I used a 40 year old Craftsman, probably a 1 1/2 or so. It was a full size router. I bought a new HD trim router to do the gains so I wouldn't have to change bits and could leave depth set permanently with both bits. After finishing, I think I might try the trim router for the full job next time. It is not as a stable as a full size, but mdf cuts so easy that it can cut it easily enough. I think if you rout with some kind fence for a guide the trim router is fine. Maybe if you use a compass arm to cut curves, a heavier router is better. Just thinking about how much base you have to mount a guide to.
I will not do this again without have a second pair of hands to hold the shop vac hose behind the router.
I am intending to do a mod to one end of my track after the first of the year. I am going to make a flat curve a larger radius, wider lane spacing and a little banking. A few of the guys that race just can't make it around that corner. Better to re-work it then to have cars coming off every lap and the fun factor low.
Depending on your future use, you can buy a much cheaper router at Harbor Freight. I would check around about them first, though.
