I bought 2 log kits, and prints call for using 2-4’s between logs, I thought this was accepted as the best construction method, I have seen logs cut with a tongue and groove type notching, and laid right on too of each other. My question is: which method is best, what are the pro’s and cons of both, if there is a better method than either, what is it? My logs are red oak and dovetail cut on ends, with steel rods drilled through each end. Thanks-daveo
