Introduction: DIY $5.00 Sandblaster

I have some rust on my driveway and some old rusty tools I got from my grandfather years ago.

I have been looking at sand and soda blasters for about 6 months. They are either inexpensive and cheap or very well made and expensive!

So I decided lets just make one.

Step 1: Get Crap

Go get some crap at Harbor Freight. This air gun kit ran $4.99.

Now find a bottle in the trash.

Step 2: Say "Hi" to the Cat

This optional but important step may be the difference between you succeeding or failing.

Step 3: Cut the Neck

Remove the locking neck for the cap.

Step 4: Drill

Grab a 3/16" bit and drill the neck just under the cap.

Step 5: Test Fit

Push the air rod in. It should be very snug!

Step 6: Mark

Mark the bottom of the air tube. Spin the tube around so you can hold the handle while you file.

Step 7: File

File a hole through the tube to let your media in. When you're done spin the tube back so the opening is at the bottom.

Step 8: Fit

Get the tube back into the hole.

Step 9: Seal

Not looking for the glue to actually stick here.

Just looking to prevent the hole from opening up too much while under pressure.

Step 10: Test Blast

Put your Saftey goggles and gloves on and give it a good blast. I shot at the rust on the drive way and removed a spot (the white part) in just a few seconds.

I will give you an update on the driveway once I have time to do some actual blasting on it.

Step 11: Real Deal

An old set of needle nose (rusty as hell...)

Step 12: Blast Away

Clean as a whistle!

Step 13: Extra Step

Because everyone keeps asking this is my air compressor a California Air Tools 10020c running at about 40 PSI for blasting.

I also use 20/40 crushed walnut for my media.

For PPE I use gloves, a P-100 respirator, long sleeves and a face shield. No excuses! Do not mess with your Safety!

Question 2 months ago on Step 13

So far...it hasn't worked. I'm still working out the kinks.

I decided to use playground sand. First mistake was having it be a bit damp. Second mistake was not sifting it for larger chunks.

After sorting those two issues....nothing. I'm not sure what I'm doing wrong. The bottle pressurizes, and very little, if any, air makes it out the nozzle.

How large of an opening needs to be cut in the tube?

Damp playground sand will not work. Air pressure has a positive force to the handle of the gun and only releases when the trigger is pulled. Your bottle shouldn't be pressurizing; air pressure is entering and exiting the nozzle, gravity feeds the blasting material into the cut slot of the nozzle, blasting material exits nozzle.

If your bottle is pressurizing, your nozzle is clogged.

in 1975 a Diesel mechanic show me an engine overhaul and that was one of the things he did - the less force you use the better preserved the items are

This is a very crucial step in this process. Of course if you have dogs make sure you say hello to them as you would a cat. Yes.

Very clever. I think I'll build a version and keep it in my sandblast cabinet for specialty work.

Everyone here making this instructable should understand that the P-100 filter mask is A MUST! If you use beach sand, play sand, ANY KIND OF SAND! understand that you are risking getting silicosis. Breathing the vaporized sand from blasting can and will kill you slowly and painfully after it sets in months or years later and there is NO CURE!

Also note that using sand specially made for sand blasting has a greatly reduced silicosis risk. And remember that this device has no ceramic tip so it has a limited number of uses before the sand sand blasts the air tip into oblivion.

I was wrong about being able to buy a complete sand blasting kit for $29. I discovered that when went to Amazon just now to buy it. $29 does NOT include the compressor. As far as the kits NOT INCLUDING COMPRESSORS are concerned, the cheapest one I could find was $11.95, and there were nine less than $19.00. The compresors I found were not that cheap. There was one for $13.95, but the next highest one was $19.95, and they went up from there. So, it looks like I won't be buying a sand blaster and compressor to clean the surface of my concrete driveway. I'll have to stick with the power drill and circular sandpaper discs I have been using.
