I built a darkroom a couple of years ago after having my interest in B&W
revived, and I dug out my old B-22 from my college days.  It had been in the
original carton all this time.  The grease on the counterweight spring strap
had solidified and the metal strap brokw, but I obtained a replacement from
"Classic Enlargers."

The B-22 that I bought came with both  35mm and  2 1/4 x 2 1/4" glassless
negative carrier, and it had a supplemental condenser and a 70mm enlarging
lens for use with the 2 1/4 x 2 14 setup.

I updated the enlarger with a cold light head, so the condensers are not in
use right now, but all original parts are being saved in case a museum wants
it after I shuffle off!

Along the way I have acquired a Russian Horizon 202 panoramic camera.  It
does a pretty good job and is fun to use, but it produces a negative the
same width as a 35mm, but 1.5 times as long (24 x 54 as I recall).  I bought
a B-22 35mm carrier on e-bay and had a local machine shop recut the window
to the correct dimensions.  I use a 70mm enlargging lens (same as for a 2
1/4 x 2/14).  I don't remember the price, but I'm thinking in the
neighborhood of $20 - 25.

As for stability, my B-22 is bolted to the counter.  I "sandwiched" the
counter top between 2 foot lengths of hardwood 2x6 above and below the
counter, and the enlarger column is tightly screwed through the whole
assembly.  Not a lot of shake left it it, but I still wait for things to
settle down before exposing and try to keep my hands off the counter while
exposing.  I have heard (and seen) of folks who added braces from the top of
the enlarger column to the wall.  My counters and cabinets are heavy and
bolted to a concrete floor and wall in the basement, so they are completely
rigid.  I therefore didn't bother with a top brace, but it woudn't be a bad
idea to consider.

If I were to buy another B&W enlarger, there are plenty of old dichro color
enlargers available cheap, and once the filter numbers are found out and
dialed in, it is possible to change contrasts using B&W variable contrast
paper without having to retest for exposure times.  I'd love that!

But all in all, the Omega B-22 has produced a lot of great photos and is
worthy of some TLC.  It is a classic and easy to work with.
