Making a Vernier Degree Wheel for the New Hobbing Machine!

[@mudnducs]

I so enjoy your work. I’m a retired ME and never got to do precision work like this, always wanted to. Now I’m putting together my own machine shop and your insights are GREATLY appreciated!

Best of luck!

Another nice tool build. We shared this video on our homemade tool forum last week 😎

Thanks, I appreciate it!

Tom, Towards the end you talked a bit about working with model makers, it was very enjoyable! I, myself am a young (2 years out of school) mechanical engineer working in forging press repair. I’m lucky enough to have management willing to allow me to mess about on the machine tools for repairs that aren’t particularly hot. I’d love to see a video either specifically about or simply featuring commentary about how you started your career and the specific bits that lead you to your current interests and skillsets!

[@thomasstover6272]

@@college533 I really appreciate this feedback! Thank you! I will think about this and try to come up with something that works!

Tom, this was a great video and I learned a lot. When you showed your colored drawings behind the paper & plastic vernier demo sheets, I immediately remembered doing that on some really poor reproductions of fixtures used to build replacement avionics racks for a large aircraft. The drawings when printed off of aperture cards and cut & taped together were ~10-ft (~3-m) long. I re-inked many of the extremely faded lines & then colored in the drawing to show different materials to out Toolmakers. They really loved those drawings after seeing the originals that they were supposed to work from. I eventually let them use my copies while they worked on the many rack fixtures. When I was a tool & fixture designer, our Supervisor arranged with the Tool & Die Supervisor for many of us to actually work with multiple Toolmakers for a week. I loved that week and really wanted to work under the eyes of the Toolmakers for much longer. I also wished that we Design Engineers had to (sometimes) manufacture our own designs -- that would have been a real learning experience for all of us, especially the Engineers that weren't really the best that we had -- it might have made them much better, IMHO. What material would you recommend as the "tint" in the engraved lines & digits? How would you finish the engravings" Thumbs up & subscribed! Now I need to binge watch your older videos! ;) (I'm another retired ME like @mudnducs below.)

@@bobvines00 great story, Bob! You will see those colored pictures again soon. I’m going to have to experiment with the scribed lines. I have used sharpie ink, crayon, and paint followed by a god rubbing.

Gday Tom, very well explained, beautiful work as always and brilliant tool for stamping the numbers, cheers

Thanks, Matty!

Its very fascinating work you have done here. It goes a little over my head but one step closure to understanding the micrometer. Thank you

Thanks soo much for this video!!! I have been searching on how to make a vernier scale and surprisingly, couldn't find anything explaining how it works. Now I can make one for my lathe. Thanks again!!

@@dieguerrero that’s great! Let me know how it goes!

[@dieguerrero]

@thomasstover6272 It will probably be while before I get to it. Currently I'm building a 16" telescope, all from scratch except the optics. Right now I'm finishing parts of the focuser using the lathe obviously. Thanks!!!

Very interesting. Nice work sir. Gave me quite a few ideas now.

Good! Go for it!

[@billshiff2060]

What I want to do is make a decimal vernier scale to add to every tool so I can read decimal degrees as well as deg/min/sec. I get a lot of drawings where the angles are expressed as decimals.

Good Morning Tom, thank you for your videos, I learn so much watching them, and they are truly enjoyable. I always liked the frame work and set up fixtures for your gear set ups but out of curiosity, what type of steel do you use for the set up frame work ? And gears? And do you harden your gears? I am a total amateur, and was curious, and I would love to know because your work always has such a great look aesthetically.

[@thomasstover6272]

Thanks, John! I don’t use anything fancy, for the most part. The frame parts are 1018 steel, as are many of the gears. The power gears are made from O1 tool steel, but as yet unhardened. Glad you like the vids!

[@paradiselost9946]

lol, i figured this out a year or two ago, why the rotary table has the extra marks on the dial..."oh yeah, its a vernier!"

[@markfischer9216]

Good explanation of a vernier scale, thanks.

Hello thankyou for sharing. Could you tell me were i could buy those number stamps and the part that ceneterd stamp and held it? Thanks

@@freedomenergy6644 The stamps are made by Pryor, and I got mine from Amazon. Highly recommended..mine are the 2mm size. The guide is a shop-built fixture. A you-tube search will turn up various ways to do that. Thanks for watching!

12 - 60' = 11 ????

[@thomasstover6272]

@@rljzathras New math. …actually, it’s DMS. Degrees-Minutes-Seconds. 12 degrees minus 60 minutes = 11 degrees

[@rljzathras]

@@thomasstover6272 Yes, that's what I was saying. The creation of a degrees symbol failed me, but my understanding is minutes symbol is a ' and seconds are a ", so 60' means 60 minutes = 1 degree. 🙂

[@thomasstover6272]

@@rljzathras The last tick mark on the vernier scale is superfluous, since that mark coincides with the next full degree mark. I think we’re agreeing…did I say something different in the vid? Sometimes my mouth leads its own life…🙂

[@camillosteuss]

@@thomasstover6272 nah, you just said ``12`` at one moment, so it left me wondering if you forgot to subtract the 60min or 1 full degree... I think he wasn`t even wondering at the math, but asking if you followed up on the math in practice, just like me... Checked - As you were cutting, you said ``the last mark is 12 degrees`` without adding the subtraction at 20 mins 50 secs... It`s not what you said, but what you didn`t say that caused the ruckus... Best regards!

[@rljzathras]

@@thomasstover6272 Yeah, you were saying 6-30', 8-40', 10-50', then next mark was announced as 12. Then you said I've lost my way, which obviously makes sense if you did dial in 12. Clearly the end result is correct @ 11 as it looks OK :-)

[@EdwardKilner]

Gave up around the 20 minute mark. Could not see what you were doing, except a lot of your head.

[@thomasstover6272]

You’re not wrong about that. Down to one camera at the moment. Kind of surprised you made it that far, really…😊

[@camillosteuss]

The thing is, all that he was doing was contained in that head, so you were technically seeing everything... Plus, you are likely in the metalwork field, quite likely machine work oriented, so you know what he was doing... There are remarkable machinist videos on youtube that are almost movie grade, and then there are dudes who simply do this sort of thing because they want to share the content hidden in their heads, and most often it`s guys who don`t bother with finesse outside the realms of precision finishing of clearances and tolerances between componentry bearing surfaces... I myself enjoy a good rant or a decent talk on pleasant subjects from machinists, as we who dabble in old iron tend to appreciate old values and proper virtues, so you know that the talk is going to induce some relaxation and pleasure, plus it is bound to recall some memories from your own experiences, compounding the feeling... Don Dyar is a good example of a ranty old machinist/millwright whom i can listen for hours as i scrub away the crusty oil from machines and tend to them, plus he has some ridiculous machinery, so that offers the pleasure of seeing them in action... Stefan Gtsw is also a pleasure to watch at work and hear his thoughts, just like Robin Renz... And if you want cinematic, you have This Old Tony(sleepy tony in the last few years) and Inheritance Machining along with Breaking Taps and a few other such channels... Best regards! Steuss
