  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

Indexing on a lathe

Came upon a unique use for a digital level. The picture speaks for itself.

That's brilliant.
I saw a similar idea using a bubble level but it was not as convenient because the level wasn't magnetic.
 
I did, but never thought of that use.
I used it once on the mill to get a 45 angle. Otherwise it’s got a lot of use around the house levelling wall plates, pictures, clocks etc. It fits nicely in my tool bag.

Would it matter if the lathe wasn't actually level along its length? (not talking about levelling the bed)
 
The first one I got was very bad - +/- 4 degrees. The next one I tried is very close, to .1 degree... I think they need checking, as they might be hit and miss, but one you have a good one, it seems to stay that way.
 
if you carefully read the reviews on amazon for that neoteck model it has the same issues I described. I think the people who like it don't need precision and hardly notice the problems.
 
I performed a few tests on mine. It doesn’t move off zero until one edge is raised 0.008” (over 2”). I tried it at 90 and 45 degrees and got similar results. Based on that I think it is good for about +/- 0.15 degrees. It’s not as precise as a machinist level, but in many cases is good enough.
 
Mine is marketed by Beall tool company but was made in China. It was purchased at Lee Valley. From the pictures on the internet, I think they all come out of the same factory though.
 
I have a Fowler EDP # 16672 ( 54-422-450 ), likely got it from KBC. Repeatability .05*, Accuracy +/- 0.2* as advertised. It has worked well for over 10yrs. Never thought of using it for indexing, thanks.
 
Coincidentally I just did that very same setup. I had a DTI in the chuck & was attempting to clock around a round section tapered tool (an arbor) that wasn't associated with the tailstock so it had both vertical & horizontal displacement away from the spindle axis. In practice it was kind of a pain to get the meter to settle down at 90-deg positions & read upside down digits. There is something to be said for watching maximum needle deflections using dial indicators. But using the inclinometer in certain situations has its benefits.
