Fencing project

[Borr 5,952]

Well neighbours fence on my boundary has rotted out , they're housing association and the association decided it would be fine to replace a 6' feather edge with 4/5' chainlink , to both of our horrors. It's an absolute abortion of a job they've done , concrete posts at all differing heights and distance gaps underneath and both of us have reactive or dog aggressive dogs . So I've offered to supply and fit 22m of feather board which I plan to do over Christmas , hopefully before . I'm gonna masonry screw some timber uprights to the concrete posts they've thrown in the ground, and as it's quite steep drop on garden I'm going to have to mess about with mitres on the gravel boards and rails , I'm not sure yet weather to screw or nail the feather edge as I've heard different opinions. I've been told not to bother with a nail gun . But possibly a screw gun but my mate used a magnetic screw bit ? Any of the fencing guys input would be appreciated. I've got top rail and gravel boards which I'll probably screw on not sure about top rail either . Gonna watch a few YouTube vids , should keep me busy...
