A beef with my enlarger

[Thomas Bertilsson]

I have an Omega ProLab 4x5 enlarger. Overall I'm happy with it. I've tried using levels and whatever else I have in the house to get it fairly well aligned. I got most of it right.
Now to the problem. The lens turret on this enlarger only seems to accept the original cheap lenses. They're not bad, but I'd like to stick my Nikkor 50mm and Schneider Componon 80mm on the turret somehow, or they just collect dust, and deprive me of extracting the maximum out of the prints.
However, when I mount these lenses onto the little flanges and put them back in, the turret will not accept them because the backwards extended lens barrels get in the way. Any idea what can be done about this?
A friend just recently made me an offer for a Beseler 45 and I'm very, very tempted. But I also don't want to go through the whole set-up procedure again... Throw me a bone if you have it! Please with sugar on top.

I know absolutely nothing about this enlarger, but if you want a lens with an M39 thread not to project so much out of the rear of a panel, I would look for some cheap (Russian) LTM extension tubes and interpose one of suitable thickness to make your lens stick out more!

David

Thank you David, I'll check it out. If it's cheap I can probably buy it even if it doesn't work out. For a while I thought about having an adapter machined. This may be the better option.

Hi Thomas, is it the Prolab (D5 chassis) or the ProlabII (D5500 chassis) that you have?

[Thomas Bertilsson]

Hi Dinesh,

I'm pretty sure it's the D5 chassis on it. The front of the condenser box says ProLab 4x5 on it. Not ProLab II. Does that help?

Hi Thomas:

I have a lathe and a small milling machine. I'm sure we can build you some adapters.

George,

or maybe I should just buy that Beseler from you...

Hi, can the turret be removed and just use a lensboard?

Jon

ps I do have a 10mm extension tube around here somewhere if you want it. It came on a 63mm El Nikkor I had.

[gminerich]

I take trade-ins too!

Its probally just as easy to pull the turret off and bring it and your lenses to my house or maybe we can make a new lens board. Your choice.

Jon, pm sent.

George, I may have to take you up on your offer. Let's chat about it.
