Review: Well made super accurate - Well made classic machinist level
Review: Amazing precision! - If you thought a good hardware store level was precise, think again. I needed this to level out the platen on my wide format printer, we’re talking about fractions of a mm tolerance that were causing the print carriage to rub. After using steel thickness gauges to level everything out, we were still getting a slight bit of blur across the travel. Bring in a $300 level I never knew I needed. First, you have to calibrate this yourself. Look up some videos and find a VERY stable table or just go straight to the concrete like I did, just make sure the floor is clean and there is no lose debris. Place some tape marks and take your time alternating directions. Once calibrated, you’ll be able to capture the slightest inaccuracies. 0.0002” per foot tolerance is no joke. We were able to plum up the platen in no time and fix the detail issue with the printer. Life saver! Would have never been able to achieve the same results using an ordinary level, not even close. It’s expensive for what it is, but everything about it is precision machined and the glass vial is insanely sensitive. The 12” version I purchased actually comes with 3 total levels. I knew it had an extra one on the front for a second axis, but it also has another for a 3rd axis located in the middle where the finger holes are. At this price and sensitivity, I wish it came with a case. It’s pretty robust and the main vial has a cover, but I’d like to give it some extra protection anyway.

## Features

- Adjustable - The vials are adjustable to a positive setting. It can be adjusted by turning the knurled knob on the side of the level, making it easy for quick leveling tasks.
- Durable Fine Finish - The base is made from cast iron and is precision-machined on the reference surface to increase durability. The vial is housed in a satin finished brass tube with a friction-fit closing cover to prevent breakage.
- Ergonomic - The base of the levels features an involute groove between the bearing flats for accurate seating on round work. This groove has a special involute design, permitting better centering and greater capacity to handle larger rounds.
- The Exceptional Tool - Machinist levels provide greater accuracy than other construction levels. These levels should be used when the variability of the reference plane is within the range of the level's sensitivity.
- The Standard for Excellence - Proudly made in the USA, Starrett combines over 140 years of American heritage and innovation with globally sourced materials to deliver exceptional quality tools and products.

## Questions & Answers

**Q: Don't you need to find a true level item to calibrate this level?**
A: It is possible to level a "level" by flipping it 180 degrees (end-for-end) and setting it up to read exactly the same number of divisions off of ideal.  Alternately, one can set up a local "true level" by shimming a surface until it reads the same with the level flipped 180 degrees...   In any case "level" can be established as derived standard.

**Q: Is this a 0005" per 10" master level?**
A: No that is a 4 inch 98 level good to .005 if an inch.

**Q: how do you calibrate this**
A: Find a pretty level surface set 98 on mark with sharpee  the edges.. on one end of level are hex nuts above and below that is your ajustment point with level on surface and marked with sharpee look at bubble now turn level 180 degree make sure to put the level back into the marked area look at bubble now a just ..

**Q: are the screw and stud supposed to be centered on the post? The one I received had the holes off center.**
A: The upper part is an unmachined casting, but I am sure that Starret makes sure that the holes are drilled centered to the prizm below.
It is not relevent that the hole is not centered in the post.
Just my two cents.
