Re: [CAD_CAM_EDM_DRO] Re: Souces of Timing/Drive Pulleys

Tim and Hugh -

Thanks for the reply's. I will probably go ahead with
the XL pulleys' and bore out the hubs. I am also going to
look at the taper-loc hub to see if these would work
with these somewhat small pulleys. Just seems like it
would be better than a couple of set screws.

Thanks again

Mike
