I need to repro some auto parts with crystal-clear (or water-clear) material. From looking at the net, Acrylic is difficult to cast (heat, pressure). Is there a 2-part water-clear substitute? Poly-something or other? UV additives available?

Have you used it and what were the results?

Yes, two part acrylic around copperheads and rattle snakes. People shudder when they saw them.

I cooked one by adding too much catalyst. It loooked flaky like fish. The acrylic cracked all over.

Put the snakes in the freezer to put them to sleep. Then arrange them in the bowl the way you want them and pour the mixed resin in. Wait too long and the snake wakes up.

Years ago they used to sell a kit to cast acrylic resin called plasticraft.
you could cast key rings and paper weights with it ..inbed flowers coins shells into it etc.
I had one when I was about 10 years old some 33 years ago.
There was non of this pressure stuff you mention involved.........although you could put stuff in a low domestic oven to speed things up a bit.
I do know of a UK company that supplies this resin.

I bought a gallon of it to play with a while back.........but before I got the chance the whole lot went solid in six months before I had chance to have a go with it .....so don't go buying large quantities of the stuff.because it looks like it has a shelf life.

all the bestr...mark

The Castolite Company used to supply products like that. I used their stuff years ago to make some repro plastic parts, but I think they are no longer in business.

This company seems to sell the same kinds of products:

I've never used their products, but I know of a company that uses them to make repro knobs and such. They have several clear varieties. Somewhat expensive, and nasty stuff to work with it looks like. FWIW

Castolite rings the bell. I was embedding snakes and twigs in it for coffee table centerpieces.

A local company, in Chattanooga Tn. I have used thier products. Seems they have been bought out or changed hands thou in the web page. They were offline for a while.

Thier two part casting resins, pour-a-cast has a 1% shrinkage or less. Exact copies of your project, or broken part.. etc.. I have made knives with the stuff and sharpened them to cut paper. Hard.

If it is a dry ice freezer the snakes are out by the second breath, but I don't see how you arrange a frozen snake - he'd snap like a twig wouldn't he.

They don't die, they hibernate. Blood still flows. They are like a limp cold rope.

Yeah, kinda mean to snakes. They were kinda mean to me a time or two. I almost got bit a few times.

The most dangerous snakes are the ones you take into a cage, they don't feed and use thier poison up. They have full poison sacks waiting to pump into you, as they bite you they rock thier head back and forth forcing all the poison into your flesh through the hollow fangs. Thinking on that? do you feel sorry for the one or two I put into acrylic?
A fresh milked snake has little poison to hurt you. More like a bee sting. I never realized thier fangs folded up into thier mouthes till I had six or seven to sell.

I toyed with snakes paying for my hunting trips with thier hides, rattlers. Belts, buckles, boots, sew ins for leather jackets.

Once on a hunting trip, My buddy Leon, I was sitting in my ford van eating lunch, he opened the door all wide eyed, said.. I didn't see the catchers bag so I let the big one loose in the van. I drove that van looking between my feet for several weeks.

Ohh a little more trivia? 50/50 percent etheleyne Glycol and glycerin.. Soak the skinned snake hide in it for two weeks or more.

The glycol dehydrates it and preserves it, the glycerin replaces the water and softens it.

When you are skinning a snake, start on it's head, trim the mouth out, then work the skin off it's head, once you have it rolled down it's neck it is like a pair of panty hose and unrolls, that it till you get to it's pecker a and butthole *(a snake has two peckers, gods way of keeping from draggin it in the dirt?_) .. then the skin tears and you lose the last few inches. A good fat Georgia rattle snake is about a foot wide after you split it on the belly seam. I'd typically get $35-50 for a good sized hide. (in the 80s)

Copper heads are much more aggressive and mean, they will run out at you. They are smaller thou, Head the typical diamond shape, Head a bright copper or in the case of a pilot snake a dull brown mottled color. A corn snake has similar colors, but harmless.

Cast in Acrylic, they are beautiful, thier colors preserved forever. Killing them without making a mark on them? how else?

My neighbor used to take them by the tail, pop them like a whip and pop thier heads right off. After twenty years of doing that, he missed one day and got bit. His arm swelled so big they had to split the skin so the blood could flow, the swelling had went as far as the skin would stretch. He has ugly scars up his arm where the skin tore as it was being scalpeled. He won't fool with a snake now, except with his 12 guage.

Synair did have clear acrylics.. I don't see any now.

Any dental supply company will suply you wih clear acrylic resin in powder and liquid form when mixed together they form a dough which can be packed into moulds and cooked in boiling water under pressure or cold cured in a hydroflask till hard this pressure is needed to avoid perosity .Good luck Alistair ps pity you were not a bit nearer I could explain it and show you better

Brings back stories about my dad and uncle... In the 20s and 30s - there was not a lot to do in East Tennessee and North Georgia..... They found lots of uses for snakes that you might not think about today. Walk down next to the river or a lake at night and you would be amazed at what comes out to see your spot/flash light. Different world I gues....
