Wow, what a great idea for a thread! I'll definitely be checking eBay for some of these tools. Creative idea to use a wood lathe as a polisher!
I bought a buddy a Handtool rescue adjustable wrench. As I understand, it's a modern CNC replica of an old King Dick wrench. It seems to grab much tighter and opens much wider than it's modern adjustable nut lathe counterparts. I have a properly sized park wrench for adjusting headsets, but this thing grabbed so much nicer on headsets with chrome or black finishes that always seem to get marred. I'll definitely be buying one for myself soon.
