I have a log house built in the 1930’s (Full logs with about 4 inches of concrete chinking between the logs) I am adding an addition to the log home. (2×6 stick built) I have pine trees to cut down (8 – 12 inches in diameter) I plan on cutting them in half and trying to match the half log siding to the original full log construction. I think these logs will be heavy for screws even if they dry for a while. I dont want the screws to show. Hoping to cover the heads up with the cement chinking
