Wedges are very useful to have around. If you are using wedged tenon joinery they are a must. You can use them to fill a bad dovetail joint, hold an un-level chair from rocking while you mark out the leg to be cut, repair a bad tenon etc. When I make my wedges I try to make them is a mass scale so I don’t have to worry about running out in the middle of a glue up. I have had that happen, where I had to stop in the middle of a glue up and make a wedge, very annoying. So here are some pictures of the way I do it. I mill up a 6”-7” wide board to the thickness of the wedge I will need.
Then using an angle finder I mark out the taper and thickness of the wedge I will want.
Then follow the lines on the band saw, but be careful to leave the pieces attached. It can be exciting if one comes loose and drops down into the throat of the saw or sander later on. If you don’t feel confident you can leave them attached then you can cut them out using a 10-15tpi blade on your scroll saw.
When you have finished the lateral angled cuts turn the board and crosscut the shims out squishing the piece as you go to keep them from flying away.
If you want to clean them up you can clamp a board up tightly to your belt sander and hit them over to bring them to a good point.
I like to snack on almonds which works out nicely as the cup are great containers for small parts, just write on them with a sharpie what wood type and size they are and they will be ready for the project when needed.
Then stick them in and wallah!
Have fun and be safe.
