Oh, what metals did you melt? Did you manage to melt aluminium?


Sorry, school stuff mostly.

yes, aluminium, some brass alloy(not entirely sure what it was), a few bits and peices of random things. can melt down cans and stuff easily

Damn! You should try aluminium casting, of course then you would need to machine out the moulds and for that you would need a mill bench or a friend who has one.
I have a plan for moulding some thermoplastics into rifle magazines using method similar to the one on the picture. I have made the CAD model for the moulds, now I need someone to CNC them.

Nice, I have considered casting aluminium, not sure what to make though? so far I have not made anything of any actual use in any of my artsy abilities, so I am probably just going to continue making useless little trinkets for awhile. of course I will eventually get that railroad spike knife done...

Well

hello, it has been a while has it not?

Oh yes quite awhile.... how is you lab?

i'm doing fine now that it's summer. :P

what have you been up to?

Working on making rockets, I am currently having trouble creating enough force with my fuel to make anything move... at all...

I've blewn up an old barn and some other stuff using pipe bombs but I've never made any rockets ;d How are you planing to get close to linear thrust so it's not just a big bang and some obejct flying in a random direction?
The only way I'm seeing this would be with some kind of a valve which would be regulated by a pressure sensor, either mechanical or electrical.
