Quick question, Does anyone know off the top of their head what size pipe plug to use for the fill port on a 741 case? I accidentally got por 15 on the threads when I painted it and had to drill the stupid thing out. (DOH!!)
 
Yikes! Next time hit that epoxy with a torch or soak with any thickened paint stripper containing a chlorinated solvent : methylene chloride, toluene etc. Use the stinky stuff not citrus based. Most epoxies can only handle about 155 degrees F before falling apart. Ive been a coatings contractor for many decades. Cured resins on metal tools are torched off regularly.
 
Thanks for the info guys. I didn't realize I did that. Didn't have much of choice once I twisted the square off of it. Live and learn.
