Sideline: I renovated my Jap hammer today, ie the shaft. After 10 yrs hard work it had split. I epoxied it back together and built up the top of the shaft (oak) with West epoxy + colloidal silica.
Then I beeswaxed it, after sanding it lightly.
I'm putting my hand back on Shoji's hammer again. I have another, mallet, given to me by a joiner who was on the minesweepers in WW2 in the North Atlantic. Gone now, Dennis...
great joiner.

oh yeah. a really nice broadaxe handle (grandfather's) started to split, and i was wondering what to do with it. that's it.
the advantage to boatbuilding is nothing has to be straight except the keel and a plumb stem. bend a batten to a pretty shape and take it from there.
a bit of math in the morning is good exercise for the mind though.
