I've always used an angle-grinder with a thin cutting disc... wear a mask - the dust will cover you and everything in sight!

I found a thin diamond tile disk made the least mess and neatest cuts... it seems to melt its way through rather than tearing

dremmel type tool with either the cutting disk or a router / drill bit as said wear a mask

I do it by hand, put some masking tape on the area your cutting, mark it out then use a junior hacksaw and a file or two too finish it off!

Unless I missed it you didn't say straight or curve?

For curves I like a coping saw from the gel coat side, with a good sharp blade.

I did my boot box with a jigsaw and a fine hss blade. Worked ok, do it outside if you can, dust goes everywhere and makes you itch.

I always use a jigsaw fitted with an abrasive blade, (not a saw blade). Tape well with masking tape so the saw dosen't mark whatever your cutting, and the jobs a good un! HTH Ray

1mm cutting disc is by far the quickest, easiest and most accurate (once you get the hang of it) I used to use a carbide jigsaw but it was too violent and the cutting wheel just glides through - you can even do gentle curves if you just use the edge of the wheel.

diamond disk for straight cuts, hacksaw or coping saw with masking tape for curves, air saw with a hacksaw blade or fine jigsaw works well too.

that's what i used and it went perfect!

i'd use the dremel only for detailing.

another Dremmel fan here. Did all mine with a dremmel and finished anything with a file.

Mask and safety glasses essential. The little dremmel cutting discs tend to shatter is abused to much.

I used an angry grinder with a cutting disk. Went through it like a knife to butter

Angry grinder, with fine disk.
Basically anything with small teeth that won't cause it to delam.
Also a mask is NOT optional, you don't really want to be breathing this stuff. Or getting it on your skin if you can avoid it, it itches like buggery.

Do a search! This has been covered so many times!

Alternatively, use a coping saw, it's a bit slow but dust is minimal and accuracy is very high. A lot of necessary cuts on nosecones etc will be curved, too, so angle grinder not much good.
