Put the countertop on the base, put the MDF on top of the countertop, and line up the marks you drew on each end of the MDF with the countertop below it. When you have it lined up, clamp things down, and route the edge of the MDF using a 1-1/2" or longer flush-trim bit, with the depth adjusted so the bearing rides on the countertop. I clamped a couple of scraps of doubled MDF at each end to give the router base something extra to ride on at the ends.
I like the idea of re-inventing the wheel. I choose to believe that while others may have considered these improvements, they just never got around to trying them out. Brain gets bored with status quo. So, I try to keep Brain happy with the occasional foray into uncharted territory. And I must say Brain has had some really good results. Thanks, in part, to you, and the Roy. You never know where a good idea might come from so I’ll check in once in a while. That and make sure to build it in Sketchup first.
There are simple jigs like a trammel baseplate and T-square, but you’ll also find a vacuum-clamping jig you can use to rout surfaces without clamps getting in the way, a dowel-making fixture, and router jigs to help you make fluted columns and even flamed finials. Bill also included several variations of router tables, including an ultimate table I built for my own shop.
This bench suffers from no such limitations as it provides an incredibly solid and stable workspace, albeit in a somewhat stripped down version. In terms of performance, Sjobergs tops our list at providing 80 lbs of weight capacity. This is one of the more quantifiable measurements to determine the quality of a work bench’s craftsmanship. This is achieved by using thick pieces of European birch wood and working it without using lower end joints – like butt joints.
