Thanks guys. Found a place in Smeaton Grange not far from me that had grub screws M2x0.4 - 5mm and 3mm. That did the job nicely. Also ordered some SS from small parts in QLD, but I might receive them after the SPSP. I had to add some grub screws to the gearbox couplers on my G11. When I changed the worms to the one block ones the couplers changed from the old oldham model to new articulated/spring loaded ones. Problem is that they clamp on the shafts as the old ones were locked on the flat face of the gearbox shaft. As temperature dropped I found myself losing dec or even RA when guiding. The new high torque motors just kept going, no stalls, slipping over the shafts.
