Some blanks I make require gluing full length stripes. They also need to be perfectly square. I've always used small clamps with the segments sandwiched between plastic strips. It works but it's very easy to end up with mismatched pieces and out of square. I came up with this jig today. It's spring loaded with no sideways force. I can also see from the ends if it is still square. It's two sided, glue up's are completely surrounded with hdpe plastic so glue won't stick to it. I'll put some spacers in the ends, slightly larger than my segments, glue them up, drop them in and remove the little spacers. Top is all accessible so I can make sure everything is pushed down.
