Homemade Shot/Grit Blasting Cabinet

Step 5 Conclusion

Put your blast gun in the cabinet, put the grit and air hoses through the hole, clip the lid on and you are ready to go. The cabinet will need to be periodically emptied of grit, to do this simply take the lid off, take the grid out and pour the grit back in to its storage container.

I hope this has been of help to some of you, if you have any questions please feel free to ask in comments or message me with them. This is my first Instructable so constructive criticism will be gratefully received.

How about an improvement for this? Fix a large plastic funnel in the base of the box. The blasting medium could fall into the funnel and this in turn be collected in a pot. Obviously you'd need to have the cabinet raised up but this would eliminate the problem of the grit layer being too shallow to be reused straight out of the box.

Good 'ible', well done.

wondering what you use for grit, standard sand or metal?

Depending on what you are blasting..for metal parts that you do not want to change the structure of or pit it, I suggest walnut shell for it will not damage the metal, you can even blast internal engine parts such as pistons, cranks etcetera..Heres another clue..Instead of paying high prices for it, any major pet store that sells pet supplies sell ground walnut shell for lizard bedding.The grit is too large for smaller spot blasters, but A food processor will grind it on down further for you.

I'm using iron sil, which is sold as a fine blasting powder on ebay.

great idea. i plan to make one soon. just wondering, how do you vent the air pressure that builds up?

The little shop vacs that are 12 volt dc would be great for this small blaster

Could you have the source of your grit be the bottom of the container so it continuously uses it? Then just change that periodically. Would it get too contaminated that way? Obviously this idea would work better with a different kind of container.

Hi, if you read through previous comments that idea was explored in depth. basic answer is in this case no, the layer would be too shallow, you'd have to move the pickup hose around all the time. In a taller box, yes good idea.

I like it. You could use a leg from an old pair of jeans and duct tape it to a glove and the box to keep dust low.

if any one is thinking of making one, make the window easily removable as even glass in a small low powered grit blaster gets blaseded indirectly and fogs up, all that said, nice build well done
