I have had problems in the past with getting a strong corner on a 45 degree cut, such as you would use in a picture frame or mirror surround. I just can't seem to get the corners to glue up correctly.
Here's what I've tried in the past: (1) Simply gluing the corners and using a strap clamp to hold until dry. (2) Using glue and those squiggly corner inserts you tap in to hold. (3) a combination of 1 & 2 above. (4) Glue and finish/brad nailing the corners together.
Here's the usual outcome of the above: (1) Corners slide all over the place when trying to attach the strap clamp, typically ending up with me throwing the whole works in the trash and grabbing another beer. (2) "Squiggly" corner tap-ins split the corners out, typically ending up with me throwing the whole works in the trash and grabbing another beer. (3) See 1 & 2. (4) Corners split out and/or nails/brads don't set correctly.
I have many feet of great mouldings I've saved over the years with the thought of making some nice frames, but I'm getting frustrated! Can anyone PLEASE offer some advice on how to get better results? I have no problems with cutting and getting nice tight, square corners, I just can't get them assembled! Also, because most of my efforts are "one-offs", building a bench-top template to hold them while drying doesn't seem like the best approach.
Thanks in advance for anything you can offer.
