Sorry to sound dim, but I've been trying to find a 'how to' guide on setting up a router. 1.Does anyone know of one? 2.If I wanted to route slots say 9mm, 12mm and 18mm wide, would I need to buy 3 'router bits'? 3. I need a router for a one-off fence paneling job. So the choice is to hire one or buy a cheaper model. It would be nice to have one in the kit, bearing in mind, with fencing, I'm not looking for a pro finish - what are folks' views on the cheapo multi-speed routers in the £30 - £45 bracket? Thanks.
