Why not vertical?

I keep meaning to get some double sided tape to give it a try. I've seen it used by lots of people, so I know it works as you say. spray contact adhesive is another one I heven't tried yet.

Works but it's messy.!! . . . . Cheap carpet tape from Wicks works best for me. OR the real good 3M stuff if very expensive material or small area part.

I'll be using it with wood, so don't want it too sticky that it raises the grain. need to experiment a bit.
