Update on PB Penetrant/frozen drill chuck
Awl--
Goodgawd.... The PB peeple sent me a gal of PB *plus* a metal spray can for stream/aerosol type spraying; $25 + ups. Was considering the Kroil, but I'd already spend a bunch of $$ on penetrants. Soaked the chuck for 3 days; no go. Put the slipping pipe wrenches on--no go. Used big-assed channel-locks--no go. Arc welded a bead on the outside of the chuck, put the pipe wrenches on, no go. Put three-foot pipes on sed pipe wrenches, no go. Acetylene'd the goddamm chuck, nice smoke/firestorm, no go. Cooled it down somewhat w/ WD 40, re-soaked it while pretty hot in the PB for a cupla hours Put pipe wrenches back on.... STILL no go! Put three foot extensions on pipe wrenches--FINALLY it gave! goodgawd.... The forces were so large that the bigger pipe wrench actually *wore down* the bead I welded on! Amazingly, the chuck is "freeing up" as we speak! The PB is a bit darker than it was. Should I keep this stuff as "used PB"? Any ideas on the useful lifespan of this type stuff? ---------------------------- Mr. P.V.'d formerly Droll Troll |
