Thank you Ian, I have in the past done quite a fair bit of reversal processing of FP4 and FP4+.

I have always used a tungsten 60W bed lamp stuck on my darkroom wall for the second exposure. Generally I have taken about 15 seconds to get the film off the reel, then I expose for around 20 seconds each side, then the film is in the light as I re-wind back on the reel. The exposure was obviously all right as my films came out quite well.

I have an application in the new year for B&W trannies and I actually was looking on Apug when my search turned this thread up.

Except for two chemicals I have everything, so I'll get them and have a go next year.
