The cross slide stop for my lathe was lost by the previous owner, and I’d like to replace it.
The hole pattern is 12mm x 30mm as closely as I can measure it. The owner’s manual says it’s secured by two M6 35mm socket head cap screws, and two 6mm x 40mm taper pins.
Matching existing taper pin holes seems challenging. My plan is to:
1) Insert and lightly set the two taper pins. Cut the stop block to that height.
2) *Assume* that the hole pattern is exactly 12mm x 30mm
3) Drill and counterbore for the socket head cap screws (shoulder bolts, maybe?)
4) Drill the taper pin holes at 6mm diameter
5) Hand ream the blocks so that the taper pins sit about 20 thou above flush
6) Mount the block with the screws
7) Use the block like a jig, and hand ream again until the pins are flush
8) Drive the pins home below flush, and stake
Is that likely to work? Is there a better way to match existing taper pin holes? Should I just drill and ream the block pin holes to .250”, use that as a jig, and ream the cross slide out? I could then use .250 dowel pins instead of the 6mm taper pins.
Thanks for any suggestions!
