Full disclosure: I'm still waiting to purchase a router, but since I did get a set of bits, I've been goofing around in Sketchup, designing a router table that, I think, should suit my immediate needs. And just in case anyone else might be interested, I thought I'd share it here.
Some of the components are approximations: I used real measurements when I could find any, but for other things, I just guessed. (I created all the elements in this file: feel free to reuse if any of them will suit your goals!) Because I couldn't find dimensions for featherboards, the power switch I'm considering, and a few other items, I just didn't bother modeling them.
The table surface is currently just modeled as a 3/4" chunk of MDF or melamine or whatever, because I got tired of accounting for laminate thickness
The underside is spaced to accommodate a pair of 2x4s for "mounting" across a pair of saw horses, if necessary (or desired).
When I a) get my router, and b) get a dispensation from my wife to start accumulating parts, I hope to turn this virtual model into a physical specimen.
Not entirely sure if this post is relevant (I'm still new here!), but it's a Sketchup model, and it's a router table, so it seemed to fit!
