This might be the best explanation of gear cutting that I happened to stumble upon after seeing 40 others that left me lacking.

Congratulations on preserving so many Atlas/ Craftsman machine tools in as new condition so that a wider audience can see how capable and well designed they are. The Sears catalog come to life. Thank you.

Wow. I am lost. Because I lost nearly one week looking for such video. I finally found you. Thanks for video

Very nice, concise explanation and demonstration. Very good speaking ability. Easy to listen to and follow, unlike many KZfaq presenters. Thank you

Got an old atlas and finally getting around to restoring it. This old school machinery requires a real education, unfortunately since the 90's I feel our education system has failed America. Thank you for this content! keep up the good work.

The clearest and simplest explanation I've ever seen, of a relatively complicated subject. Beautifully photographed and without the usual distracting waffle. Thank you for an inspiring video.

Very good video and lesson. I've collected several Atlas Machine tools over the past 40 years but never had the time and room to play with them. Now, I hope to clear an area in my basement and restore 3 them. The drill press was still in it's original crate when I bought that one. Good Luck, Rick

That little mill is so sweet , Thanks for that . Cheers Ade.

50 plus years since I last cut a gear and the little grey cells had gone a bit rusty so thanks for a reminder on the formula working out what cutter is required. A real good video

I watched the whole thing, it was very good. Thanks for posting. Loved seeing that little mill in action.

So pleased to have found this video. I purchased an Atlas several years ago and am only now getting educated on its use. Excellent information and tips.

Thank you for sharing this. I'm ready to start cutting gears on my Atlas.

Thanks for the simple explanation of what you are doing. I want one of these mills. We appreciate you Sir.

Wonderful little mill.

I really enjoyed your video. Beautiful machines.

Excellent program.

Your explanation as simple and pristine as your machine.

Lots of really god detail. Thanks

liked and subscribed: Wo! I like to watch stuff like that, it's the realization of dreaming to know-and-see without the need to own 1000s of dollaaars worth of equipment. WELL DONE, wipes out most of the other videos that are so coarse and time-wasting. Please bear with me, I could be confused, but I bring up what I think a structure of understanding... Now, I am young fire-spittin'-noob... never have had a chance to even come near such equipment, but I am a bookworm, thus I can relate to everything shown here, technically wise... a bloom of geometry! Guaranteed, my automatic without brakes brain whirlin' sends me into all sorts of conjectures and questions. I am learning all of this without even a sheet of scientific graph paper, pencil, compass(not the boussole type), protractor, etc... I do keep a caliper within reach to get a more precise feel of my mind's estimate as to what 1 in.(or any fractional part) actually is, but that's it. I want my mind to be the complete dictionary, so I can go to the job light, no tool bag encumbrance. GIVEN: just about all that is involved revolves around PI(or TAU if one prefers to use the RADius as the base), irrational it is, thus get used to approximate measurements dealing with the decimal imperial system. In what may be referred to as direct distances the fractional imperial system follows a binary sequence: ..., 1/64, 1/32, 1/16, 1/8, 1/4, 1/2, 3/4, 1, ... which translates into ..., .015625, .03125, .0625, .125, .250, .500, .750, 1, ... also a binary sequence. ...no, I do not know those by heart, I just manipulate the numbers in my head and come up with it as needed... now, 1/2(.5) and 1/4(.25) and other easy ones, no computing needed. So, this appears easy, until PI/TAU says, not so fast buddy, there are a multitude of numbers between these easy direct numbers that only PI/TAU can provide... so, get your formulas and calculator out! We can see that the higher the tolerance(smaller distance), the decimal places increase... For example the 1/64 takes us to the 100 thousandths, that's a digit away from the millionth! Therefore when a particular precision is rounded(as was noted on the cutter tool, it would be nice to know the rest of the digits to see how far from the 'direct' rounded number the actual computation is. why? ...well if the number of teeth gets high, there is an accumulating(or diminishing?) effect, obviously, is there not? Surely, the simple answer is that at the counts currently used, this is not a concern. ...and that is ok, but it does not address the above conjectures. QUESTION: at what decimal place does a machinist disregards the discrepancy, ON AVERAGE? ...and I can feel this is not a fit all answer, there is a stair case effect, thus the answer needs to be comprehensive, not just a one figure. No, no tables, no thick book to carry around, just a count of digits to the left or right estimate. One clue would be the smallest tolerance used in fabrication of precise instruments... no, not at the atomic clock level... lol! I am thinking 'the thousandth' is the hover around precision.? CONCERN: if one goes around a circle with a set-dividing-measurement(a stick/chord), would not the last segment that closes the job, be OFF as compared to all other previously processed steps? (Now I understand that tolerances are needed so things have elbow room to get along(and that is a good thing), and if the precision is high enough, one small variation in one spot maybe acceptable, but how is that loss/gain [ evenly divided amongst all segments ] ? [ reparti, in one word, French ], or is it?, do we get a railroad rail clonk in the mix? RELATED: I always wonder(and must make a point to verify this) how the measurement dial lines are laid out? At one point, you did say they were hard to see... thus, when adjusting the fine spiky pointer to a particular measurement, where is the pointer visually adjusted: to the center of the line, the left, the right ? (What about the perpendicular perspective of the eye, and the precision as to where the center or the edge of the line are?) Surely, to pick one for the whole job adds to consistency, but which is the correct way? I am assuming safe center!? ...or the final tooth gap might end up too tight or too loose!? OTHER OPTION: I see this as Ole School, not a fast production option, and a massively heavy and costly device. Is this style tool being replaced, or do they still do things, the higher technology does not yet provide? - ...will not a CNC with a 4th axis produce a level of comparative precision ? - I wonder if a CNC would not get this done at the speed of light(comparatively) with a lot less chances for one killer mistake !? - ...and once setup in the CAD, an easy repeat, not need for all these steps and adjustments each time a piece is in need of making. - not even a need for a CAD for standard pieces, just get the G-code file.

Fantastic video. Thank you!

Good instructional video! Just the right pace. Not too in-depth and details as to get boring, but yet still very informative. Love the little Atlas milll, loved to have one.

Great Tutorial - Thank You! I am in possession of an MF, and am looking to put it to good use. Haven't run a lathe since high school, and loved it then.

This is a wonderful video. Please do more Atlas mill videos!

absolutely love your 'beginners' video, and that you show us how the arbour goes into the mill, and assemble the whole thing, cutter included in FRONT of us, not 'here is one I prepared earlier' like most others do, and to do one or two cuts full speed, NOT lapsed to show us the true speed of things, then go timelapse, for time, but great video; one other suggestion, how about putting marks on the indexing gear teeth on which is the 'cut' so you don't have to think too much during cutting.

Pretty cool seeing one of these machines complete. I had one of these but it was missing 50% of the components. I gave up looking for the parts and let it go to a new home. Yours looks museum quality. Thanks for the video!

so well explained!!!!

Beautiful bit of kit. Work of art. Too good to be working with.

That was fantastic!!! I’m dealing on my own lathe and soon I will be spending my life buying tooling. Lol Then I want to find an Atlas Mill like yours so I have a set. Thank you again.

I'm surprised you don't have more subscribers. You do a very nice and helpful tutorial. I have the same mill with the 1 inch arbor but don't have all the attachments. I see now that I need to start shopping.

Wow! I love working on a machine, i'ved learned a lot from this clip, thank you very much....

Your milling machine is very good

I bought an Atlas mill and shaper at an auction in 88" ,Both get used and enjoyed completely. Gave 250 for the pair.Great video.

Simple and clear Many thanks sir

Thanks for the video and great in-depth explanation.I’m slightly new to machining I’ve done some stuff simple things and some auto cylinder heads. I just picked up an old craftsman mill same as the Atlas needs a motor. I’ve never set up to cut splines or teeth so this video was great! Thanks again. Now to find tooling and cutters

Great procedure very well annotated

I’m enjoying your videos, just a note for others who may not know... Clausing is a great company to deal with, often times they will send you part drawings if you email and ask them for them, just be sure to give them the model and clausing specific part number (not just the name) it makes it super easy to reproduce parts that way.

Great video, one of the best on the web by far on cutting gears. I have an atlas shaper and was looking for this mill but the prices have gone through the roof. I just (yesterday) got a brown & sharp #2 horizontal mill in great shape with a ton of tooling and a vertical head for $700 bucks. The atlas mill only(all I could find) were $1600 plus! Down side Is the B&S is big and weighs in at 5200 lbs, but fortunately I have the space. Thanks again 😜🧑🏻‍🦽

great video.

this is real cool stuff thanks man

I am not a Machinist,but i enjoyed the video, always like to know how stuff is made ! Thanks !

Wonderful video thank you

Nicely done. Another good site is Joe Pie's where he shows how to simplify the process of using wires.

I like the index you use to do this. Nice work

Great job..

I have one of these wonderful Atlas Horizontal Milling Machines.This video was absolutely amazing and would like to know if you have any other videos about your Atlas Horizontal Milling Machine?

one tip, before you remove the dog, mark the slot in the driver with whiteout, sharpie, chalk, etc. so you don't phase the part by 180 degrees!, meaning you are not on the same place on the head stock spindle,for runout, etc.

I just picked up a Sheldon horizontal mill really good condition and got it for 300 dollars with 12 cutters and even end mill arbor , great vedio learned alot was going to get a indexing jig but I think I'll try to find the gear jig you have..

Sim mestre uma máquina que dá até prazer de trabalhar com ela uma bela apresentação 🙏

I was looking up hobbing videos, and your came up. Thought you had some sort of manual synchronizer setup. Sadly that wasn't the case, but still a great well explained video on gear cutting and some older equipment. Was a great watch :)

I appreciate your explanation of the setup of your mill. I can't seem to find a lot of info on using small horizontal mills which is a pity in my opinion. I own a small horizontal mill (not atlas, haven't seen one over here in the Netherlands) but haven't used it much because I don't know much about using them yet. Thanks for your instructional video! Peter

Great video, thanks for sharing! subscribing..

Wow cool I always wondered if Atlas made a milling machine.

nice work

Glad to see you using a fountain pen....

Cool, thanks

This is such a great video. Very informative and easy to watch... thank you very much sir, for taking the time to make our work a lot easier. One question... would it have been easier to make the gear and shaft as one piece ? Thanks again. BTW... I've been quoted £700 to make a spur gear from nylon from a local company here in Northern Ireland. After watching this video, you can only guess what my reply to them will be lol

Hi thanks for an informative and thorough video. I have purchased an Atlas Milling machine. Unfortunately no tools where with it . I was wanting to know where you can get the slot cutters Regards Peter

Hmm so correct me if am wrong use a gear to make a gear...query if can make a blank same width and thickness as old gear and enough of old gear still exists the teeth could I not use that to index it on thereby duplicating it

Hi, I just happened across your video while doing a search for horizontal bench mills. Thanks for the video! Very concise, very relaxing to view. Do you happen to know if little milks like this are still made and where to source them?

Thanks for this video! I have this index attachment for my atlas mill and looking forward to trying it. But where does the mandrel for holding your gear come from? Do you have to make it to hold your gear blank?

I had one of those mills for a little while but it was literally just the machine so I sold it on to someone that wanted to gather all the accessories. Really nice demo. How long did just the gear cutting take?

Those charts you reference in the book were created before calculators... 🤯

Ive been working on restoring my Atlas and recently discovered that I have the head stock and tailstock accesories! However I am missing the set of 9 gears as well as the dog drive. What would you suggest for obtaining the missing components?

nice video of atlas mill. what size is that mill? MFC?

Yeah,Placing those timing centers makes MFC ideal for gear cuttings..Compare Shaper/Shaver it like old vs new...This is number one main reason why Shavers been replaced with milling machines,multi bladed tools does make difference in cutting numerous minutes to several hours compare..

I had a chance to buy this exact mills for $1000 and it was in beautiful beautiful beautiful shape and I passed it by it also came with a vertical attachments I've never seen sounds maybe it was a slightly larger one but I know it was smaller listen. i am kicking myself for not buying it

Where to buy this book?

...if you measure the worn gear over wires...and then use that dimension for the new gear...aren't you losing some material off both sides of the new gear teeth?...

Really well demonstrated. But........"a poor mans indexer". Yes they would have been that when Atlas was originally selling those simple indexer's. The asking prices for them today such as on Ebay are insane for what they are. $600 - $800 or more from what I've been seeing. That's 1/2 - 3/4's of what I paid for a fairly large 10" swing Vertex universal dividing head that I think was directly copied from the B & S universal head. Unfortunately because of it's size and weight it can only be used on my vertical mill and not my little Atlas. My Atlas is an MFB model so it wasn't set up to use that highly desirable and now expensive if you can even find one vertical support bar and the other 3 parts needed to use it. Your extremely lucky to have those additional accessories for your Alas. I'm assuming yours is a MFC model? Your mill was either in almost unused condition when you bought it or you've done extensive surface grinding to put it back to how it left the factory. I'm more than envious of it's condition.

What about cooling ?

Hallo du? Bitte komm zur Sache, den deine Erklärungen sind langweilig, wie es funktioniert sieht man auch wenn du neben deinen Erzählungen ( berichten) die Maschine fertig zusammenbaust? Dann einschaltet und zu fräsen beginnst? Bitte Rede nicht so viel, der Erfolg zählt? Oder bist du ein Lehrer, der seine Schülern eine Maschine erklärt?? LG.Herbst Johann aus Österreich

Talking too much,uff, should concentrate on work
