Someone had made mention about the sanding wheel burning cause a problem with gluing - I went back to some post, and I am overlooking who wrote that - my apologies for not responding. I could not tell at all if the burning had any effect on the glue joint. The joint seems to be just like the other ones that I made. The joint held up under the spindle sander (for the one-half frame) so, if it holds up under those conditions, it should be good.
