Make Your Own Sandblaster and How to Use It





Introduction: Make Your Own Sandblaster and How to Use It

Need to make your blue jeans more stylish? Want a gorgeous frosty finish on metals or glass? Want to paint to stick to something? Mr. Sandblaster is your answer! Make one today - it's really easy! Here's how:

The sandblaster in action, frosting a test-strip of copper for one of Tetranitrate's secret projects.

Step 1: Materials

Sand gets everywhere, unless you do this all inside an enclosed box.

Sand got in my nose, between my teeth, ears, and despite the goggles, my eyes. When this was done, I looked sparkly from all the garnet sand dust on my face. Consider wearing a bandanna, especially if you have any respiratory issues. Actually, you really want to wear a respirator, to avoid silicosis. Use goggles if you have them. Swimming goggles (that seal over your eyes) or a snorkel might work best.

To construct the sandblaster, attach the hose to the air gun, and drop the other end into a bucket of garnet sand or other abrasive. Any even-sized abrasive should work - we grabbed this out of a pile of abrasive meant for the water jet.

Once everything is assembled, proceed to sandblast!

My jeans are indeed whiter.

Step 2: Making the Sandblaster

The setup is a normal air gun, with a hose at a second attachment. This sucks in sand at a constant rate, via Bernoulli's Principle, like an aspiration setup in a chemistry class.

Find a bucket of sand for the hose to rest in. Find some good method to keep the hose submerged in sand, like duct-taping the hose to the side of the bucket so that it's always pointed downwards.

We just tipped the bucket so the sand was in a huge pile on one side, and stuck the hose into that. Even so, every now and then the hose stops sucking sand, which sucks.

Hook the gun up to any compressor hose.

Step 3: Sandblasting

See what materials work!

Tetranitrate draws a smiley face (and subsequently, a frowny face) on his pants:

I sandblasted my jeans because I am struck by what a ripoff it is to pay $60 for sandblasted jeans.

The tshirt I sandblasted didn't change colors, but it felt thinner in that patch.

Later I sandblasted "DIY" onto the back of my left pant-leg. The intersection at the forks of the "Y" actually burnt/blasted through, giving it that rough, well-worn look. Want ripped jeans? Just sandblast them a little more.

Otherwise, metals are great, so is glass (especially glass - you can mask and sandblast wine glasses, or just give a frosty finish to anything you're working on.)

Industrially, sandblasting is used to evenly rough a surface before it is painted.

Also, don't do what I did! Take off your jeans if you want to sandblast them - my leg felt burnt for a few hours after blasting them.

(all the same, it was a blast - I didn't take them off because this was impromptu and I couldn't, y'know, take them off there in public and all..)

    Did u use a regular compressor? Or an electric tire compressor? Gr8 job, just wondering if I could use a small electric compressor.

    I wonder how many people have just dumped the hose in a bucket of sand as in the image and wonder why it isn't working

    I have a pressure washer with a soaper attachment, could I feasibly put garnet sand in the attachment and use it for sandblasting? or would it just f**k up the washer?

    That would definitely work. I have one of these at home and it works great. I sand blast on Saturday and wash the car on Sunday.

    I would like to say "Good 'structable' : but... There and mentions of safety and goggles, respirators etc. But stop being foolish; you really need to know that sand blasting is bad for your health. If you use silica, silicosissilicosis and fibrosisfibrosis are possible results. Even cleaning yourself off or others withcompressor air compressor air is NEVER a good idea. Oil lubricated compressors have the added hazard of oil mist. A full set of rules can be found in the link. Then you must also consider the material being removed b the blasting.

    The title is a bit misleading; it says "Make your own sand blaster, And how to use it" Clearly you did not make your sandblaster, it looks like it came from Harbour Freight. You used it, but not safely, and could possibly mislead others. Thanks to ironsmiter for the tip on baking soda, and ditto wasp's sentiments.

    chill its not like any one would use this every day the exposure wouldent be enough every one would just use it for one quik project and yes it is hiughly recomended to wear a reperator at the least a dust mask and googles are near manditory cuz if one high speed peice of sand hits you eye it could scratch your cornea and blur ur sight for quite a while

    You can get enough silica in one exposure to cause lung scaring five years later. There is no cure for silicosis. Do Not Use SAND. There are other abrasives out there. Period.

    Chill,its not like anyone would use this every day,the exposure wouldn't be enough.Everyone would just use it for one quick project,and yes,it is highly recommended to wear a respirator,or at the least, a dust mask.Goggles are near mandatory because if one high speed piece of sand hits your eye,it could scratch your cornea and blur your sight for quite a while.
