Yay, Santa came through on the new router for Christmas, albeit a little late (he wasn’t sure what size I needed and was in my area on Santa business). It’s a Bosch 1HP palm router featuring a speed selection and detachable handle for a nice circular area to hold on to. Naturally, it was smaller than CNC router holder and the adapter for the other router.
I tried and failed at a complicated three-jawed system within the old adapter before getting new material. By chance, I found the same diameter PVC pipe, but with a thicker wall and made it work by cutting out an inch section and the pipe was able to close over the router body. A notch had to be cut on the bottom side to allow access to the shaft holding button (or whatever its called).
The tool holder is squeezed pretty tight, so a new one may be the first project. Before that the table still needs to be milled flat, which I guess is the next step.
