Finally spent a substantial amount of time to figure out why my lockdown bar is so insanely tight!! Both adjustment screws have been all the way up since day one but there's times when I almost can't get the game open or buttoned back up. Started to worry me.
I compared the lockdown mechanism mounting position to other games and measured lockdown bar with calipers to compare to other lockdown bars. Everything seemed to check out.
It was pretty apparent that the lock slide was hitting too low on the chamfered hooks to engage.
When the pf is in the down position the pf hangers hit the lockdown bar's two 90deg bent tabs and hold the lockdown bar way too high to engage. I ground off between 1/16" and 1/8" on these tabs where they come into contact with the pf hangers. I also ground the two chamfers a little larger. I moved the beer tape up against the two tabs so it wouldn't press up so much on the lockdown bar being on the bend, and that's also where it was located on my other bars.
Now, everything is working as it should. Even screwed the two lockdown mechanism adjustment screws down a tiny bit to fine tune the tightness on the lockdown bar in the closed position.
