I have seem quite a few shutter ruined by ply wood lens boards. Its a shame when its a really good lens mounted in a Ilex #5 shutter that was improperly mounted on ply wood.
If you insist on using ply wood lens boards the best thing to do is mount the lens with a heavy duty flange that is screwed on to the board. If the board decide it is going to warp it will pull the screws out and the shutter will survive.
