I think you are looking for 'abrasive blasting' rather than 'shot blasting'?

 

Sorta similar processes but for quite different outcomes!

 

Sot blasting is sometimes used for reducing surface raisers and the likelyhood of cracking, where as abrasive blasting is usually used for cleaning stuff up, especially when rusted.

If it's rust you'd like to clean up, along with paint, Garnet is good, but go easy.

 

If it's just paint you want to take off, Soda is excellent.

 

I don't do my own stuff. I have it all Soda Blasted first, then ONLY what's needed were there's rust (or in the case of bodies, filler), I have these areas spot basted with garnet.

Thanks im looking to go through paint and the odd bit of rust on the wheels never intended to use it for the body shell just on small parts that are hard to get to with wire brush and wire wheels. And to make life easier :)

I have just bought a small cabinet and have some aluminium oxide grit. It works fine but if the garnet is better will try it next time I get some

At work we use aluminium oxide on everything. Brings stuff up a treat, but be careful on weaker/more delicate aluminium parts and especially brass as it will just eat them away if you're not careful. Steel and cast aluminium are normally fine, just try and keep the distance between the nozzle and part as much as is practical when blasting the softer parts.

We also have a vapour blaster which we use on mostly aluminium or brass parts, which I believe has nylon bead but I may be wrong. The vapour blaster leaves an unbelievably uniform finish on brass parts, and also does a nice job of aluminium after being previously cleaned/sand blasted.

Edit: I also read somewhere that you have to be careful with the way you dispose of the used aluminium oxide.. but I'm not sure why as I haven't looked into it.

Let us know how you get on, as mentioned in your thread about the new compressor you have.. mine is of a similar spec, HP and CFM wise, so I'm interested in how well it performs at blasting. If it works well then I may build up an enclosure myself.

Air required is down to nozzle size but blasting is air hungry, I have a Clarke industrial 3hp that keeps up ok, make sure you have good water traps as well.

i have used aluminium oxide in 2 different grit grades, fine woks well to make things have a good clean finish , carb body alloy parts. etc  where the course is better at removing the bulk of rust an paint.

 

you will find it hard to remove powder coat, it does take a lot to remove. 

 

i have also used normal paving sand from wickes, its cheap for a bag, http://www.wickes.co...r-Bag/p/220201.

if its damp at all, i put it in a old roasting tray and put it in the oven to dry it out before putting it in the blast cabinet, 

 

i also connect a hoover to the filter side ( breather) of the cabinet, it helps to remove the fine dust in the air in the cabinet , which helps you see what your doing. 

 

also stick these to the inside of your glass, they will get hit by the grit and start to make them go frosted over time,  but its easier to change them than the glass. 

http://www.ebay.co.u...s-/221857710075

 

its just a example link, you be able to find them cheaper, as it just a thin film , double sided taped to the inside of your glass.
