When using a router as a spindle, there are several things to consider. First, the routers are air cooled. This means if you run the router at lower speeds, you have to watch for overheating. Secondly, the airflow is directed from the top of the router down towards the work. This means it will nicely blow the chips away from your cutting tool, but will also dramatically increase the volume of dust colletion you need to control the dust that will otherwise coat everything in your shop. On my gantry I went with a long shaft die grinder ($24.00 from harbor freight). The spindle is not the most accurate but plenty good for my needs. THe long shaft provides a nice mounting area and keeps the motor away from the work. In addition, the cooling air for the motors is not directed at the cutting area making it easy to control dust from the operation.
For better quality long shaft die grinders, you might check out the bosch or similar units. They come with collets down to 1/8" (cannot recall the metric equivalent). HTHs.
