Sir Brian,
I realize that this thread is very old, but I have a question. I'm glad I found this thread because I was on the same waive length as far as heat bending the wood. After soaking the slats in boiling water, could you clamp it around the sword without glueing it and allow it to cool to the shape? My though is, that if the sword seizes in the slats or is too loose, some very thin spacers could be added when it is glued up and allow more space. Thanks.
