Need digital level to measure 0.250ö surface

[tomwalz]

Looking for digital level or protractor to measure 0.250” (one quarter inch surface). I can find plenty of them but nothing small enough.

Application is measuring radial and tangential angles on the carbide tips of carbide tipped saw blades.

Anyone know a source?

Thanks,
Tom

Do you mean the protractor body needs to be small? How small?

I assume you have look at the digital models at Mitutoyo- too big?

An optical comparitor seems to be more likely for this kind of application.

I agree, search for an optical comparator.

Well, I'd jump on board and make it three votes for an optical comparator...but Tom probably knows about those...

Tom, are you looking for something capable of being used in the field?

Tom,

Just jumped away to do a little searching, but came up with nada. The device I envision is essentially a small, portable toolmaker's or machinists' scope (the kind with an internal reticle for measuring angles), attached on a slide on a rigid beam; the other end of the beam should have some means of finding the center of various shaft/hole sizes. Izzat sorta what you are looking for?

After your post, I wonder why some form of (custom?) gauge block could not be used? Place the block on your surface a standard digital level on the block.

Thank you for your suggestions.

I hadn’t thought of an optical comparator because I think of them as big machines. I saw the pocket units but the problem is having a base for comparison.

I did a quick page which Emily, the webmistress, has put at

Thank you,

Oh, side angle, not rake/tooth angle...

.001 in 3/8" - that's only 0.15 degrees, with an error of about +/- 0.15 degrees? Not sure that a protractor or clinometer (inclinometer?) will get that good, that small.

 

[tomwalz]

Side angkle, top angle and rake angle. Also hook angle if we could get it.

A big honking magnet to clamp against the saw disk?

Here are three approaches that might be able to solve your problem. I have used the Titan Type Scope many times. I also used a similar setup as the PC Gears setup. Then there is the add on's to an existing microscope by Home Training Tools.
I'm also looking for a company that we used to measure some weird stuff. I just haven't put a name on anything at this time.

I think this is closer to what you want, but still too large by a factor >5:
