The GOAL: Make a cabinet big enough to sandblast a dual snorkel 83-85 Mustang/Capri air cleaner (disassembled of course).
The PROBLEM: Being round and rather large, the air cleaner for a carbed (or CFI) Mustang/Capri just doesn't fit into the standard $50-$100 cubed sandblasting cabinets. There just isn't enough room (at least by my measurements). "Enough Room" includes the ability to fit the part in the cabinet AND maneuver it.
The SOLUTION: Simple! Molest a perfectly good big ass GARBAGE CAN!
Total Cost: $68.29 + Tax
The first spot to tackle is the lid.
This is going to be the majority of the project. Take a piece of
cardboard and cut it the size of the Lexan (18"x24"). Then start
trimming it to fit inside the center of the garbage can like so. Don't
trim it so it fits in the center TOO tightly.
|Use this cardboard pattern to
cut out your Lexan.
Tools Used: Dremel with cutting wheel. (Tried a jig saw and it sucked. Dremels RULE!)
|OK, now mark out your opening
in the lid. Screw a sheet metal screw in the center of the lid.
The lid will have a small dimple conveniently located in the center.
Tie a string to it and using one of the large 1.25" washers as a guide, mark
out where the opening will be.
Tools Used: Sheet Metal Screw, String, Pen/Pencil
Cut out the opening. The lexan will be bolted to
the lip that was left in the center area.
|Place the lexan on the lid
and drill 6 holes for the wing nut bolts. I just more or less laid out 6
of the LARGE washers until they looked equidistant around the cover and then
drilled my holes and bolted the wing nuts and
wing nut bolts with the large
washers on either side. I would recommend REMOVING the protective film
from the lexan. It makes it easier to see if you are choosing a hole too
close to the edge of the lid.
Tools Used: Drill and I think 3/16" bit.
|Mount the flanges. Again I just
eyeballed the placement of these. You can get a good idea of the
positioning based on the garbage can's handle in the pictures. Drill and
bolt up the flanges with the 2" bolts, washers on both sides and 1/4" nuts.
Tools Used: Drill and 3/16" bit.
|Cut the holes in the can for
your arms. Its really easy when the flanges are bolted up. The can
will flatten out a bit from having these bolted like this.
The flanges are flat and the can is not. Its not a problem.
The top will fit just fine.
NOTE: The flanges were also going to have some cloth or plastic sandwiched between them to restrict any blow back of media. However I skipped that step and therefore technically the flanges are not really needed...they COULD be skipped....BUT they add ALOT of stability to the holes and you won't chafe or cut your arms on the thin wall of the garbage can.
Tools Used: Sharp Knife
|Cut the grate to fit. I
was careful and trimmed it only enough to go down about 1 foot or so before the
bottom of the can. It wedged in nicely.
Tools Used: Hack Saw and SHARP Wire Cutters
|VELCRO! Find a good spot for the
light and Velcro it on. I put the soft stuff (loops) on the light.
Tools Used: Scissors
|TAPE! I took some clear packing tape and carefully covered the underside of the Plexiglas then rebolted it on the cover.||Sorry No Pic. :-(|
|Now to test it! I bought a crappy $20 siphon sandblast kit. DO NOT FORGET A RESPIRATOR!|
Things worked out really well. The only complaints are that a little media gets out through the hand openings. I had thought about that before I started and was going to try and sandwich in something between the flanges to make that area tighter. I will probably have my wife sew me something with an elastic band in it to stretch around my arms.
The positioning of the arm holes was actually surprisingly good. Sometimes you have to shift side to side to give one arm or another a bit more length to grab something but I was expecting a lot worse.
Another plus is that the capacity of the garbage can was MORE than enough for an air cleaner body (see picture). As you can see there is room for the air cleaner, the gun and enough room left over to maneuver.
The garbage can is VERY rugged as well. Hitting it with the sandblaster doesn't harm it at all.
Oh yeah, almost forgot. You should have a home made Frisbee left over. It flies well and looks cool if you leave the screw and the string in it!
