Nice haul. Buy mates for your V Blocks and clamps and you are set. Very cool feature on th B & S center head. As for the horse shoes, you already know how to use them nail one over your shop door! I did 😊
The "sheet metal notching tool" is a a nibbler! You can use it taking lots of little bites to cut out square, round (any polygon really) shaped holes in sheet metal. It is pretty fast once you get the hang of it. Super useful for electrical control panels and similar jobs. You can buy battery and line powered nibblers still today--here's a DeWalt at Lowes for instance: www.lowes.com/pd/DEWALT-16-Gauge-Corded-Metal-Shears/3508974
