Re: [CAD_CAM_EDM_DRO] Re: BOSS to servo's and reduction

Hi Scott,

Boring the pulley out should work. I have done it before and used two
grub screws at 90 degrees to hold the pulley. If you are worried about
it coming loose then a small amount of ordinary loctite thread locker
will hold it firmly in place. It will still be removeable with the
application of a bit of heat to soften the loctite.
