One of the other commenters hit the nail on the head when he said this reminded him of a vernier scale. I think of it as a physical (as opposed to visual) vernier. It's also a little reminiscent of the indexing method used by the spindexer devices. Thank you for sharing.
I haven't ever used this for linear applications of any sort, but the rotational application and the affordability of the parts made possible on hobby-level 3D printers have allowed me to achieve *VERY* high gear ratio reductions in very small planetary gear trains by differing the tooth count between stages by one. This approach would be very costly if custom gears could not be 3D printed cheaply. Oh my gosh I'm so glad I found your channel!
Thank you for the information! I have a perfect aplication for this. I'm a Toolmaker in the plastics industry and our shop has been in the need for an ejection pin cutter that will consistently cut pins +.005" -.000". I was planning on using a micrometer thimble for a stop, and have the stop index into a groove in 1" increments. I think by using this method, the fixture will be more robust and not have to worry about the thimble being out of adjustment.
I drill very small holes for microfluidic experiments. Sometimes I need to very precisely add a hole to an existing manifold. I’ve been using a toolmakers microscope / sensitive drill combo I rigged up, but without a precise x/y table it’s cumbersome to get to the final position after picking up a reference hole. I’ve been scheming on how to get there without spending a fortune and this gives me ideas. Thanks!
Your sigh of frustration over a few micron out of a 3d print made me smile for some reason. Especially when you've got compounding deviation from 3 separate prints. I love this idea! Thanks for these videos.
Adam, your sound quality is remarkably better. Thank you for spending time to improve that aspect of your video. As always, great information and clearly communicated.
Very nice concept - it's reminiscent of a right-hand thread/left-hand thread differential screw setup. You channel was recommended by Stefan Gotteswinter.
You can make differential wedges that can theoretically adjust infinitely fine with a fairly coarse-threaded fine adjust screw. If the wedges are say 6" long and 1 is tapered .0001 in 6" and the other is tapered .00015 in 6", I can't even calculate how fine the adjustment would be for a 40 pitch thread.
Thank you for this - and your previous - excellent videos. So far, you've covered several interesting topics that I, as a hobby machinist, have never heard of before. And yes, the sound quality of this one is much improved over some of your earlier presentations. I've heard several RUclips machinists mention that they've spent way more on audio gear than on cameras & video equipment. They didn't go into much detail, but I suspect that various highly directional mics (noise cancelling, "shotgun", etc.) are a big part of it. There are also relatively inexpensive in-ear mics that pick up your voice very clearly from inside your ear (basically an inward-pointed mic) while rejecting nearly all external sound sources; essentially an earbud that can also function as a microplone. These are often used by motorcyclists. ...One other possibility just occurred to me. I've never had any reason to try this, but you might even be able to plug a set of ordinary earbuds into the right kind of microphone jack and get the same tesult? Or that might not work; it may take a more sensitive transducer to act as a good microphone, or the impedence might not be a close enough match for any standard type of mic? Anyway, thank you again. And if you continue to produce similarly great videos, I can see your channel becoming one of the "big" machining channels in the coming months! Douglas Hank
This is awesome! Great to see your subs screaming through the thousands already, you have some excellent tips. Great point about printing in the gears at the same time on the same axis, I'd have never thought of that
I really like your thoughts on how to reach high precision with relatively cheap 3d printed parts. I look forward to your next videos! Thx for sharing!
This could be very useful in a DIY surface grinder setup, Set up an adjustable RDM bench grinder. Then you can make a sled that adjusts using this mechanism in the middle with legs that can lock to support it. Perfect for small precise movements on the cheap. I'd bet you could make a decent surface grinder for under 200 dollars with these.
Hey Adam, fantastic videos! One thing that might make the linear indexer more repeatable is a consistent tension on the preloader. Perhaps a spring retraction system or a consistent torque value on the preloader screw would be the best ways to fix that.
Awesome, thank you for doing these videos. Keep them coming. Would love to see your thought process start to finish on how to tackle an interesting part. 👋💪👍🤘
Way better sound!, I just learned about your channel, I am not a machinist but love learning about it and have learned about your videos a lot, thanks for sharing! :D
fascinating idea. I can see how replacing those plastic blocks with threaded bars milled flatish to form a "rack" could work in the same way too and you could get very good control over the pitch and form and choice of material by threading on the lathe.
The saw stop idea is great. I'm going to implement this into my radial arm saw and will be able to cut off my fingers repeatedly to a few tenths. I know the orthopaedic surgeon will appreciate. But really this is super cool and makes me think of Moore and the stuff those guys were up to. Thank you for sharing this.
Thank you for the tutorial. I think there would be various optical alignment application where high stiffness (high resonant frequency) that would benefit from this. I will try to sneak this into my work one day!
Gday Adam, I found this very interesting really, amazing how accurate a 3d print can be, im looking at getting my first 3d printer atm, I have a lot of learning to do mate, thanks very much for sharing, cheers
I did a lot of AMP connector Mold's. The core pins had a lot of minute and second angles we would dress on our grinding wheels. Most of the tolerance were + .0000 - .0002. Inch.
This principle is really awesome, something to add to the mental library. That said, have you ever looked at the teeth of that rotary setup? I'm trying to figure out what the divisions must be to end up where you want to. If you make the divisions for the first disk 1°01'00" you'd end up with 354 teeth, but for the second disk with 1°00'01" increments you'd need an insane amount of tiny teeth, like 3599 or 3601 teeth. And even then you'd have tiny deviations.
There are three plates. The first degrees plate has 360 teeth (1 degree ) the next is the minutes plates and had 359 full teeth at 1 degree and one minute per tooth , the partial tooth is remove . Same deal for the third plate at one degree one second
I don't quite understand the indexer. Maybe I'm missing something, but you can't have 1°1' tooth pitch around a circle. That won't divide in 360°. How do they solve that?
Amazing content! I am having a hard time getting my head wrapped around the Newbould indexer. Having teeth mesh every 1° 1' seems like it would not result in closure around 360° (with a whole number of teeth). What am I missing?
@@adamthemachinist Ah, had a feeling. Thanks, Adam! I've been considering building a time machine, just to go into the future and watch all the videos you make. They're truly inspirational.
I run a Pruasa, which is fine for my needs . Seems the best value for desktop market is the bambu these days. Haven’t ran one but many people I trust seem to praise them
No there is no torque here. He is suggesting herringbone profile so the parts will be locked not just up and down but also side to side if you need that.
Really interesting video Adam, thanks for sharing. I'm really impressed that you got such accuracy from a 3D print, can I ask, are you using an FDM printer or SLA?
This is so cool! I first learned about elastic averaging from Dan Gelbart ruclips.net/video/HWPYoE1SNnA/видео.html but I didn't quite get it. Your examples are very helpful.
I like the idea of using it as a precise adjustable and very safe hardstop. Thanks for the idea!

This feels like a vernier caliper with teeth
I was thinking the exact thing
Good stuff Adam!

@sourand jaded In some cases you can set up your compound to such an acute angle that any infeed would be in the micron range.
You are such a good exspliner showing with your fingers and hands how the teeth flow together.
Thankyou for sharing.
Your sigh of frustration over a few micron out of a 3d print made me smile for some reason. Especially when you've got compounding deviation from 3 separate prints. I love this idea! Thanks for these videos.
I have no current use for this concept but like having it as an option now. Thank you! Oh- The same orientation on the print bed is a good tip.

You just explained the newbould indexer to me. Something that I had heard about vaguely and failed to understand for 10 years. Thank you!
This is so awesome!!! Thank you for making these. Loved every one and learned even more.
Greetings from Germany.
I always get impressed on how you thinking process "out of the box" takes the 3d printing technology to amazing levels of practical precision...
You provide content I have never seen anywhere else before. It is fascinating! Thank you so much!
Thank you for a simple explanation of a complex topic. Not easy, and greatly appreciated!
Excellent! Your measuring and gaging to machine tool cost are the highest ratio I have ever seen. As a retired QC guy, I love it!
Well thank you. When I start the shop I decided that was one area I didn’t want to skimp

To be honest, it's kinda amazing that you can achieve accuracies below 0.01 with basic FDM 3D-printed parts.

Wonderful demonstration. I really appreciate the knowledge share.
Fascinating, really interesting. Great vid. I'm sure there are some more applications of this.
Its an interesting idea Adam! Thanks for sharing!
This gave me an amazing idea for a design I'm working on currently. I'll test it out and if it works I'll share it with you. Thanks a lot
This is brilliant!
Ah, I see! It's like a vernier scale, but kinematic instead of optical. Very clever!
Great sound! Interesting tooling.
If you transfer the idea of the linear gear to crown gears you'll be able to 3d print an rotary indexer with exchange plates.
fascinating idea. I can see how replacing those plastic blocks with threaded bars milled flatish to form a "rack" could work in the same way too and you could get very good control over the pitch and form and choice of material by threading on the lathe.
Thanks for the interesting video, I wasn't aware of this clever system.
Food for thought. Thanks.
I find this a little similar to the method used to make up a gage block stack. Or using a vernier on a micrometer or caliper.
I like the idea for a tablesaw fence. Much easier than trying to keep it square, or doing some kind of lead screw thing with gearz.
The saw stop idea is great. I'm going to implement this into my radial arm saw and will be able to cut off my fingers repeatedly to a few tenths. I know the orthopaedic surgeon will appreciate.
But really this is super cool and makes me think of Moore and the stuff those guys were up to. Thank you for sharing this.

If you quit toolmaking, you could take up acting. You're a natural!
Thanks for sharing! 3D printers allow for fun exploration of concepts. Keep these coming, please!

If you google”practical machinist mother of all invention” the inventor details the development
@@adamthemachinist thanks for bringing this up, it's extremely interesting
Clip a microphone on your collar - it will make your audio MUCH better.
Wouldn't constant engagement and disengagement lap them in and make them more precise in time ?
genius
I don't quite understand the indexer.
Maybe I'm missing something, but you can't have 1°1' tooth pitch around a circle. That won't divide in 360°. How do they solve that?
@@niemanddings9517 it’s not a total circle , several teeth are removed.
Amazing content! I am having a hard time getting my head wrapped around the Newbould indexer. Having teeth mesh every 1° 1' seems like it would not result in closure around 360° (with a whole number of teeth). What am I missing?
you are correct in that its a non integer of a 360 degrees. to over come that , there is a section of teeth missing which allows for meshing
@@adamthemachinist Ah, had a feeling. Thanks, Adam! I've been considering building a time machine, just to go into the future and watch all the videos you make. They're truly inspirational.
Do you know if Heidenhain still sells that measurement device?
They do, it’s their metro gage
Hi Adam,
i wonder which 3D printer you have. Print quality looks amazing ! (I'm currently looking myself for a printer to buy)
