Norm so you are guilty too of tool mods. laugh I got some pretty weird looking ones but they are time savers.

I got several cheap Chinese made tools that I modify when I need a service wrench to get in an extra tight place. I also design some my own tools at time. Just an electric PTO double D holding tool so torque the retainer screw. Currently done in aluminum but may need redo in steel. Currently set up for 1-3/8 and 1-1/2 double D's.

Here is another tool I had made as the machinist next door has access to the needed tools to do it. It is a chain brake reset tool for Husqvarna saws. Funny I was getting a lot these chain brakes where the customer would remove them without reset the brake but since I had the tool made I have only seen a couple. Sounds just like my luck.
