Issues mounting Nikkor-w 300/5.6 in Toyo field lensboard

[grey]

The Toyo AX has a maximum extension of 321mm without using the extension back and a 300mm F9 Nikkor-M works fine with a flat lensboard. Unless the spacer and screws solves the problems, I'd get a new board and have it drilled-out for a copal 3 lens. Toyo only made 0 and 1 LB's for the field.

Actually that lens is on the heavy side for a field camera. The 300M would be a better choice but since you have it...

It IS a heavy beast! If I can't get this board to work, I'm going to go the route you suggest - having one modified for Copal 3 shutter.

You might also want to look into a "Top Hat" lensboard that would give you a couple extra inches of overall bellows draw in effect. They should be available to fit the Toyo and handle a Copal 3 shutter.

Just get a new board. Keep that one for some other project.

I have Toyo No. 3 boards for my AX.
