The Gear Cutting Of The Custom Size Pinion Is Completed .

[@markfoster6110]

All within half a gnats pajama cord !! It's not all about the size of the dog in the fight . But the size fight in the dog !! Great job young man !!

[@swanvalleymachineshop]

I will take the win on that one ! 👍

[@pingwax.]

The fantastic content from the first part of this series carried right on through to this video. I learned a lot from these videos. Thank you for taking the time to document this process!

[@swanvalleymachineshop]

Thanks . That was no straight forward job that one ! 👍

[@russelldold4827]

The great thing about experience is it helps us to steer our luck away from wild-arse guessing towards reliable outcomes. Good work, Max!

[@swanvalleymachineshop]

Thanks 👍

[@ElmerJFudd-oi9kj]

" Unorthodised" is actually a very funny word, thanks Max.😀

[@swanvalleymachineshop]

Lol , 👍

[@petergoose8164]

Always impressive work Max. Your knowledge and ability to think outside the box make this a very informative channel.

[@swanvalleymachineshop]

Thanks 👍

[@simpleman283]

Good show Max. The amount of detail you give us is why I love your channel. What you do was worth watching even before you had proper mic sound, but now it is a real pleasure. Thanks Max for all the hard work you do to show us up close, how it is done. Cheers 👍🍺

[@swanvalleymachineshop]

Thanks . Experimenting with my phone as well as the mic . 👍

[@brianmccusker3852]

Wow, new macro photography and a cool one to celebrate. Cheers Max, glad to see the progress.

[@swanvalleymachineshop]

Thanks . Just experimenting with my phone's camera for close up's . Still along way to go ! 👍

[@clydedecker765]

Now THAT was a fiddly bit... Great job Max.

[@swanvalleymachineshop]

Thanks 👍

[@BROCKWOOD64]

I bought a gear tooth vernier. Never really knew what benefit it provided until now. Thank you for that!

[@swanvalleymachineshop]

You hardly ever need them , but when you do you do ! 👍

[@paulhammond7489]

Cheers Max, enjoy the cold one, you've earned it :)

[@swanvalleymachineshop]

No worries 👍

[@MattysWorkshop]

Gday Max, that’s a brilliant outcome, I don’t think I’d ever attempt to do this that’s for sure, definitely not an easy gear to cut, hope you enjoyed ya beer or 2, cheers

[@swanvalleymachineshop]

Or 4 , was a hot day ! 👍

[@TheAyrCaveShop]

Awesome outcome Max, Really enjoyed the detail and explanation of the entire process...👍👍 You sure disserved that cold one...enjoy it ! ATB...Cheers...

[@swanvalleymachineshop]

Thanks Dean . 👍

[@RalfyCustoms]

Badass Max! G'day mate, fantastic job as always, nicely done and very well explained, hope you're all keeping well, best wishes Ralfy

[@swanvalleymachineshop]

Thanks Mate 🍺🍺🍺

[@johnlee8231]

I'd say you've earned yourself a few beers. Enjoy

[@swanvalleymachineshop]

Thanks 👍

[@opieshomeshop]

*_I figured you were a wizard._* I'm dreading learning gear cutting. My math skillz are not so great. I did take a refresher math class last year but still need to go back for trig. I have 3 gears I need to make. I have 2 of the gears and one of the gears I need to make is missing. So, I have to figure that out as well. Won't be till my summer that task gets tackled.

[@swanvalleymachineshop]

No worries 👍

[@ThePottingShedWorkshop]

Aah, the sweet sound of a chinesium gear cutter cutting on two or three teeth! That was a good result. As the flats at the tops of the teeth were worn to a point I wouldn't think the new gear will give any problems.

[@swanvalleymachineshop]

Cheers . I think all their cutters do that , a custom grind to run true on a bent arbor !👍

[@markwatters6875]

Another top video with great outcome. Thanks for all the detail and explaining you put in the videos mate. Have a good one 👍🇦🇺

[@swanvalleymachineshop]

Thanks 👍

[@Darkrif1957]

Nice work Max👍

[@swanvalleymachineshop]

Thanks 👍

[@pauldehaan3574]

Wow that was an impressive machining job. lots of cuts for 12 teeth for sure. Thanks for sharing..

[@swanvalleymachineshop]

Cheers 👍

[@tas32engineering]

Its all about sneeking up on the prime number. A little indexing trickery & wha la another maxy video.

[@swanvalleymachineshop]

It nearly snuck away from me ! 👍

[@alasdairhamilton1574]

Earned two beers 🍻🤗👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

[@swanvalleymachineshop]

Cheers 👍

[@624Dudley]

Thanks Max, that was quite a ride. I hope the heat treat doesn’t skew everything…😏

[@swanvalleymachineshop]

That's my biggest fear ! I have left a good grinding allowance . 👍

[@1crazypj]

@@swanvalleymachineshop I recently read in a 1942 manual it should be normalised before heat treating to relieve any residual stresses

[@tomsing6384]

You know, I just was looking at your shop, it is number one, look great, I am a retired electrician and it look as if you had a good commercial crew doing the work.

[@swanvalleymachineshop]

Thanks . I have done all of the work from the ground up building the shop . The only bits i could not do were the concrete & the electrical work , as that has to be done by a licenced electrician . Cheers 👍👍👍

[@somebodyelse6673]

I would have to learn So Many Things, to do what you just did by eye. I can make chips as well as the next guy, but you're doing mechanical art there, fella. Thank you for sharing, again!

[@swanvalleymachineshop]

No worries 👍

[@kentuckytrapper780]

Excellent job max, great video, keep'um coming..

[@swanvalleymachineshop]

Cheers 👍

[@bostedtap8399]

Passed your trade test on that job Max, definitely ask for top rate after that; and filming it 👌✔. Excellent job, I was stressed watching it, that's from the other side of the globe 🌎. Definitely keep the old one, and see if anyone can try to make a new one? Thanks for sharing and best regards from the UK. John.

[@swanvalleymachineshop]

Thanks . I have never seen one done before . 👍

[@TrPrecisionMachining]

very good job Max

[@swanvalleymachineshop]

Thanks 👍

[@graedonmunro1793]

enjoy your beer mate,, i was watching you using the mic at the end of the vid and realized that they are made for right handed people!! ( my brother was a leftie so i notice these things)

[@swanvalleymachineshop]

Even being a lefty , the right hand comes natural ! 👍

[@joell439]

I’d say phenomenal results 👍👍😎👍👍

[@stevecanny1583]

Real nice job Max! :)

[@swanvalleymachineshop]

Thanks 👍

[@Gjed16]

I think the term in Oz would be "bonzer". This has been a master class in matching a unique, non-standard gear profile. The finesse you exhibited in 'carving' that profile leaves me in awe. I feel like I completely understand every step you've taken and the reasons for taking those steps. You simultaneously effectuate AND educate. You have again proven your qualification for the title "Master POTMA". 👍👍🧠🏆⚙👏💯🍺🍺

[@swanvalleymachineshop]

Lol , Cheers 👍

[@melgross]

These tooth calipers cost around (metric only as far as I can tell) $55 US for Chinese versions of this. I bought one and it’s really pretty accurate. Some of the finish grinding leaves something to be desired, but I’ve found Chinese tools usually are really good where it matters, and not very good where it doesn’t. But then, a new Starrett model of the same tool costs Around $1,600 US! A slight difference.

[@swanvalleymachineshop]

I picked up that & other gear including that new condition Mitutoyo 18'' height gauge from USA a few years back when our dollar was quite close & postage was still cheap ( that did not last long though ! ) 👍

[@ianpendlebury3704]

Just subscribed. Wonderful instructional stuff; so much practical knowledge. I will be looking though your back catalogue. Thanks.

[@swanvalleymachineshop]

Cheers 👍

[@simpleman283]

I've been here for 3 years, he have a ton of good stuff.

[@warrenjones744]

I have never done any gear cutting, The need has never come up and. I do have a dividing head and gear tooth Vernier just in case..Heh Heh However I have a friend close by that has a gear shop. Next time I am over there I will ask him how he might approach it with his hobbers and shapers. (if I can remember that is!)🤣 Anyway, good show Max! The JFMT will be operational again soon, thats a good thing. Cheers

[@swanvalleymachineshop]

Thanks . 👍

[@trevorjones4463]

Well done mate 👍

[@swanvalleymachineshop]

Cheers 👍

[@stovepipe666]

turned out good max you wouldn't want any interruptions though

[@swanvalleymachineshop]

You are not kidding ! Cheers 👍

[@daveharriman2756]

Outstanding work!

[@swanvalleymachineshop]

Cheers 👍

[@Rustinox]

Great result, Max. In fact, it was easy. All you had to do was to cut away the material you didn't need :) BTW, I like the fine adjustment in your dividing head. That's a nice touch.

[@swanvalleymachineshop]

Lol , i was going to send it to you to cut in your shaper ! 👍

[@Randysshop]

Nice work Max. Now as long as something crazy happen when you heat treat the part it will be a win for sure. Cheers

[@swanvalleymachineshop]

That will be the scary part !!! 👍

[@1crazypj]

This is hell of a good tutorial, easy to follow but I don't think I would want to attempt it. I would say a major win to be around 0.0005" difference over pins, probably better than original production tolerance? That's the stuff that vast majority of hobby machinists (and even professionals) never see or understand and why gear cutting becomes so difficult and specialised 'art' on manual machines. I have read up on gear-cutting multiple time, 1930's/40's text books go into detail about standard and modified gears, put me off attempting it when my father gave me all my uncles stuff on 'everything' ( books on gear development, armourers manuals, etc) when I was 13~14. I tried my best but too many formula's and not enough diagrams. (although I did learn to use a slide rule in early 1970's before electronic calculators were around 😁) My uncle was a bomb aimer, armourer, navigator plus I don't know what else in RAF, on Lancaster's in WWII, I know he was 'really smart'. He was shot down over Holland, I never met him. I used to teach 'how to read a vernier scale' as part of 'Machine Shop' course Pierre Vernier, 179? invented it. (would have to dig out lesson plan from 2005, very few appreciated 'history lesson')

[@swanvalleymachineshop]

Thanks . Gear cutting is an art , also like a trade of it's own as there is so much involved . 👍

[@Warped65er]

Great job. Thx for the vid.

[@swanvalleymachineshop]

No worries 👍

[@m0xya]

great stuff..! brilliant explanation..

[@swanvalleymachineshop]

Thanks 👍

[@geraldestes2470]

> laugh riot max - usually for us armchair machinists, 'eyeballed in' is a lot closer to what an ordinary bloke like myself generally terms as reckless eyeballing. it must have been a helluva beer goggles day getting that pinion sized as nicely as demonstrated. nice going.

[@swanvalleymachineshop]

Thanks 👍

[@DudleyToolwright]

Nice.

[@swanvalleymachineshop]

Thanks Rob . 👍

[@davidbawden6567]

As a Machinist Max, your top-notch...

[@swanvalleymachineshop]

Pure ass !!! 👍

[@tomsing6384]

I thought baby's were the only ones who cut teeth, but max dose it all, except sinking ships. however the toe tag HBM might turn out to be a boat anchor for that sinking ship.

Close enough ! 👍

[@TedRoza]

G'day Max. Just shows you know your way around a Bridgeport 😂😊😅. Excellent video, with all the Intricate angles. Things like that would do a person's head Inn 😅😅😅. The main thing is that it fits, & works on the Rack Assembly. What diameter chuck are you using. and ...... Great video, catch you on the next one 🎉 👏 👏 👏

[@swanvalleymachineshop]

Thanks . 160mm 👍

[@rubenmolina8849]

Could you please tell me the brand of your dividing head. I'm interested in owning one.

[@swanvalleymachineshop]

It has no name tag . It is a copy of a Cincinnati wide range . The head as far as i know came as standard equipment with a Jafo Jarocin milling machine . 👍

[@willemvantsant5105]

Hi Max, hoping the rack to pinion mesh hasn't changed too much over the years, saddle and bed wear causing more backlash on the hand wheel, that's not an easy fix.

[@melgross]

I find that racks don’t wear that much. Even if you’re in approximately the same place on the lathe over time, there are going to be far more teeth of the rack engaged over time than on the small pinion. So each tooth of the pinion gets used dozens, if not hundreds of times more than a given tooth in the rack. Of course, if it’s a soft rack then all bets are off.

[@swanvalleymachineshop]

The first 1/4 is worn from the knackered gear & possibly the rapid traverse . I may replace that section yet as the sections can not be easily swapped from front to rear . 👍

[@willemvantsant5105]

Just checked my 13" lathe, the rack can just be marked with a file, would say it has been heat treated and fortunately little wear. Making a short rack insert would be a challenge on my vertical mill but I do have a home made right angle attachment but the cutter would have to clear the gearbox housing.

[@swanvalleymachineshop]

@@willemvantsant5105 I would probably do it with my Bridgeport slotting head .

[@willemvantsant5105]

Never thought of doing it that way, I do have a slotting attachment for the mill, last used for cutting an internal blind key way. Probably easier getting someone with a gear Shaper to cut the teeth.

[@trevorjones4463]

Or 2

[@swanvalleymachineshop]

More like 3 or 4 👍

[@1ginner1]

Hi Max, 0.0005", you should be ashamed of yourself, very sloppy work. lol, superb job mate. Best wishes, Mal.

[@swanvalleymachineshop]

Send it back as rejected ! 👍

[@be007]

if you listen to the cutter sound, it only cuts on a few teeth ? are the cutterteeth not on center thanks for sharing max. cheers ben.

[@swanvalleymachineshop]

Bore of cutter not true to teeth of cutter . 👍
