chopping a fender

ok so bear in mind that im learning as i go along ok?
chopping a stock fender down:
is it basically a matter of putting a cutting disc on an angle grinder? bring the wheel down onto the metal surface, sink it in, drag it slowly along the cutting line?
anything I should be aware of?
im guessing it's best to establish where I wanna chop the fender with a masking tape line.
how rougher edge is this likely to leave? tidy up with sanding disc, file, etc?

Practice on some scrap sheet metal first Brett, The 1mm thick discs are awesome for this I usually find it easier to let the grinder draw your hand along rather than drawing the grinder if you know what I mean. Gloves and safety glasses are a must and don't put any side loading on the disc while it's cutting or you'll end up with a face full of disc.
Practice Practice Practice then when you feel confident enough CHOP THE SHIT OUT OF THAT FENDER. oh yeah a file should clean up that edge just nicely.

cool, thanks

I always use an electric sander to tidy up rags and burs left over from the cutting.

If you're shortening only, it's worth measure from the end of the fender to where you want it, and mark it... and keep doing that until u have an accurate line.

Measure tape used by tailors is good for that.

yep, good stuff, thanks m8

Just cut that sucker! But a word of caution.As woody says use that safety gear,especially googles! I was cutting the rear fender on my trump bobber last weekend,with safety glasses,but had a fragment melt into the lense of my eye. :affraid:Shot up underneath my glasses. Spent 3 hours in A&E as they dug it out.But that fender looks shit hot!
