Intro: Rebuilding Vintage Porter-Cable Router
Old machines like this might not have all the latest bells and whistles but don't think that means they are not as good. Older aluminium body routers tend to turn a little slower, operate smoother and have far less noise. They were built during a time when over engineering was seen as a good thing and stand up well to the rigors of shop use. This old Porter Cable was my grandfather's. Bringing it back was as much about him as it was about the tool.

Things to remember: Bearings do not have to be perfect to be functional. Shielded bearings can be relubricated. Bearings are CHEAP so sometimes it is just better to replace them.
