    Hi, folks. I'm a frequent reader, rare poster, and I really appreciate this site.

    Anyway, I'm looking for a material that I can use to make a fist-sized bundle that will simultaneously hold a Surefire flashlight, an Asp pepper spray (kubaton-style, that shoots spray out of one end parallel to the body), and a sharper impact weapon that passes the P.C. test, such as a Cross pen. I'm hoping there is some kind of hobby material that I can use to mold something to the shape I want before it hardens (or gets hardened in an oven?). I hope this material will be tough when hardened, rather than brittle or soft.

    The point of course is to facilitate holding both a tac flashlight and a defensive spray in the same hand. For a CQB impact weapon, I'd like it to have an impact surface, or accept an object into it like a Cross pen. Of course, the flashlight could be a Surefire E2D with the crennellated strike bezel, but I'd be very happy if a less evil-looking setup could be found, so I wouldn't have to worry about it being confiscated at checkpoints. Without the flashlight, spray, or pen inserted into it, it should look just like a blob of plastic with finger ridges -- kinda like a handlebar grip for a kid's bike.

    I think there must be some kind of compound out there that fits the bill. Any ideas?

    Only thing I can think off right off hand would be Bondo auto body filler.

    It's relatively cheap, has a reasonable working time, and can be molded to anything you can dream up. A steel or aluminum pin or bolt could be molded in for a hard striking point.

    You can wear a plastic or latex glove to squeeze it to fit your hand.

    Any additional trimming or fitting after it cures out can be done with a Dremel tool and sanding drums.

    There are epoxy puttys that are tougher & stronger, but cost way more then Bondo.

    I suppose you could use Bondo to perfect the design, then make the last real good one out of epoxy putty after you lean how.

    A sheet of moldable Kydex might work for what you're looking for, but you have to heat it up (toaster-oven?) to get it to the shape you want, and you may have to use pop-rivets to get it to stay in the shape you want.

    Kydex can be heated in boiling water or in a cheap toaster oven. Why "cheap"? Because you want to pick up throw away at the thrift shop so you can run it in the garage because of the stinky fumes.

    there are lots of plastic that would fit that bill... so the real question is, what tools do you have at your disposal and what is your skill level?

    having worked in a plastics moulding plant, i say find some old clear scratched up beat up plastic tops to a blender, hamilton beach the best, and grind them up. take a metal pipe
    and place a brass cap on the end and a second smaller metal pipe as a plunger and place the contents of the plastic inside an place the plunger in like a syring, and make the mold out of clay or metal and force molten plastic into the mold using a hydraulic press after its heated up to about 600 degrees. letit cool. pop the mold open and youll have what you need
