Re: Re: micro film making

I advise you to buy some proprietary film (advertised as such). Clear shrinking dope may work but I would bet against it. I used a small can which held 35 mm photographic film with a hole about 3 mm dia in the side at the bottom. Pour the film from the can, holding the can a few cm above the water surface.To make film large enough for eg F1D you will need a tank about 1 x 1.5m with a depth of about 3 - 4 cm. That amount of water will weigh 50 kg or more.
