    Leitz focomat 1c questions

    hey all,

    I've just received my focomat 1c yesterday in the mail, and after getting it all put together last night, I seem to have a few extra pieces that I'm not exactly sure what/where they go/go to.

    here's a picture of the culprits .



    Unfortunately, I don't have space to put this enlarger up for use as of yet, but sometime soon! I'm just calling it "future planning".

    2ndly, any ideas on replacement bulbs for it? The one that came with it is a GE 75W bulb, but it flickers a bit, especially if setting something down hard(ish) on the easel, like the grain focuser.

    Lastly, the easel that came with this particular enlarger is a 14x18 sized one. I've tried searching for more info on it, especially since I've never seen a Leitz-branded one this big before(lots of 8x10 ones however). Any ideas?



    thanks for your help!

    cheers

    -Dan

    and some others, just if you're interested, or have any extra helpful info on getting started with this awesome enlarger!

    check the wiring for the bulb.
    sounds like a short somewhere.

    can't help you on anything else.

    sorry & good luck.

    Dan, I had one bought new around 1960 that looked very much like yours. That white chord to the bulb differs; mine was black with a connector that plugged into a receptacle on the top of the column and the receptacle was wired up the inside of the column. There was a screw at the bottom of the column on the backside for grounding the enlarger. The bulb was an opal (#212, I think) certainly more than 75W. I would check the condition of the interior of the top half of the dome as it may have deteriorated some, then check for uniformity of illumination at the easel ... you may find that you'll have to play with the height of the bulb in the housing by loosening one or more of the three set screws at the top of the housing in order to improve the uniformity (can't recall if the mechanism automatically keeps the bulb centered in the housing). My lens was the standard 50mm/4 Focotar. Hope this helps.

    Hi guys,

    thanks so far . I'll double check the wiring, the person who sent it to me re-wired it, since the original wiring was completely shot. I took the top bowl off(with lightbulb inside), and took some mild dish soap and water, and dampened a cloth. I proceeded to clean it, and it looks brand new! I've just adjusted the cam, so the "auto-focus" is working just as it should. Boy, for a 50+ year-old enlarger, this technology sure is cutting edge! Very handy feature, and sure speeds things up by not having to re-focus every time I change the size of a print.

    g'night guys, thanks for the help. Any further suggestions/recommendations are of course, more than welcome!

    thanks

    -Dan

    Dan, I don't have a clue what those leftover parts are, but I'll bet that if you query the Leica User Forum, you'll get some help:

    Do you have the easel locking mechanism installed? Extras might be part of that.

    You need short neck european bulbs made by OSRAM. Ph111,112,113 are too long and will cause uneven negative illumination. Either light or dark edges, I forget.

    Last ones I saw for sale recently were at Glenview.com. They are scarce, very scarce, so stock up. I would run a voltage reducer to make them last.

    http://www.glennview.com/


    The closest you can get otherwise is a snowy white 60 or 75 watt domestic, again I forget. Acetone will take off the lettering. Domestic incandescents are going away too, so take action.



    PH 111 will not work if you expect the Leica quality to show.

    The large easel is thicker than the small one so you need to raise the clamping position on the column. There is supposed to be a pin to go thru the holes to make the new position higher up. If you do not have the correct start ( clamping) point, AF will not work perfectly. The clamp height needs to go up around 1/4" for the thicker easel. Use a wooden dowel if you must.

    Set the focus at 10 X, lock it in with one of the two hold downs that slide around the focus mechanism. Then bring down to 3 1/2 X and use the thumb screw
    that sits against the focus cam to establish focus. Then it will work 3.5 to 10 X perfectly. Original Leica Focotars will make up to 8x10, optimized for 5x. After that corners go bad. Later lenses worked better,

    There is also a anti newton slip on "filter" that fits over the condenser. Buy one if you can & it will cost dearly.

    The second clip around the focus barrel is for setting focus point on paper placed directly on the baseboard, no easel.

    The extra bushing may be part of a pair that runs on focus cam. I will check mine.

    The plates may be for holding the easel clamping lever. Mine is a later model and may not have exact same thing.

    You can solve the bulb problem if you get a new bottom housing from a grey one with the egg shaped head. with filter drawer.

    Edit

    My enlargers are white base without easel clamping. The wood base one is long gone. The older one seems not to have any column holes at all, but i modified set up and don`t wish to disturb it.

    The other has the hole and pin, but I have it clamped above for some reason. Been that way way too long to remember why. Again mine works and I do not wish to disturb it.

    The bushing is for the focus cam. Looks like you have a spare.
