Restoring a Stanley No. 71 Router Plane

There are two schools of thought about restoring old woodworking tools. Some say you shouldn’t take a tool back down to bare metal, but instead give it a thorough cleaning and preserve the history and patina from decades of use. Others suggest that it’s okay to make an old tool look brand new again by taking it down to bare metal, repainting, etc. Both have their place among woodworkers and tool collectors and neither is wrong, they’re just different perspectives.

My theory is less is more, but there is no single way to do this. I tend to lean more toward giving old tools a thorough cleaning rather than wire brushing or sand blasting a tool down to bare metal and making it look brand new. Having said that, I have done both, and on this web site I present information about both of these methods for tool restoration as there is a place for both.
