How To Make A Horizontal Level - DIY Spirit-less Level

video How To Make A Horizontal Level - DIY Spirit-less Level
0:05 I cut the end of the ply to create a straight edge.
0:33 Measured 100 mm in and cut a parallel line.
0:46 Because the piece I wanted to keep was not under the rail, that side was not square.  I have come to realise that this rail saw isn't particular good because it doesn't have a riving knife.
0:54 Checking the accuracy with callipers.
1:02 I check the edges with an engineers square and realised that the first cut was square but the other wasn't, so I marked the side which would become the base of the level.
1:13 Square of the edges keeping the flat side to the fence of the chop saw.
1:25 Find centre of material and mark a 90 degree line from bottom of level using engineers square.  I also scored the lined to make it visible.
1:48 Drill a hole for nail.
1:58 Cutting thin pointer which will have a pin hole at the top and a point at the bottom which should be made exactly central to the edges of the ply.
3:36 Loosely nail the pointer to the horizontal along the centre line, so the pointer swings freely.
3:48 When the pointer lines up with the drawn / scored centre line the object is level.
4:15 The shared studio workbench is not level so I took it upstairs to check ours out.

Nice work, you can't argue with physics. As long as everything is square, and there is no resistance in the pointer that will be perfect every time. For vertical lines I'd always use a string line, I'm a decorator so use one all the time for hanging wallpaper straight.
