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.

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?
