Furnace bump timer

A utility knife takes about 15 seconds start to finish. The scrap is in a couple pieces and is easy to clean up without power tools.

You can't fix stupid. You can't even put a band-aid on it, because it's
Teflon coated.

Pop a 5mm drill through in each corner ! FWIW there is a plastic template available for single and double gang drywall boxes.

So, the filleted inside corner created by the drill bit limits the stress rise as compared to a sharp corner or a corner that has a chipped - out back side?

I suppose this would reduce the likelihood of a crack forming, as during an earthquake for example.

I see your point, Baron. Good Idea! Thanks!

If he ever tried what I'm talking about he would find that you can cut more than half way through drywall with a utility knife. Done properly, it continues in a straight line, leaving nothing but paper to cut but he can waste as much time as he wants.

Thats the idea. Those templates I mentioned. I just looked at mine. Its actually an

8mm drill (supplied) and has a series of guide holes (imagine figure of eight but square sides) every few mm. It also has four very small pips or pins on the back to stop it sliding about whilst drilling. A quick tap with a hammer pops out the blank (sometimes). The biggest problem I find, is the cardboard honeycomb in studding, sticks to the waste and makes it awkward to remove.

That's how I cut 'repair panels' to size. Score, snap and cut the backing through to separate the pieces. It works great and results in straight cuts. No 'inside' corners, no issues.

On the "Home Improvement" TeeVee shows, I've seen them use a "drywall saw," which looks like a small keyhole saw.

Cheers! Rich

I saw a "drywall saw" once, but it looked just like a hammer...

Yse, they have tto use every gadget. They also have a nice wet/dry shop vac to clean up the plaster dust.

I see your puny hammer & raise you a 20 LB sledge! :)

Their fine for shaped holes even though they rag the edges of the hole.

I broke up two dump trucks full of old concrete with that hammer in a couple days when I was 30. it took the county longer to load the trucks than it took me to bust it apart. Adrenaline can do wondrous things, if you don't let it kill you. :)

Using a backhoe is cheating, BTW. :)

And stir up enough dust to choke a horse.
