Laser levels How to?

Only in General Practice, when it would cause no end of difficulties.

Or where you also need to match a pattern around the room when papering or tiling.

Hang on, this isn't the Saniflo thread!

Hello Thomas

If you had a permanent one, then couldn't you add a de-algae-fyer to the water, along with some colouring?

You'd have to. Table salt, maybe?

I'd leave out the colouring -- that water will drip somewhere sometime...

I think I must be missing something too.

Surely all you have to do is stand the tripod on something that is 600mm or taller.

But then I would have to be able to get up to that height in order to level the laser ;-(

I've thought further on this and decided the simple way is to use a

Or perhaps a plumb line with the plumb bob tipping the laser dot, a fixed distance could be marked on the line and then use this to set out the upper points along the wall

I was really trying to justify buying one of these laser levels. In the end they are so ridculously cheap I just bought one anyway, just to play with . (Well it is Christmas )

I purchased a £18 model from Lidl complete with tripod and alignment head. My reason for it is to mount a camera on the levelled tripod/head assembly in order to take 360 degree panorama photographs. The picture stitching software works a lot better if all the photographs are taken with the same angles.

I can see its usefulness for DIY - projecting the laser line vertically could help with wallpaper hanging :)

The real problem with water levels is 'stiction'. I made a level using 1/4" bore clear plastic tube which I had lying around, and found it virtually useless as I could get the water to settle anywhere in about a +/- 30mm band. This seems to be due to the stiction of the water to the inner surface of the tube.

Peter should have somewhat better luck with a wider bore, such as a hose pipe, but it will have some residual uncertainty. I would be interested to know if there are any tables (or calcs) that relate length and bore to uncertainty. Well, obviously there are - what I mean is where are they.

Drop of washing up liquid added to the water would probably cure that by destroying (or at least much reducing) the surface tension. Untested mind but that is what I would try but agree 1/4" tube does seem a bit narrow to be particulary successfull.

When I tried it I used a 1/2" hose pipe but still got inaccuracy. Mind you it was a full lebgth hose and I gave no thought to bubbles etc.

Would the addition of some 'un-stiction' to the tubing change things? I am thinking of a touch of washing up liquid here.
