[bob]

right I have got hold of some smart top secret hush hush bonnet vents for my nova and just need to bring myself to cutting up my bonnet(its ok got a spare tho) just dont know how to do about it :( do I drill a hole then jigsaw or wot? wot blades n drill bits do I need if so? thanks in advance peeps!

When I do anything like this I just use an electrical drill and electrical jigsaw.
I think Youve got the idea, mark out with masking tape where you want to cut, just drill a hole, make sure that its inside the area where the vent will be (ie on the bit thats not needed) and make sure the jigsaw blade will fit through the hole too.
Then just cut away, I got some metal-blades for the jigsaw, you can get them everywhere, B&Q etc sell them. They dont last that long when cutting large areas tho, I used one up when cutting my wheel-well out to give you an idea!

when i cut my bonnet to fit my vent i just marked out the area with a crayon and then used an angle grinder to cut out the whole. You will get a lot smoother finish but you might need to finish it off with a small file though. Good luck

it might be woth going round the area ur cutting out before hand and scoring a line into the paint cos i had a mate, who whilst cutting with a jigsaw, lifted all the paint around the cut and it turned into a big job.

Careful cos dan16v put a gsi scoop in his bonnet and slipped with the jigsaw across the bonnet only a little scratch but it showed up !!

re going round tight corners use a "scrolling blade" - small skinny in width and can turn corners on a gnats arse! Also make sure that when you are cutting you look out for any structural supports under the bonnet and bare in mind that you need to cut through them aswell (make sure yer blades are lonng enough) Just dont push too hard when cutting.
