Gear Repair: Making and Installing Bronze Bushings and Machining a New Shaft

The third part of a series of videos showing how I repaired and restored an idler gear that goes on a J. A. Vance Planer/Matcher that is being restored at the Georgia Museum of Agriculture. Shows machining and installing two bronze bushings in the gear and turning a new shaft for the gear to ride on.

I KNOW I'M LATE WATCHING THIS, BUT YOU STILL DID A GREAT JOB. THANKS KEITH

[JRo]

Excellent work. I love your demeanor, too. You approach the issues very humbly, almost unsure of what to do next. Obviously you're a master of your work judging by the results. I can only wish my stuff came out half as good as yours.

Watching Keith almost 10 years ago restoring this gear and shaft is a real treat! I am now appreciating why my Dad as a “Master Mechanic” always held machinists in such high regard. He probably would have been a terrific machinist given the proper training based upon my observations of his meticulous work and understanding of machinery. Sure wish he was with me now to watch and enjoy Keith’s skills.
Best Regards from St Marys, GA

Hi Kieth, enjoyed the video, nice work. A very useful tip when checking the screw cutting pitch is to mark a start point on the work piece withdraw the tool point, engage the sadle and run the lathe at a very low speed and count the number of revolution of the chuck relative to the desired thread pitch, stop the lathe and measure the distance the tool has travelled which should be one inch. I.e. Eight revolution of the chuck equals one inch distace which equals eight threads per inch. Very useful when cutting fine and odd numbered threads or when you don't have athread guage. A chalk mark on the chuck helps with the counting. If the work piece is small and the thread distance is less than one inch, you can put a sharpy mark on the bedway. Press and ruuning fit tollerances when making bushes with a thin wall is always tricky. I tend to finish off small bushes with an expanding reamer. Good luck keep them coming. Michael

I love the whistle of the steam locomotive in the background.

Fantastic!!! Your skill/s is really marvelous Keith since not every machinist possessed the talent like yours.I wish i'm like you.

[bbtjd]

Another inspiring video. Gives us new guys hope. Thanks again.

After watching the video on fixing Leo's threading machine and this gear. One tip you should be pressing your bushings first and then reaming to size. This will insure exact alignment and uniform size of the inside diameter. You mention that the alignment is not that critical, even a small misalignment will result in premature wear in the bushing.

i wish i could go back to school and start all over again .

[rogerbeaulieu]

Very nice video series, glad I was able to watch all at one time.

[KnolltopFarms]

Hey Keith, I'm just going back in time and watching some of your older videos, and it's been fun. You gave me a good laugh @ 10:00 when you say "You don't want any surprises on that 1st pass!", and after the great laugh, I had to wonder...yes, I don't want any on the first pass, but when would I want a surprise on the lathe? ;)

Happy Easter my friend, and thanks for helping to bring me into this world...Aloha, Chuck

[shobud]

I really enjoyed watching the steps you took in making theses parts ...
The completion of both the shaft & bushings are a perfect fit...
I can see from your work that you are a perfectionist and very skilled at it ...
GREAT JOB !!!
Wished you were local " I need a extension housing bushing made for a 3 speed Automatic Transmission in a 83 Toyota Corolla in
I have ordered several off the internet and they fit the housing perfect " but the new yoke I purchased for the driveshaft has to much play up & down - side to side when installed
Anyway great job on your project....

[jeffren]

Hi Keith, I enjoy your videos and hope to see that machine running soon. On a side note, I have noticed that the air nozzle you use is not an OSHA approved one with the side vents to limit the pressure to 30 psi. It's always something they check for at my work. Keep up the good work. 

[richardsalsbery]

I knew there was a reasen I liked you ...every thing done right

[quantumss]

Very nice Keith. You remind me of my school shop teacher ( a very long time ago ).

[michaelharris]

beautiful work, I am 69 and have access to a lathe. think i will start to learn how to use it while all of me still works.

[anthonytammer]

It's nice to bore a little undersize and come in with an adjustable reamer to ream to size. The finish would be a lot better: Boring leaves small ridges and after a short time those are worn away.

[VintageMachinery]

Yeah, I have thought about putting some music in there. I will have to search out a nice piece of royalty free music to use there. Easier said than done though....

[robertestes]

I have quite a bit of mostly home and gunsmithing lathe experience. I recently upgraded to quick change tool holders and now am considering going to carbide insert bits. I am good at sharpening my high speed steel bits so would like to hear your thoughts on the subject. The last job I did was to install a muzzle break on a ss barrel Weatherby magnum and I wasn't to happy with the quality of the finish.
I really enjoy your videos. Bob

Hi, I know my question is 8 years late but it's never to late to ask to learn. For the arbor repair, if one does not have the equipment to make a complete arbor, how about building up the low areas with weld then turn down to your needed diameter ? I for one have a lathe but not one what can do what yours can. A 67 yo Vet. Retired in Ct.
