Here is an idea, flip it arround. Laser in the other hole.
The other hole is even bigger.
Looks like you have at least a 1/4" of play on those bottom screws...they don't tighten anymore ???
I can't get them to. I think the problem is that since both the top and bottom halves are threaded as the screws go through they don't actually tighten up in between if that makes any sense. Normally stuff like this would have a machine screw and a washer to help bring the two halves closer together instead.
Can you put something like a piece of shrinkwrap or electrical tape on the laser so it will tighten down?
While I was at work I thought about using painter's tape for this same effect. I'll try that and see if it works.
Oh, also, make sure the threaded part of the hole is opposite to where the head of the screw is. In other words make sure the screw is not screwed in form the wrong side.
I put them in how the instructions said, but I tried it the other way just for kicks and giggles, still no love.
Oh, by the way Bushman it's 1.3cm in diameter.
Thanks for the tips guys.
