Can you tell us more about the couplers you use?
I've no experience with couplers, but I thought that the whole point was that they allowed for some mis-alignment between the screwthread and the motor?
Would some PTFE tape around the threaded rod before you clamp it in the coupler help to centre it?
I've got an interest in this because at some point I'd like to replace my hosepipe and jubilee-clip 'couplers' with some real ones!
If they need accuracy to within tenths of a millimetre, then I'll need a rethink.
(Perhaps I could join the screwthread and motor together with one of those flexible drill extensions?! :heehee: )
Keith.
