I don't have a vise (or a table to mount it to).

and i paid 5eu for the lbs to remove a hyperglide cassette. i was expecting it to be free... i couldn't tell him to put it back on, that would have been hilarious.

I bought a can of some stuff that claims it loosens tight threads or something... i think its the same stuff, hope it works. Sprayed some a few min ago, ill do the same tomorrow morn. and then tomorrow evening before trying to get it open again.

And i am anchoring the wrench to a blast door, very little slip, i watch to make sure there is so slippage. (i do all my work in a above ground bunker, which is a bike place now lol.)
