My newly built machine is currently running with a Porter cable 690 series, (694) the variable speed one. I thought it was a good choice because it has a high high speed (27,500) and i plan to do some inlay work with tiny bits. Problems are: 1) it's very loud, especially at higher speeds . 2) because the bits can't be inserted beyond the bottom of the collet, long bits are forced to have a long projection, increasing stress on the bearings, and creating other problems hard to describe. I use the machine mostly for cutting joints, with router held horizontally, but also conventionally for pocketing boxes and trays, and I hope, inlay. I"m wondering about people's experience with the following routers for CNC work especially, considering collet quality and runout, and noise level: Makita RF1101 (anyone know its motor diameter?), Bosch 1617EVS , Freud FT1700vcek, porter cable 892. I own a brand new Freud, and it seems perfect -except its a weird motor diameter, 3.692" so I"d have to irreversibly alter the K2CNC 3.5 inch motor mount to accept it. Anyone have experience about how important bit speed is for cutting inlays with tiny bits, like .02? DO I need a second trim router )Bosch Colt) for this? Thanks!
