| vial for a machinist's level |
| << < (4/7) > >> |
| Will_D:
Lets get to basics on this: A bubble level consists of a tube with yellow liquid* in it, a bubble, and some lines for reference. A straight , in-line tube will not work! However, bend the tube to a slight radius the you have a bubble level! The radius defines the accuracy. So the most accurate and hardest to use would be a straight tube with a bubble! ! *Yellow is usually Fluorescein in water! |
| Pete.:
Carpenter's levels might use bent vials but machinist's precision levels use ground vials. This place does reasonable priced ground vials. https://www.leveldevelopments.com/products/vials/ground-vials/ |
| Will_D:
"Ground" in what way? |
| Pete.:
Ground internally to a slight barrel shape, to produce a level that is a measurement device rather than just a levelling tool. |

Pete I did get in touch with LevelDevelopments back when I was first trying to find a vial. They were able to suggest one of theirs however with shipping the cost was not viable. They appear to have a very good selection of vials and were very prompt to deal with. If I had really needed the vial and had no other choice I would have been happy to deal with them. I did pick up a large (about 24 in. square) piece of acid free white paper today at an artist supply shop. It was the thinnest of the acid free paper they had and I hope it isn't too thick. They had cotton based acid free paper but it was even thicker. Will soon see when I get the vial. John. |
