Plastic vacuum models

[get2grips]

For reason I am reminded of the boy at school who took a bet that he would not put a certain appendage in the hose of a Henry. It ended with him screaming 'turn it off. turn it off'...

Pictures or it didn't happen...no...wait...

To be serious, how will you get a good seal?

Come on Gareth, everyone knows you only get bad seals in the zoo.     You've got to go to the North Atlantic for a good one...

Well from what I have seen on you tube you place the warm plastic sheet on the master, the vacuum cleaner sucks from underneath at the same time, the board the master rests on is full of holes so the sucking out of air is even across the plastic

It was very hard to write that without making it sound rude or full of innuendo

Doesn't matter Steve; this lot could find innuendo ANYWHERE

What do you mean "This lot" ?
I trust you're not excluding yourself Gareth ? 
Cheers - Phil.

Sorry if I'm being dense, but surely the board must be in a bag or something attached to the vacuum cleaner, or you wouldn't get any suck through your holes?

[You're right, everything in this thread screams "that what's she said".]

[Fenton]

yes sorry the unit is sealed with the tube of the vacuum attached to it

[Orcs]

Just to bring this thread down to the normal level

Q= "What do you call a 70 year old woman who can suck an orange through a hosepipe"

A= "Darling"

I'll get my coat - the one with the buckles at the back.

Ah! Now it makes sense.

Sorry, another question. (I have been endowed with an inquisitive mind. Some see it as a gift, to others it's just like a monkey's.)

Presumably the holey board is the key. If the holes are too big then you'll get dimples in your hills, too small and the plastic may cool before you've got sufficient shape. Does the configuration of the board matter that much or am I over-analysing?

 

[Fenton]

I dont know mate...I think its going to be a bit of trial and error but people seem to use a peg board with a wire mesh over the top

This sort of board 

[fsn]

Good luck with it. I'm a great one for the theory and the thinking, but the practical side of it just makes me tired.

I also have a short attention span that means I

[Fenton]

I do something simil....Oh look a rabbit

[get2grips]

How do you heat the plastic?

[Fenton]

Either in the oven or the way I am thinking is to have the plastic held in a wooden frame which is hinged to the box which will flip to hover over a single or double electric ring

[Fenton]

This is my CAD design for it

Steve, whilst I admire your technical and engineering know-how; wouldn't it be easier, cheaper and safer to either buy them or ask your better half to sculpt them???
