I'm a a handcrafted log builder in Scottville, Michigan. If you're looking for someone to do plans contact Ron Kemp. His website is www.mcadd.8m.com. He does great work at a very reasonable price. He's got lots of plans on his site to look at. If I can be of any assistance let me know. George - Natural Log Homes 231-690-0036.
I can be reached at email@example.com. If you have questions about the jig or anything else, let me know. Its a slow winter and I've got lots of time.
Oh, the company linked below sells the exact jig I'm talking about, except that they had my friend design it, then they just started selling it without paying him a cent. But it gives you an idea of what I am talking about, and if my friend can't make one for you, you'll be able to get one through these guys.
Click on the link on that page called "Dovetail Construction Techniques" for a couple of useful pictures. Sadly the jig pictures are a bit nondescript. But the make different sizes for different sized logs. That's why you sort of have to make your mind up ahead of time.
The chinking is a bit fake. You don't chink before putting in the window bucks (frames) and other finish details. Nor do you chink before staining the logs. But at least the first picture will give you an idea of what you're getting yourself in to.
I'm guessing, because I'm a sensitive kind of guy, and because I can see your Ranger Airborne icon, that you were an Army Ranger. My nephew Shane was a Ranger out of Ft. Lewis until 2005 or so. He hurt his back in a helicopter rappelling accident and eventually had to get out because he couldn't carry the heavy loads anymore. But he loved it while he could do it. He did duty in Iraq and Afghanistan during the two invasions, and a bit more later on.
Me, I was an Air Force puke back in the 60's. At least that's what the Army called us back then :-)
