Re: [CAD_CAM_EDM_DRO] Looking for Coupler

I used a heavier but similar design (stainless steel bellows coupling) from RW couplings for my rotary table,. They are great, but two caveats. The first is the $60 price tag, the second is that you need thrust bearings on the item you are coupled to, the bellows are not rigid along the primary axis (think of it like a flex straw).

These are great for instrument dials and very light loads that have
large misalignments or where one shaft moves on an angle with
respect to the other. They are made by CNC machining an aluminum
mandrel, copper plating it, then etching away all the aluminum, and
plating both sides of the copper foil with nickel. We used them
for bellows on a container of liquid neutron detector material.
