Re: [CAD_CAM_EDM_DRO] Motor Couplers

Dave,
there is a coupling I have found at most farm type stores, made by Lovejoy,
see
http://www.grainger.com/Grainger/productdetail.jsp?xi=xi&ItemId=1611775840&ccitem=
for an example, there are 3 different spiders you can use, depending on
alignment and/or stiffness required.
total cost is less than $10 for a complete coupler in smaller sizes.
