Mortising Jig Complete - No router to fit it

So I got the plans for this nifty mortising jig, gathered all the hardware, cut out the parts, turned the knobs, and assembled it this past weekend. I completed the last two parts this evening, only to realize that none of my routers fit the base plate…. Boy do I feel silly.

I suppose I should draw up a new larger plan in Sketchup. I did find a couple mistakes in the original plans… and I did think that the throat could be enlarged to accomodate a bit larger mortise.

Or I could just go buy a new router instead.

I’ve been needing something like that. Where did you get the plans? Looks like it would not be too difficult to rout out a recess for a plate. Hmmm. Ideas flowing. Thanks for the kick to my lazy old brain. Favored it for more study.

I would go with the new Router, they are like clamps, never have enough of them.

Of course you guys would egg me on.

I have four routers (all old) a Black and Decker plunge router that won’t run and can’t find parts for, a Makita Plunge router that runs great, and two Porter Cables with twist bodies – one runs and one does not. I’ve replaced bearings on both the routers that run, but there have been many times when I wished I had a new router with all the parts that came with it, instead of hand-me-downs I bought cheap from a friend…

So, yeah, I should probably buy a new one.

Any recommendations? The base needs to be smaller than the 6” wide base plate.

Nice Jig ! As far as a router with a base smaller than a 6” that may be tough unless you aren’t looking for a huge router. The Bosch Colt is a great little router and has a 4” base but you’re limited to 1/4” bits and it’s only 1 hp.

The Bosch 1617 has a fixed base that is 6” in diameter. All it has to do is fit the 6” x 7” base plate.

Of course I could just make the top 1” wider and the base plate 1/2” wider, and it would fit my Makita plunge router. But that would mean crossing my fingers and hoping the glue wasn’t holding very well after I took the screws out.

Here’s a video of how to use this thing.
