Lalai and I went to Punggai, Malaysia, last 7th - 9th August, with the SingAstro folks. The first day was a bust due to clouds, but the second day was quite OK. I just had a lot of problems with my Vixen Great Polaris with Autostar refit. The most annoying was the tendency of the Oldham couplers to slip, which caused loss of tracking. But the killer bug was the C9.25 OTA colliding with the motor bracket when pointed at Lyra (basically to the North-East, above a certain altitude).
I used a 6mm bolt (with the head cut off) as replacement motor shaft. From left to right, the rod end bearing (self-aligning); timing belt pulley with two set-screws; and the Meade plastic gear.
Here's what it looks like on the motor:
I fabricated some new aluminum brackets for the motors, and screwed these brackets to plywood scrap.
Close-up of the RA axis:
and the DEC axis:
It ended up really easy to mount the rod end bearing to the aluminum plate, as the bearing had an M6 bolt as part of it; a simple wing-nut held it in place.
