Re: [CAD_CAM_EDM_DRO] helical couplings

Alex,
You might also think about using a "spider" type coupling, instead of
the helical. Then you can buy one end of one size, and the second end at the
other size. Then the rubber "spider" fits between. You still mave have to
bore one end to fit. These are available at www.mcmaster.com
