Not in front of mine at the moment, but from memory (Andy/others, step in if I get this wrong?)
These sticks aren't really meant to be twistable between straight and diagonal "on the fly." It's an accident (feature?) of the design that allows us to use them that way. If you cinch it down tight, then you can't let it float between straight and diagonal. By not tightening it all the way you get enough play to be able to rotate it "on the fly."
SO: Hand tighten it enough that it isn't swimming, but don't cinch it down if you want quick straight/diagonal switching. I imagine with long-term switching, it will work its way loose and you'll have to tighten it down again, which isn't a big deal imho.
Huh, that would be pretty disappointing, especially since Ultimarc says "Another feature: the switch-plate can be rotated 45 degrees for games such as Q-Bert!"...it doesn't say anything about "it's not REALLY supposed to do this, and you can't easily do it on the fly". Being able to switch between the two is why I bought this stick in the first place!

Also, I don't see that I have the option of "not tightening it all the way" though. If I don't tighten it all the way, it won't line up for the "straight" configuration.
The way that it looks to me is that:
- You can slide the base onto the shaft, which will line it up for a "straight configuration", but the base would/could slide right back off the shaft.
- You can rotate the base 45 degrees, which will give you the "diagonal configuration" (for Q*Bert, Congo Bongo, etc.). The base is on decently solid (it at least won't just rotate right off of the shaft anyway), but this 45 degree rotation is as far as you can rotate it without applying a good deal of force and cranking on it.
- You can rotate it another 45 degrees (for a total of 90 degrees from the start point, where the base just slid onto the shaft) if you apply some force and crank on it and get it to "lock" into place into the "straight configuration". Unfortunately, you can't easily rotate the plate back 45 degrees to go back into the "diagonal configuration" unless you apply a good amount of force and "unlock" it.
Sorry to be a pest about this, but I just want to make sure that I'm seeing this correctly. Is this correct?
There was a big thread about this not too long ago with pictures and discussion.... should pop up in a search
I know which thread you're talking about (1UP supplied the pictures), but that only dealt with how to switch between "straight" and "diagonal"...he didn't really get into how to attach the base. 1UP, are you out there??
