pocket hole in lath and plaster
I really messed up!
I decided to replace the old recessed TP holder in my bathroom with a new one. After removing the old one I realized that the hole in the lath and plaster wall would be too small for the new holder.
Using the provided paper template and a borrowed jigsaw, I drilled holes in the three new corners and then proceeded to use about 10 saw blades to cut through plastic tiles, top-coat and then the lath and plaster (each blade lasted about 1.5" inches before getting ground down by the ancient plaster).
Well, at the end of all this, I have a larger opening but I didn't stick to the template perfectly and the opening is still about 1/8 inch too narrow.
I tried using the jigsaw to cut a thin strip off one side, but it just mangles the plastic tiles and throws chunks of plaster. I also just can't control the saw very well on such a thin cut. I'm afraid I'm going to lose a finger!
How am I going to get this hole just a little bit wider?
I don't know what to do. Any ideas? TYIA.
