RAPAS attachment issue with new 1600 mount


Mike Cadwell
 

Hello All,
I am having an issue with attaching a RAPAS to my 1600 mount.
In the photo below you can see the Alignment holes for the RAPAS at 12 and 6 o'clock.
However, there is also the end of a silver colored screw protruding from the backplate of the mount between the two Alignment holes.
This protrusion sticks out about 1 mm and does not allow the RAPAS to seat flush with the mount backplate.
It is not a button screw and there is no way to remove it with allen wrenches or pliers.
I don't think this should be there and I'm thinking that I could grind it down flat with a Dremel to smooth out the surface.
I know this will mar the surface but that's okay.
But, wanted to make sure this should not be there before proceeding.
Any other ideas would be much appreciated!

Thanks, MikeC.

That screw holds an interconnect board to the inside of the back plate. Just remove 3 screw that hold the back plate on the axis, unscrew the screw, put a washer under it and screw it back on (or use a shorter screw). It may be that the assembler forgot to put a washer under it - I will check on Tuesday when people return to the factory. I would not use a Dremel to shorten it. Don't worry about removing that back plate - there is nothing critical back there.
