hi,
I finally finished installing the belt kit on my neq6 yesterday and gave it a test run.
its a lot quieter and responsive and going by the pec data captured after the mod, its a huge improvement over the previous 30 arc sec PE.
the improvement could be the worm mesh adjustment as well that I did from scratch.
I took a few days for the mod, cleaned out all the bearings, adjusted the worm mesh after a lot of trial and error, and that has paid off. any imbalance shows up as the axes rotate more freely.
I captured this PE data with a star at the meridian through thin clouds.
couple of gotchas with the mod. when inserting the RA worm wheel into the body, you need to insert it as straight as possible. I tried it with the body fixed on the tripod as per Rowan's instructions, but I didn't insert it straight and it got wedged solid. took me half a day to get out. no damage though.
I then inserted it with the body vertical, and that went a lot easier.
that tip to use the plastic sheet with the allen key for the motors was brilliant.
couple of minor things,
when installing the worm end covers, tightening them causes the shaft to bind a bit. so I installed the cover first and then inserted the shaft and bearing and that helped as I could adjust the nut at the other end.
need to keep the timing pulley loose on the shaft before inserting, else it won't go in.
I was following the instructions step by step, and there is a warning early on to watch out for the thrust bearing accidentally falling. that needs to be one step earlier cause I read it after the bearing fell :-)
Overall pretty happy, and will post some results for repeated slews and target centering.
Cheers
Alistair
