Dont fancy another go with the arm type after one bit last night and nearly broke my hand!
Think its going to have to be back to the old fashioned tried and tested way of loads of little holes and a file
I need to some large holes in the dash and rear wings.
What are people using to cut similar holes lights gauges etc
A drill attachment, its got a sharp point in the middle that you put in a pilot hole, then has an arm coming off it with a sharp edge, you can adjust
the length of the arm to change the diameter of the hole. They are a bit scary as in a normal drill they spin fast and have a bit of weight on one
side, but can make a nice clean hole without too much hassle.
I got mine from a show. I think you can get them from car builder solutions, im sure a google will bring up their site.
Hole saws. I think thats what greggors84 is talking about?
Hole saws can be bought of all sorts of suppliers like machine mart, local tool merchants or auto jumbles.
Greggors is referring to a tank or fly cutter (depends who you talk to as to what they are called). They are OK but best used in a pillar drill due to them only having the one cutter.
The holes in the rear wings are awkward because of the slope if you want something round to fit into them. Best to cut a tube of the right diameter at the angle required and draw round it. It'll look nothing like a circle.
Cheers guys for the replys.

On the flat hole saws, with a drill bit in the middle and the varoius diameter saw toothed attachments, are usefull tools.
A good set can cut through most materials including steel.
typical hole saw sets are good for a range of holes from about 5/8" to 6" depending on what cutters you have.

circular holesaws are fine, and you can run a bit of angle with them if you are careful. So long as the pilot bit gets embedded before the teeth start
to bite. Just hold it firmly and go steady. A good cordless is maybe easier than an electric drill turning too fast.
Any electric dill corded/cordless woth its salt should have infinatly variable speed from 0 to its max.
long time since ive bothered with an electric drill!
When your putting about a thousand self drilling screws through RSJ's you don't even contemlate cordless drills. Unless you are buying half
a dozen spare batteries and a charger for each battery.
both types have there time and place.

Impact screwdriver?
The sort of impact srewdirvers I know of are designed to remove stubbon screw etc. and needs hitting with a lump hammer.
Not the sort of tool needed to drill a hole.
A normal drill seamed to work a treat with a magnetic socket in the chuck to hold the screws.
I found an Air screw driver gives best control

I've just done the dash and rear end and found that a compass, drill and a jig saw did the trick a treat. Provided you don't want to go too
small.
The smallest i went was 50mm diameter
