2. Skill/saber saw
3. Hole saw....for the dia of your media pick-up hose
4. Rivet gun
5. Caulking gun
6. welder ( to weld plates at bottom of legs for caster to attach to)
& also you will need a porta band or hacksaw I didn't mention this in my
original post.
First I removed all the refrigeration parts from the freezer.
Then I made the legs for it.(length will depend on how tall user is) Two
legs on one end are 1/2 inch taller than the other two at the other end...
this is to make it slant downhill to one side for media to return to drain
hole. I also connected the legs together with an "X" brace to eliminate it
from shaking. This brace runs diagonally from front leg to back leg of
opposite corner and welded it on, and tack welded it in the center where the
other half of "X" brace crosses.( you can make it run all the way around and
make a shelf on it if you wanted to.
I welded a plate inside the bottom of the angle iron for the casters to
attach to bottom of legs. Caster are off a shopping cart. Grocery store gave
me an old one in the trash out back of the store.
I then drilled the 1"x1" wide angle iron for rivets in the drill press.
(two hole per angle) and then took a hand drill and drill holes for them to
be riveted into place inside the freezer 4 inches off the bottom along the
sides about every foot apart...the angles them self are about 6" long,
these hold the grate for parts to lay on while blasting.
I then mounted a engraver ( what you etch you name on tools ect. with in the
bottom to vibrate the media to the funnel.
I then put a funnel onto the bottom of the freezer for the media to fall
back into a 5 gallon bucket that I mounted to the leg underneath at the
bottom.
To mount the funnel I just took two strips of sheet metal and made tabs to
attach to the funnel with a pop rivet and then attached the tab to the
bottom of the freezer with rivets also so the funnel was up against the
bottom tight, and used the drain hole for defrosting that was already in the
bottom of the freezer .
I got my gloves and glove retain rings from TP tools. You can order them on
the Internet at
http://www.tptools.com . They are 7 1/4 " outside dia.
holes for the rings to fit into the cabinet. I just used them for a pattern
,drew a circle around them and then drill a hole in the middle of that
circle big enough for my saber saw blade to fit into and cut the circle out
and then mounted the gloves with the rings for them.
I then mounted 2 flood light fixtures inside for light ( these ole eyes
need as much light as I can put in it)..LOL. I put a receptacle box on the
outside for the light switch .
I then took a hole saw ( the dia. of the media supply hose to your blast
nozzle) and drill a hole just below the right glove hole just above the
grate inside.
Now I marked out for the school bus window . Make the whole 1 inch smaller
than the window on all side. Drill hole big enough for saber saw blade and
then cut it out.
Now I made angle iron clips to hold the window into place against the side
of freezer. I had to take two pieces and put them together so the lapped
over on another to make a lip to go against the freezer and also to go out
and around the window. I am sure you can figure it out just play with two
short pieces of angle iron a inch long. I then welded them together when I
got them to the thickness as the window and then drill holes in them to
attach them to the cabinet to hold the window into place. I used self
tapping screws so I could replace the window if need be. I also silicone
caulked the edge of the opening around the hole for the window before
putting it on.
I cut a whole for a piece of PVC pipe to go into so my dust collector can
be attached on to it
TA DA!!!!!!!!!!! you now have a "Cheap" well built " Professional Looking "
Blast Cabinet.
If you need any more info just drop me a line and I'd be more than willing
to help if I can.....................Good Luck Fred
