Hi all
The cross-head guide for my vertical single requires slots in the sides parallel to the axis of the bore (as well as letting you see the cross-head go up and down, these would allow removing the pin that secures the connecting rod to the cross head). The only tool I have that is the right size is a piloted counter-bore, so I'm thinking that I could drill pilot holes, counter-bore the beginning and end of the slot, and clean up with a smaller end mill. In order for this to work, I would have to leave boring the the guide till after this operation in order to have some meat there for my pilot holes. This will leave me with an interrupted cut when I bore: is this likely to be a problem? (The part is brass).
Thanks
Joe
