Description
Shooting the breeze in the shop one day, we got on the subject of two-bit sets.
That’s not some pejorative for inexpensive or poorly made TVs but, literally, two atching router bitsthat create mating joints, such as tongue-and-groove, drop-leaf (rule), or cope-and-stick joints.
In orderto get a precise fit, both bits need to be setupperfectly andtestjoints cut. Noproblem, but if you have only one router, you lose the setting of the first bit when you remove it to install the second bit.
In most cases, you can use a sample of the second cut to reset the first bit, butit’s not 100 percentreliable.
And if you have to re-make one more joint after you’re done, you have to start all over again.
The ideal solution would be two routerables, onewith each bitinstalled, butwho has room in theirshop fortwo tables? Or…what if you could mount two routers in one table? It wouldn’t have to be much largerthan a typical routertable, if you did itright.
So that’s what we did John Olson’s design, includes two fences for bit t sets that benefit from that, such as raised-panel or plywood edging sets.
As John was finishing up the design work on the double router table, he realized he could go one better by installing a trim router in one end of the table to give that shop real estate even more value.
Install a round-over, chamfer, or ogee bit,setit, andforgetit—itwill always be at the ready for your most common edge-routing tasks.
