I would appreciate any advice on resawing seasoned 6"-10" wide boards of the following species for a customer, on my WoodMizer sawmill: cocobolo, bubinga, and swartzia. He's got 8/4 boards and is hoping to get either three half inch boards or four 3/8" boards out of these. That doesn't leave a lot left over. I realize I'll have to rig a baseboard underneath as the mill won't cut 3/8" off of the bed rails. But are any of these which will be so hard that they won't be a match for a new DoubleHard blade?

From contributor S:
I don't have any experience with these particular woods, but I have resawn a good bit of material, using both my bandmill and my horizontal resaw. From my experience and what I have heard from others, resawing expensive, dense, dried tropical hardwoods should only be done on a horizontal resaw equipped with an air hold down system that will keep the boards flat. I've also heard of using carbide tipped bandaw blades for this. The blades cost $200-$300. If your customer only has a few boards, he may be alright with you trying to resaw on the sawmill, but if you waste a bunch of his wood he's not going to be a happy camper. I would suggest that you pass this job off to someone with the right equipment or if this guy has a lot to do, and consider getting a horizontal resaw of your own.
