Who do you plan on thunking with that mallet Gabby?
Not who, What!
I'm into making Didgeridoos now and the hollowing process requires a lot of banging on a modified gouge now a curved chisel, I'll have to upload some photos when I get them.
I'm in the finishing stages on a really cool one, just glued it back together last night,
and am in the process of final sanding and shaping where needed. I blew a test toot on it and I think it's going to sound just great.
A quick "for me" explanation of the process, first select a suitable log, (I've been using standing dead cedar trees of a manageable size (6 to 8' long and about 4 to 8" on the large end), seems to work best. Remove bark then split lengthwise. Use whatever tools available (I'm using a sawzall for splitting & plunge router with a rotary rasp for the rough work, then the chisel) to remove wood leaving a shell about 1/2" thick, once you have all the unwanted wood removed, smooth it up on the inside, make sure both halves will mate well, apply glue to one half and join using large hose/ pipe clamps that you can tighten with a cordless drill with nut driver attached, let cure and commence finishing to your satisfaction. Then blow to your hearts content. LOL
That's the quick and dirty explanation.
