How do I temporarily attach two pieces of wood together, face to face, in a way that's strong enough that I can, say, run it through a saw, but that doesn't leave marks on the wood or get in the way of the tool?
For example, let's say I have a piece of wood with jagged edges and I want to temporarily stick it on another piece of wood with a straight edge so I can guide it along a table saw or router fence.
- Clamps get in the way of the table, and are sometimes hard to position accurately.
- Wood glue is permanent.
- Screws and nails leave holes.
- Two sided tape is thick and squishy (has some play, no good esp. on a router), leaves residue.
How can I do this? I have this struggle a lot.
