Show us your home made tools

Here are a few. The first is a Allen head bolt welded on another. The allen head is the perfect size for most trident gear clamps. Makes it very simple to tighten or change clamp.
A water filter for my grit blaster,works great.
Two 6 inch wrenches,cut and welded together. Stick it in your back pocket on Saturday morning when you are out doing little chores in the yard, comes in handy.
When I take the sand out of the blaster I screen it to take the crap out and reuse the sand,simple but it works.
