I am making some shutters for my daughters house. I'm using 1 x 6 cedar, 3 boards wide by 40" long and Titebond III glue. I had no problem joining 2 boards together, but last night when I attempted to glue the third board to 2 I'd already glued together the clamps kept coming undone.
Here is my procedure for your critique. I've got a piece of butcher paper taped to my workbench to keep it clean. I spread glue on the edges of my boards, struck a couple pieces of 60 grit sandpaper over them to put a little grit in the joint to keep it from slipping, laid the boards on the butcher paper and applied the clamps using light to moderate pressure ( I used 4 bar clamps) then I picked up an end, put some wax paper over the joint and applied a 6" wood clamp on the end to make sure the pieces were even. I cleaned off the glue line using a 50/50 mix of vinegar and water. That's when my problems started. Every time I picked up the other end to put a wood clamp on it the bar clamps just exploded off the workpiece. I tried it twice, once using blocks between the workpiece and the clamps and once without the blocks.
Any thoughts on why this is happening? Should I be alternating the sides on which I apply the clamps? I'm thinking I might have more success if I clamped one of the pieces in my vise and did everything vertically, that would make it easy to clamp from both sides. I'm feeling somewhat frustrated and would appreciate your thoughts.
