Thinnest angle grinder disc

[Broadside]

This job sounds like a good excuse to buy another tool, a reciprocating saw. The tool does all the hard work but compared to an angle grinder moves slowly enough to be very controllable, it will also get in to the tight corners of the frame.

It's not a Flintstones bicycle!

Fred Flintstone always swore by steel bikes. One whack from his club and a carbon would shatter into a million pieces.

im sure Barney Rubble rode a Rockhopper

There's no wobble if you wear the disc down first,or clamp a guide on.The better quality discs are worth paying a bit extra for though.

I've used plenty of Bosch 1mm cutting discs, never seen a 0.8mm before good find!.

I have one of these saws, as for controllable, more control in a classroom of 5 year olds.

Plasma torch? Friend of mine has one - insane!

But the cut is more than 1mm isn't it?

Not sure. When I saw him use it the cut looked pretty thin to me

For the thinnest, straightest cut, how about a slitting saw in a milling machine? Very thin cuts of less than 0.5 mm should be possible. Obviously you need the machinery and someone who knows how to use it. Even on a big machine, access around the seat tube might be tricky.

Such a shame the OP posed a question then ran away, i'm intrigued what he wants to do

I worked for my former father in law making wrought iron gates and railings, and other stuff. He treated the grinder with disdain, having seen a colleague peppered with shards. He would reach for a file or the saw first From what I learned, pay What you can afford for best discs, match the rpm to the motor, and make sure they are dry and in date. Oh, and keep the guard on! Many supposed Safety glasses are also not rated for flying abrasive disc.

Yes very correct
Safety glasses are for dust only
You need a full face visor
A thin disc may shatter
Check its max speed/revolutions on the Disc info
Then check the speed the grinder spins at
You may find some thin discs are not rated for the speed of the grinder and may prove unsafe

Slicing a bike frame longwise and sticking it on the wall would be my guess. He's maybe unable to type with the missing digits and the bandaged stumps

I sat in a guesthouse dining room a few years ago on a cycling holiday, under a lovely lugged tandem of French origin, maybe forties vintage, which had been given such treatment to become "art", and bolted to the wall. In that case it was a real waste of craftsmanship. We shall maybe see

Yup

Years ago I had a "Flying Scot Track" bike, man I knew hounded me for ages to buy it. I finally gave in to him and sold it. Later found out he mounted it above his fireplace and it never saw the outside again.
