drilling through walls

[jase158]

does anybody know of a gadget that will tell me exactly where to drill through walls, to get a straight line through the walls, I am thinking of something similar to a pipe and cable detector.

but will go through 300mm or 400mm walls.

scenario 1, drilled through wall but no access from inside, so went diagionally, cam back straight. ended up having to relocate condensate pipe as pipe too close to condensate.

scenario 2, had to get a soil pipe through a roof space that was around 1.5 metres, no access to loft space, had to estimate fall.

on both occassions i could of done with a starting point from outside as to know exactly where my hole was going.

perhaps magnets or sensors would be good.

usually a tape and a level is sufficent to tell me where to drill some times you just have to offer up a prayer to the god of plumbing and go for it
there are devices that would allow you to pin point the spot to drill but they tend to fill a small lorry and cost thousands
must admit ive thought the same over the years and no doubt it will come eventually
the ending up to close to what you want to connect scenario is part of the learning curve jase always try to give your self room to maneuver

there's no use praying to me.

I always drill a small diameter pilot hole first to mark the centre of where the hole is to come out. Tool station sell 1metre long drill bits. At least a small hole can be filled in.

Cheers for that system. The simplest ways are always the best.

Not at all, it's me what is simple for not thinking of it all by myself.:6:

Your quite right there you can't even install a bathstore tap......]

Couldn't resist it, I'm still amused by this.

Now, now kiddies let's all behave like big grown up jobby mechanics like we're supposed too.
