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!
