A quickly made fixed MDF thing.

To me a template for the table top would be a circular disc of MDF, do you mean you made a "compass" type attachment for the router as this would have required plunging but you would usually use this with a straight bit as you don't need a bearing.

^. I did indeed make a compass type jig. Screwed a hole in the middle of the piece, ran the jigsaw round first which gave about 1.5mm to remove with the router. This is where I had to sort of 'Jiggle' the router down onto the piece, not ideal but you work with what you have.
I'm making a sliding 'compass' style jig that will allow me to move the router in/out from the center of the circle.
That's what I'm doing on here at the moment, looking for some ideas.

Given the same job I would use my homemade router compass to cut a circular jig out of say 6mm MDf using a standard straight bit. I would then tack this template to the table top and use the bearing guided cutter against that.
On large radius jobs I have used a bodged up router compas with my small laminate trimmer to cut a 6mm x 3mm deep groove. I then bandsaw most of the waste away followed by the bearing guided cutter with the bearing against the edge of the 3mm groove. I used a 5.0m radius compass to get the curved back on this bench, picture B5 shows a similar process but the laminate trimmer was run against a sprundg batten to get the curve under the seat rail as I couldn't get the length of radius inside the workshop.
