My dad started his career as an apprentice machinist. I appreciate the opportunity to get a clue as to what he did before the war. He retired as Director of Manufacturing Engineering at Lithonia Lighting, so the Georgia connection is icing on the cake. Thanks for tripling your work load to make these videos.

Not only do I like your videos every time, I frequently share them in homeschool groups to get kids interested.

I wonder if the key was supposed to be the "weak" part, someone adding the cut-off drill bits later took that away, so instead of the key shearing, the drill bits allowed the gear teeth to be sheared away instead.

Thank You Keith for detailed account of keeping “old iron” running

Thank You Keith for detailed account of keeping “old iron” running 👍❤️

Thing of beauty. That's going to last far longer that trying to piece the old part together. It's just so satisfying too. For sure peace of mind knowing that piece is new and precision made by Mr. Rucker. As always, lovin these projects, large to small, and inbetween.

46+ years in machining and first time seeing a co-axial indicator. Good grief why so late to the game. That is slick !!!

Keith that is a beautiful job you've done making the gear. Those coaxial indicators are great to work with for bore location. It basically turns your milling machine into a precision boring machine.

That was really fun to watch, Keith. It's fun to speculate why the biggest gear sheared rather than the smaller, and whether that was designed to be that way. All I can add is to speculate that the smaller gear, having a bevel geometry, takes more setup time to grind. Hence it is the more valuable part.

I used to work for Cincinnati Gilbert for a couple of years, my wifes uncle worked there also as a foreman, I really appreciate your and all the other's creaters content of your video's.

The finished part is very pretty really. If it were stainless you could use it as a machinists hood ornament .

Really nice job Keith. Your customer should be really happy with that.

Keith, your knowledge and skill along with your patience and instruction are remarkable. My greatest wish is to see young assistants who aspire to becoming machinists standing along with you. What a fabulous opportunity for learning a critical trade that will never go away. 🇺🇸⚓️ St Marys, GA

THAT, is a satisfying thing of beauty.

That,s a thumbs from me I appreciate the time you put into the videos thank you Keith

Fantastic work, as always, and very well explained

Awesome!! Scratch this one off the list! I hope we can see some video of this steam engine somewhere down the line.

I've been looking forward to seeing this part!

Good job! Best regards from Dresden! 👍👏❤🛠😎

Thanks Keith. Great content as usual .

Great job! Enjoyed each and every step.

fantastic keith love to see you make gears!

Really nice work Keith. Thanks for sharing.

Awesome job! I learn something every time I watch.

Well done as usual.

Enjoyed watching this. Perhaps cutting a helical gear in another vid. Thanks very much.

Beautiful work!

Nice work Keith. Excellent job. Thanks for sharing. 👍

Great work, thoroughly enjoyed this.

Happy Friday 😊

Another great video. Thank You!!

Thanks for another great job and video.

Nice job!

thank you I really appreciate what you do

Most impressive work. Thank you, Sir

Thank you for sharing this

Very interesting, well done.

Beautiful work, thanks for sharing. :o)

Thank you for sharing👍

Brilliant. Thanks.

Thank you

Great video thanks for sharing

Nice job on the gear!!

I love to watch your work as an apprenticed engineering designer so I ask the question why it appears that the dowels are proud after being pressed home.

Good morning. Very nice project.

I would like to say how healthy you look with your weight loss. Thanks for your interesting videos.

Thanks for sharing 👍

You might consider Loctite 609 or 620 for this application. These are retaining compounds as opposed to thread lockers.

Nice job

I worked in a teaching shop and we lost a lot of those center indicators to novice users trying them under power. You can get the coaxial indicator pretty close without running the spindle, with less chance of disaster. Line the probe up visually at "BDC" (close to you), run the X-axis back & forth 'til you get a maximum reading. You'll be on-center-ish in the X direction; set the dial at zero. put the spindle in neutral and turn it 180 so the probe is at "TDC" (far side) and see what's on the dial. Move your Y-axis half that difference. If the Y is close, you can put it in LOW gear and run the spindle under power to fine tune.

As a young child i enjoyed watching "Mr. Rodgers" of the famous "Mr. Rodgers Neighborhood",,,,,,,,, it has just hit me that Keith is the embodiment of that show only in Metal! LMAO!!!

*- Keith, at **18:49** I am sure the pin is below the bottom of the gear's cut, but it sure does not look like it is on the video.*

I’d say those gear teeth are lined up dead nuts. 😊

I saw a video of some people still manufacturing band saws like the jimmy you are working on. interesting to see. can not put the link directly in comments but if you search for the term (Largest Cutter Machine Making Process | How Unusal Big Cutter Machine Are Made ) you will find it . thanks!

Nice work bud.

Looks good!! Also liking your weight lost !!

good job.

now that's a arbor press!

That little puny press..... Haha... I know somebody that has a bigger one, just not quite finished yet, LOL

((BOOM)) Crushed it 👍

Impressive.

I often wish I could see the parts you build reinstalled, and the repaired device then returned to operation.

Hi Keith! Enjoy your work! Thank you! Was wondering about the status of the digital drive project for the Monarch lathe....did I miss something on it??

Keith,, nice job on the gear cutting,,, any news on the steam stoker rebuild,,or has it been finished and I missed it. ?? Regards Frank

Nice!! 🙂

Great work, I wonder why it wasn't made as a single piece though.

Funny the difference between the American language and English. Chips are called swarf here in the UK

Thnks for your videos, I really enjoy them. In this case with the coax indicator, I was under the impression that you can't use the actual divisions to mean anything due to the various lengths and angles you can set the pointer to (different lever lengths and cosine errors etc). Basically you are just after the least movement. I guess that if you DO want to know how far off you are in absolute numbers then you would have to rest the pointer on an edge and then move the table by a known amount to see what that know amount means on the dial with the angle used and the length of the pointer. Or am I misunderstanding how they work?

Nice. Just asking about the cost of something like that. I don’t have to do an exact number but a ballpark number would be nice just to get an idea.

I learn something hew every vid yoh piston k7eth many thanks I am now foing to have to add a coax indicator to my wish list lol

Just guessing: The pins were probably added after the fact when the maker of the machine decided that the keyway was a weak point. The key is stronger than the teeth, it seems to me, but it may be that the force on the keyway was causing gears to crack at the root of the keyway, and adding the pins was a production-run workaround. Or maybe it's the other way around--pins first and then the key. If it was a problem with the keyway, then machining the slot with a radius at the bottom should have relieved the stress riser at the root of the keyway.

Do you know why the big teeth on the spur gear failed while the bevel gear teeth look fine? It didn't look like the key sheared off, but then again, they had to pin it with the drill bits. Nice job with the pressing operations - smooth and steady - always better than hammering the pieces and pins.

Keith am I right in thinking that the key on the bevel gear was cast into it. If so that would maybe explain why the keyway slot in the gear you were replicating was an odd size. This may also explain the use of the towel line to prevent the failure of the key during use.

Those pins look like they are sticking up in to the gearway. looks like the matching angel gear is going to hit the pins.

A beautifully made piece. But I can’t help but wonder how this gear is used. Does it spin on a shaft (no bearing?) or is it attached to a driven shaft? If so, how? There is no set screw or hole for a through-pin, or key way. Am I missing something?

Do you ever get tempted to completely take the movement out of the needle when indicating a bore?

Another great job done Keith!! I would love to see the machine this is for. Any chance of that??? Art from Ohio

I would like to see the engine, too.

Why didnt you use threaded pull dowels in case they ever have to come out ?????

So it's done? Done with part of the dowel sticking up in between the gear teeth?

Maybe on some earlier repair someone decided that a key was not enough and added the pins?

What is the point of the dowels given that the key stops it rotating?

It is so strange to hear a machinist say, "Aw, it's close enough." 😂

Nice to see someone running one of these co-ax indicators at a sensibly slow speed.

👍👍👍

Why the heck does blue loctite come in red tubes?!

Did anybody else notice those chips coming out of the Durabar don't really look like cast iron chips? LOL you know you're a machinist channel addict when you start judging chips.

I hope that you are doing well. You have really lost weight.

What does this part do?
