I recently purchased a set up block lot of 8 on EBay as I was after one specific block. These two blocks were unfamiliar to me and I can’t figure out exactly what they’re for. Figured I would ask for help ID’ing them.
The dimensions and features of the blocks are:
Block with one hole :
-1.997”x1.994”x1.000”
-1 x 0.500” reamed hole with 5/8” counter bore
-0.125” pin running along the tangent of the hole.
-1/16” pin intersecting the hole perpendicularly halfway.
-0.125” radiused groove almost tangent to the hole.
-surface ground finish
Block with two holes:
-2.000”x1.650”x0.997”
-2 x 0.625” reamed hole with 3/4” counterbore
-0.125” pin running along the tangent of both holes
-surface ground finish
I figured they’re probably for a very specific set up and I won’t ever need them. Maybe I overlooked something though and they serve some purpose I haven’t encountered yet. Thank you for your time.
