I'm trying to mount a tv into my chimney walls. My TV is 65" and weighs in about 65"lbs or so. I drilled in 6 holes. 3 at the top 3 at the bottom with about 12" apart. I was going to use the strap toggle anchors since. I used a .5" drill bit thinking I wouldnt hit a stud. As I was drilling, I realized that I actually did hit a stud and probably drilled half an inch into the stud.
Now I have 1/2 inch hole which i would like to repair so I can screw directly into the stud. Do you think I can just take 1/2 inch dowel, sand it down a bit, dip it in wood glue, insert it in the hole, and patch the hole with spackle and then reuse the hole with maybe a 4" screw that way it ill pass the dowel and into some of the stud?
