I have a wonderful level I bought in England nearly 40 years ago for only a few dollars, a rectangular bar about an inch wide and half an inch high with a channel milled the length of one side and a post attached at each end of the channel with a spring attached to the post. There is a rod connecting the top of the posts and a ball bearing about three quarters of an inch diameter runs in the channel constrained by the posts and bar above.
Sometimes it is necessary to give the ball a little flick to overcome inertia, if it has a fault it is too accurate. I keep meaning to machine an accurate long arrangement so I can place this level on one end for getting vertical measures and maybe a hinged piece to be set for specific angles but it seems my life is chuck full of unfulfilled intentions. I once borrowed a device which was a curved piece of heavy plastic I think attached to a flat stick with a pivoted pendulum weighted at the short end. The tip of the long end protruded a little distance past the ark forming a pointer on a protractor and the arc had studs installed at intervals, don't remember just what intervals. There was a sprung button you could press and hold to keep the reading, that could have been better, maybe a ballpoint pen type toggle would have been better because it was awkward to hold this while removing the level and examining the reading. The other problem was that who ever was selling it wanted something like two hundred bucks for it. Technically, both my ball bearing level and the one I just described should be on longer trusses or come with longer ones for better use. A builder really wants at least a four foot long level otherwise you are picking up small imperfections in the material not overall level. If I had a couple thousand spare dollars I think I might just make a couple hundred improved versions of the pendulum style, surely even on that small of scale of production one could get them out under 20 bucks!
