Some of you may remember a few weeks ago when I was trying to figure out how to rebuild my B's generator. Through the help of the forum and the wonders of the internet, I have a pretty good understanding now. Below are some pictures of my "new to me" armature undercutting tool in action. I found the tool for sale by someone who had no idea what it did. I bought it and eventually found the inventor's original patent diagrams and claims online at the US patent office. They fully explained how to use it. The patent on this tool was September 1944. I wonder if the inventor thought it would be in use 60 years later! I'm sure this may be common knowledge to many of you, but I thought it was pretty coll and I just had to share. I may post more of the rebuild as I make progress. Here are the pics:

Great find! Dont forget to undercut between the laminations. I use a hacksaw blade ground on both sides to about .020" thick to remove the "set" of the teeth. This makes it thin enough to clean the edges of the copper laminations without changing their width. It also allows the teeth, when pulled with the "hook" toward you to dig slightly into the formica between the segments thus "undercutting" the commutator. This allows the brushes to have full contact with the copper and not be held up by the non-conductive material between the segments.
