Needed to trim back the slates along the edge of the roof by an inch
after removing the rendering on the wall below. Bought a Wickes 1000W
125mm AG, does the businness but it is eating stone cutting discs
(non diamond). I bought three thinking that would be one and two
spares...

I'm about to use the last one. I've cut about six linear metres of
approximately 5 mm thick roofing slate, mostly double with the some
triple thickness. The lower layers I'm not cutting right through just
making a score and snapping off.

Is that rate of disc use about right or am I doing something wrong?

Aldi, cheap diamond sets. Finish isn't terrific, but they cut and
last pretty well.

Get yourself a diamond. Even low end ones outlast many many grit
discs, and they perform better, and are safer.

Thanks guys, I just about managed to finish what I needed to do
before the last disc was worn out and that was doing even more score
and break that I had previously.

Probably becasue real slate is quite soft ...

Well thats what I thought as well in only buying 3 discs to start
with. If I'd been cutting through brick or real stone I'd have
probably bought some diamond blades as brick/stone is 'ard compared
to slate init...

However, treat yourself to a diamond blade and marvel at the difference
in longevity and performance!

I will now! Unless you are cutting something really soft, like
mortar, I can't see abrasive discs being any use at all.

AIUI diamond discs wear faster with soft materials. I still use grits
at times, diamond isnt best for everything, especially on HSS.

Couldn't you have just put a wooden batten under the gutter brackets?
I'd have thought the further out you could take the water, the better.

Gutter? This is along the tops of a gable. B-)

Barge boards would be used on most buildings but anything that the
wind can even remotely get behind will be ripped off(*)... Slates
trimed to just proud of the rubble stone wall and mortared over.

(*) We get 40 to 50 mph sustained winds at ground level and there is
a considerable difference between exposed ground level and chimney
level, as I had found in the last few days. I wouldn't be surprised
if wind speeds at chimney height can be 50 to 60mph sustained, with
gusts 10 to 20 mph above that...

I also would suggest Aldi, cheap and cheerful but it works. I bought mine to
cut up thick church paving slabs followed by tree roots still in the ground!

Fit a wind turbine.. then the winds will drop.
