I woulda added some c-clamps, but I would have had to walk to fetch them, which would have ruined the moment.
What was I clamping?
For personal use, I make cup coasters that are as thin as I can make them and about 6” x 6” so I can plunk a cup down on them without really looking: big target and if I miss and set cup on edge of coaster, the cup won’t tip over.
I was clamping two very thin pieces of wood with grain oriented 90 deg (ie, home made two ply plywood).
Future plans include metal plates on bottom of cups and coasters with powerful embedded rare earth magnets to actually suck the cup into position. Progress marches on….
