I'm still thinking of making a router version, only I was going to use a set 0f 1in. dia. linear rods and bearings I have on a pivot type setup, so I can make interchangable bars for it, and hopefully control the depth with a micrometer or something, altough I may do a z-axis for depth, so I can convert the machine into a cnc version later down the line should I decide to. I will still have make the carraige, and fit the bearings I have for it, but also still looking for a cheap gear motor and variable pot, along with ballscrew to drive it, and a few other parts, so hesitent to start fabricating any mounts or the carraige until I'm sure on the final design I want to use, and have all My parts for it. I found a source for pullies and all, but has been hard to find lowcost gear motors with the controllers and ballscrews. On the otherside I'm caught between using some of the parts I have for that on a saw machine instead. I'm just really still undecided I guess.
