What should work is to get a new plug so you have the best threads possible. Coat the new plug with 3-4 coats of wax or other release agent J-B weld, plasti steel, bisonite, or other epoxy with a steel base. mix according to instructions. Put a light coat in the threads in the hole. then a coat on the threaded plug screw together and let cure. The goal is to get a full coat on the threads with out to much being pushed inside. If theres room a small boss around the hole could be made with clay giving more threads to hold. Keep in mind doing it this way will result in a zero clearance thread fit, They will be tight all the way. Especially with J-B weld or bisonite as they both slightly expand when hardening.
I recently fixed a water pump housing with J-B weld where an ear had broken off. cleaned the joint good and glued it giving a light coat inside over the joint. By cleaned good I wire brushed it then precision green solvent a couple times then mild heat to burn out any moisture or oils.Used a couple hose clamps to hold the lip in alignment and location. Let cure over night. next day removed clamp cleanded up over runs and assembled could tighten up the broken ear as tight as the other 3 but it holds and no leaks at 60 psi.
J-B weld is good and holds where you dont want the heat od brazing or soldering.
Being cast iron you could braze up the hole re drill and tap, but you would have to disassemble the whole base really clean and then preferably pre heat the base to keep from cracking.
27 threads per inch is a pipe thread pitch also a British and bicycle standard.
Hokey smokes...Send it to me...I will pay shipping back to you...Fixed... No Biggie...
Well, gang, this is exactly what happened.
After a phone conversation, Rockindaddy had me ship my Star sizer to him, and he did his magic.
Not sure of the technical terms of what he did but basically he drilled out the hole, threaded it, the MADE a plug to fit.
Funny thing about our gun community - when we were talking on the phone, and he said send it to me, when he gave me his name, I recognized it immediately.
Those of us in the NFA community recognize his name instantly. He made MP40's on registered tubes. Lots of them! Many years ago, those registered tubes crossed my path at a dealer's. What a small world it is, indeed!
I can't say thank you enough to him.
I did a bullet casting seminar at my local range clubhouse and it worked perfectly.
This is what makes us all connected - the love of casting reloading and shooting.
Thanks ROCKINDADDY!
