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?


Cor! thats an hard question.

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.


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
