Hi DIY fans Have 2 questions

First, have a plank of wood (about 2 metres by 15 cm). It is about 1.5cm
thick.

I need to scre it onto the wall and I have allocated and screwed out 5
holes on the plank t - which is where I wil lscrew through the wood and
into the wall

Question is what is the ebst way to accuratley drill into the wall
behidn so the holes in the wood match up with the ones I need o nthe wall?

I see 2 options
try and draw out the wood on the wall and hope it is accurate

Use a pencil like device - put it through the hoels and make a mark that
way - problem is no pencil has a tip of 1.5cm to go through the wood and
also the holes are fairly small - is there a device designed to do this?


Secondly, I need soem truning and due to legth I need the best optio
nseems to be self adhesive on a roll. I need to trunk 2 telephone wires
and a network cable - so not too thick

Is this stuff on a roll any good and how to you go around corners? i.e
ones that stick in and out? And what about right angles?

thanks
Self adhesive trunking is easy to put up but IME (I have put Cat5
cabling in a large Primary school over the course of a few years) it
does need to be fixes with screws or masonry nails at fairly large
intervals. The self adhesive element helps to hold it in place while
ypou level it and add other fixings. The adhesion depends on the
surface finish/cleanliness and the brand of trunking. Trunking on a
roll is easier to deal with over long runs and can be fixed with masonry
nails as it is fixed when flat and then shaped.

Cornres have to be done using pre formed clip on pieces with the
trunking capping cut short of the corner - you will see how to do it if
you look at the pre formed pieces. Yoiu can make internal corners by
butting the capping but you need to buy the external corners. I have
used the Screwfix supplied trunking but have minor problems with the
corners as orners seem to be designed to work with particular brands of
trunking and don't fit this typoe easily.
