When it arrived here I put it and the other blocks in the curing oven which can stay on indefinately so with it at 55*c for 4 days I was sure it had no moisture before putting it in the vacuum chamber with the cactus juics and under vacuum for another 4 days although the bubbles has stopped rising after 3 days. Releasing the vacuum I left it sit for a further 6 days for the atmospheric pressure to drive the juice comp;letely through the blocks then drain it and baked it at 90C for two hours to cure it after which it was sanded to check for any flaws and the best block chosen (best in terms of grain and colour as they all came through the process equally well) so it could be cut into scales with the off cut tested for integrity by bending it, and a very thin piece of end grain wood usually breaks at the slightest bend, but this held up to some serious testing before a deliberate stress finally had it give way so I am confident in the handle integrity. Had I been less certain I would have laminated a very thin slice of long grain from one of the other block with that grain oientation but believe it was not necessary in this case.I can only hope you are wrong. But i have not seen it used that widely in production of anything.
I believe the Cactus juice treatment is widely used.
I beliveve Garry was a carpenter before he retired to become a master craftsmen. Mmm, do Kiwis own any Redgum trees?
The timber block should be well seaoned. I expect that tree was long dead when i removed the block. It then sat in my shed in dry old Western NSW before going to the South Island with a somewhat different climate.
Garry has done his best. If it outlasts him he will be off the hook for warranty work and i will have to find a better timber to revive it.
Its in the post i will update
