Okay I buggered up when I placed the bow bulkhead in the North Star. I placed it 1.5 inches closer to the stern than I had planned. I wanted to cry but was able to use the boat though a bit snug. I had fileted it in with cab-o-sil thickened epoxy so I knew it was going to be a bear to cut it out. After kicking ideas around for a week I purchased a Rockwell RK5139K Sonicrafter oscillating tool. http://www.amazon.com/gp/product/B008N3RHHA/ref=oh_details_o00_s00_i03?ie=UTF8&psc=1

This tool is great tool for making plunge cuts close to surfaces. Took a half hour to cut out the bulkhead and an hour to grind out the rest of the cab-o-sil filet from the interior surfaces. The bulkhead is still usable for the new desired position.
