So just how tight a fit do you need to hold a splice? No light showing through at all?
Are thin shims to fill gaps really better than glue, assuming you're using Resorcinol?
If you boil or soak before joining do you wait until dry, then separate them and add glue?
My first attempt failed, but I'm not surprised cause the gaps were pretty bad. The one I'm doing now is better, but not perfect.
here's what it looks like...
the wood is yew and if the splice holds I was gonna remove sapwood and back w/ sinew
