I wish I could take credit for this great Morise Jig but I Can't ,this great jig is Bob & Ricks way of putting in Morise, My Heros
, I have used the box jig like yours b/4 I saw how Bob and Rick did it and it blew my mind how neat it was and easy it is, as you know most stock is not always true,(5/8" to 13/16" thick) it can be off just a bit and this will put the slot off just a bit but with Bob and Ricks jig it will always be right on the button,dead center of the stock.
Plus if you want the slot off to one side of a leg it just takes a spacer in the jig to move the bit over to one side or the other of the leg for a apron part of the table, it's a great jig that Bob came up with and if you try it you will also say WOW I like it.
The Sq. router base will do all the work for you with the bearing on the corners of the base plate.
It's a simple design and it's base on geometry ,any two points of contact and the one in the center will always be inline with the two contact points, in can be 1/4" up to 12" wide stock and more.
I should note*** You don't need to make a jig for this type of plunge router setup if you don't want to, the stock can be just put into the wood vise on the work bench and just plunge in and then put the slots in quick and easy with the Oak-Park bearing base plate.
The only thing the jig does is keep the bit sq. and true to the stock.
The bearings that Oak-Park sales have a brass spacer with them that puts the bearing down deeper on the side of stock to help keep it strait and true to the stock.
So to say you can use 1 1/2" or 2" bolts and longer spacers to get the job done without a support jig at all.
I have done it this way and it's a quick way to get it done, but if you put a slot at the end of the ( leg/rail ) you need a end block so the bearing can ride on it at the end of the pass.

But the key is the base plate with the bearings on it.
You may not get the RWS show but maybe send off for some of Episodes you will see Bob and Ricks use this router setup all the time. (router base plate with the bearings )(RWS ,Chair Side Table)
Bearings from Oak-Park to make your own base plate jig.
I should say a word about the Tenon,, Oak-Park sells a great bit just for this type of cut, it's a great bit and will put on the Tenon in one pass on the router table, they also sale a jig (Raised Panel System) to use this great bit but the jig is a easy one to make if you want to, the bit will put on a 1/4" wide teton 1" long but it can be use to put on 3/8" and 1/2" wide teton as well, Bob and Rick did show how to do that when they made a mission type table (Chair Side Table, in Part one of two).
Here's link to the bit so you can have a look see
This bit will also make 1/4" wide splines quick and easy just a plus for this bit.
