I have a Ricohflex TLR for which I got some help here to clean up the sticky shutter. Now I find that the automatic film advance mechanism is imprecise and winds each frame either a bit short or too long. I had a look at the mechanism and saw that it depends on a brass gear which does not look like it can be easily modified. Therefore I think I should scrap it and put in a red window. Any advice on how to do this?

Unleass you use orthochromatic film you should put in a green window.

Thanks for the tip about MattDenton & Waltzflex. Now, does the red window have to be from another camera or will a piece of red plastic do the trick - perhaps the end of a colour negative?

it doesn't really matter too much - either red or green will fog film if the light can get to the film surface from the window. the darker the better, of course. a donut of self-adhesive black felt around the inside of the window will help baffle the light and protect the film.

you may be able to get some red transparent stock at an art or blueprint supply store, if there are still any of those around - or porters.com might have some.
