Yes you are right I kind of want both but I can work out the compromise between height and reach if I've got a good idea of the distance between me and the thing.

800 is a bit beyond my budget ! What do you mean it doesn't do height ? Is it that it doesn't do the calc when you measure the 2 other sides of the triangle ? That doesn't bother me really as I just want the linear distance from me (I'll be standing where the cherry-picker will be placed) to...

It looks like there's two versions, the one i'm looking at is the 20m one, the older model I think. 32 euros

Stanley STHT1-77032

I suppose I just want to know do they work at oblique angles before I buy one. I've found a Stanley one for not too much so I'll give it a go. Thanks everyone.

Don't know the height of the ridge, just want to be able to get a "near enough" distance measurement of a chimney from where I am on the ground with a quick method. No necessarily height exactly as it's for a cherry-picker so it's height plus reach combined so a linear measurement from where I...

Do you think that will work if the target is a 45 degree angle to the laser beam ?

So the target is inclined ? Do these laser measures generally have an accurate laser dot or something so you know what part you are measuring to?

I'm sure your maths is good, I wonder if there is a programmable laser measure that could do that calc for me.. like they do the square and cubed metreage... But if the laser can accurately measure to the top of the chimney then I'm good to go anyway, no need for the actual height. Can it...

Thanks for the replys. Nothing that I can just stand in the garden with and point at the area I want to reach? It doesn't have to be strictly height that I'm measuring, just a linear distance between me and the thing I want to get to.

Hi all, I recently guestimated the height of a chimney to see if my cherry-picker could reach and I was wrong by a fair bit. To avoid that happening in the future I was wondering if there is such a thing as a handheld laser measuring device that can measure off an angled surface if you imagine...

Better contact the DNO then :lol:

PaulNorris, a single phase motor is not that expensive and may be the right solution but this is a useful thing to know for me as i will probably be buying some other 3 phase kit soon like a power hacksaw and a planer thicknesser so i am now confident that i can run these things without the need...

p.s. Jackrae, i don't know how to p.m. but i would like an auto start circuit.

i've got a 3hp compressor as well and i've never known of my neighbours having voltage issues. then again my neighbours have got 3 phase supplies. and if we're showing off i've got 2 welders and a plasma cutter! those videos were very useful and have definitely shown it can be done quite...

i envy your box of caps. i collect as much 'scrap' as i can and i've got a fair bit, although i refer to it as 'useful salvage items' to other people but i don;t have anything in the way of caps sadly. i could nick the caps off various motor driven things like my compressor but i would be...

i'd love a variable speed drive but the application doesn't really call for it and i suppose what it boils down to is that i can replace the 3phase motor with a 1phase for about 120 quid but if i could buy a couple of capacitors for 10 quid each and run it without problems i would be happier and...

hi and thanks for the reply. yes it is with a view to actually doing it. it's a 1.8kw and it's got all six ends of the stator coils available. i don't really want the added hassle with a pony motor or the expense of buying an invertor so i am going with the capacitors/inductors route...

hi all. i've read several things saying this (title subject) can be done with capacitors but with a certain loss of power. having said that, the information mostly seems to be american and there are often references to '2 phase power'. at first i assumed it was a mistake on their part...

thanks for your advice, i am now watching a couple of 28mm 3 port valves on ebay.
