Well, I'm actually going to do it. I have a Viper barrel vise, NSS barrel nut wrench and NSS Action Wrench. I tried to find rosin locally but couldn't find any. Going to try the toilet paper roll trick.

Any suggestions on tightening down the screws on the barrel vise?

Should I use heat to break the sealant? I have a propane torch and a hair dryer.

I'll keep you posted.
