Thank you so much, Matt!
What clamps are those? got a link? They look awesome
Take a look at Carbide 3D Tiger Claw Clamps, bit pricey but it is what I use 90% of the time for my workholding.

A question for folks who put dog-holes through the MDF pieces of a QCW spoil board: Did you space them at 8.75" in either or both axes? Folks who’ve posted about their spoil boards (not QCW) usually choose smaller distances between holes, but the T-track in the QCW will affect that.
Another choice might be to use the common 6" distance in the Y-direction, and 8.75" in the X. I think that with a T-track in place (which usually meets my needs) the role for dog-holes will be to secure sacrificial boards. I can use arrays of threaded inserts in those, which is much less intimidating than trying to access my “screw from below” QCW slats. In the case of using sacrificial boards, the ability to rotate 90 degrees should matter far less.
The spoilboard redesign i’m working on now for my JM QCW will use a symmetrical spacing pattern based on 48" / 5 panels / 3 subdivisions = 3.2" spacing. this way fixtures can be used horizontally or vertically across divisions, and can also be used to help align sections when affixing new ones to the frame.
I did a bunch of work on the spacing of my spoilboard to ensure that everything lined up on the 90 and the 45. Not that it was going to do all that a Festool MFT could do, but I wanted it compatible so the worksurface could be used in a variety of ways including non-cnc. That said I opted for dog holes and threaded inserts and have the t-track from the QCW. Here is the post/file
Since I finished that I have been exploring vac holddown with a Fein Turbo 2 and have been pleased with the results for quick swap of materials.
