Hi
I've rebuilt a short section of sandstone wall at the front of my cottage but both of the matching stone gateposts had previously broken just above ground level. The stubs appear to have been dug out and disappeared before I came here. I'm OK with setting them on concrete plinths (or suitably shaped stone if time and budget permit), which would only have to be showing 10 -20 cms above the ground. Best received knowledge is that I should have a couple of M16 s/s threaded bars joining the post to the plinth, plus resin between the surfaces. But how does one drill the holes in exactly the right location in the plinth to match the bars in the base of the post, or vice versa? I would like to be able to hang a gate between them.
