OK here goes,

silly question time. I am about to start running brake lines from front to back and wondered how on earth do I drill the inside of the tunnel to mount the P clips as the tunnel is not too wide and getting a drill in there seems almost impossible. I have not tried to punch a starter hole yet but any advise welcome....

Use a Dremmel to drill them maybe. 90 degree adaptors help at times for your normal drill

Presumably the tunnel isn't panelled yet?

Can't you drill at a slight angle with the back of the drill sticking out of the opposite side of the tunnel?

Alternatively get a flexible or angled drill shaft.

Stu

Using a right angled drill is one (preferred) option or drill at an angle with a conventional one

It isn't easy, you are correct. Dremel, and 90 deg attachment will help, also careful choice of where you put the holes.

Make sure you do it well though (correct spacing of fixings), as you don't want to try it later when you have a propshaft and side panels in. Don't ask me how I know how difficult it is.

If you have a compressor an air drill is a lot more compact and easier to use than a 90degree attachment IMO.

Try one of these

A bit cheap and nasty but it will probably last for the job

Screwfix do a good quality 90deg adaptor for your drill for about £20, I have one and its very useful.

You need to centrepunch where you want to drill anyway, that should be enough to stop the drill wandering when starting, then just drill at a slight angle if using a normal drill.

I ground down a drill so it only stuck out of the chuck about 3mm and then used a 90deg adaptor.

air drill or 90deg adaptor. dont bother with a dremel they have to be run at too higher speed as they have no low down torq which kills drill bits in seconds

I've got the screwfix 90 degree one.....

browed 90 drive like in the e-bay link to do that job; worked fine..

or plug weld on little 90 degre tabs? should be possible to get the torch head in the space availabe.

should ever need to remove the line, then you will not need to worry about the rivet heads rattling in the chassis tube.
