Very nice mon ami. And i am right behind you with this project. Not the same but your idea did not die on the vine. Its just circling the airport with my other 12 projects waiting for time and a landing strip to become available. Heck i even got my wood and wheels for my lot. Ok some of my wheels are in another country in custody but they gonna land when they are needed.
As to the extra tool holders THAT my friend is a clever idea. If its yours originally send it in to Shop Notes.
The grinder brings up the point about does one have two grinders if one has a lathe? This is what i am beginning to believe.
