oh, geez . .. the Giggity/NutPunch peeps are gonna be breaking down your door for that block. (seems blocks of sufficient size for that design are harder to come by, and that one is so gorgeous)
Box Elder takes to stabilizing like nobody's business. At first, I was a mite concerned about it's natural softness; but there's something either in its underlying structure or just the way it sponges up the stabilizing agent that makes it a great candidate. So, after a few years of making Stab. Box Elder mods and seeing their track record, I'd say it's quite suitable. Although, too, it does depend on what one considers stabilizing to be. There's no small amount of variation in that process either; and I've seen "stabilized" blocks that seem no harder/different than natural wood. Can you make a mark/indentation with your thumbnail? What agent does Greg Dahl use to stabilize?
I don't know what agent he uses, but he uses a pressurized chamber. He does good work. No indentation with my fingernail, it is a quality block.
I can send it, you can look it over, determine if it is suitable, and what size/shape speaks to you. If it won't work, I will pay shipping back to me and it can spend its days sitting pretty on the bookshelf.
