I love my laser. Recently bought a laser level to hang some shelves. A fairly cheap one about 150mm long by 30mm square. I was wanting to find a centre line on the inside of the hull of a Dark Biter MTB I am building. The only flat area on the hull is the transom. So stood the hull on the transom , marked the centre and shone the laser up the hull to give myself a centreline inside the hull. easy peasy. I'll also use it to mark the waterline. Ain't technology wonderful.

Now why didn't I think of that !    I've got one sat in my toolbox and I've been putting the waterline on the old fashioned way.... must engage brain

Artistmike I like your Bernard Shaw Quote. Personally I never wanted to be a groan up so didn't do it.

I'm a bit confused now. What kind of laser level are you using? (just Google laser level if you wonder why I ask) I'm trying to visualise how with the boat stood upright a level can give you a centreline as that would be vertical not horizontal.
Is it just one that has a single beam shining out the end to give a point of light? Or is it a 'scanning' one that draws a line of light across an arc (and maybe can do a vertical line too)?

Just looked it up on internet. It is a Bosch PLL5

Just looked om Amazon and saw this   How does it stay on the wall?

Peter,

If the wall is of metal studs, then a magnetic base holds it there, if not a suction type base.

However it would need to be accurately leveled before turning on the beam, otherwise the items, in this case speakers would be in line but not level.

A point to remember when using a level is that the longer the bubble holder and the longer the bubble within that holder the more accurate is the level.

Also to check accuracy of the level, reverse the direction and the Level line should align, if not the level is inaccurate.

There are a pair of pins that hold the base on the plaster wall. The laser has a pair of magnets that hold it to the base.

Hi raaartygunner metal studs where not used in older houses in in uk and I don't know how often they are used in new builds I know they are used a lot in the states, so where essex2visuvesi lives  it may well be  Witchcraft, they let him move there   

only kidding

Never, ever, thought of using this technology for marking a waterline.......I'm in a bit of trouble with the odd shape of the stern area of the Admirals barge......could you please expound a little more on this? Cheers. BY.

My laser level is a 5 point laser and also self leveling
up down left right forwards
I cover any not in use with tape
It's a little over hand sized ...... but not as big as HS93's No2 wallet

Have a look here Bryan: http://www.modelboats.co.uk/forums/postings.asp?th=71903&p=2

The pencil method can be a bit inaccurate where you have tight vertical curves on a hull. The laser method helps overcome this. Wish iId thought of it myself.
