Which sandblaster?

A blasting cabinet is only as powerful as the air compressor you are using with it. The one your looking at is very small and you'll be limited to what you can put inside. Once you buy a blasting cabinet you will find MANY uses for it. When it comes to the cabinet bigger is better. Harbor freight has a really good one for the price and is big enough for most home projects.

This cabinet is garbage. I have the same model and can't blast anything without getting silicon all over the place. It makes a huge mess and costs a bundle in lost material.

I wanna get a sandblaster.. which one is the best, least expensive?

i was looking at this one:http://www.ebay.com/itm/25-Gal-Benc...595&pid=100015&prg=1006&rk=1&sd=270739041970&

Just want one to take rust off metal parts.. dont need nothing big, just powerful enough to take off the rust. Im not familair with these, can anyone help me out?
 
I have the one from harbor freight that posted above. Whats important is that you have a way for the pressurized air to get out or it will find its own way out with the media. On mine there is a port at the top left. I Drilled holes in the cap and put a very fine mesh to let the air out but catch the media. Also have a good air compressor is mandatory. otherwise you will be blasting for 5 min and waiting 15 min for the pressure to build back up which is super annoying. Also check out soda and dry ice blasting.
 
The HF model has a dust collection port on the back right that easily connects to a shop vac to keep the inside clear enough to see.
 
By the way, this method is actually safer than standard media blasting and most people only have a light duty compressor which is perfect for this style kit. I keep the container when it is empty and just order more soda from harbor frieght. Did the whole suspension system on my 240Z like this before sending the parts to teh powder coater.

That cabinet is fine for home use, but yes it's messy as hell (they ALL are) and you need a lot of accessories. I documented my setup in another thread.

Basically you need to hookup a shopvac to remove the dust. You also need a cyclone dust separator or else the filter will clog in minutes. You need a long ass hose for the moisture trap to be effective. Finally you either need a massive compressor or to modify the setup as described with a pressure blasting tank.

It's a useful tool, but in hindsight I'd recommend finding a local shop and getting them do the blasting and painting for you.

CFM is what you need to run a sand blaster... a small cabinet for small parts a 20 gallon 5cfm upright would suffice for a hobbyist.

Have you heard of electrolytic rust removal? It works really well.

It works very well, and it is simple to do. That link i posted to Easton is cheap and it works well to remove paint and rust in just a few seconds.

I have the one from Harbor freight. Its got a decent size cabinet and I hook my shop vac up to the side to pull out the dust and air. Only bad thing is you need to watch the media type. The metal on the cabinet is pretty thin.

The harbor freight cabinet is rated as 9.5 cfm @ 90 psi and they're not kidding. I have a 20 gallon craftsman compressor like you describe. As soon as you pull the trigger the pressure starts dropping, and the siphon gun won't even pick up media once you get much below 90 psi.

It really wasn't usable for me until I modified my setup.
