Fasten a temporary fence
When you're woodworking, you often need a temporary fence or stop on a table saw or router table or other power tools. Clamps aren't always an option because they can get in the way, and you probably don't want to drill holes in the machine's fence or table for bolts or screws. Instead, use a few dollops of hot glue to hold your temporary fence in place.
Hot-glue parts together for shaping and sanding
When you have several identical parts to make, hot-glue them together and work on them all at once. This will save you lots of time, and all the pieces will be exactly the same. Don't use too much glue—just a little dab will do ya. Use too much and it can be nearly impossible to separate the parts later. Apply glue near edges so you can easily cut it with a putty knife later.
