pic: BWD-101 machined part

This is the block that makes up the bulk of BWD-101. It is reversible such that it can be configured to act as a flat belt clamp or a round belt clamp, without losing the ability to tighten it down with 8-32 screws. The small flat part near the pivot holes allows the use of a 1/4"-20 nut to be placed there for pulling clamps closer together without a wrench.
