Better V-block clamps

[Toolmaker51]

Marv;
Full agreement on cast style clamps. Once in awhile, needing to orient 90 from initial position, a less than perfect solution is perch twixt ground blocks. Your concept certainly answers the height issue. Commercial manufacturers tend to proprietary threads, preventing subbing a short set or cap screw. My treasured old Taft-Pierce's, the only bridge style worth their height still convert to flat strap when needed.
<*>*^$@:-)! That's the triumphant rage smilie [pun intended] who drills and taps next size up - usually fine thread metric!
