Failed Bearings

Last few times I've been out, my guiding has been terrible. I put it down to bad seeing and the jet stream overhead at a whopping 54 m/s. Even so, the guiding was far worse than even with those conditions. I decided to strip my mount down, initially I couldn't see anything out of the ordinary, until, I started turned the RA worm screw by hand. It was jerking as I rotated it. I stripped the worm gear down completely, upon inspection one of the RA bearings had failed, it wasn't seized, but making a click, click noise. This would obviously degraded any guiding, so I just ordered a pair of high quality SKF 628's at 10 euro each.

Cheap nasty bearing never did anyone any good. SKF are decent.

 

That's true. Soon as I changed them the guiding improved dramatically. It might just need a little tweak on the adjustment screws to get it perfect.
