@$##@% Heads!

Broken bolts LOL I did plant maintanance in a textile mill for 10 years. If I had a nickle for every broken bolt I've removed with WD=40 and a dental pick I could buy that resinator I want.
As for the broken tap mentioned, either hit hard enough to shatter it or aneal it ( turn it cherry red with a torch ) then drill it out. Good luck
