A lot of time in the shop I take things for granted. As an example my jointer push appliance. If you use a powered jointer you need a good and safe way to push the work over the cutting head. The best I've found is one I've used for several years, well may be more than several. It is easy to cut out and keeps the hand and fingers safe.

Another are doe's foot sticks to help hold wood for planing. A stop, a doe's foot and a holdfast is all that is needed to hold work flat on the bench. It is much faster than using a tail vise. The top appliance is for holding a board vertical for planing the edge, also faster than using a vise to hold the work. Another advantage of the appliance is immediate feedback if your technique sucks.

Just some simple shop made appliances that are in almost daily use in my shop.
