Apologies if this is a bit long .... looking for some advice on plug & screw fixing. I have a large quantity of raised garden beds ... so effectively a 100 wide brick wall. On advice here - I will be fixing 5mm plastic spaces to maintain an airgap (keep wood off brick) ...... end result will be:
Also on here have purchased 152 x 7.5 concrete fixing screws
I will counterbore holes so I can glue in wood plugs ... intend using router to do this.
There are 2 approaches ...
Fixing option A
Or I simply dill in at 90 degree to surface of angled section - meaning fixing will be angled. Fixing option B
This 'may' give a better fixing, and would mean no jig needed router would go flat on sloped section. Welcome thoughts on this.
Secondly ....... Screw is 11.1mm across head ......... so need to counter bore to 12mm (or 1/2")
Option would be to use either a screw digger:
with plug cutter:
not sure if these would be any better:
Welcome advice from those that have used these before.
