Hello Everyone, Sounds like the preferred choice (gratis) has been found, but... At my local Wal-Mart and other tool stores you can buy a "sandblast kit" for around $15 or so. No cabinet, just the siphon hose, fittings, and the blast nozzle. It's rather large for the use that spawned this discussion, but it may be useful information to someone in the future. It's marketed under the "Buffalo" brand. Cheap stuff, but if you only use it twice a year or so, it should get the job done. IMO Royce, thanks for passing along the Harbor Freight ad.
Later, Trent
