If one decised to split his film, where does he get casettes?
Ebay, most of the times. Buy some films and reuse the cassettes, a good cassette should keep you for at least 4-5 reloads, if some care is exercised when reloading.
Otherwise, MS Hobbies sell reloads (but no empties, if I'm correct). Good company, good products, good service.
However, getting new (read "never reloaded" or thereabouts) is a permanent hunting sort of activity. They tend to appear every now and then in bulk even ( I got some 100 empties from an Ebay seller last year). But if you're not a heavy shooter, some 10-15 cassettes should keep you busy and happy for a good number of months.
Check this: http://www.ebay.co.uk/itm/MINOX-film-unused-outdated-/181053139513?pt=UK_Vintage_Film&hash=item2a279baa39 . Ideally, you'll chase only unopened / outdated film, this way you can be sure the cassette is new and never reloaded. Stay away from other brands such as Acmel or other Minox-like types.
I would advise to stay away from metal version of Minox cassettes too. They jam, badly.
Minox Processing Lab used to sell used Minox cassettes in 10 pieces lots for $10. Brand new Acmel cassettes on ebay were sold in 50 lots of $150 per lot. These are all history.
The best bet now is buy Minox film, keep the cassette for reuse.
Metal cassette jam badly if you forget to tape the outside. All cassettes jam in most rigas.
It is tempting to stick to metal cassettes for the older cameras, but only if they are unused ones.
I am currently re-loading film into unused cassettes (old minochrome stock with type 2 'cap no clip' cassette). As long as I re-use the original exterior tape, they are fine.
I have seen metal cassettes for $20 each on ebay. Bit high. Metal cassettes spools act differently to plastic ones. Best plastic ones were the Acmel - seemed a mite stronger...
The diameter of brass cassette take up spool is thinner than plastic cassette spools. Spool for regular 36 exposure has 10.16 mm diamater. Diameter of pool for regular 15 expousre cassette is 11.43 mm. Diamter of brass spool for 50 exposure is only 9.93 mm. Using brass cassette to load film for Minox other than Riga will cause narrower picture frame spacing, as the rotation angle of Riga is slightly larger than non Riga Minoxes.
following up on Martin, you also cannot mix and match spool with different types of film cassette. 'cap no-clip' spools will not fit into 'clip' cassettes.
Is it possible to make a Minox cassette on a 3d printer?
I think it is possible to make Minox cassette with 3D printer, but costly.
Not to mention the patent issue
The cassette has to be black and lightproof. Could you make a 3D print thru the black liquid?
Is it possible to make a Minox cassette on a 3d printer?I'm building a 3D printer at the moment. Perhaps I'll be able to answer that in a few months time. On the basis of a quick check of an empty (broken) cassette, it looks do-able.
Please keep us posted about your results. And when you're done, maybe you could look into printing a proper filmholder (that holds the film flat) to scan Minox filmstrips in a Nikon filmscanner?
Coincidentally, last week, I sent a plan for a Minox film holder to Shapeways to be printed, to replace my home-made one. If it works I'll post details.
I'm rather doubtful whether it will be possible to make Minox cassettes on a 3D printer currently. The surface of 3D-printed objects tends to be rough and coarse. (They can be polished, but that would be hard for the inside of a Minox film chamber I suspect). Also I believe that the materials are very brittle for wall thicknesses less than 1mm.
I have had some success when needed with the Nikon holder by filmscanusa for the Nikon 5000 but only if the film is pressed flat in the first place, and then only by using the anti-newton ring glass holder version. Ideally I would like 2x glass holders for perfect flatness. For ultimate quality, I have revert to a minox enlarger.
Even a perfect holder is useless if the scanner does not support focusing the lens on the precise 'turning point' of the 8x11 negative. This is the issue I see with epson-type scanners - the lens has a fixed focus
The other problem is that all negatives with riga/minox a/minox b suffer from a fractional pincushion effect on scans which needs correction - this is because of the curved plane film track.
Anyone tried scanning a minox with an imacon? I guess that would be the next step up. Just relying on increased scanner dpi is not the answer unless the scanner can focus.
Why do you say that the plastic modern cassettes cannot be reloaded after 4-5 times? I have reloaded mine more than 20 times, no problems at all. The only drawback I have experienced with a couple of them is that the connecting strip breaks, thus, making it useless.
Can you please explain what do you mean by "making cassettes using a 3D printer"?
Acmel cassettes are of a stronger and "better" finish than Minox ones. They inspire confidence. The old Yashica ones sold in the 70s leak light. I used a few in Minox cameras and the 16mm Minolta type in Minolta MGs and QT cameras.
