James, while the error may only be slight, spacing your 40 arcs that way isnt spacing them at 0.1 inch, because the point is offset from the centre line, the measurement will be the tangent length of the point from the centre, so your arc spacing will be something like 0.101" (no I havent worked out exactly the measurement)

Glass and metal tech here, you could also try a frosted/obscure or transparent film. Some good 3m fils (and heaps of others) will give a more even and optically better viewport, also easy to replace/consistent and will protect the marks from oxidisation. You can also acid etch the glass but this process leaves it extremely susceptible to oils as they are almost impossible to remove. We normally get our acid etched glass in already finish 3 or 6mm sheets and toughen or heat treat after cutting to alleviate the issue. Its diy if your have the time too if you can’t get it cut to size. If you wanted to bring these to market my recommendation would be: 2 or 3mm Low Iron clear glass (no need for scientific grade), un-toughened/untreated (the film will add safety should it break) and then the best transparent film you can find. Honestly, with all that said, I can’t believe it worked so well with the frost spray- a perfectly serviceable result for sure!! Great job!

We use transparent overlays at work. You print them out like we used to do in school back in the day and the comparators have spring fingers that hold them to blank glass. They're nice because you can CAD whatever feature with tolerance lines and such then just line it up real quick and have a look. You align the transparency with the motion of the axis by just including a couple reference marks in the print, then aligning them by sliding the vise or a part across while rotating the glass to straight. We also have some with the more general charts like on that glass.

For future projects where you want frosted glass, take a look into frosted glass vinyl film. Has an adhesive side that you apply directly to clean glass and gives a superbly regular frosted look and would probably be more durable than the paint. Application of it can be finicky. Obviously very very clean glass and work space, I use very dilute soapy water and float the film on that them squeegee out the liquid. Best results after several days of drying out.

You don't want a even back lighting. You want a point source light. The idea is the light rays emanate from a single point, pass the edges of the part, which is reasonably close to the source, and then continue in a straight line until they hit the glass, much farther away. The magnification comes from the ratio of the distance from the light to the object and the light to the frosted glass.

An optical comparator is basically an overhead projector with a built-in calibrated screen. Even the best projection lamps that were designed with a relatively small filament area aren't a true point source, so a lens group and possibly a spherical reflector are required to produce a true point source. If you just used the lamp without the lens you would end up with an image with fuzzy edges, which would be pretty much useless to see fine details.

You used to be able to buy sheets of frosted glass, which once was cone with acid etching. It may still be done that way if anyone still makes frosted glass at a glass factory. If it is still obtainable, it would be interesting to see how the Cermark and laser works on burning the lines into the frosted surface. In the old days it was not unusual to make marks on the front of the glass with grease pencil or even paint. Often there would be an outline of a tool to be checked, marked on the glass to make it easy for you to get the tool set in the holder in the right orientation and position it correctly.

We tried it. The results were not usable.

Color me Awesomely Amazed. This video maybe one of your finest... Your attention to detail as always is top notch. Your presentation is as close to perfect as I have encountered. I love that you went to the trouble to product 3 different types of the same project. If I was 30 years younger I would be looking for some broken glass or faded glass comparators to buy and upgrade, but sadly my eyes are too old for tiny work ( Looks tiny to me ). Bless you for all the wonderful videos you share with us. Thank you again for another amazing project. As always your presentation is spot on and beautifully edited. Thanks for sharing .... Stay safe and well ...

Thanks! All the time is spent in the design, so trying different combinations is cheap.

@@carlhitchon1009 I had Cataract surgery in 2005. Shortly after I was injured in an accident and my right eye was severely injured. 5 surgeries later I have some vision ( truly blessed to not have lost the eye ) in my injured eye. My problem is I can't find any of the Gold in the Golden Years... Damn I have sure looked hard for that Gold ... Thanks for your comment.

If it hasn't been said, when I di this kind of work I burn the cardboard circle out and remove it that was it sit exactly on center and prevents any movement as it is cradled in there. For small part I use flat balsa wood instead of card.

James, I say! Rather nice work! By the way, I've been under an impression that they use media blasting for getting frosted glass finish.

I really enjoyed this video. I've been wondering how I could mark up some frosted glass for a project of mine. Well done!
