My mom (88) biought a new home and her old one of 40 years is in great shape considering...Trying to fix it up for her to sell to pay for the new Patio home. Except her "Handyman" for want of a better name, mounted a wall bracket with Toggle bolts through fine Hickory Paneling. Two jagged 1/2" holes in the middle of a wall. Can't replace the Paneling but I do have a few pieces I took from a Bar that I dismantled. I was considering a 5/8" Bung I can cut with a Plug cutter set, using the scrap Paneling. But my delima is how to drill a smooth hole 5/8" in a gaping 1/2"+ hole. Any suggestions. I have a 5/8" twist drill bit as well as new 5/8" spade bit. But with the hole missing and on the wall and all, I am feared of making a larger mess.
