I've been asked by many members about my blast cabinet.
Here are Scrapart's Questions.
How did you do the door seal and what did you use for the seal ?
What is the need for the vent on top?
How big is your viewing areas ?
What are you using for latches?
Gloves and how did you seal them?
Why does the sand flow to the center of the bottom?
How does the pickup work and why couldn't one just lay the hose on the bottom with a screen?
How did you seal the incoming lines ?
First off, make sure your tank is free of oil!!!!!!!!!
Mine was old n rusty. If your using a more recent one, have it steam cleaned first. Or you may end up in orbit.
In order to be able to seal the doors. I first cut the end caps off the tank leaving about an inch or so from the ends and then welded in a 0ne inch flange, both on the the doors and the tank. Using 1/8'' x 1.'' flat bar.
The seal itself is weather striping from the hardware store.
The hinges came some old doors and are welded in place with a gap for the weather striping.
I used lunchbox type latches from Spae-Naur. Hardware stores probably have them.
One thing I would change is to put a seal across the middle of the door instead of a deflector plate to keep the sand from getting in that part of the blaster.
I use a noisy shop vac to clear the finer particles out so you can see. I built this outlet with only the bottom open to try to only remove the finer stuff.
That's why you need an air inlet as far from the outlet as possible
A cyclone separator would be the best. Maybe some other member has made one and could show us how it's done?
The windows are 9'' X 24'' . I made some frames out of 3/4'' X 3/4'' X 1/8'' angle iron and made a matching opening in the tank. Then welded them in.
There is a thin weather strip between the glass and frame. The windows are held in place with 1/2'' square bar that has been drilled for 10/32 screws that thread in the frame.
I used regular light sockets and bx wire for lighting. Used 16G. sheet to make the lighting boxes and made some caps out of Alu. to house the switch and wiring on top.
I got the gloves and blast gun from the local automotive shop. I think the gun is a King brand.
To hold the gloves in place I made holes and welded in a ring or flange to be able to slip the glove over and tie it in with a hose clamp.
To be able to have the sand flow to the collection tube. I cut the bottom of the tank off and replaced it with a cone.
I built the collector with a 2 1/2 pipe ****** and cap to be able to remove it for maintenance and used a 3/4'' tube for the pickup.
In order for the siphon to work, there is a 3/ 16'' hole drilled ahead of where the hose ends inside the tube. Works just as a paint gun would.
Finally, The holes for the lines are really tight to the size of the hoses and make there own seal.
Hope this answers most of your questions.
