So I decided to try my hand at one of these basic wall mounts I've seen online using an Ikea cutting board. I have concrete walls. I mounted my tv without issue however this turntable mount is giving me trouble.
I asked the guy in my local hardware and he provided me with the brackets, 3/16 concrete drill bit and some blue concrete screws ( sorry, I don't know the size). I drilled the hole but it doesn't seem to go far enough. When I inserted the screws, they didn't go all the way in. I went back to the hardware and they suggested that I try to widen the holes a tiny bit. I did so with 3 out of 6 screws so far. The first two were fine, the third hole in now two big for the screw. When I hung my TV, I used bolts and I believe anchors on this same concrete wall which is mostly brick underneath. When I went back to the hardware the second time, I asked about bolts and anchors, but the guy just recommended widening the holes.
Is this a stable way to mount the turnable in the first place?? Thanks.
