Topic tags/keywords: small box miter joint cocobola hide glue

I am making a small jewelry box out of cocobola. Here is the rub: The sides are angled 30 degrees. That of course is making glue up difficult. I have not started to glue yet, but my dry runs show me it is going to be difficult to get the proper “pressure” in the right places, for the right amount of time. Here is my plan so maybe some of you can critique it. My piece isn’t REALLY oily, however, I still plan to wipe several times with acetone immediately prior to glue up. I plan to place on a flat board (MDF) and use a band clamp with metal triangle pieces to hold the bottom. I intend to use four 90 degree framing jigs to hold the top (the inside edge has been routed to 30 degrees). Prior to glue up I intend to use the table saw and a jig I built to cut splines (one top, one bottom), the jig holds the joint together for a precise spline cut. Finally, I am intending to use hide glue with some of the cocobola sawdust I have created in case of squeeze out and/or a little open miter. (All the miters look good in the dry runs) Suggestions?

Forgot one thing….it has been suggested that I use tape, masking or blue painters tape to help hold the joint together during glue up and also to keep the 90 degree framing jigs from sliding up….

Check these clamps out. Corner blocks can be added to the band. I think something like this, or even just a simple webbing strap clamp would work just fine.

I would concure with Blaine, I’ve also used elastic bands in addition to the tape, works a charm. You may also consider tapping off the areas where potential squeeze out will occure, this makes a nice clean up once the glue sets.
