Tips and Tricks for fixing 150 x 47mm timber to wall using R-Kem resin anchors?

[DIYknot]

I need to fix a couple of 3.6m long 150 x 47 mm timber horizontally along an outside wall of a house using resin anchors. I've used these anchors before to hang a porch and other things. Every time I drilled a 12mm hole through the wood to touch the wall in order to mark the spot for the 12mm fixing hole taking a 10mm stud.

However one difficulty I had was that if the fixing hole is not then drilled exactly perpendicular to the wall and the hole in the wood likewise drilled exactly perpendicular to the wood then the slight angle of the stud coming about 60 mm out of the wall means it misses the hole in the back of the wood. Not much of a problem with just one hole but when I have to get four or five of them all lined up together to fix my 3.6m length I can't see it going smoothly.

Anybody got any tips for making sure the hole in the wood and wall are both perpendicular so the wood slides easily over the studs?

I did think of drilling right through the wood and carrying on into the wall, putting the resin through the wood into the wall and then pushing the stud through the wood into the wall. But I don't think it would be easy to clean out the dust from the fixing hole or make sure there is the right amount of resin

BTW the wall is made of rough sandstone blocks so I don't even have a nice flat surface to work with using a jig of some sort, it's also the reason I'm using resin instead of expansion bolts.

Is my only option making a bigger hole in the wood and using 50mm square washers or balancing a spirit level on my drill bit?

Maybe.
Stick wood to wall with a couple off small bobs off Stixall or CT1.
When dry drill through.
Blow out dust.
Fill with resin
Nuts on threaded bolt push through.
When set tighten nuts

Fix the pole plate to the wall with screws. Using a decent masonry bit (12-15mm), drill right through the plate and wall. Blow out dust. Squirt in the gear. Put some on the thread too and push in and have a KitKat.

OK, thanks all. That's sort of what I have decided to do. my drill bit is plenty long enough.
