Re: preparation of styrene kits for painting

James F. Brewer <jfbrewer@...>

I have a one horsepower compressor with storage tank; for general cleaning, I usually spray the grit at 20 psi, or a little less; if I'm just trying to remove some lettering (i.e. change the car number), I usually set the gauge at about 8 psi.

The compressor I am using is a little undersized for the blast booth; when doing a car or some trucks, it usually is not a problem; however, if I want to blast several models at once, or have a particularly large project (recently blasted a friend's B&O EM1 brass loco) it does tax the compressor. I'll eventually upgrade the compressor.

I have a Paasche "Air Eraser"/Sandblaster, but haven't used it for
quite some time. I'm getting all my "stuff" set up again and even need
to get another air-compressor. But what PSI have you been using for
sandblasting? I tried using Aluminum Oxide only before, but I recall
not getting good results.

The compressor I had was a very small one for spray-painting, and I
think it may not have produced enough PSI or Volume.
