Reading some of the posts got me to thinking about my workroom.
I use a carpenter's T-sq, a regular sg, 4' long rulers, quick clamps, hand clamps. Heavy equipment nuts/washers make good weights.
A rounded off wooden dowel makes a good point turner. I sharpen the dowel in a pencil sharpener, then use sandpaper to soften the point. I like mine about 18", but you can make several sizes if you like.
You can find wood, hard rubber, hard nylon mallets, take your choice.
An empty builders snap-line tool with your choice of marking powder also works great. So go exploring in the tool dep't.
