QRBP Repair Busta' way

Umm... yesterday i dropped the breech plug. It hit perfectly on the big round ; i thought all was good... but then it bounced, rotated, and hit on the thin rim, bounced, and hit on the rim again. What i was doing, was trying to avoid using a solvent to clean the plug, since i have been coughing because of some malady. A small piece of scotch brite pad was chucked in a drill motor, and holding the plug in one hand, and the motor in the other, i commenced. It didn't take long, and the plug took a trip from my fingers to the floor.













Not long ago Busta noticed a QRBP i had modified, was leaking around the end, and suggested i use a bolt to open up the rim, and refit it to the rifle. It was done, and it was an improvement. The bolt i used had a tiny bit of thread on the nose, so i put it to the grinder a tad.










Then the bolt and the plug were squoze some in the vice.











Then the plug had to be remarried to the rifle, but the fitment mortice was filled, so a pipe wrench was used.










Then for some assistance against leakage, i wrapped the end of the plug with one wrap of teflon tape.











The single wrap of tape didn't impede my abilitly to install, and remove the plug using just fingers. After 9 shots, here is what the plug looks like...

Nice save. :yeah:

good save is right! nicely done

Nice 8) Better hold onto that bolt and put a rug under the rifle next time... :mrgreen:

LOL a wad of steel wool chucked in a drill.. What could go wrong? Nice fix though. Im starting to wish more and more that my wood shop was a metal shop

Hey Ron,
Good save. To make things a little easier, you can put the Teflon tape over the threads in the back instead of the front. That would make it easier to insert/remove for 75% of your threading/de-threading. A gas tight seal is a gas tight seal and it doesn't matter where it happens.

After you squeezed the breech plug/bolt ends together, did you have to turn the bolt to help round out the breech plug end?

Nice work as usual :yeah:

No, i didn't think to do that, but it seems to me i should have. Seems it would lead to a more better end result, if the bolt was rotated. Somehow what i did worked; another example of dumb luck?

Only problem is, if you only tape the rear threads, the front threads will still get contaminated with residue if the plugs seal leaked. Not a big deal with BH powder however.

Putting the tape right on the end did not make it difficult to install/remove the plug, so changing the way it was done today, isn't something i plan to do; it was easy. Keep in mind i was trying to make the plug work, the way these plugs are supposed to work, when they are new. I agree a seal is a seal no matter where it is, but i didn't/don't want soot on the threads up to where i have the plug wrapped with the tape. Many times in my life, i have seen where the easiest way is not the best way; other times it turns out, the easiest way is the best way.

It looks as if it came out well.
