odd joints and glue...

 I've cut the parts and routed the hidden spline slots for assembly of my small wood chapels that will hold a "choir" consisting of samples of American hardwoods. Two chapels will be free standing and one is designed for wall mounting. After the parts are sanded, they will be glued together, a back will be fitted, and the galleries will be installed to hold the members of the "choir."

An article in Fine Woodworking this month illustrates making the "perfect mitered box." We all know that perfection is in the eye of the beholder, or more accurately, in the relationship between the observer and the object, and takes into consideration a wide range of values and experiences. I asked the author about his assembly of the perfect mitered box without using anything but glue. He had used a technique of pre-gluing the mitered ends and refrained from using any further method of strengthening the joint.

I was not the only one to question the glue only technique, and he was having to answer a number of questions from readers on his assertion that glue could be enough.

My thought was that if he could provide evidence of the effectiveness of a glued-only mitered joint, I could use it in this project that I hope will last a century or more when complete. Still, I could not resist doing what I know would work best. To spend a few hours making fixtures to hold the parts for routing, and then to spend a bit of extra time during the gluing operation makes perfect sense in light of the assurance it will not fall apart due to the expansion and contraction of wood.

Today in woodshop, my first and second grade students will be finishing their tool boxes. My upper elementary school students will be working on a variety of projects of their own interest.

Make, fix and create...

  1. Did the FWW author insist that the glue used be from apes?
