100mm hole saw
Hi all,
I'm after a 100mm hole saw so I can put my clocks into my nice new carbon dash. I don't want to chain drill as I can see me bodging that
up and the hole saw makes a much better job of it. I've had a search round on the web and I can't find one anywhere.
If somebody has one they could lend me even better! I only want to drill two holes.
Thanks,
Dave

What material is the dash made of?
If it's GRP or wood then these things are quite effective:

I have seen them cheaper than this though. Warning - they're quite scary to use - you REALLY need to keep your fingers out of the way!

don't be a girl, chain drill it. 
mask off and cover the dash so it is does not get scratched.
you could even make a hole drilling jig and place it in place so there is less risk of drill slipping.

I've got a 102mm holesaw and tried it on a bit of scrap, but the clock doesn't sit right in it, those 2mm seem to make a difference!
If it was a lump of GRP or MDF then I would chain drill it, but carbon fibre ain't cheap and one slip and it's going to look a right old
dogs dinner.
Cheers
Dave

a hole saw can slip too!!
if you have a drill press, then you are less likely to have an 'accident'.

Dave - carbon is no more difficult (if not slightly easier) than grp. The dust is nasty however! I would opt for the chain drill plus file approach. I
cut out the shape of a Koso gauge (that is a pig of a shape) using drills, a Dremel and some files, so you should be fine!

I went to my local tool hire shop and they ordered one in for me, although i used a 98mm one.
