I find nothing more satisfying than using a tool wich you made. I often look for projects to do, and there are plenty of tools on that list. Ive made countless saw blades for use on alumoinum, wood, and brass. Homemade flycutters, and other tool bit holders for the lath and mill.
Here are a couple I use all the time.
This is based on a hand vice I seen in a catalog. I used walnut for the handle. I also made four of them and gave them away as presents. Cant find these at the hardware store.
Here is a 3 inch milling vice I made out of a big chunk of steel. It is verry handy when a small vice is needed.
