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!
3 People Made This Project!
We have a be nice policy.
Please be positive and constructive.
If points/Open-Close mechanisms or Screws stucks due to Rusting lie item in Brake fluid and it'll eat away the Rust with out too much damage
Why does the hole have to be in the bottom of the tube? Thinking about it, wouldn't you want it on the top so that gravity helps the media enter the tube?
Can I substitute a a dog for step 2?
Where do you get the walnut media?
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
