on a T/C hawken .50 cal?
Respectfully, this is not a good idea! One does not want to compress the barrel metal into the breech plug threads. Wrong way to remove a breech plug!Unless I had a compelling reason to do so I would not try. Those plugs were installed by brute force to time them. They have been in place for decades. The threads will be well rusted.
If I had a really good reason I would proceed as follows. I would find a real TC breech plug spanner. I would shim the spanner tight with brass shim stock. On the barrel side I would use large steel V-blocks, lined with business card and rosin. For the vice I would use my hydraulic vice. The apparatus weight over 100#. I would grab the barrel close to the threads and pump up the ram to about 10K #. To grab the spanner I would use giant cresent wrench. On that would go 5' of cheater bar.
I have had a plug let go by leaning on the cheater bar. I have had one that required over 500 foot pounds and wacking the wrench with a small sledge hammer.
The chances of getting the plug out, and not damaging the plug and or barrel, using home shop methods is slim.
I submit if you tried the same thing today it would have 20 more years of rust and fouling built up. Maybe thats why the 98's were so hard to pull...they were WWII vintage and had 60 plus years of rust.I didn't know T/C breech plugs were so hard to remove so i just went ahead and did it with what I had. Starting with what some are calling a spanner to fit the breech plug, I clamped the barrel in the wooden jaws of my Workmate, and using a large crescent wrench and a cheater pipe began to work. The Workmate jaws held, but the entire little bench tipped. So, i had my 125-pound wife set on it. That was all it needed. Of course that was 50 years ago and now I know better. Today I'd use a 20 ton press to clamp the barrel and go to all the other trouble advised above, because i now know the right way to do things. I pulled the plug to properly lap the barrel.
I wrote CLOSE TO the threads, not over the threads. What I wrote is how to reliably remove the plug without even damaging the blue. This is based on hears of experience and an understanding of how the barrels were breeched a the factory.[
