looking for a coupling

[Swarfing]

Jonathan you might want to consider allowing the slit to cut the opposite side as well. it allows it to grip much better. Scott if you want one of theses to cover the whole screw (thread as well) then that is not good. You need to take some off to about 12mm which should be about the bottom of the thread, 16mm seems a bit big?

i`m sure you are thinking for a leadscrew??? first post makes it sound like it lol
all i need to do is connect a 14mm motor shaft to a 16mm shaft with a sprocket on it

I did consider it, but my slitting saw is not big enough. When I get a bigger one I'll do that.

It would be helpful to know what it's for. 16mm implies a ballscrew, but 14mm is a bit big for a motor and 80mm is a bit much....perhaps it's for something else?

Edit: Didn't see previous post in time, so it is something else...

the coupling was for a very odd conveyor system i`m fixing
the motor is just a dc motor with 14mm shaft but thats fine if you cant do it not a problem

didnt think the length would be much of a problem (80mm long)

did look on ebay there was a few but not the size i needed
anyway jobs done now made it my self
