Universal Coupling

[googlinggoogler@hotmail.com]

Hiya,

When I used to make model boats years ago I would use a universal joint
/ coupling on the prop shaft.

Im trying to locate some relativly cheap univeral couplings, but not
for a model boat, however the ones i used to use would be ideal.

Can anyone suggest a place in the UK that sells them relativly cheaply
as I need to purchase around 8 and dont want to spend a great deal more
than =A315 for the lot. They need only have an internal diameter of
around 6mm, and can be made of plastic also I would like them to have
some form of grub screw for tightening up.

Can anyone recommend an online shop in the UK for purchasing this type
of thing?=20

Thanks

David
