Hi, how has everyone cut the holes in their dash? I realise that using a hole cutter would be the best way but I have only found a 100mm one for £25
on ebay. Seems a bit much to cut 2 holes!!
Cheers Jay
Car builder supplies do a set of hole cutter/ punches for metal about £50 best bet would be to find someone who has a set other wise its back to
chain drilling and a round file
depends on the dash material.
mine is carbon effect abs.
just chain drilled a load of holes in a circle just less than the gauge then used a file to get it round. didn't take too long, made sure the
hole was tight to the gauge and any rough bits left are hidden by the bezels.

A jigsaw did the trick for me - use a carbide grit blade. 
You can get hole saw sets which go up quite big from bnq for not much money...
bnq about a tenner for a set of 9 or 10 hole saws. worked ok on my fibreglass

£25 is a set of new brake discs - don't spend it on something you'll only use once!
Stitch drill around the inside edge of the hole then take it down to a finish with a file or a dremel, then sand and wet & dry it to a nice edge.
It'll be hidden by the clock surround anyway.
Sorry about the two previous posts - not sure what heppened there!

I got a cheap set from machine mart. Been great. Also useful when ive been putting downlighters in kitchen and cutting back of sink cupboard out for
pipes etc. Defo something to have in your tool collection. Well handy.
Im sure most places will do 2 different sets. One seems to be more electrical work sizes and the other more akin to plumbing from what ive seen.
For smaller holes a stepped cone cutter is handy but cost a bit more.
