Extra low profile milling clamps

[WmRMeyers]

I'm really surprised and very much appreciate the number of 'thank you's' I received and which are still coming in.
Thanks to YOU guys!

You met a need a bunch of us have. More than one, really. Versatile hold-down, Check! Low profile, Check. Doesn't eat a lot of table space, Check! Easy to make without a fully equipped shop, Check!

Of course we like it!

Thanks Bill, there are already some thoughts for modification that you or who-else might have, by now, considered.
Like, adding springs for holding up the tips for easy reach but it would defy the object of keeping them out of the way and the secondly some strip or shoe to protect the bottom of the T-slot from damage.
Truth is, clamps like those will only be needed for special conditions. Not your everyday run of the mill utensil.
Much appreciated!

Agreed on hold-open springs; counterbores for those will reduce material needed for clamp bolt recess, or threads in the nut.
But a flat leaf or wire torsion spring won't. . .

Holding thin stuff for machining is always a challenge. This morning I needed to mill some 3 mm polycarbonate. The cutting forces being a lot less than the steel plate used as an example in this post, that enabled me to use a simple vacuum chuck that I made for PCB milling.

ARe the 8mm set screws to hold the jig in place pushing up on the T-slot?

I just tried it and it worked perfectly. It is easy to miss. The PDF is under the very last row of pics on the left side.
