Building a doll on top of a plastic skeleton.

[james1969]

so, i dipped her fingers in hot tpe. nothing alarming. then, i reheated the tpe and added a sample of each material used in the doll. a flame appeared. i blew on it. that made it worse. i poured baking soda on it. then it went china syndrome. i should.ve been wearing at least one oven mitt when i grabbed it, because it spilled all over my hands when the storm door caught me on the backswing. i then pitched the towering inferno into one snowbank and myself into another. made sure all the little fires were out. drove across the ville at 50 mph with my flashers on to get to the county hospital. tracy, the nurse who cleaned and bandaged my hands, did an excellent job. it wasn't nearly as painful as i'd feared. now i get to listen to doctor paul's safety lectures for the next six weeks while waiting for my hands grow back.

Shit, sorry that happened to you man, i did mention in my tiffany repair post tpe was flammable , i had that happen small scale though, with a test sample i cooked. i was wearing oven mitts so no burns. Pity im so far away,id buy you a beer or two. I hope your project is salvagable, and you recover soon,

Me too!

I guess it just goes to show how dangerous these TPE experiments can be if it all goes tits up. Hope your hands heal up ok in the end and sorry to hear about this.

I know its too late now. . but could a damp tea towel thrown over the top of the burning pan have put the fire out? It works with chip pan fires.

While I admire your pioneering spirit, please be careful. Get well soon.

Sorry about your accident, lenglel. Now I am sure I don't want to mess with TPE. I will just stick with my non-exploding fabric creations.

[lenglel]

it wasn't the heat, so much as the chemistry. more inclined to shy away from the foam than the tpe,
myself.

If that was a "safety test" then it was a total success. You definitely found something that was NOT safe.
Maybe this is some sort of sign. All my dolls start off with showers of sparks from cutting the iron pipe. (A controlled situation that is quite enjoyable actually.) To me this is like sparks of life, a fiery soul that possesses the doll. Maybe this is your new doll telling you she is alive! (And in this case a bit psychotic.)

[lenglel]

either way, i'm looking for something compatible with hot tpe to replace the foam,
to avoid the possibility of future disasters.

fannie and annie both fainted. they're both spoiling me as much as they can,
now that they've recovered from the shock. my wife has been very supportive.
we all thank you for your get-well wishes. if you would like to make a donation,
please see if your local high school is having any fundraisers. my wife and i were
both high school athletes, you see.

Have you seen the topic by the member here who wears silicon bodysuits, to appear as 'silicon girl'? maybe look at buying something similar, to glue instead on your skeleton? save labour and eliminate melting process dont know about cost.

[lenglel]

cost.

the batting and polyfill are both polyester. Do you know if it will burst into flame
when exposed to hot tpe, opendolldesign?

the foam padding is polyurethane.

I haven't found out what kind of plastic the skeleton is made from. It's not the
same plastic as model airplanes, more like plumbing plastic.

Polyester is a plastic, a lot of ropes are made of the stuff and soda bottles are usually made of a type of it (PET). If you have ever melted the end of a rope that is your best guide. I suspect Polyester filling could be bad because there is a lot of air to fuel a fire. From what I remember though is isn't very dense (if that is the correct word) and almost puts itself out as soon as heat is removed.

The real issue with TPE though is it is hard to put out if it ignites, and if you go that far the TPE is pretty much ruined as it messes up the chemical bonds. It's best to treat a TPE fire the way you would an oil fire.

Polyurethane is generally much more resistant to heat.

The skeleton is most likely ABS or PVC, both of which have REALLY toxic fumes when melted/burned.

Hope that helps!!

FYI,

Urethane foam releases hydrogen cyanide gas when burned.
It's NOT something you want to catch fire by any means.

[lenglel]

Found no traces of the other materials among the debris.
I presume they melted, but it's hardly a fair test when
the pan was already on fire from the polyurethane/tpe
reaction. I'm not going to try over-molding the tpe at
all anymore. My mold making skills have advanced to
the point that I don't need to, judging by Annie's new
posterior. Any repairs requiring heat can be done by
removing the part to be repaired from the doll. The
parts will be held in place by friction, and a little bit
of suction-cup effect between the foam (open cell)
and the tpe. There doesn't appear to be any sign
of chemical reaction between them at room temp,
based on my observations of Annie over the past
year. The heating element doesn't get hot enough
to cause problems, either, or I'd have had them by
now.
As I write this, I've got about 12 pounds of
tpe in a covered roasting pan in the oven at 360
degrees F. I made a new insert mold yesterday,
which I think will match up with the new butt
nicely, and generally be a vast improvement over
the crude mold I've been using. I'll post pics of
the results once it's installed.

Pictures, presented in chronological order, of this week's doll-related activities.

This is the left side of the insert I've been *trying* to make for over a year, now.
The interior part is molded first. Then it's hung on a piece of wire coat-hanger
which plugs into the hole I drilled for the vaginal core. The sides of the insert
have thumbs that plug into the openings in the pelvis on either side of the
pubic bone. My last shot from the old mold wouldn't stay in place with the
newly molded gluteus.

One pinch clamp holds the interior away from the melted tpe as it cools.
This picture makes it look like the clamp is attached to the insert. In
fact, it's attached to the wire that plugs into the mold at the vaginal
opening.

A second pinch clamp holds the first one in place.

Front and rear views of the... exsert? The external part hangs
like a basset hound's cheeks.
