Re: [CAD_CAM_EDM_DRO] Re: HTD belts vs GT2 on Bridgeport

It is always a good idea to bore a pulley out to size if you want
accuracy. Often the supplied bore is quite a long way out. With flanged
pulleys it is a bit of a drag turning up a fixture so you can hold them
in the chuck but it is worth doing.
