While attempting to drill out a new hole in a stud shoe, due to a large knot in the stud interfering with the factory hole placement, I slid off the steel and put a 7/64" hole through the standpipe tail piece, right at the stud. I was working at a poor angle, rushing, and am already extremely upset with myself, and cursed loud enough that my 2 year old daughter now has added words to her limited vocabulary.

Picture is attached. Is there an effective recommended permanent repair option to patching the 7/64" hole? Looking at things like JB Weld waterweld, and not trying to tap in a small screw. Or will the real solution be to cut at each of the redlines indicated on the picture and rebuild it and reattach with banded couplings (ferncos)? - I'm hoping not.

It's a real tight area, and something like a 2" internal coupling would be slick, but I'm concerned about restricted flow, since this is for the washing machine.

Thanks for any advice

I will sometimes use a repair coupling, cut it nearly in half lengthwise, and glue that over the hole.
A repair coupling doesn't have the ridge in the middle. Also called a slip coupling.

Thanks for the idea. I like it, but unfortunately, the hole is right on the edge/behind the stud shoe, and would not get full coverage

Just get a reamer or ram bit:

and do both sides of the 2 inch pipe. Cut the pipe close to the vent. Hopefully your standpipe can be removed easily so you can get at the one side through the stud and then do the side near the standpipe.

This is great, thank you for the advice. Didn't know these existed, and looks to be the option I will be going with. Moving the standpipe out of the way will be no issue, to drill out the tee through the hole in the stud.

That may be easier than you suspect.
