Small motor coupling sourcing

depends how critical the application is, I have used rubber or neoprene hose and clips in the past.

F Murtz Inscribed thus:

I was going to suggest reinforced rubber gas pipe. :-) I've done this a number of times with good results. A spot of washing up liquid helps if its bore is a bit tight...

A quick google suggests a suitable shaft coupler runs about %4.00 plus a little fright getting cheaper in volume , lab style heavy wall rubber hose works a treat (clarks)

Yeah, it's always the fright that gets you :-)

Try These guys,

That's the approach Codan have been using on their autotune antennae for donkeys' years.

Cheers guys - rubber hose is what I'll be using initially. Longer term I wanted something I can install & forget about.

Minibearings, I'd fogotten about them. Thanks I'll check them out.

Looks like I'll be using that approach initially. It for a small CNC router so the torque & usage may be a bit higher than Codans application.

I'll see whats in the junk box vacuum hose or small pwr steer hose should handle a bit of torque. thanks

My home made auto antenna tuner was manual before the mods and had hose on it a decade before it perished and failed , no clips just hose "(thick red rubber)

Well usually there are some at your local hamfest , the goldcoast club is a week or two away

I'm out west - bit far to travel!
