    Home Sandblaster

    Does anybody have one?

    Worth getting??

    My compressor is getting on a bit but I think it's good for ~12cfm. Will that do the job?

    I have front & rear wishbone/coil suspensions and all brakes to do. From my experience, I won't get much change from $200.

    I have one. My compressor is a 13 cfm unit and it can't keep up. Even when it was new it couldn't keep up with the air demand.

    BTW, the sand needs to be DRY! I haven't used the blaster for years.

    I haven't tried commercial blasting grit.

    You're right about the cost of commercial blasting, I had a few items from my DeWalt radial arm saw blasted and it cost about $150.

    You can always make up an adapter hose with a "T" piece and borrow a mates compressor to join to the volume of the two compressors.

    Also make sure you use the largest bore size hoses with the shortest appropriate lengths you can find, for both the adapter and blaster supply line. Doubling the bore diameter size increases the volume at the same pressure by a factor of four and reduces both resistance and turbulent flow along the walls at the same time.

    I think this is part of the problem with my set-up - too much pressure loss along the air line. Maybe I should try a very short air hose.

    A very short or very fat air hose. Or both.

    The other thing is to come over to Prestons, Cookey has recently bought a 100CFM/150PSI compressor.

    Brilliant, Lotza!!

    I can borrow "Her" compressor that she uses for art. Its 8cfm so I could have 20 cfm in theory,

    I knew they were gluttons for air so I've not thought much about it because I thought it would entail a new compressor

    BTW I just realised I have 5 wheels as well.

    Added up I may as well buy this:

    Another trick is to find an old compressor unit with a dead motor etc, remove the compressor and fit a male fitting (or two) onto it and run the two compressors into the tank. You then take your air supply for the blaster off this additional reservoir and let it charge up from both compressors. It gives you extra volume for short episodes of blasting.

    In the chook shed I have installed 100m of air line in the roof with connection points about every 20m, but the flow losses in the length makes pumping up tyres etc at the wrong end very tedious. Having the reservoir tank insitu and charged its like working next to the compressor. I would still do blasting activities close to the compressor.

    Hi, I have a little unit, but found it a lot quicker, cheaper and less frustrating to take a slab of beer to the local fabrication shop, and they just do it with there next project. I find that the grit gets moist to quick, and in the cabinets, it gets contaminated to quickly. Good luck with it.

    My sand blaster is one that looks like a spray gun with a nozzle, something like the one below. One fills the pot with sand rather than paint.
