1. What is the minimum size compressor that's effective?
Depends on what size the blasting unit is, nozzle size(s) on
blasting tip, tank storage, pressure and thus cfm required.
2. What sort of work enclosure is best?
I like total enclosures, vacuum exhaust, dust collector as
needed/required for your circumstance, cabinet lite, side or front
or both for loading, incorporated sand, bead, media recycling or
3. What kinds of media and equipment (brand names) have you found
I use, 99% of the time, glass beads (very small ones) on bronze
sculptures but also use same setup for jewelry (just have to be
careful not to drop work pieces into the cabin ate as then I have to
go fish tim out, ,,, very doable but it takes some time. I use glass
beads as they do not remove metal just the "stuff" stuck onto it
that I am removing. Basically the metal surface gets peened by the
beads, like hitting it a zillion times with a wee wee tiny ball peen
hammer. ... Removes investment, fire scale, rust, paint, etc. very
well and quickly. Bigger beads or sand can be used for more sever
texture if needed, just a pain to switch the media from the cabin
ate, then cleaning the cabin ate VERY WELL when switching back to
the small bead media. GREAT surface preparation on bronze sculptures
Also, for our Master Model Maker, or anyone else, has anyone
experimented with sandblasted textures on Ferris hard wax? It may
be a really dumb idea, and there may be better ways to achieve
interesting textures without embedding sand or silicon carbide in
your wax model.
Never tired it but seems that it would allow for some potentials.
Cynthia or I would probably just do the texturing work with
"regular? wax working tools, what ever they might be for you,
