South Bend Lathe Restoration , Part 12a (Apron)

[@MyLilMule]

The downside of breaking something is you have to fix it. The upside of breaking something is you get to learn how to fix it. Lathe is coming along great!

[@KevinToppenberg]

Yes, it was nice to feel that I could fix what I broke. But a lot of it was embarrassment of showing my mistake!

[@KnoxMachining]

Looking good!!

[@KevinToppenberg]

Sure is, with a little help from my friend! ;-)

[@christinepryor5893]

This one piece looked harder to work on than the other parts combined! The frustration was palpable, for sure. I liked the side by sides with you shaking your head over what you had done. Again, I am a sucker for good editing. Yikes , those five stages are for real. Although I didn’t catch any bargaining, you must have kept it private. 😄 Hope the next part of machinery is a little nicer to you. How nice to wake up every morning to that property- so pretty! And I did like your colorful shirt.

[@KevinToppenberg]

When I got that frustrated, I probably should have stopped and waited a day. It might have made me look for that hidden set screw! It's not just my property, East TN is just a beautiful place to live! :-)

[@anissawood4882]

I’m finally caught up! I enjoy the juxtaposition of the trials and tribulations in the workshop with the peaceful beauty outside. Good job using suspense to create interest; I kept thinking “when is he going to discover that missing spring??”

[@KevinToppenberg]

Wow! I'm extra impressed that you caught that before I mentioned it. Thanks for being a super watcher! :-)

[@anissawood4882]

@@KevinToppenberg no way! I didn’t catch it until your voice over, but watched for it afterward. I’m nowhere near that observant sadly :)

[@KW-ei3pi]

Awesome Kevin. I love the way to talk us through your thought process. Very interesting. I have a newer model SB, but the Apron seems to be the same. On mine, there was a huge number of wicks, but I saw only the two you show at the end. Is that all that came out of yours in disassembly? Could you be missing some?

[@KevinToppenberg]

I put back all the wicks that were there originally. But I bet you are right and I was missing some. I didn't have a manual that showed me what it should be like. I don't run it very hard. I hope it gets by without them (fingers crossed). Thanks for the feedback.

[@jeffanderson4979]

The best results I’ve had with taper pins is sudden impact. A large ball peen hammer with a drift will send those pins flying across the room. Trying to use a clamp or a soft blow won’t provide the impact required to bust her loose. Beautiful property

[@KevinToppenberg]

So I should have been using the sledge hammer on that and not on my gear fork! LOL! For that pin on the inner gear (the one I left alone), I did try a regular hammer. But I didn't want to bend the shaft so didn't go to wild on it. Thanks for watching. Regarding property, TN is a very beautify part of the country, and I am thankful for being able to live here. :-)

Hey I know that guy! (Billy)

[@KevinToppenberg]

I was talking to him last night and he told me that too!

[@WinkysWorkshop]

@@KevinToppenberg Billy's a great guy. He build the controller for my CNC wood lathe and it works great!!! Ask him about the Wimshurst machine I made him. The turnings on the machine were made with the CNC lathe.

[@KevinToppenberg]

@@WinkysWorkshop That Wimshurst machine was the first thing he told me. I think it has counter-rotating wheels and capacitors -- builds up a electrical charge for quite a shock!. Do you have a video about it?

[@WinkysWorkshop]

@@KevinToppenberg The start of this video is the machine I gave to Billy. kzbin.info/www/bejne/l325nYlmg5yMZ7s

Oh, sweet pie o` my... If you think that carriage is heavy... I have a 2.5 tonne surface grinder by Elb and a Schaerer UN450 lathe which is 2.7 tonnes... Both i bought as a rescue, as they would otherwise been thrown, and while some work is needed on every part, the carriage of your baby Bend is pretty much lighter than my tailstock... I moved it with no aid, but with enormous struggle... It has around 60 kg without quill and its leadscrew with handle, which add up another 10 kg, making it a 120/150 pound thing on its own... The carriage i dont even know how heavy it is, i am finishing a crane lift to be able to work on it further, and on the grinder, as nothing on it, apart from the screws, weighs less than 80 kg... Dont get me wrong, i commend you for the fine works thou hath done, but just know that that little apron is a walk in the park in regards to difficulty maneuvering it about... And i feel your pain with the paint removal... Except my lathe is again so much bloody larger that i still have to even disassemble it once the lift is made to finish the paint removal... Let alone go through what you already have with bondo and the rest of the good stuff... Huffin fumes and getting a free high... At least there is some benefit to paintwork... Regarding the clutch... My lathe has a similar thing, but different in construction, but its not meant to switch between either thread drive and rack drive, as you have to disengage one to engage the other. The clutch is there to allow you to set a hardstop on the ways and let the carriage be rack driven and crash into the hardstop, slipping and stopping the drive until re-engaged... The situation with two nuts and such is a tension mechanism that is supposed to be set to allow lathe to work and not disengage the rack drive when the cutter hits the work, but to stop and disengage should the carriage land on the hardstop, as to allow easy setup, quick safety and so on... Find a manual for your lathe, i doubt that the clutch has anything to do with drive selection, as you have to do that by engaging a halfnut lever or engaging a piston or what not to get the rack drive...

[@KevinToppenberg]

Wow! Your project sounds amazing. But also really difficult! Best wishes and I hope it all goes well for you. Thanks for the feedback!

[@camillosteuss]

@@KevinToppenberg Yeah, and guess what, i just today picked up a 1000 pounds of cast iron Thiel Contourex, removed its workhead and am in possession of a machine base to strip and repaint, also, i picked up a Sarlah drill press without a quill, also in need of a resto, so now i have 4 machines to restore... Dear Lord, i should stop leaving the house before i get a jig grinder... But I picked up the Thiel as to slap an internal grinder`s hydraulic headstock(already have it) to it and make myself a hydraulic lapping/polishing lathe as i despise the idea of grinding on a lathe with a proper bed... So yup, i now have 6 tonnes of machines to strip, fill, paint, scrape for precision(the thiel is amazingly good, factory scraping, leadscrews, ways, bushings and such are almost intact as the machine became obsolete quick after it was made)

[@KevinToppenberg]

@@camillosteuss I hope you are going to make some KZbin videos about all this! 🙂

[@camillosteuss]

@@KevinToppenberg I am considering it, as i know that most of machines i own have no videos on or about them, and should anyone get one, they will be blessed beyond expectation to find a video archive of how to for that machine, as i would have been... But i am lazy for such work, and i am constantly considering when to or if i should film what im doing, as the shop is either such a colossal mess or I am and would likely fail to provide the quality of material i want to provide, should i decide to do so... As you manage to do... I`ll see, maybe i`ll prepare a camera holder and the rest and film some, as i just put each machine where they are gonna sit and operate, once finished with resto... But for today, its smoking and tea until blondie releases a new vid...

Trick,put a washer on pin cut with hack saw,drive pin home

[@KevinToppenberg]

It's been like a year since I worked on this. Can you remind me what I was struggling with? Thanks for watching!

[@RizwanAli-qm2gn]

And chak my lathe machine

[@KevinToppenberg]

where?

Well I think I deleted my original comment on accident! Hopefully you can read it somehow! Im not typing that all out again! But if you somehow can see it... feel free to post it here in reply if u want??

[@KevinToppenberg]

Hey, thanks for your reply. Unfortunately, I don't know how to view a deleted message. I'd love to hear your thoughts if you want to try again? Best wishes.... Also, I have had trouble in the past with trying to post with a link to another site. I think KZbin automatically deletes those.

[@cobre7717]

@@KevinToppenberg okay so I took out the no no parts on my 15 inch southbend apron. It was the worm gear that you avoided messing with. Mine was very sticky and all jacked up because paint got in the oil holes in the tray built into the casting under where the cross slide screw is. Those steel pins were pushed in and I didn't want to to machine a tiny screw press to get them out so I drilled the pins out and it was a pain. There is a felt wiper in there by the way. On mine the cross slide nut is different than yours. It has .600 play.... hopefully the screwbisnt too worn out.. I got a new cross slide nut from ebay for a 13 sounthbend it has the right LH ACME threads. And on mine it has a 3/4 in diameter counter bore into the nut. My lathe is 48xxx something serial number which puts it around 1931 as I recall on the Steve wells page of serial number spreadsheet. It is a 88c catalog number. I saw that yours is a 188c. Mine originally was line shaft powered and now it has a cool cast iron motor bracket that was an option from southbend. Ill try and take a video of it but my hands are always way to filthy to record anything the last week. I am going to send off to grizzly and see where it was originally delivered to. I know it was somewhere near Milwaukee. i got it from a friend who got it from a friend who got it from somewhere in mke area. Its pretty cool that yours came from bridgport ! There is a lot of heavy industry in Milwaukee in the 30s so im freaking g excited to see where mine came out of! There was so much sludge and swarf and junk in that poor gearbox. Now I know about the second set screw on the fork. So THANK YOU for breaking yours and telling / showing us. Haha.

[@KevinToppenberg]

I wanted to clean that worm gear, but just couldn't figure out how to do it. Sounds like your lathe is awesome. The crossslide screw wasn't terrible to replace. I know there are some on Ebay that do it for a fee. Best wishes! You are welcome about breaking my fork. Glad SOMEONE got some benefit out of it! LOL.

[@cobre7717]

@@KevinToppenberg I finally got the worm gear out. Luckily i had a silicon bronze propeller shaft with the right diameter and similar keyway from a 1950s Chris craft cabin cruiser. otherwise there was no way in hell to get it off. Now I just wonder if this lathe made that shaft. If any asks it definitely did.

[@KevinToppenberg]

I don't understand. How did the propeller shaft help get that worm gear out?
