cutting metal sheet with angle grinder

more speed, less pressure. Let it walk through under its own weight

Are you using thin cutting blades? Are you using a piece of wood as a guide? For very thin steel it might be useful to sandwich the steel in ply, or to have a sacrificial sheet underneath

no. Wd that likely make a big difference?

I tried a guide against the guard but on my cheap tool that tends to flex/move.

I saw some videos where people remove the guard and use a guide against the blade but didn't fancy that.

not very thin: 3mm

Using a 0.8mm or 1mm blade will make life easier (but don't load it sideways)

TBH that's what I suggest if you need a straight edge. Most of the sparks will go downwards but wear safety specs and ear defenders, of course. Do this somewhere that won't lead to a repeat of Notre-Dame!

That should be easy with the cutting blades.

What thickness disk are you using? Mike

At far enough away from where sparks can hit UPVC windows/doors and far enough away from your car :)

Thanks, I'll try that (trusting the Wiki has a section on "Screwing: courage to sticking place).

I'd like to /increase/ the range of the sparks to hit the foxes - one of whom was making off with my gloves when I came out with the Nth coffee yesterday.

During the summer I went into my garden with my slippers on. It had been raining and and they became rather wet. I left them in my kitchen to dry off. Being hot that day the kitchen door was left open.

When I went back a few hours later one slipper was missing. I found it down the bottom of the garden chewed to bits.

For a while the main problem was used nappies being brought into my and the neighbouring gardens.

I do use a thin blade in a circular saw and that works fine.

Yeah, very dangerous if the blade comes apart.

Circular saw with a thin blade would work fine and is much easier to guide.

You'll do better pressing lightly and moving fairly fast - once you've made a slight groove it's easier to follow a straight line. Thinner discs cut easier but are more likely to break. I tend to leave the guards off my grinders because they often seem to get in the way, but I wouldn't recommend that to anyone because they can kick back and send shrapnel flying at you (so don't put your face in line with the disc) or just give you a nasty graze on your knuckles.
