So I finally got around to removing the cambium from an hhb stave using my local car wash and it worked pretty good. After removing the cambium it was interesting to see all the old bug damage that has healed, I have another stave I'm going to wash tomorrow and planning on making a war bow from and want a clean back. Now the only draw back was it cost $19 cdn to remove it all, but I think I can shave a few bucks off tomorrow. I'm definitely going to invest in a pressure washer this summer as I have lots of winter cut staves. Here's a couple pics.
