I need to find a good method to bore out logs that are about 6 to 8 inches in diameter. The bore would be about 5 to 7 inches in diameter. The logs would be about 6 to 14 inches long. I need to bore a clean hole. I then carve any of a large variety of patterns, artwork, etc. on the exterior.

2012年10月11日 · Once you have the holes bored, you could use a long slender bladed saw to connect the holes (like a long keyhole saw or any thin saw with a blade that can be removed and reconnected inside the log-like a tree branch saw).

In California, they used to straight bore through large squared off sections of redwood logs and use them for municipal and private water pipe. They’d last for decades and we regularly dug them up in NorCal when I was in underground construction.

Boring logs provide the basic information for the selection of test specimens. They provide background data on the natural condition of the formation, on the ground water elevation, appearance of the samples, and the

2022年4月8日 · Once the hole was clear through the center of the log, he used a drawknife to taper one end of the pipe. The tapered end of the pipe fits into the bored-out end of another pipe. Just before locking the pipes together, he wrapeped a rag around the joint to minimize leakage.
