I'm pretty certain I haven't cross-threaded it, it's sitting flush against the mount.You may have cross-threaded the lens and mount.
Before you lose patients and damage the lens or the mount or both, do yourself a favor and buy two strap wrenches and you'll be happy you did. These work so slick you'll wonder how you ever got along without them. Where I live there are some home supply and tools stores that sell them cheap, but they can be worth their weight in gold at times. This sounds like one of those times for you?
Well, you can do whatever you wish, but I'd still get the little strap-wrenches and use them. The little preset lever you talk about is not a problem. It is held on with one small screw right through the middle. Just remove the screw and take the lever off while you use the strap wrench. When finished just put the lever back on. I'm just trying to help you avoid kicking yourself in the behind later on 'cause you buggered up the lens. Hey, I been there and have the T-shirt to prove it. Actually a whole drawer of T-shirts.I'm pretty certain I haven't cross-threaded it, it's sitting flush against the mount.
Unfortunately the lens has an aperture lever/switch which isn't pictured which would prevent being able to put a strap on it.
Or you could just spend 30 bucks and buy another lens . At this point you got nothing to lose strap wrenches are great . Chain wrenches are even betterWell, you can do whatever you wish, but I'd still get the little strap-wrenches and use them. The little preset lever you talk about is not a problem.

Maybe put 2 drops of liquid wrench on the threads and walk away for a couple days . You might try a little heat , blow dryer not torch .
It's just threaded into the lens cone. No retaining ring.You may need a spanner to remove the retaining ring from the rear of the lens, inside the cup of the plate.
You are turning in the correct direction, true? (which would be to the left).
A silly and trivial question, but it occasionally trips everyone up.
Presumably the lens needed only slight force in threading it in? Did it run smoothly with each revolution?
You are sure that the threads on both the lens and the mount were in good condition? Was a lens mounted in the board previously?
Heat may help, but I'm not sure what the best way to get the board hot without affecting the lens. Do you have a soldering iron? Perhaps a clothing iron?
