I recently picked up an older Rockwell/Delta 8" jointer model no. 37-315/serial LN1281. After pulling the cutterhead I removed the tables to clean and lube the dovetails. I discovered that the adjustment shaft is a bit stripped (see photo). I found one on ebay but the threads are right handed, mine are left handed. Delta's part no is #418044125005. That's the no. I found on diagrams online but mine must be older. Anyone out there have an older 8" they're parting out? I tried searching the classified but can't seem to figure it out. IMG_1107.jpg
