I tried to cast a bottle stopper in one of my little clear mixing cups. I had to use something rather large because i was trying to cast a scorpion in the blank.


It looked outstanding as i sat it in the pot. I raised the pressure up to 40, and left it for an hour. When i opened the pressure pot, i noticed what looked like a HUGE air bubble up against one side of the scorpion. When i picked the cup up, i then noticed a bad spot on the side of the cup. when i tore the cup off the blank, the PR had this weird crack/flap thing going on in the exact spot as the bad spot on the cup. the air bubble in my blank appears to be a crack?


very weird business. If anyone knows more about what happened here, please let me know. I think that was going to be a killer bottle stopper and i get one or two scorpions in my house a year, so i should have another one soon to try again!

I'm thinking that the cup failed due to the heat of the reaction and the weight of the PR, causing loss of partially gelled PR.
 
that is funny! good stuff.

there was no loss of PR. all the PR stayed in the cup, and there were no holes evident in the cup. just a spot that looked like it got too hot. thats not to say that somehow a blowout didnt happen in the pot. the cuccle / crack thing is probably a bit bigger than a quarter, but about as thick as a piece of paper.
 
OK, perhaps passing gas wasn't right. But there could have been gas inside the
scorpion that expanded from heat when the resin was curing.
 
Was the scorpion dried out good? If he was "fresh" when the pot went under pressure it could squeeze any air from inside the scorpion out into the pr where it would run along the bug forming a thin air pocket or as we snakeskin casters call it the "dreaded silver skin". Just a thought.
 
i bet that was it!


When i catch them, i put them straight into a tub of alcohol, wich pretty much does the trick as far as killing them, and starting the drying process. This guy was actually only a couple of weeks dead. I bet there was moisture stuck inside. Of course it doesnt take much.

Can you cast without using the pressure pot?
 
That was the demise of the dinosaurs, you know.

They all left so much methane that the air became flammable. One lightening bolt-

BANG



Gone! Blew up the whole planet!

Well, there you have it folks. The entire theory of a gigantic meteor impact and what actually happened to the dinosaurs in just a brief few posts shot to hell and totally proven to be wrong.

And the good part is ... it actually makes sense ... to someone! Now, just where is my wacky weed as I want to get on this ride!

Good humor and quite funny postings folks! :biggrin::biggrin:
 
Hmmm...every now and then I find a field mouse has worked his way into my living room....you think I could throw him in some PR?:wink:

I also have a lot of those cool blue-tailed lizards climbing all over my brick, could I cast those?
 
Hey,

I live in Wisconsin, where they continue to talk about "cow gas" and it's impact on the environment. Well, look at the size of cows. NOW, look at the dinosaur bones in the museum. When that sucker "passed wind", a hurricane resulted!!!

So, MY version is more logical than that silly meteor mythology!!

AND it makes a MUCH better Visual!!!
 
Okay, kinda getting back to thread:tongue: Is this really a problem with the scorpion or with the cup? I've cast alumilite in paper dixie cups before with seemingly no problems. Is plastic different, or does everyone feel this is the scorpion causing the problem (farting or not:tongue:)?
 
Dawn inadvertantly casts in these clear cups all the time.

She gets too much going at once. Then, before she is READY to pour the last cup or two, WHAMMO it SETS!!! No bubbles, no pressure pot, just sittin on the counter.

So, no the cup didn't pass gas.
 
I have cups full of alumilite too, and there is nothing I can see wrong with them. Might be a few tiny air bubbles here and there inside, but nothing major. The scorpion in a bottle stopper sounds really great though. Send me a scorpion, I'll give it a try and see if the alumilite might work better over the PR. Can't imagine why it would though, other than the heat might be a bit less.

You think the heat is less? I would think the alumilite heat curing would be higher than PR, since it cures faster. But I could be completely wrong, and quite often am.:tongue:

We caught a mouse and put it inside a vacuum bell, it was pretty messy, and also cruel but very messy, my wife made me buy a new silicon base pad and wash the bell out with bleach, Man those lizzards are cool, don't hurt the little critters says the dumbass that implode3d a mouse????
 
that is nasty.


i mix my PR pretty hot, usually at least 10 drops. Could that maybe be a contributing factor? maybe less MEK, and more cure time?
