I am considering purchasing an LM29. The primary purpose is to use the timber on my 15 acre piece of property to build my home and barn. I mainly plan to use it for the larger pieces of lumber and large timbers for my barn. Afterwards I want to continue my wood working building furniture and the like. I have been a carpenter for years but have no experience using a mill. What are some of your feelings? Will it be worth it financially to cover the cost of the big lumber and timbers? How much practice will i need before i can cut a straight piece of wood?
