Using the pantorouter for furniture repair

I am the Facilities and IT manager for a Public Library. Kind of a weird job combination, but that's what happens when you work in trades to get through college ;)
The pantorouter that I built for work was done in fits and starts over a 7 month period. I built mine at home in about a week! The one at work uses the followers from Kuldeep...I think we have the 10mm, 15mm and the 22mm. We also made templates similar to the commercial ones, which really makes setup easier. I had some trouble getting the oddball Milwaukee router mounted in it, but we had it on the shelf.
Repairing chairsWe normally get about four chairs each week in for repair. The problem with these chairs is that they are put together with dowels. This design may have worked OK in a situation where they would receive light use, but when subjected to the public on a daily basis they just don't hold up.
We have come up with a way to repair them that has held up quite well.
The failures are always at the point where the leg joins the apron with
two 3/8" dowels. Once this joint gets loose the days of the chair
staying together are limited.
What makes this so easy is that the references everything from the same face. As long as you have the template in the machine centered and square, there isn't a whole lot of places where you can screw it up.
Repairing TablesWe have about a dozen tables that are developing problems. Like the chairs, they are not designed very well. They have no apron support for the MDF top and all of them are bowing considerably in the middle.
Our solution to repairing these tables is to add a proper support system under them. We will be using 3/4 x 2 1/2" hard maple for the aprons. This is as tall as we could go and still provide clearance for the arms on the chairs to go underneath them.
Now we will make the mortises on the existing legs Here is the assembled base. We also screwed in and additional support to the inside of the leg...I thought about mortising these into the leg as well, but I didn't want to complicate the glue up. Our shop is close to the boiler and is usually pretty warm; glue sets up fast.
