That is a beautiful base that you have made, Rob. I have a tip for you, or others thinking about making this. For probably close to 10 years, I have been meaning to write a magazine article about this, but I never get around to because writing for magazines doesn't pay very well. So I'm just going to go ahead and throw it out there for others to use.
When I create router bit holders, I like to organize my bits according to profile. So for example, I want all of my ogee bits of different sizes in the same area. The problem is that some cutters are 1/4" shank and some are 1/2" shank. So I want to be able to organize my bits regardless what size shank they have.
The solution that I came up with about 17 years ago was to drill concentric holes of 1/4" and 1/2" in the same location. This way, either size bit can be stored in the same location.
1) Lay out a grid for the hole pattern. The grid can be variable distance between holes. So for example, the area where straight cutters could have a tighter spacing, and the area for ogee profiles could be wider.
2) Using a 1/2" forstner bit, drill a 1/2" bore, down 3/8" (deep). You drill the larger bore first, because the pilot tip of the forstner bit will leave a pilot hole for the smaller bit to follow.
3) Using a 1/4" forstner bit, drill a 1/4" bore, down 3/4" (deep). Use the pilot created by the 1/2" bit for centering.
