Quote:Did you ever consider casting some of your parts in aluminium?
Until I discovered the higher strength resins, I thought I'd pretty much have to cheat (as in the current alpha arm), go the CNC route, or have aluminum castings made by a friend that works in a foundry. I'd never considered backyard casting. Something to think about if the resin doesn't work out for some reason!

Quote:Okay, now by "compressed air" do you mean an actual "air compressor" variety, or would a can of PC duster work?
Since I (still!) don't have an air compressor at home, I use just that...canned air PC dusters. Obviously a compressor is better, but canned air will work. You have to be very thorough though, and make sure you get the nooks & crannies. Because the cans rapidly start to chill & freeze, loosing air pressure, it's best to have 3 or 4 laying around at a time. Especially if you've got multiple molds, or larger molds.

Quote:How long does this stuff remain suspended in the air? I do most of my casting in the basement/laundry area, so I want to protect the family as well.
This stuff's got hang time because the powder is so fine, so you'd either want to take the molds outside to dust 'em (make sure you're upwind
), or build a dust box to keep it under control.

Quote:And... does the resin come out the nice silver color right out of the mold, or did you buff it afterwards?
That is straight outta' the molds
In true cold-casting, where you're mixing 2-6 parts atomized metal powder (slightly different material) to 1 part mixed resin, you'd buff or patina as you would a real bronze casting.

Of course, if you're young, or not from the U.S., or both
, you won't get this reference. Sorry!
