You cannot cut or drill heat tempered glass. Not waterjet, not laser, not hot needle, not under water. Physics, not technique. There is no secret formula for cutting or drilling tempered glass. You can do edge work if you are careful, but you are weakening the edge substantially in doing so. IF you don't remove too much glass it may not break. If you ...

"Why is this happening?" The drywall mud was applied too thick "what should I do about it?" Either apply additional thin coats (sanding between each), or scrape it down and start over, this time using several thinner applications and sanding between each

Drywall compound shrinks as it dries, so if applied thick or if it has too much water it will crack. A few cracks on the first coat are ok since later coats will fill the cracks. From the image it appears the first coat here is much thicker than needed. Excess mud on any layer will just mean more work and more sanding later. Ideally the first coat should ...

You have no sledge hammer, no power tools, and it's too heavy to pick up? That leaves you with zero options that do not require or produce an explosion. Besides someone taking it of your hands, which is unlikely, seems to me, the simplest solution to dig a sufficient hole and just bury it.

If it is a nice looking rock or has a particular shape, place it on Craig's list as a free item. I listed four 5" Blue Spruce trees I needed to remove to make way for a garage. Gone over the weekend and I didn't have to lift a hand.

Obtain a chisel with a rubber protector around the top, (more contact points and less chance of hitting yourself.) Proceed to hit this chisel with a rubber mallet or other leverage-providing, hard-ended object. By nature of the chisel's inclined plane, forward motion will cause the rock to crack and split along the business end's edges. Depending on the kind ...

Without (electrical) power tools, or a sledgehammer: Here are 10 options besides a hammer or Fire-setting... mentioned in almost every post (but more specifically, for best results use at least 300 lbs of wood or 100 lbs of wood and 20 lbs of bbq briquettes; let it burn overnight and then (in the morning) dump 15-20 gallons of ice-cold water on it.) Option ...

Yes, you can. You can't exactly CUT a hole, but you can GRIND a hole, if you're gentle and patient. This feller demonstrates grinding tempered glass. About half-way down this page, "sammiesoo" claims to have sand-blasted and ground tempered glass before. This forum also discusses methods for grinding tempered automotive glass. So the answer is hardly ...

If it's in a place that safe to do so, build a fire around it. Let it get very hot. Dump ice water on it. It will shatter. Source: My dad was a farmer and he told me this a long time ago.

I'm going to go with the first comment and say that it's not possible. Tempered glass can not be cut, scored or sandblasted. Doing so will result in the glass shattering. Laminate glass can be cut, tempered can not.

You can. Yes, the tempered glass will completely shatter if this is even attempted. But if you can use a steel needle or stylus absolutely thin and spikes, you can. Then placing a hard wood behind the glass you must use the stylus very gently tapping with a hammer. After a long time, you can drill a hole. Necdet Ekin

There exist expanding compounds like this one: Ecobust, which are poured into predrilled holes and expand as they dry, splitting the stone (or concrete). It does require a power tool, unless there are already some cracks in your boulder, but a cordless hammer drill should be sufficient.

Use a crowbar and put another rock under it so that sections of it are unsupported. Now whack it with the sledgehammer a few times. If you get lucky, it will have a crack in it and you can break it into pieces. Otherwise you can knock off sections from the end. Worst case, use the plug and feathers approach described above. Another technique is to make ...

You can go at it with a sledgehammer (or a smaller hand sledge) and a star drill, and then drive wedges into the holes (or if you are patient, fill the holes with water and let them freeze in the winter.) There are special wedges designed for use in round holes for splitting rock (feathers and wedges seems to find them). ...

You can't. The tempered glass will completely shatter if this is even attempted. If you absolutely must have tempered glass with a hole in it, the hole or any other shaping must be done before the tempering process.
