Cutting Holes in Consoles...
Whats the best method/impliment folks? Planning on using a Jigsaw with a very fine toothed blade.
Any comments/experiences would be welcome!

I haven't done it myself, but from reading the archives here, the preference seems to be a router and template to ensure it doesn't get away from ya.

I'm also using hole saws for the round holes

I'm with Martini on this one, pilot holes then jig-saw and hole saws for the round (instrument) holes. It helps if you put masking tape on the area where the jig-saw guide plates will travel as they can easily scratch the gel-coat.
Angle grinders are also useful for tidying up the rough edges.

Use a proper ceramic/glassfibre cutting blade in the jigsaw, these cut glassfibre like butter and last for ever.
Using a metal blade just overheats it and after it is blunt it basically burns its way through.
Put masking tape all over the area to stop the plate marking the surface and remove when cut finished

Thanks for all the quick replies guys, I've had a look at the "Archives" and I think that some masking tape, a glassfibre blade and jigsaw will be my chosen method folled up with a bit of the B&D wizard!

Yep. i can confirm from experience that a decent hole saw for round holes and a fibreglass jigsaw blade for any otyher shapes. It's very easy to cut fibreglass, with these tools, just make sure you wear a mask and goggles... it makes a hell of a lot of dust.

Adjustable hole saw off ebay for round holes, angle grinder for everything else.

Agree with above, adjustable hole cutter for round holes and jigsaw with ceramic/fibreglass blade for anything else. Because the blade erodes rather than cuts in the traditional sense you can actually edge it slightly sideways to nibble at intricate parts of the cut.
If the manufacturer of the equipment you are fitting provides an electronic template (e.g. PDF) you can print it onto an A4 sized sticky label and stick it in place. You can then cut round the lines whilst the sticker protects the surface from scratches/chips. (Always measure to check it has printed to scale though!)
