Mechanic tricks

I'm not sure if I'll post very many of these kinds of things up here, or at least not very often, for tow reasons. 1- It might scare people, what it takes to get the job done sometimes and 2-I haven't decided yet if it constitues trade secrets (maybe just me wanting to keep business).  Anyway.
A 1990's Italian steel Bertoni with Shimano 600 came in for a drivetrain upgrade.  Everything goes smoothly until the drive side BB (Italian thread), throughly seized.  A couple of differnet tools, penetrant and some time with the race in a vise with the frame as the wrench and still no movement.  So I figured I'd try a method similar to getting off a crap freewheel (using the QR or axle as a tool brace).

 

So that is a semi-disassembled (cups removed) headset press holding the appropriate 36mm wrench tight against the tool flats of the BB race.  A few taps with a hammer on the wrench and a reposition - bingo.  It's always nice when you don't have to resort to blow torches or welding nuts on to stuff, or even worse, busting out the grinder and destroying parts.
