Sandblasting Heavy Rust Away

Good work buddy

Also thanks alot for your help with the other viewers!
Cheers again

thanks but the problem is that i live in mexico.someone else; what equipment i need?

simple rule is any grit below 0.8mm works. the grit in this video is copperslag which is like a black sand. using silica sand for sandblasting is dangerous to health if breathed in. mortar sand is likely to contain silica, and also little stones larger than 0.8mm so would only work is sieved, and health consideration come into play. there are various expendable grits available on the market which are low in free silica (for example copperslag, garnet, SC sand substitute) - hope this helps

what's abrasive you use?. can it be simply mortar sand?

that's right... If you remove the rust, it looks/is basically like new underneath. If you don't seal/paint it right away though, it will start to get rusty again.

Is that like black beauty, if you know what that is?

holy S**t i didnt know that you could do that. you mean that there is actually good metal underneath rusty objects???

if you look at the video, you can see dark dust from time to time, there is not a big cloud of dust because the nozzle is fairly small, but it is there, the grit used is coppeslag which is a black grit.

Where's the dust?

wasn't really paying attention to the gun sorry about that.

It is so good it does look like it does'nt it? but as the author of the video, I can guarantee that this is NOT silver paint, - what is being spryed here is grit/sand at high pressure which removes the rust that yu see on the piece leaving a clean bright finish which is what steel looks like when it is blasted.

just a correction to fishhunter's comment, what is described in your posting is how a suction system workds (the type which looks a bit like a paint spray gun) the video is a pressure system where tha air & grit are inside an airtight pot and the lot pressurised and sprayed through hose & nozzle - this is a much more efficient use of pressure available & is therefore much more powerfull for the same amount of pressure as a suction system.

to add to what you said what it does is the high pressure from the air compressor goes through a venturi which makes low atmospheric pressure and S**ks the sand through the hose and combines with the air in the blasting gun. There are many different types of media that you can use to shoot out the gun.

Am I the only one who thinks this looks too much like silver spray paint to be real...???

Hey mate, I've been thinking about getting a sandblaster setup for a while now, 2.5hp, 8.2CFM, 115psi max, belt driven. Would that be suited to cleaning up car parts? Like engine blocks, cast iron manifolds etc. What would be the best media for such things? Thanks for your help in advance!

My Dad's a Blaster. And i can give you a bit. Its a high pressure hose which shoots Sand or ( Grit) Garnit, And Metal at very high PSI. Its Fairly easy and im hoping to get into the buisnes soon. Hope that helped.

Excuse me for my ignorance on the subject but I don´t understand that about "sand" blasting, what kind of sand does this use, can you give me substantial information? Thanx!

well, if you've got access to nearly unlimited supplies of sand...

haha i could do this all day. good sense of satisfaction

d(-_-)b

It works so well it almost looks like your painitng it silver...FANTASTIC!!!

Nicely done. Just a little smile appeared seeing the vid's title 'heavy rust' :-)

When i have a good rusty piece to blast i shall show what is heavy rust ;-))

Hey take care when u have more vids please show them, i find it very interesting!

Sorry for late reply - I just saw your comment!, this demo is done @80psi with a 3HP compessor (15cfm)- the blast media used he was fine copperslag.

man thats a nice setup.

looks like a quality product....what kind of pressure do you have to use with it, what kind of blasting media?

nice job
