Well, that certainly explains everything. I have a small lathe with change gears and have been reluctant to mess with them. Now I feel like I can make changes like the big boys. It isn’t rocket science, it’s just a good explanation. Thank you.

Good morning Mr.Pete. i can't speak for anyone else...but i enjoy every second of your videos. Keep them coming please. Have a wonderful weekend.

[leecarroll]

Love your videos, takes me back 50 yrs.

Good mourning mr.pete, great video wright up my alley on my southbend. Thankyou 😎👌

Mr. Pete, you have your nuts mixed up on the gearing when you change out the new gearing ratio. The thin nut belongs on the stud gear. You have it on the middle compound gear. The thick nut belongs on the compound gear. And yes, there is a washer behind the nut on the screw gear. I know this stuff too well from all the years of changing out gearing on the 9" SBL cutting threads. Dad was a stickler on this stuff just like Mr. Pete! Yes, I watched the full video and paid attention in class today! Thanks for sharing, Ken

[worzyno]

You are a machine Mr. Pete! Very productive.

[angelramos-]

Yes, we like this video.Back to basics.Thank you.

You must have been the world's greatest shop teacher. My shop teacher didn't go into things to the depth that you did. He was also the agriculture teacher.

Thank you for this, any, and all your videos related to lathe gears and quick change gear boxes. My Clausing 5914 engine lathe came in buckets and getting the gearing to match the threading chart is my last hurdle. You may not directly address my issue but your videos have a tendency to educate me to the point that I can. Thanks, again!

This is why you are the inter-web shop teacher thank you Lyle.

[peteengard]

This is why you can find them set for .003 and have a tailstock die holder. Thanks Mr Pete.

Good morning Mr Peter.
I apreciete the information in your videos. Thanks a lot.
Cordial greetings from Mexico.

As always, thank you, Mr. Pete, for a very informative video. I’ve been looking for a South Bend lathe in my area for awhile now, and hope to join the community soon! Merry Christmas!

[slypig]

Thanks Mr Pete, it like being back at trade school, so many years ago. We got told to use news paper to set backlash space.

I have only changed my Atlas change gears once for the very reasons you demonstrated in this video. My Atlas has a beautiful OEM wood top base on cast legs. I like its originality, but the wood surface limits mag base attachment points for my indicators. Your steel table would be a welcome upgrade to me for function, but I have been loyal to the Atlas design. I see very few OEM Atlas bases. I treasure mine. It is a pretty handsome upgrade for an otherwise pretty basic and light machine. We set up my feed selection years ago in very cramped and poorly lit shop conditions. (The machine now has a well lit and spacious new home.) The feed is way too fast for good finish. This video encouraged me to set it up for a better universal finish and to get back to a long delayed LeBlond rebuild that I began years ago. The LeBlond is a true industrial machine and has a feed gearbox. It is also much larger. It deserves to be in use instead of being an aborted rebuild project... Too many projects...!

Lyle, thank you for this video. I have an old (1911) South Bend 11-inch lathe that is a model C -- your explanation really helps with understanding how to change its gears. Now I just need a set of 14-1/2 degree gear cutters so that I can machine replacements for the missing/incorrect change gears I ended up with when I bought the lathe! Then I'll be changing the gears as you demonstrated. ;)

Also, I remember reading somewhere (in a book, not on the Internet!) that notebook paper makes a good spacer when setting the change gear clearances.

That South Bend is a nice gift that's for sure, Tubalcain, great to see you explaining the gear change operation, definitely makes me appreciate the quick change in my SB 13"

[timmeh]

it seems to be ironic in my life that about 3 months ago i bought this exact same lathe which is kind of a niche machine becuase of its age. and you sir made a video of just what i needed to know at the same time. thank you Mr tubelcain!

[richwest]

Really appreciate the series, Thank you Mr. Pete. I bought a 9" SOUTH BEND LATHE model C from a neighbor about 12 years ago. Covid was my first opportunity of time I had with the machine. I'm not much of a machinist, but I always wanted Smitty's lathe if he ever sold it. I did get a quick change gear box in the deal, but it has never been fitted. I look forward to watching the entire series.

[AmateurRedneckWorkshop]

That makes me appreciate my quick change gear box even more. Thanks for the video keep on keeping on.
