Need help with mounting my enlarger lens

[timbo10ca]

I bought a Super Chromega E last September. I want to use it for 5x7 negs, but it came with a 150mm lens. I found a 210 Componon (non-S) on ebay cheap so I bought it. I then realized I needed a larger mounting cone than the one I have for the 150mm lens. Plus a lens disc and flange. I had no idea what I was getting into. So I found a place that could manufacture these 3 items for me. I'm still waiting, and am doubtful it'll ever happen. I found the cone at B&H, but by special order only (pay now, no refunds). They don't have a lens disc large enough, but they have a blank one (also special order) I could get a machinist to cut for me. They have no flanges at all, and I can't find one anywhere. A post on here, and careful measuring with a ruler (I don't have calipers) determined that my lens has a 60mm thread. I'm wondering if I could get a 60 to 67mm stepping ring used for filters and use that as my flange/retaining ring. Any input would be *much* appreciated on how I might get this to work. I've been staring at this thing for 6 months and really want to use it, but I'm in a little over my head and parts are as rare as an honest politician.

Thanks,
Tim

Tim, have you tried contacting http://www.khbphotografix.com/? They have many parts for the Omega and appear to do custom mounting.

That's who has been working on this stuff for the past 6 months.

Haeve you contacted Harry Taylor? He was very helpful when I needed a 150mm cone for my D-3. http://www.classic-enlargers.com/

Tried him- he didn't have anything for E enlarger

Yes the stepping rings work and if you find one that fits your lens then get another and use it as a lock nut.

A little hard to know without knowing what the lens looks like. Is it like this?



I have some ideas but I would like some additional info.
Your existing cone is too short so you need the 421-174 6-1/8" Cone right?
The lens plate for that cone and your lens is discontinued (421-024 For 210mm Componon-S) right?
An un-drilled lens plate is available (421-000 Flat Blank Lens Disc)?
You have no retaining ring for the lens?

What I would do is buy the 421-174 cone and blank disk. Send the disk and lens to SK Grimes. They did some work for me, so just a guess at the price, but perhaps $20 for the hole in the disk and $60 to machine a retaining ring.

No, that's not my lens- it's "non-S". That's the cone I need though. Good idea on SK Grimes- Thanks.

Ok.
From what I can tell, because of that short bellows, it really is not a "5x7 Enlarger" without that cone .


I'd be very, very glad the cone is still available anywhere, and would not hesitate to order that part as soon as possible, before it becomes totally unavailable!

That disk should not be a problem. In fact, here is a disk that did not sell at $9.00 so, I'd try and contact him. Once you have that disk, send it and the lens off to SK Grimes. http://cgi.ebay.com/ws/eBayISAPI.dll...701&SID=p12d2i

If you can't get a disk, you may need to wait until the cone comes in to get the dimensions for those two mounting holes so SK Grimes can make one for you. It looks like just a round piece of metal.

Hopefully you will get the lens back the same time the cone comes in.

Can I use that disc on the "E" enlarger? It's for a D-2.
