Glues and Adhesives

I need to glue two beveled edges together, but have a hard time applying firm pressure on the joint to force the slightly wavy outer edges of the bevels to match.

I lent a friend four clamps to glue up a large project. They came back with dried yellow glue globs on the bars that he couldn’t get off. What’s the best way to remove glue that’s hardened?

I’m making some wooden plaques with glued-on engraved metal plates. What glue should I use?

I’ve built small projects with delicate, difficult-to-clamp parts. Is there some fast-setting adhesive that will allow me to use hand pressure to clamp until the glue “grabs?”

The glue-ups for the curved arms on my Morris chair seemed to go well, but when I took them out of the forms, there was springback. Should I be doing something differently?

I’m a beginning woodworker with a basic question: For making templates out of medium density fiberboard (MDF), what’s the best way to secure paper patterns to MDF?
