    Hi All,
    I have been thinking about trying to make small, two-part hollow forms and boxes. As I have been reading about these, several authors have mentioned “collar joints” to ensure good alignment when gluing up two different types of wood on hollow forms. I am not familiar with this joint. Can any of you enlighten me?
    Thanks,
    Jon

    I have used Corian material as a mating joint and collar for boxes in the past. The main concern is having a stable material for the mating joint that does not expand or contract at different rates when exposed to humidity changes.

    Interesting. Is there something showing this on the forum or a Youtube video?

    Corian comes in a variety of colors and CA glue will readily bond it to wood, it also turns and sands and polishes like hard woods. If you select a proper color it can accent the wood piece, they make solid colors and a variety of high end materials that look like stone. You can also thread this material if you are looking to make a threaded joint.

    Help! Couldn't find anything on collar joints. Just a bunch of regular types of joints and joinery.
