Excellent work - there is definitely a market for 3d - printed replacement reels compatible with Lomo tanks. STL files for the other LOMO parts are available already but these are the first STLs for reels I've yet seen. A printer with a large bed size will be required to print these models in one piece. I have a regular size 3D printer which is too small fiorthis job, but for example the Creality CR10S5 could do it. The other option is usually to split large models into parts and print then reassemble, but I doubt this would suit the spiral. Currently I don't have the bigger Creality machine .... yet anyway. As for the print quality then I think 0.1mm would probably be a fine enough resolution to avoid scratching the film, but I'd need to test that. best Phil

Hello all I have just found this posting whilst searching for Steeenbeck tech info. I work part time at an archive and we have four (!) Steenbecks in various states of disrepair: a model 1900 (16mm); a model 1901 (16mm); a model 4000 (35mm) and a fourth 35mm machine model as yet undetermined. We have the operator manuals for each machine but we would really appreciate copies of the tech manuals to pass on to our resident techie. Can anyone help with copies (any language) or point me in the right direction. thanks and greetings Phil

V interesting thread. I've done some BW reversal processing and I can confirm that the process requires an active first developer. D19 is one of the commonly used formulae. Ten minutes is a typical time. Of course D19 is no longer sold as a ready mixed product but it can be easily mixed from scratch. I also add a bit of potassium thiosulphate (silver solvent) to give it an extra kick. I've also read that Dektol (paper developer) is a good choice for the first dev, but I've yet to try it. hth Phil

Just to add my $0.02 regarding DIY processing in a Lomo tank: I've successfully processed 1990s K40 Kodachrome as both BW neg and BW reversal - results were okay if a bit murky - it's possibly worth doing if you can pick the stock up cheap or free. Older Kodachrome (eg the K II on the right of your pic) I'd use as leader - it's not worth the effort IME. The Vision2 is an earlier version of the currently available Vision3 stock and can be processed as C41 if you want to do it yourself. Otherwise there are pro labs who will do it in ECN (its native chemistry) for a fee. Bear in mind this is a colour neg stock and not reversal. greets from London
