would like to know what kind of glue to use for attaching glue blocks for clamping a compound mitered tray. should be strong enough to resist clamping pressure, yet removable after the clamping is done. perhaps strong, but brittle?
thanks for any suggestions,
greg

Method 1 - Most of the time, I just use heavy-duty cloth-base carpet tape. The block may creep a bit during clamping, but usually not enough to cause a problem.
Method 2 - If the angle is more than 20° or so, the tape creeps too much, and so I use a hot-melt glue gun. I place the clamp block on the surface, and apply a few dabs of glue around the perimeter of contact. The more severe the angle (and thus the more the shear force), the more dabs I use.
Method 3 - If the angle is so steep that the hot-melt glue is unlikely to hold, I glue the block to the surface with a piece of brown kraft (e.g., grocery bag) paper in between, using ordinary Titebond II glue. It's easy to split the glue line apart with a thin knife, and then its reasonably easy to scrape off the paper bits and residual glue afterwards.
Whatever method you use, there is some risk of minor surface damage, so whenever possible I like to leave the pieces just a bit oversize and then clean everything up with a plane later.

hey steve,
thanks so much, i have all those things already. i sometimes use the carpet tape for stack cutting. i'll give those a shot. also now that i think about it i saw tage frid do something like that with the brown paper on his dvd.
have a great day,
greg

I would start out with double sided sticky tape, pretty amazing stuff. Do a dry(no glue) test first.
Work Safe, Count to 10 when your done for the day !!
