I'm building a small tool shed for practice. If I enjoy it, my next project will be a house. I tried going over the bark slowly and it would still rip. My spud has a 6 inch blade with a 5 ft long handle, so my knuckles are still in great shape. I wonder if those 3 logs were extra dry and the cambium and wood bonded. You're right about the drawknife, that's probably my best option to salvage those logs.
The bark beetle's have already started eating my investment
I noticed my first one last weekend, so I've started doing more peeling in the evenings to try and finish the peeling this week. Down south, we've had about 2-3 weeks of warm weather (60 F) starting in early April, so that really got the beetles going.
