    Although, if you searched for a Nikkor tank and found something, it might end up costing less than you expected.

    Since I already have one, I use it, and don't have to feel silly about going out and buying one. I suppose it means I can develop 12 sheets in a liter of chemistry without feeling any extra silliness either, and since my lid fits perfectly, it's a very elegant solution to the sheet film developing problem.

    Seems like some of the bad stuff that's written about this tank on the internet is written by those who have no intention of even trying it.

    Btw, I've tried the rubber bands too, and that works. However, the Nikor is better, even if the price is too high.

    We have some hardcore rubberbandits over here, who have applied the same logic to the price of cars...
    NSFW, in some jobs...

    Personally I do shuffle in trays but since we were talking about tank development... I guess since you already own a Nikor tank then there's no issue.
    I have tried all the varieties of sheet ilm development methods and as a result I have a collection of development tools that I no longer use and perhaps only used once or twice before abandoning it. Slosher trays, tanks etc. all eating dust. I find that the taco method is not only cheap, it is convenient particularly "on the road" otherwise I stick with shuffling

    Thanks Michael, I must try that-

    Cyrus, I've tried those methods too, though the slosher only with 8x10, 4 sheets-
    I abandoned that in favour of rotary, 2 sheets at a time, just to get away from sloshing in the dark-

    For 4x5, the Nikor has the advantage of economy, in terms of container sizes you have to carry in the field, to process 12 sheets at a time-
    you could use a large tank to process a lot of tacos at once, using two or three liter containers, or use a Nikor size tank to process 3 or 4 tacos, three or four times in a row. Give that I already have the tank, I think it would be silly of me to waste all that time, or carry large tanks and containers, or limit myself to less exposures while traveling.

    I look on the price of the Nikor as an extended rental, it goes down the longer you have it, and it seems you can get your money back easily if you need it.

    Hope I've managed to explain to you why the people who buy Nikor tanks might not be as silly as you think-
    Though no matter if I haven't-

    LOL, Oh I don't judge - everyone has their own techniques.

    I have tried the Nikor tanks but did not have a good result due to uneven development, and it was generally too much a PITA to load and unload etc. It is all just preference anyway. FOr me, the $300 could be better spent but that's a personal opinion.

    There is a complete Nikor 4x5 tank on eBay right now for BIN of $150, that's a good price.
    I have no affiliation with the seller.

    I use one for 4x5. The main issue is developing time combined with agitation. To little of either will create streaking. Min of 5-6 min, agitate every 20-30 sec. A preset helps. Tried it with c41 and got poor negs mostly due to the short times. Load emulsion IN every time or the SsStrap will tear your emulsion. Never tried rubber bands or without the strap...might test it without the strap to see if that makes any difference. Stay well.

    Sorry. Pre WET not PRESET!

    Re: Those Nikor tanks (for 4x5)

    I have a nikor 4x5 tank which works fine as long as developing times are over 5 min. Agitation every 30 sec with an invert and a twist. Just make sure you load the sheets emulsion in. A prewet bath seems to help as well. Fill/dump times are about 20sec or so. I haven't tried it without the ss strap. I have tried it with c41 in a heated water bath but the developing times are too short. Stay well

    Re: Those Nikor tanks (for 4x5)

    The tricks I find with the Nikor tank, most have been given in this thread.
    1) Load it the opposite of a film holder the base should be on the upside of the curl.
    2) My tank is a little large for the 4x5 reel set, I use a spacer so the reel won't piston.
    3) Prewet
    5) 5 minute + developing time I agitate 10 seconds every minute.

    Bought mine in the mid 80's for about $50.

    Re: Those Nikor tanks (for 4x5)

    As much as I'd like one of these Nikkor tanks, I will do as I have on another site, when it comes to hard to find items, and suggest, instead of everyone scrambling to find old tanks, photographers use influence or tech and build brassiere to use tanks and racks, by either having an entrepreneur of simply a skilled Welder make SQUARE tanks, with round mouths and caps, and a similar multi-rack of development sheet film holders, trimmed down in weight/size,(after all, you won't need the hangers) and arranged into one piece units, so you can have a couple loaded racks ready to go into the tank, after the first or tenth run.

    A permanent gasket or a replaceable one can secure the top, and a plastic lid with a snug fit would make pouring/filling no worse than filling a round tank.

    Or, instead of SS, 3D print or Router or CNC construct a polymer block and lid, and complete with two hinged locks, opposite sides (the same with a SS tank and lid), to keep it liquid tight and snap together racks for 6-8 sheets (so a narrow profile is easier to handle than a Kodak Rubber Tank Size Unit.

    If there was a way to make an acceptable, tightly sealed LEGO tank and acrylic inner rack, you could do about the same, or, just build a wood box, using the wood gasket method, epoxy paint it, add cork, rubber (bike inner tubes) or leather gaskets and get busy with that back log of film.

    I use the rubber 4"x5" Kodak tanks, and would like to find more, cheaply, but some times the notion of a tank that could do inversions is just too tempting to give up on, but I have no doubt that many of you could do for yourselves without paying outrageous prices and difficult to use vintage tanks.

    IMO.
