as i have a idea for a project but never take a tape measure along with me when i am out on summit
if anyone has this info or if they can point me in the right direction(excuse the pun) as to where i may get such details tried ordnance survey but they never got back to me
I might be wrong, but I don’t think there is a standard size judging by the ones I have seen.
The only standard seems to be the three legged slots in the top of the trig where the measuring instrument would sit.
I’ll stand corrected if anyone tells us differently.
In reply to M1MAJ:
The telegraph article is very good.
Not only does it give the approximate size (if you fancied making your own) but also answers the question of how they got them up there in the first place. Did they take them ready constructed or build them on the summits?
first may i say sorry for the delay in getting back to this post sooner but been ill
Anyways may i thank all who have got back to me with regards the size of a trigpoint & the weblinks many thanks
so its 4ft high and 2ft sq at the base. Now i wonder what size the top is as it tapers off from 2ft sq to what size i wonder(Measure tapes now being placed in backpacks hi )
the reason iam asking is iam thinking of a small bracket style mount
I’ve made myself a little widget I find to be very effective - simply a piece of 100 x 38 timber about 100 long with a notch cut in one side and a taper planed onto the other - if I remember correctly the taper is about 1 in 7 for a standard trig. The corners on the side with the notch are cut at 45 degrees.
Place the widget against the trig point about 1m up, locate the pole in the notch with bottom resting on the ground, use a small-sized ratchet strap to clamp the pole to the trig point, position it just below the widget and it will hold the pole firmly in place. Set it up on the side oppsite the direction of the wind so the wind pressure tends to push the bottom of the pole inwards.
In very windy conditions a rucksack or stone (found locally - I don’t recommend carrying your own rock up the hill) ensures the bottom of the pole stays in place.
Works a treat, sets up in seconds. Anyone want to start manufacturing it commercially? I’m open to offers for the intellectual rights to the design!
If you’re confused by the description let me know your e-mail address and I’ll send you a sketch as an attachment
OK, I could not resist, so I have just had a stroll with the dog up the
hill at the back of my house to the local trig point.
On this trig point which is the regulation 2ft square base, 4ft high
structure, the top square has sides of 15.5 inches. Seems a strange
dimension, but that is what it measures HI.
