I know there are several woodworkers on this forum and I need some help. I have a Porter Cable biscuit joiner that I bought as soon as I heard that Black & Decker was buying Porter Cable(I don't like B&D). After several years, I want to use the 2" blade. I have tried for a week to remove the 4" blade but am having no success removing the mounting screw. I have used Kroil. I have used a cheater pipe on the allen wrench. I have tapped on the allen wrench to try to help the Kroil get into the threads. Nothing works. I am at the point of buying a 5/32 allen impact socket to use with the Bosch impact tool but I am not optimistic that it will work either.
Any suggestions that I haven't tried?
