P3D How to Rotate chips in RBT Mounts

With reference to the discussion on rotating the chips in RBT mounts (Mark
Kernes & Larry Berlin, etc, etc), The following may be of interest.

I found that I needed to slightly rotate one chip in a series of aerial
hypers.

This is the procedure that I used:

1. Fix the first chip in the normal way
2. For the other chip, cut an RBT pin bar into three so that there is one
chip pin on each "mini pin bar"
3. Use two  "mini pin bars" for the chip that needs to be rotated - turn the
"mini pin bar" and/or have one on the top rail and one on the bottom rail to
get the required rotation. (Normal pin bars allow adjustments of up to 0.4mm
in 0.1mm increments.)
4. I found it easier to use the alternative pin bars that allow adjustments
in approximately 0.2mm increments to a total of 0.7mm.

The procedure worked perfectly. Once I had done a couple I found that the
procedure was quick and worked well. I found it best to make any height
adjustment with the chip that was not rotated.

This procedure only works for small rotations. If large rotations are
required, as can sometimes occur with aerial hypers, I then use the 20mm
high Spicer cardboard mounts.
