Bought a semi load of logs from Mr. Mahaffney in 2004 or 2005 and had shipped to Florida where I constucted a home . Have nothing but praise for the service nor the product. These were 6x12 logs with chinking groove. I bought a dovetail jig from a man in Tn. and cut my own DoveTails. Everything worked out fine. Am now looking at property in Gilmer County.
