Generally plastic of this kind would be of bad quality would it not?
I can imagine it wouldn't be the greatest quality... but... if it is some form of simple epoxy resin it could be pretty amazing stuff... as far as precision/weight go I'm not sure, but it'd be worth a shot over trying to make a precision injection mold, especially since I cant think of any way to break it down to less than 3 parts, and 3 part molds get very very... very complex to deal with :-/sniperninja said:They have plastics that don't need heat, you just mix and pour it into the mold.
damn. You had me all excited for a second xDbobgengeskahn said:ME as in Mechanical Engineering.
And this is my thinking for trying it, however the seal that is created in RS vs. the 'seal' (or lack of) that is created in airsoft may cause an unacceptable bleed of pressure. The other concern I have with a boat tail would be exposing the fins to the air flow from the cylinder (planning for a HPA set up) would cause the BB to rotate counter to the intended spin once it leaves the barrel. I may just be over emphasizing the effect in my head... all the more reason to testI think boat tail, mostly because it work very well with match grade RS bullets.
On a slightly more serious note, I have been looking all day and have yet to find a way to build an acceptable mold. I have mainly been looking into injection molding and some rapid prototyping techniques. Anyone have any ideas for an accurate cheap way to cast things?
