I have a 3 1/4 HP Makita Model 3612 router mounted in my router table. I notice that when I turn it on and look at the spinning bit, there is the slightest wobble. Even though it is barely perceptible, I am getting very small scallops on the piece, so small that you cannot hardly see them unless you apply finish, then you can surely see them . On soft wood like cherry, it is not too much of a problem to sand the marks out, but on hard wood like white oak and pecan, it is a real chore. When I turn the router off and try and move the bit and collet shaft by hand, there is the very slightest slop.
I have run some big tongue and groove bits, door making bits, and raised panel bits in it, but I have always used a speed control to lower the RPM's on the biggest bits. So, it has had more than light use. Has anyone had this problem and is it repairable? It was about a $275 router.
