Dear all,

I just learned something new. A Rapax lens has a different hole size then copal 0. So I can't use my lens wrench to attach the Rapax lens to the lens board.

How should I attach the Rapax lens to the lens board?

I own a 90mm Wollensak Rapax lens.

You can look around for an Adjustable Lens Spanner Wrench, example:
http://www.skgrimes.com/span/index.htm or
http://www.adorama.com/VWLSW.html?searchinfo=spanner (over priced!)
or set the lens 90 to 120 degrees counter(anti)clockwise of where you want it to be, run the retainer ring up as tight as you can get it, hold the retainer ring stationary with one hand and turn the lens/shutter clockwise with the other until the shutter is tight and in the position you want it to be.
The shutter will not be as tight as if tightened with a wrench but tight enough to be used.
