Sandblasting rust off metal. Easy!!!

[commender27]

Can you do my wheel?

[mta415]

@adlingsmcr what media were you using in this vid?

[odlingsmcr]

@mta415  Aluminium oxide I think

[Veikra]

40psi in a pressure pot or 40psi on siphon? and what blasting media and size are you using ?

[odlingsmcr]

@Veikra In a pressure pot. Using a siphon would need about 80 - 110 psi. using aluminum oxide probably an 80 grade

[Veikra]

@odlingsmcr  I was wondering thank. Only my pressure pot gets fast results like this but since most use siphon in those large cabinet I thought it was one.

[GM572]

Sand blasting at 40 psi. Brutal!

[odlingsmcr]

@GM572 Its surprisingly gentle at 40psi. unless its ultra thin metal youre blasting you should have no problems.

[CaIlidus]

That is so fucking COOL!

Needel scaler?

[redghost105]

would dry ice blasting get rust off?

because i wouldnt want to damage the metal with sand hitting it and i wouldnt want sand to get inside my car(I have a 1969 camaro im restoring and its got alot of ruse on the top of the car and the 396 big block engine)

[mikehome]

@redghost105 Ive heard about this dry blasting business, but never seen it. From what I have been told it will remove all the rust but not damage the metal. I would just use soda for the block and top. It will wash off better.

[crazycardist]

can you show sandblasting a saxophone? that would be cool

[mikehome]

@crazycardist If you provide me with a sax then i will give it a blast.

[gun9834]

Tht would feel like magic on one's hands..... :-)

[jaggass]

when you sand blast does the grey finish stay on or is it just dust that washes off to show the bare metal?

[mikehome]

@jaggass The grey finish is the base metal. It will rust over if not treated.

wayofthemaster Is a great site, no I'm not spam

[KFCHambone]

I have a question please. Im going to sand blast my chevy novas underbody. Will the media that gets stuck in the nooks and crannies rust my car out faster?

[mikehome]

@KFCHambone If you use the wrong media ie metal based ones. then yes it will leave deposits in the nooks and crannies and cause rust. . Either use a soda blast company, or give it a proper blow out.

Indian Ocean Garnet Sands CO, located in Tuticorin, India produces one of the finest variety of abrasive sand in the world (ocean sand, washed and processed for different mesh sizes) - Yes, they do supply worldwide - Thanks for this wonderful video. Sure, sandblasting works better with metal rusts.

Pablito use a professional...

[Scourge1024]

I've heard of CO2 (dry ice) blasting as well as using baking soda. Also heard of using an alkaline dip if you want to do the whole car at once. But then you have to worry about coating all the newly exposed parts. E-coating is one method but I can't get that done locally.

[brewerfan1993]

Sand media.

[SendinK9]

Can anyone tell me which is best for blasting rust off metal just like in this video. I am restoring my Austin Healey and I will be blasting some of the parts (not the car body)

1. Glass beads?

2. Aluminum Oxide?

3. Or will just plain old silica sand do the trick.

I'm in a small town and can only find silica sand. If this isn't going to work, I will need to make a 2 hour trip to Seattle. Shipping cost to much $ just to ship sand etc.

[odlingsmcr]

Glass bead is best for polishing any ali parts eg manifolds etc... but people tend not to use glassbead on engine blocks and gearbox casings as it can cause havok if its not cleaned out properly.

odlingsmcr

Thanks for the useful info. Since I have posted I did some investigating locally around town and found our local blast company uses a product called Kleen Blast so I bought a 100 lb bag for 10 bucks... It is small bits of copper slag and when used it does not hurt the metal surfaces. It also has a wide range of surface applications and last 5 times longer then glass-bead or Alum Oxide. So far it has been working great and doesn't have the health risks the silica sand would have.

[odlingsmcr]

Aluminum oxide will clean off rust and paint etc but wont give the same shine glass bead will. great on small body parts. will also cause havok in engine parts, you will want a medium grade 60 - 80 would do.

things like brass and copper use glass bead at a low psi.

[odlingsmcr]

the user below is right Soda or plastic media is the best for cleaning engine parts because is leaves a good shine and wont damage the parent material. but mainly because it will simply wash away or burn off hence no damage to the engine parts.

Silica sand is a big no no, when it breaks up in to dust it can cause serious health risks such as Silicosis. I think in the UK it has been banned for certain applications.

Hope this helps

@odlingsmcr

I believe a (professional)mask or a fresh air respirator is required when using silica in the states. Even some of the iron oxide bags state, it might have a bit of silica in it.

[plotjr]

what do you suggest for cleaning engine block ? What media and PSI ?

[lainey500]

soda or plastic media as used on aircraft engine components.

[craigandrews88]

im doing that now and im using glass beads at 90 psi. its working perfectly, makes the aluminum block look like new. not too abrasive, but not to fine.

[Pepito0001001001]

Craigandrew, please could you tell me if the glass beads are reusable?and if so, how many times? I never work with it and seems to suit my needs. thnx

[craigandrews88]

well it depends on what your using it for. if theres oil on an engine then youll get clumps of oil in the beads and youll need to filter it out with a very good filter. i used fiberglass window screen but the clumps were so small they went through so something smaller than that. and after while the glass will just turn to powder and be no more good. i got about 3-4 reuses before it turned to powder. and if oil does get into the glass, the beads are so non abrasive that it will just clog the gun

[RottingBoard]

What are you using for primer. Rattle can? Small parts are a pain to mix a batch of car paint.

[KSOEM1]

With conventional home air compressor, the sandblasting time would only last 1 minute... They(the author) are using large air compressors and air tanks...

[odlingsmcr]

The comment above is right, A proper sandblasting cabinet, by that a mean one with a proper pressure pot on the bottom (cheap Snap on, sealy's and clark's dont have these) require a compressor which will kick out at least 25 CFM (Cubic Feet/Min) for continuous blasting. Any less than that and the blast time will be reduced to let the compressor re-charge.

A proper sandblaster is about 7 times faster than a cheap one, plus no dust problems or visibility issues.

[carlocardillo]

sand blasting is good but are there any advantages to it over shotblasting...

[SSchicago85]

What kind of media are you using? what PSI?

[odlingsmcr]

We used an Aluminim Oxide 80 (80 refers to the grade, ie grain size, 80 is a medium one) we blast a 40 PSI, any higher and the media becomes useless as it simply shatters when it hits the metal surface, this create dust and reduces the life span of the media and wont clean the item.
