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.
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.
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.
I would think that the pins would be better for, well, shear pins, than a cast in key. They can be replaced whereas the key would need to be milled off and another key way cut into the bevel gear. I am suspecting a field modification of some sort though. I grew up in farm country.
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.
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.
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.
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.
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!
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!!!
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?
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.
I know right. I’ve seen guys run them really fast. Should be run on back gears on the slowest speed. They really don’t even need powered at all. Take it out of gear and spin the spindle by hand. Just like the good old test indicator.
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.
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??
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.
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.
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?

Great show today Keith. Always a pleasure to visit with you.
Not only do I like your videos every time, I frequently share them in homeschool groups to get kids interested.
Thank You Keith for detailed account of keeping “old iron” running
Another good one Keith. Thanks

That,s a thumbs from me I appreciate the time you put into the videos thank you Keith
THAT, is a satisfying thing of beauty.

Hmmmmm…..
Although I can’t see a .400” (steel ?) key shearing before a cast iron gear tooth…
Robert
I agree completely, with my experience with Machinery I went straight to that as the source and the root of the problem
I would think that the pins would be better for, well, shear pins, than a cast in key. They can be replaced whereas the key would need to be milled off and another key way cut into the bevel gear. I am suspecting a field modification of some sort though. I grew up in farm country.
Sounds right and the 400 thou sounds like it was a 10mm key!
I would bet it was a double guarantee that the two gears would stay together. The cast gear teeth proved to be the weak points in this assembly.
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.
I've been looking forward to seeing this part!
Awesome!! Scratch this one off the list!
I hope we can see some video of this steam engine somewhere down the line.
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.

Good job! Best regards from Dresden! 👍👏❤🛠😎
Really nice job Keith. Your customer should be really happy with that.
Fantastic work, as always, and very well explained
Most impressive work. Thank you, Sir
46+ years in machining and first time seeing a co-axial indicator. Good grief why so late to the game. That is slick !!!
Turned out great!
Enjoyed watching this. Perhaps cutting a helical gear in another vid. Thanks very much.
Thanks Keith. Great content as usual .
I’m always impressed with your work!
Nice job Keith, it look like a work of are. Thanks for sharing the video.
Happy Friday 😊
Great work, thoroughly enjoyed this.
Nice job Keith! It looks so simple, but that’s because you have a ton of experience!
Well done as usual.
The finished part is very pretty really. If it were stainless you could use it as a machinists hood ornament .
fantastic keith love to see you make gears!
Thank you
Very interesting, well done.
Good morning. Very nice project.
Nice job!
Nice work as always
Nice work Keith.
Excellent job.
Thanks for sharing. 👍
Great job! Enjoyed each and every step.
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 Keith. Nice job. thanks for the videos.
Really nice work Keith. Thanks for sharing.
Great video as always Keith! 👍👍
You might consider Loctite 609 or 620 for this application. These are retaining compounds as opposed to thread lockers.
*- 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.*
thank you I really appreciate what you do
Great job Keith!
Very satisfying to watch. Thanks for sharing..

Thanks for another great job and video.
Nice job
Thank you for sharing👍
Brilliant. Thanks.
Another great video. Thank You!!
Thank you Keith , brilliant job 👌🥇😊
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!!!
Nice job on the gear!!
Awesome job! I learn something every time I watch.
Looks good!! Also liking your weight lost !!
Beautiful work!
now that's a arbor press!
Thanks for sharing 👍
Thank you for sharing this
Beautiful work, thanks for sharing. :o)
I often wish I could see the parts you build reinstalled, and the repaired device then returned to operation.
Nice work bud.
good job.
Thnks for your videos, I really enjoy them.

Or am I misunderstanding how they work?
It would work just as well without numbers on the dial. All you’re looking for is the needle not moving.
I’d say those gear teeth are lined up dead nuts. 😊
Impressive.
I would like to say how healthy you look with your weight loss.
Thanks for your interesting videos.
((BOOM)) Crushed 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
Been wondering about that also, and the Metal planer, there was supposed to be a job to do when the planer was finished, but never seen any videos.
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.

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.
I usually put the spindle in neutral and dial it in slowly by hand.
Those pins look like they are sticking up in to the gearway. looks like the matching angel gear is going to hit the pins.
Great work, I wonder why it wasn't made as a single piece though.
Nice to see someone running one of these co-ax indicators at a sensibly slow speed.
I know right. I’ve seen guys run them really fast. Should be run on back gears on the slowest speed. They really don’t even need powered at all. Take it out of gear and spin the spindle by hand. Just like the good old test indicator.

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.

Another great job done Keith!! I would love to see the machine this is for. Any chance of that???
Art from Ohio
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
Funny the difference between the American language and English. Chips are called swarf here in the UK
Keith am I right in thinking that the key on the bevel gear was cast into it.

That little puny press..... Haha... I know somebody that has a bigger one, just not quite finished yet, LOL
So it's done? Done with part of the dowel sticking up in between the gear teeth?
That was the camera angle. You can stop the critisizing anytime! Do you honestly think he would leave the pin up in gear path??
@@paulcopeland9035 I don't have to stretch the imagination to see what the video shows
Do you ever get tempted to completely take the movement out of the needle when indicating a bore?
I would like to see the engine, too.
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?
Other people have said the key might have been snapping in use, hence the pins. It's a bit like putting a 30 amp fuse in when the 3 amp one blows !
It is so strange to hear a machinist say, "Aw, it's close enough." 😂
Why didnt you use threaded pull dowels in case they ever have to come out ?????
Hi, How much weight have you lost? You’re looking good.
👍👍👍
Why the heck does blue loctite come in red tubes?!
atte bottom ove the bevel thare looks like alinement marks
What does this part do?
I hope that you are doing well. You have really lost weight.
