I'm building my own cine lab also. This shows a simpler design in terms of film path but it's also much smaller than mine. The downside is that the speed is lower. According to my tests and experience, I would estimate it's about 0,5 meter per minute which is too low for perfect processing.
BUT, this said;
This one is quite compact, seems to be quite reliable and is not too difficult to construct. And it seems to work, which is most important.
Thank you for sharing the youtube link. This is really cool. I have now a competitor .
The continuous lab I'm building is for 16mm and has enough dark space for at least 2000ft reel. It will process ECN-2, ECP-2, E6, BW and BW reversal, 8mm, 16mm and 35mm at lower speed. Just finished designing a new control panel unit. http://sorsa-tv.ath.cx/~antalh/eloku...anellijoo6.png . I hope to get it finished finally this year.
