Needed 1/2”, bought 5/8 by mistake, HD is closed and need to get some mud on to dry overnight. I figured I could set my old Stanley 78 to 1/8” depth, flipped the spur cutter out and cut a rabbet in about a minute, lol.

In all seriousness though that is quite an ingenious solution.

Knowing what drywall does to razor blades, that makes me cringe… LOL

If it works.. but I’d be worried about cracking later with no paper on the back side there

Why not just go back the next day get 1/2” and tape with some 20 or 45 minute mud?

That is a bad idea. If you remove the paper from either side you reduce the integrity and strength of the sheetrock. It can easily crack and crumble without that support.
Without knowing what the particular application is it would probably be better to shave 1/8” off the structure (I assume wood studs) you are fastening it to than modifying the sheet rock.

Taking the paper off the back creates a perfect weakness for a crack. I would have scraped the stud.

If it’s a small patch in an out of the way place you should be good until your kids inherit the house then it’ll be their problem.

Yep. I did that the other day. I measured the thickness on the edge instead of the end. Thing is, apparently they taper the edge for tape and mud. I also found out the hard way that you shouldn’t predrill the holes for the same reason you leave the paper on… And don’t use regular mud to try to seal cracks. Now I get to do it over… some point.

down the road…..

a piece…

a few months…
...years from now.
