Use the steel wool as backer for caulk. Fill hole with caulk in two or three built up layers, let each set a while B4 next, a big one shot blob may fall out. Any good quality paintable caulk that will adhere to stone and wood will do.
"steel wool, leaves a bad taste in" my mouth too. I find that if i drench it in jalapenos and cheeze whiz it is a bit more palatable.
Measure twice, cut once.
Look at the nail, not the hammer. Watch the fence, not the blade.
If you hook your thumb over your belt you won't hit it with the hammer or leave it layin on the saw table.
