I have to repair the cork backing of some built-in books shelves.
It has 2 layers each about a half-inch thick or more.
How do I cut the cork?
I'm figuring the new cork pieces can be cut with a band saw?
But what about the cork that is still glued to the wall, but is
raggedy. Does anyone know a good way to cut it in place, so I can
install patches? I don't think it will cut with most sharp knives,
from prior efforts to cut cork. (Mice tore off about 3 inches by 10
inches, and shredded what they tore off, until they lost interest.)
Probably not. Why would you even try? Use a sharp knife and a
straightedge. Lay the cork down on a board or scrap of plywood
(something wooden that you don't care about), lay the straightedge on
top of the cork at the cut line, and slice through it.
Cork cuts just fine with sharp knives -- if you've had trouble with that
in the past, then your knife wasn't anywhere nearly as sharp as you
thought it was. "Sharp" in this context means razor-sharp: if you can't
shave hairs off the back of your hand with it, the knife is *not* sharp
Let me reinforce what Doug wrote, from personal experience. I had to
cut some cork acoustic tiles, and saws are messy and tear at the cork
no matter how fine the teeth of the blade. I haven't tried a rotary
tool, but I imagine it would be the same thing. Remember, cork is soft
organic, so it's going to shred easily.
But I used a fresh Xacto blade (and a friend used a fresh single-edge
razor blade) and it sliced the cork beautifully.
I'll buy that. OK, I"ll make sure I'm using a new razor blade. I have
noticed that the ones that use single edged razors seem sharper than
the Wiz knives and similar ones with the thick trapesoidal blade. But
I guess it didn't sink in yet.
They used to sell on late-night tv tools that used actual double edged
blades meant for shaving faces. I figure they were too good to be
true, and that all the demonstrations in the ads were done with balsa
wood. Has anyone ever used on of these?
Thanks and thanks to all who replied.
Yes, that's because the single-edge razors are honed specifically to make them
sharp enough to shave, i.e. razor sharp. Utility knife blades (the "thick
trapezoidal" ones) don't come that sharp from the factory, but they can be
made that sharp pretty easily: Google the phrase "scary sharp" for more info.
