Aristo Cold light head

FM2N · Mar 25, 2010

Hello All,
Does anyone have a picture of this head on an Omega D2?
For the life of me I cannot figure it out and 1 pic will be worth a thousand words.
Thanks

I believe it goes in place of the condensers in the can.

I know where it goes but I could not get it to lay flat. I am not getting something and a pic would help.

Thats how mine fit.carefully take the two lens out of the aluminum casing and slip the cold lit in and feed the wires up threw the head support casting.You have to take off the top light bulb casting off completely so the wires can come threw.

I have an Aristo fitted to my old D2 but I don't have time to photograph it right now. If no one else has supplied you with a photograph by this afternoon, send me a PM and I'll shoot one and send it to you.

Ok I understand that part but when I remove the light bulb housing I have the 2 arms, left and right, that a bracket that came with the new unit fits into and attaches to the unit but when attached it does not swing down into place correctly over where you would place the negative carrier. Also while I have you do the filters fir in the draw that pulls out of the cold head? Are they a special size?
Thanks

FM2N, took some d----l Picks of my set up,will down load them when my daughter gets back later on to day (ain't no good with computer stuff).One thing that might be wrong is the bracket for the cold lamp might be for the Bessler enlarger.On the Omegas the cold light just slips into the round aluminum condenser houseing and that attaches to the regular Omega head casting with the two arms on each side,the top light bulb casting is not used.I will try to down load the pic's I took but don't hold your breath.Wish I could help more.

The cold light fits in place of the condensers and corrigated collar.

The light housing and all else is removed except for the piece with the arms that the aluminum collar boyonets into.

The position of the collar is the same as before. The same arms lift just as before. If not flat on the neg carrier, loosen the 4 thumb screws , let it settle, then retighten.

The arms are supposed to fit in the recess between the threads of the screw and the head so they pivot. If you don`t get this right, the collar will not sit flat and will not stay level as you raise and lower.

Put filters above the neg carrier and below the light or under the lens. Both work ok

what you do is take the piece with the bulb off,
and then take out the magnifiers ( condensers ) and ring
they are in a metal ring ...
take the opaque disk and put it in first ...
and put the cold light head on top of the disk
it doesn't lay flush it just sits in there on top of the disk.

the wires run down the column ..
on mine at least, it doesn't look pretty, but it works ...

good luck!
