Hello all Mono builders
Did a trial assembly of the landing gear frame and swinging arm bits today and encountered a few problems:
1. The swinging arm is not in the centre of the landing gear frame. It is not out by much, 5mm more one side than the other but it is enough to cause the swinging arm to hit the LG frame. The relation of the arm to the LG frame is dictated by the welding of the vertical tubes and there is no sideways adjustment possible.
2. The big pin LG04 that secures the block assembly to the swinging arm is a nice fit and free to rotate in the bushes of the bottom plate LG07 until I adjust the two plates to the correct dimension of 79mm. This must bend the plates slightly because the pin then becomes tight in the bushes and instead rotates within the un-bushed holes of the aluminium swinging arm. I find it strange that the holes in the arm have no bushes especially as there is no mechanism to stop rotation of the pin.
I am not too worried about 1. The arm is only 2.5mm off centre and it is to the port side so will give a fraction of extra clearance for the brake cylinder and I can extend the cut away part of the arm to clear the frame.
Has anyone else encountered the LG04 pin locking up in the lower plate. I would prefer to see some similar bushes fitted to the swinging arm to prevent wear of the aluminium.

In my case I fabricated a little right angle plate that was welded to one
end of the pin so when the pin was installed the angle fitted snugly over
the top edge of the Landing gear frame stopping it from rotating, normal
washer and split pin at the
other end.
