How to cut pipe squarely using an angle grinder

What you're describing is just inexperienced workmanship. You did a guillotine cut, like you would saw through a piece of wood. A better plan would be to use masking tape wrapped around it to ...

Can a freestanding pool's poles be cut to accommodate sloped concrete?

The problem with cutting the poles is that the liner that goes inside won't fit like it's suppose to. Where the "shorter" poles are, part of the sides of the liner will be on the bottom of ...

How can I shorten a reciprocating saw blade?

I just save my broken blades for this. Clamp it in a vise, where you want it to break off and hit it with a hammer very sharply. It should snap off (make sure the part you want to KEEP is in the vise)...

Can/Should I use an angle grinder with a blade for metals on PVC coated metal?

I think you'd do better with a Sawzall. That's the trade name - like Kleenex, everyone uses the name no matter what the brand. Just looked up - it is generically a reciprocating saw. These things can ...

How can I shorten a reciprocating saw blade?

Use pliers or vise grips to grab the blade on each side of the line you marked for the cut and just wiggle back and forth. Metal fatigue will cause the blade to break. This works better on stiff ...

Can/Should I use an angle grinder with a blade for metals on PVC coated metal?

Can/Should I use an angle grinder with a blade for metals on PVC coated metal?

A circular saw with a common carbide-tipped blade will make quick work of it. The steel in such frames is soft and will dull your blade only slightly, if at all. Otherwise, just knock it apart at the ...
