When I first started working onthe wood parts of my Model A Huckster, I had a bunch of old tools from my dad's shop. The table saw was an 9" small top unit with an external motor and stepped pulley system. It worked fine for most of the work I had started until I decided I needed a molding head and blade setup to do the tongue/groove for the inset panels. Being new to using these setups, I didn't realize the saw wouldn't have the speed to make the molding head work correctly or safely. The oak I was using had knots and all-in-all wasn't the best for doing this operation either. The first piece I ran through the saw had a knot I didn't see and because of the slow rpm of the molding head the molding head caught the knot instead of just powering through it. It threw the piece of oak backward into the joint of the thumb hold the wood and pretty much tore the joint apart. After a few colorful words and wrapping it in a towel while i cleaned up the saw, floor and other closeby areas, I went into the house and ask my wife if she was busy. When she saw the wrapped up hand she responede as she usually did...."what did you break this time?" A few stitches and a good wrapping..I was back at it the next day but used my router table for the rest of the tongue and groove stuff.
