    Compressor & blast media tech

    With all the changes to the rig, I find myself wanting to do a lot of cleaing: Prep the engine bay for paint, clean the front and rear housing for paint, clean the new steering boxes, etc.. There aren't enough wire brushes in the world to get these all done.

    So I am looking to upgrade from my 20+ year old Sanborn 3 hp compressor to something that will run a sandblaster or soda/media blaster. Looks like I need to get at least 10 CFM at 90psi - so far the best bet for a new one seems to be this, it has a big tank and a cast iron belt-driven pump; don't want to mess with the new oil-less direct drive gizmos.

    Also looking around the garage to find space for a blast cabinet.

    What are you guys using?

    Does soda remove paint and/or rust?

    Anyone ever build a blast cabinet? Found lots of plans online.

    That would be a good choice for a typical home mechanic garage and about the size of my compressor. It handled the demand when I sanded and painted my Bronco but was running almost constantly. When I upgrade I think I'll go with something in the two cylinder variety and around 80 gallons. Looks like those run around $550-$650.

      I would say get a 2 stage 220v of any brand your comfortable with. The single stage 110v compressors can't keep up with much. You will be glad you did when you start running a blast cabinet.

        I made mine from an old cooler/Icechest. I can only do small part in it.

        I've always used play sand.

        EDIT:
        On that note. An old "deep freeze" freezer would make a good cabinet. I know you can find them on Craigslist all day for free/not running. You dont need it to work, just the box and lid to be intact.

          Read here for some good blasting info.

          Soda will not remove rust, sand can be too abrasive on thin materials, (thanks Cage Dave for this insight)

          Weighing my options now for DIY blast my tub or pay American to do it. Worst case quote was $750 including a epoxy sealer primer when they are done blasting.

            One of the Saturday morning car shows had a car blasted and primered using a baked on powdercoat type of primer. It was really cool and I'd like to find out if somebody local does that...

              Found a good PDF about routing lines for keeping things dry, thought I'd pass it along.

              Also found that the 4 year warranty on the Husky compressor doesn't cover the motor, pully, flywheel, gauge, piston rings, etc. - all the parts that you think would fail are considered wear items. They have an extended warranty for $80 that is probably a pretty good idea. Also learned that service for the stationary units is on-site, which is kind of cool. Hate to have to lug that thing back to the store.

                  I use a small media blast from Harbor Freight. Ony can fit small parts. I have found the glass doesn't leave the surface too rough and easily primed for painting. I wish I had a larger compressor as my 110 can't keep up. Have to stop and let it catch up.
