Dave BC,

A good quality engineers level should be able to give you an accuracy of 0.002" over 3 feet, or 0.05mm over 1 metre,
or approx 1 in 20,000.

A builders level is just that, good enough for putting up a building, but no use for precision stuff.

Not sure CC, but for some reason I believe you live in W.Yorks. ?

If that's the case, you are nearer to any more than me, I got 'em near Hebden Bridge ..

Thanks for info. on accuracy.

Nice to have some idea of their limits.

Just had a quick go at the 4" one on a surface plate, propped up to get the bubble dead on the fiducial.
Crack on both ways  :D Even with a small hand lens, I can see no error.

Big one has some edge dings, will have to bevel the edges by about .5mm  .. this OK ??

Can't see any reason not to .. there is plenty of cast iron to sit on, about 3/8" to the central groove.

Dave (BC), I'm in Wakefield  , not a long way from Hebden Bridge, but I imagine the car boot sale is over by now   :bang:

Nice find though  :thumbup:

So sorry John!
I hadn`t spotted you were booked to explain......  ::)


I gave one of those levels away the other week. It had been hiding in my toolbox for most of a working lifetime.

It`s now hiding in another forum member`s toolbox......  :thumbup:
