An ally at last! We are on the same wavelength Bastuminasiasimthing. I had a GREAT tip from JohnP (thanks again) about how to make a SIMPLE HOME MADE VACFORMER, which I havn't yet put together..., but otherwise there is the old hole-and-plug method us schoolkids used to make model aeroplane canopies with. Carve a plug mould out of gelutong, cut a matching hole in a piece of ali sheet and clamp a piece of acetate over the hole. Warm gently over the gas cooker, then shove the plug through the hole. I had hoped that the spare screen from my Maxi-model M6A might be persuaded to fit but it's a no-go
Hey, since Mr. JohnP is around... Would you mind shareing your idea about the vac forming gizmo?
Howmet, your little simple idea sounds quite allright too, I wouldn't mind trying that out either. The plug mould would then be shaped on free hand then I suppose? I need windows for a massakerd Scaley Mini and also if I start resin castin there will be a great need for a good window forming technique.
Thanks for showing your work as you go along, I'm waiting for new updates all the time...
Mr b, the vac forming gizmo was in fact down to some ingenious guys at Car Model magazine back in the '60's.
Basically it was a wooden box with lots of little holes in the top and a big hole in the side for you to plug in a vacuum cleaner. There was also, a rubber seal around the top edge.
The mold would be placed on top of the box (over the holes) and the vacuum switched on. At this point air would be drawn in around the mold and through the top holes of the box.
A plastic sheet pinned to a wooden frame would then be gently heated until the plastic began to soften. The frame/sheet would then be pressed over the mold and down onto the seal. Schloop - a blob was born!
Now no more of this "off-topic" gizmo talk please. Let us now return to Mr howmet's thoughtful and considerate VMG handywork
