Trunking and making holes

[mo]

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

Cor! thats an hard question.

Line the wood up to were you want it,hold it there and drill straight through one of the holes in the wood and into the wall. Then put in a rawl plug and screw the wood onto the wall,then drill other holes whilst keeping the wood firmly in place against the wall. If for some unkown reason you don't want to do it this way? find a thin round bladed unused screwdriver and file its end to a sharp point and use it like a bradawl.

Assuming that you are using plugs and screws rather than frame fixings

I would offer up the wood to the wall in the correct place and drill through the centre hole with a suitable size bit either masonry or ordinary to mark the wall behind

Then remove the wood and drill and plug the wall with the correct combination of masonry drill size and rawlplug

Then screw the wood to the wall and use a spirit level to get it either horizontal or vertical (assuming that it needs to be one or the other)

With the wood in place mark the other holes in the same way as the first

Loosen the screw and move the wood to one side and drill and plug the other holes

Position the wood back in the correct place and insert all screws

If you use frame fixings instead you drill straight through the wood into the wall with the same size drill and put the frame fixing straight in through the wood and tighten

Not really, use a drill bit that fits the hole loosely, get the wood in place, dab the back end of the drill bit in shoe polish and poke through the holes.

That's the quick way, for a more perfect job, drill plug and fix to the first hole, level wood and mark last as above, drill plug and secure then mark the other intermediate holes as above.

Frame fixings make this easy.

Working in a school part time we have to fix sundela board to walls on a regular basis to satisfy the isatiable appetite for display boards. We do this. Drill 5mm hole in the top centre of the board Hold board in place on wall and drill through with 5.5mm masonry drill to suitable depth Tap red plug in to hole in board until flush, then use 4mm screw as a drift to push plug through board into wall. Tighten screw Square up board and repeat as necessary

I ave also used this technique to put p battens for heavier jobs. It helps if you can find plugs with no lip on the front

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.

Simple. Buy a 6mm Bosch Multi Material Drill Bit

the wood & drill right through wood & wall in one go - at about mid point. Insert hammer fixing and whack in 90%

Level the timber & drill & fix as above at top or bottom. Check level, insert other 3 fixings as above.

Stuff can be bought at B&Q if you don't have a Screwfic depot handy.

Those thigns in your second link - what are they exactly? like wall plugs but you can just hammer them in instead of screwing?

Absolutely - Hammer Fixings. Same size drill goes through timber & into wall, insert fixing, bash with hammer. The plastic plug stops flush with the timber, the 'screw' carries on to open the plug.

The screw head is for removal. Just make sure the drill is long enough.
