This isn't exactly a home repair but someone in this group probably knows the carpentry techniques or tools to use. I have a shiitake mushroom garden in the basement; they grow in oak logs and have been producing well for about a half-year now.
What I would like to do is to remove some plugs from these logs and use them to innoculate new logs with mushroom spawn by inserting the plugs into holes drilled into the new logs. The plugs should be about
1/4 to 5/16 inch in diameter and about an inch long. Is there some sort of tool or attachment to an electric drill that will do this?Paul
