Cutting a 3/4 Sill Log

In a log structure the first course of logs are called sill logs. The first set of sill logs are called half logs. These logs are half of the average tip and butt diameter of all your logs. The next set are called whole logs or 3/4 logs. To put it simply a whole sill log is about 3/4 the thickness of your average tip and butt of your logs. There are a lot of things that you have to consider when laying whole logs out to be cut but, I won't go into it here. I'll refer you to the Log Construction Manual
