Mediablasting at home

Anybody done it?

I'm looking at this:

http://www.eastwood.com/soda-blaster...t-w-media.html

I figure that it would make a big mess, so I was thinking about a big, shitty Wal-Mart tent and a respirator.

I would be a bit skeptical of their claim that 7CFM at 80 psi would do the job. I bought a similar rig from northern tool and our shop compressor was not up to the task. That said, if you have time and patience, you might be able to chip away at it.

Chris,

What is it that you want to media blast? I'm assuming it's for the frame, doors, etc. right?

If you have the room in your yard, get a canopy tent with screen and lay a tarp on the floor to collect the media back. It will look/be ghetto, but it will work.

Also, get the best respirator, eye protection and a painters suit. You will be removing paint and media from places you did not know existed.

I ended up buying a 40 lbs blast cabinet, after I got tired of using the one at work.

Hope this helps.

You really do need a bigass compressor, otherwise its just slow and lame. I've used a lot of setups that were half-assed, and the pulsations and inability of the compressor to deliver just made the job suck. When you switch to something that is good, the difference is amazing.

I was hoping to blast my new axle tube. I thought it would be fun to do but now it sounds like I'm wasting my time trying to do this at home.

I know it's no help but I have a guy who does media blasting and because most of his work is on the road doing boat hulls, he takes my small stuff on the side. He's a sole proprietor, so he lets me know when and if he can help me out. He does soda, sand, plastic, dry ice and anything else you can imagine.
Maybe you can find a person like that near you and butter him up so that he'll take your stuff and do it for you. Nothing like having a pro do it, and it saves so much hassle.

I dont know about these smaller soda blasters but sand blasting is pretty much an open hose hooked to your compressor. like Jim says you realy need a huge compressor to have any kind of duty cycle. Mine is a 240v 60 gal 14cfm @ 120 psi and its running non stop when sand blasting.

I have a similar Blaster and I have to admit it works great but has its limits.

You can use it for aluminium or stripping paint and all but dont expect to remove rust from steel unless you have a very high pressure compressor. But to clean an engine compartment the soda doesn't hurt plastics, rubber, oil or fuel lines and washes away with water as it is soluble. the soda absorbes oils and kinda make a sponge like effect and falls off leaving the part oil or grease free. Plus the soda particles are very light and loose their velocity very quickly so you dont blast everything in a 3 mile radius.

I like it, but like i said, it is limited in applications. Parts sodablasted will remain rustproofed for shelving if no washed after too.
