Gino P. Quintiliani has written an excellent article about how he built his own vacuum-forming machine. He''s supplied a list of the materials required and a step-by-step guide to construction.

cool,

i used to use vacuum formers at school, never thought how easy it would be to make your own.

however wouldnt something vacuum formed have almost no detail on the outside? we only used to recreate simple shapes as the casings for electronic devices, using pretty thick ABS sheets.

maybe using thinner sheets works better?

cheers

Hi Joe

That depends on whether you use a male or female master i.e. whether the sheet plastic is formed over or into the mould.

Using a female mould, you can get good detail, but you need to drill small air-holes through the mould to create a vacuum and allow the sheet to be forced into it - this is what causes the small pips visible on commercial vacuformed kits.

Hope this helps

maybe stupid, but for what can vacu forming be used (not in terms of aircraft)

Nice article, and a simple method of making a Vac former.
as to what to make, canvas covers have been metioned and a few others. First thing that comes to my mind beside the obvious aircraft stuff, is scale thickness fenders.

Interesting article, but one most important item was left out of the list of items needed. the VACUUM SOURCE. What do I use a shop vac?, a regular vacuum cleaner..How much vacuum is required?

Hi there

Any vacuum cleaner should work. I've read that you should switch it off quickly after the vacuum is achieved, or you risk over-straining the motor.

All the best

Interesting article.... could we get some "diagrams", as I got a bit lost on the use of the reinforcement basswood.

A nice vacuform would be excellent for creating things like wall sections and roofing as well....
