Stepper mounting on an EQ3 RA Axis...advice needed please

[dazzystar]

Hi All,

Having completed my OnStep EQ3 upgrade I'm not happy with the stepper mounting on the RA axis as there's only one mounting hole on the body of the mount and although the 3D printed mounting bracket seems to hold I can't see it holding well for long. Has anyone any thoughts on something that would be better?

Cheers
Daz

Just googled the topic and found the following video which suggests this is the "normal" method of attaching the motors as it too uses just one bolt.   Not sure if someone has come up with an alternative, but seeing the project is open source I would have assumed someone would have produced new brackets if the existing ones are not up to the task ? 

Maybe google thingyverse (sp) to see if anyone has any better bracket design ?

Same for the Eq5 mount only 1 mounting hole for the plate alebeit it does have a wedge to locate the plate in a groove on the mount as per Malc look for a better support. that has some lateral play to take up the slack in the belt. maybe bring out the metalwork skills and make up a bottom plate out of aluminium.
