Cutting GRP
Well I've not worked with GRP before so I'm not sure what is the best method to cut the hole out in my nosecone
Also if I make a mistake how do I repair the gelcoat?

Slitting disc on an angle grinder. Then tidy up with a sanding bit on a Dremel. Well that's howi did mine. Horrible stuff to cut mind you, make sure you wear a mask
Using above method I didn't damage any gel coat, obviously cut from the gel coat in. |

The method I use on f/g is to mask up the area to cut and mark your lines on the masking tape. Cut the f/g with a cengar saw http://www.cengar.co.uk/pages/e-range-JP901.html leaving about 3mm from the finished line and dress the cut back with one of those sanding rolls http://greens-garage.com/images/drumsander1.jpg working along the length of the cut being carefull not to flick the gell coat off by turning the drum roll against the line. Works for me. have a couple of practice stabs at it in the middle of the panel thats coming out.

Done a search on LCB, general opinion seems to be, Jigsaw with very fine blade, Dremmel, powerfile, some say angry grinder :-(
Just found this, use a jigsaw fitted with an abrasive blade, (not a saw blade). Whatever you chose protect with loads of masking tape. Must pop round one day.

I used an angle grinder with a 1mm slitting disc. Worked fine for me. Also cut from the gel coat surface and a bit of masking tape will help.
Also to cut a perfectly straight line I clamped a cheap steel rule(wilkinsons 40p ish) and cut against it with the grinder. Last edited by SeriesLandy : 24th September 2012 at 10:59 PM. |

grit face jigsaw blades work well, use an old hoover to stop dust going everywhere, i find for afterdark jobs a humdrum hacksaw is quiet cuts well and no chipping if you keep the angle low.

Never try to wipe the fiberglass dust off you with hands or rag Use compress air... |

Dont forget the dustmask and protective goggles , if you can get one of those all in one paper overalls with the hood even better. The stuff is an irritant.

cutting with a short sleave t-shirt on was a bad idea, it does itch a bit!
Good to see another AGM bodied car coming on. I've not cut my nose out yet but did the side and back panels with a angry grinder. Did you get teh AGM side panels BTW?
