View Full Version : Exploding Ancient Kauri Bowl

Got commissioned to turn an Ancient Kauri bowl which had to be turned to something similar to a bowl provided by client. All was going well, bottom turned and sanded, inside was down to last few cuts and then bang. As far as I can make out, outer section separated but didn't break off completely, then it parted near centre. Bigger half then decided to launch itself at my left forearm, which is now sporting a bump and before anyone says hey there is a few cracks from where its mounted, it wasn't from that.

Blank did exhibit a few checks as I was turning it and I half expected it to happen, but not as explosively as it happened :o as I was keeping a close eye on it :doh:

Red marks are from dust hood and blue is from tool rest or lathe.

No finish has been applied to bottom at all, that is as is from sanding, has been sanded to 1500 grit using rotary sander and paper from uBeaut (http://www.ubeaut.com.au/rotary1.htm).

Bugger, substantial wall thickness as well. Would have been a great bowl. Are you going to try to glue it?

Bummer.

Maybe sitting in a swamp for 40,000 years weakens the timber.

That is a shame, it was looking good as well. At least you didn't get seriously hurt. Might have a bit of a sting in the pocket though I'd reckon.

DJ - you didn't say which way the pieces flew. I assume some went back, what about the rest.

The last explosion here the piece went straight up and hit the ceiling. (Courtesy of Calm).

Had that happen once, half hit me in the belly, and I found the other half lodged in the roof two days later.

No, client has another piece for me.

Yep, blank had $250 on it, at least I didn't have to pay for it.

One piece came straight at my left arm and the other flew off the other side towards dust hood. The 2 smaller pieces on the left in the photos are still joined together but only just.

Pity, sorry that happened.
I have heard of kauri but thought it was always deep black from laying the mud all that time.

Some is dark , some has a greenish hue to it , some has no apparent darkening.
The old people used some types of swamp mud in the dye process for Harakeke(flax) fiber.

its a hard timber to work with. whats your address ill send you few bits. the 12,000 year old swamp kauri dose not twist and warp like the 45,000 year old wood and i prefer the colour.
