Safe way to use double sided tape
When using double sided tape it can be difficult at times to get off the workpiece without damaging it. A simple and safer way to use double sided tape is to use it in conjunction with painters tape.
First put a layer of painters tape down on each piece of material. Next place the double sided tape on the painters tape (only on one of the pieces of material). Then press the two pieces together. This sandwiches the double sided tape in between the painters tape. When it comes time to take the pieces apart it will separate much easier. The painters tape will release with less force. Since the double sided tape was sandwiched between the painters tape you wont have to scrape the stickier double sided tape off and possibly having to get rid of any residue.
