Henri Grissino-Mayer's Ultimate Tree Ring Pages (on the web) have a load of info about the care and feeding of increment borers. Here is the info from his page(s) on this topic: ** *Removing stuck cores*: If you jam your borer to the point it can't be unjammed in the field, take the auger back to a wood shop. Using a series of narrow to wider drill bits, use a table-mounted drill press to precision drill the jammed wood through the tip of the auger. Then clean out any residual wood with your gun cleaning kit.( http://web.utk.edu/~grissino/alltips.htm)
I highly recommend attending one of the dendro field weeks in the summer. They rotate around the country. The cost is reasonable, the instructors are great, and you do a complete project from start to finish during the course. You also learn all about increment borers, increment cores, belt sanders, and all kinds of great tools. On Wed, Nov 19, 2008 at 7:23 PM, Gary A.
