Foam Discarding Sabots

Unread postAuthor: c19o » Sun Oct 14, 2007 11:06 pm

I was making sytrofoam wheels for my science project and i thought of using one of them for a sabot or wadding.
Heres some pics of how i made them...

Grab a piece of your barrel...

Trace with a marker...
Image

Cut with a bandsaw...
Image

Glue items in or on the foam

Awesome, although how are those poor buggers going to sell their house now :lol: :lol:
Sabots are becoming popular lately, bit of foam to clean up but who cares.
Very nicely done. Love that damage! :P

rather than use a bandsaw for foam I prefer to take a piece of barrel material and sharpen the edge similar to a hole saw:

*follows JSR's method, finger slips* OMG my index finger!!!!!!!!!!!! The blood, the blood!!!!!!!!!!!!!!1

I, too, think that the bandsaw method is too time-consuming, leave that for tougher sabot materials like plywood. What Jack suggested is good, as is a short bit of barrel and a hammer in case things get tough(heavy blunt objects solve everything!!!).

EDIT: Wow, it looks like he was stripping for the tank. Totally owned the sign, man, and by now Ive forgotten who started this thread, oh well, congrats to whoever did it.

Was a joke^^
I only mentioned the hammer because it has helped me through bits of tougher potatoes when I didn't feel like getting a sharper object.

Oh, and Jack, thats only with styrofoam, the harder type of foam(I forgot what it is called, sometimes used to hold flower arrangements together? I get it at Michael's) will succumb just fine to brute force.

@ JSR, I tried that but it just ripped the foam unevenly, maybe finer teeth would work. Gotta love tanks!

@BC, Yea it was mine, we were goin to sell our house but didnt so I got a free sign. :D

@Novacastrian, lol that made me laugh

fair enough but that means it's easily crushed as a sabot

I don't use teeth, I just get it down to a fine edge like a muzzle knife - though this usually works best for metal barrels.

It comes out as 3 pieces usually, only once I was able to reuse one.

Next time I go to wall-mart I'll pick up some of that hard foam windshrike was talking about. I'm sure I'd be able to reuse it at least once hopefully.
