vial for a machinist's level
PeterE:
jcs, here is the build thread on how I made my engineers level. Hope it is useful.

Don't know how I missed that - nice job. Did you ever modify it so that you could set and reset it easily?
Thanks for the link to college engineering however I think the vial you used has too small a diameter. The id of the tube of the lufkin is about 16.8 mm so I suspect I need one around 15 mm in diameter. I've sent a message to this outfit to see if they have something suitable:

Thanks,
John.

John, if you mean that I can set it for angled measuring and then reset it to true horizontal, yes I can. The spacers below the fatening screws can be exchanged for washers of different thicknesses f ex nad then just put back the basic spacers to get back to horizontal level.
You are right that my vial is kind of thin, but I found one with good precision tolerances at a local store and as the vial is set in plaster of Paris it works well anyway. My tubes inner dia is smaller than yours. Found drawings in an old copy of MEW (Model Engineers Workshop) for the one provided by College Enginnering, and had a suitable piece of scrap to hack into so ....
Works a treat.
Hope you will get yours in good shape as well.

I just received a reply back from leveldevelopments regarding a vial for the level. It must be a very nice vial as the cost to me including shipping would be more than it would cost to buy a good used 12 in. starrett level. They replied quickly and efficiently so I give them full credit for that. So that avenue is out.
Will look around for other sources - perhaps I can find one for a 12 in. starrett as it may be a bit more reasonable. At least I'm in no rush!
John.

The whole point of this thread is about the vial!
Following the above thread link lead me to:
"see: http://www.collegeengineering.co.uk/SpiritLevel.htm"
Now a spirit level vial iirc is "just" a bent piece of glass/plastic with flourosceine dyed wate, a bubble and some etched lines"
The more expensive the vial: Then its a much larger radiius with longer space between the grad.lines!
