So to make a short story long. I got my first plane at the market where fleas are sold. A craftsman with 5c on the side. Everything was there (cracked tote and all) except that brass blade adjustment knob and stud. I mean it's my first plane, how would I know. So I made a new tote however the blade adjustment is giving me the run around. In my research I found the whole left hand thread thing. Go on eBay pick up a brand new adjuster and threaded rod. Unfortunately it doesn't fit the frog. Curses! Off to the hardware store where they have tons of bolts. The only thing I find that even remotely fits... drum roll.... 1/4" 28 tpi right handed thread. Has ANYONE ever hear this? Is there some dungeon somewhere where I can sell my soul for and adjustment knob? Or am I going to have to dust off my metal working skills and make one on the lathe? And I thank you for your support.
