The filter rod was also used to hold the shutter.

This one has provisions for two rods, each about 1" from the edge of the
lens, extending down as far as one wants to make a rod. I'm a little
concerned that shutter movement will cause vibration shake, however subtle,
so I might mount the shutter from a sliding arrangement on the mail column,
which just cannot possibly move. (750 pounds of it). Two more rods can be
added with simple drilling and tapping. So much real-estate on this thing!

You probably need a five foot ladder to go along with the enlarger.

Heh! I have a vision of Watson on the ladder, "Mr. Holmes, is it correct
now, Sir?"

Saltzman also made a very heavy, geared, tilting baseboard for
perspective correction. I've only seen pictures of these.

Over the years of building things like Harleys

and rebuilding VWs http://www.digoliardi.net/58.jpg ,
http://www.digoliardi.net/bug_n_brad.jpg has made me comfortable with making
large things. A geared baseboard would be simple. But the demand for such a
thing is a market of One!
