THANK YOU FOR YOUR SUPPORT!
Interesting tour of your lathes Winky. Thanks for the video.
Thanks for watching!
Thanks again for sharing your knowledge. Keeps up the interest of the young folks and keeps it fresh in foggy old minds!
You bet! Thanks
Mr Winky, this was a very clear and informative video...thanks for sharing your knowledge......Paul
Thanks Paul, your welcome.
Nice job on explaining the basic operations of your lathes.
Thanks 👍
Great video and you did an absolutely superb job of restoring both of those old lathes Winky. They are beautiful.
Thank you very much! I love this lathe.
Great introduction to your equipment. Thanks.
Thanks John
I really enjoyed that.
Thanks
These machines are works of art - very beautiful. Nice introduction. I'd like to get into some machining - looks interesting.
I agree. They were designed to function and look nice too. There was obvious pride involved.
Ive got a south bend 13 and have worked everything out for myself, but it was really good to watch your video to reassure me what I worked out was right... I really need to get into screw cutting and your bit about the feed gear box was very informative ....thanks for a great tour.
Thanks great. Threading is both fun and handy. I also have a video on this using my Logan. czcams.com/video/vS5UmtxstQE/video.html
I agree, nice job of explaining the operation of the older lathes. You sure do have two beautiful machine tools.
My 1941 SB 13 was my pride and joy. Lost in a fire.
My new lathe is a more modern Clausing Colchester 15x50.
It took me a while to figure out how to use it. The clutch and auto reverse of the cross slide and saddle are sweet and I like the gear box that threads imperial and metric
Thanks! You Clausing sounds like a nice lathe!
Thanks Mr. Winky!!!
Your welcome Mr. Wilsher!
You done good Winky
Thank you sir!
Great video...thank you very much.
You are welcome!
Thank you I just bought my logan 1810 about a month ago.
If I remember right that is a very nice lathe
Thankyou i just picked up a 1957 type c hurcus machine all manual gear . On the good side i never used a lathe before so learning hopefully wwill not be to hard. I just neec to learn about where all the gears go / intetchangeable. Someone sent me a pdf manual for it so now its just a matter of try and learn . Your v ideo was very enjoyable Andy Australia
Sounds like a new adventure. Your welcome!
I say this vid was spot on ! You have to know what the controls are for and how to use them before you pick up a piece of metal stock and try to turn it into something .. Great share , Should help out a lot of folks wanting to learn ..
Thanks Shawn!
Nice job, your old Logan is still chugging along. Used it today making shoulder bolts.
That's great! Good to hear from you.
Thank you! I just got my old senecca mills lathe up and running. Still some fine tuning to do and learning on my part with such an old lathe. I'm sure I will get it dialed in soon!
I had to opportunity to buy a Seneca Falls lathe. Several years ago. It was a beautiful lathe but it was missing too many parts
@@WinkysWorkshop yeah that's unfortunate. It's a pretty solid lathe for its age.
I refurbished a 12" Atlas Clausing and went all out on the restoration like you did. It feels good to have one. well 2 actually I also have a 12 " Atlas Crafstman, so I get it LOL
Yep... love restoring these machines
That was interesting, I like your videos sir Winky. I'm in the UK so was bought up on old Limey machines such as Wards. I served my time in the 60's man handling big old mangles machining truck engine blocks, gearbox casings and making millions of valve collets 😁. Now only have a small bench lathe and Seig bench mill in a single garage, very little space but great fun.
Shop time is the best! No pressure or deadline like the old days!
@@WinkysWorkshop yes indeed, even the swarf splinters one gets regularly in the fingers are worth it.
Keep up the good work. I like your practicle approach to making stuff 👍.
Thanks that was perfect. I have the same Logan and didn’t understand the clutch operation.
Thats great, thanks!
Even owning a pair of lathes I find your take on them interesting. I installed a quick change on my Atlas, then had to go back to the gears for a project, OVEY. I had to make a new Banjo for it too, not sure how the old one cracked. I have a Sheldon too, and I love it. Yesterday I made 5 new sheaves for a telescoping antenna mast, replacements would have been $35.00 each, a good savings for a couple hours messing around in the shop.
Thanks... yeah, it's fantastic to have tools like a lathe and mill. I should have got them both long ago. It opens up all sorts of possibilities!
Thanks Mark.
Very welcome
That was very informative.
I would love to see a video on threading on the Southbend since I have one similar.
Thank you for the video. :-)
Here's one I did on my logan. czcams.com/video/vS5UmtxstQE/video.html
Good video. I have a 1943 10" South Bend and the controls are very similar to your Logan. I think things became more standardized as time went on
Thanks, you are probably right. This one 3 way control on the carriage is a pain to use. Otherwise I like the South bend about as much as my Logan.
Nice to see. Top model compared to my single SB 9C.
I'd have a hard time choosing between the two lathes.
well done 👍👍😎👍👍
Thanks
My uncle had an older lathe with a 6' bed, and the feed screw was badly worn, so he took the screw out and turned it around, and it worked well.
A friend of mine had a lathe that had a 3 speed automotive transmission on it, and it served him well for many years until his shop burned down. I would have loved to get my hands on that after the fire to see if it was racked from the fire, and if so, how badly. Sadly he junked it without knowing.
Six foot is a big lathe. I've heard of people flopping lead screws... it probably works very well, especially on a lathe that long!
@@WinkysWorkshop I'm guessing that it was used in industry, that's why the lead was worn. He built a stand for it, and he had it until he passed away. I'm not sure what it sold for, but he had the reputation of not doing things halfway.
Interesting to se such advanced lathes. My is with no quickchane gearbox and only a halfnut in the apron.
My Logan 200 was like that. I used it a lot but I'll have to say... I really love the quick change!
if you still have the logan 200 I'd love to find out if you can swap aprons. I have a powr kraft with only the half nut and would buy an apron asembly for the clutch drive and slower feeds if its a simple modification
The 200 is long gone but it only had the half nut as well. I implemented an off the chart gear arrangement that slowed the feed about 30%. but no way can I remember how I did it.
Hello Mark,
An interesting video... will you be doing one on your milling machine...
Take care.
Paul,,
I'm not sure about the milling machine. I need to watch a few videos myself! Ha
wish I had seen this kind of video before I bought my used Grizzly. The Grizzly is ok but having to change gears is a hassle versus being able to used levers. And my G0602 doesn't have the separate clutch nor power cross feed.
Where did you find your lathes?
I got the Logan several years ago for $325 but it needed a lot of work and then the South Bend I got for $100 which was a very good deal but it was in much worse shape than the Logan. I had a logan with the change gears, you're right.... the gear box is a big plus. Here's the South Bend rebuild and then the Logan. czcams.com/video/vrXBkqC6ttc/video.html czcams.com/video/u7WBN17lOiQ/video.html
Winky,I have a Logan 200 that I just got. The belt needs replaced but the old one was in pieces. How do I determine the correct length?
I think the Logan manual has it in there.
I think this WAS part 2 !
Part 1 should cover:
The concept of turning (inserting an item in a 3-jaw), have it power rotated and cutting into it for facing and turning operations.
Slides: Saddle, cross slide & compound slide
Tailstock: drilling
Work mounting: alternatives inc. between centres - explain the benefits of each method.
How to set the depth of cut - for facing and turning
Range of tools with demonstration of 3 types inc. boring bar.
Part 2 (this video) covers feeds and speeds.
Part 0:
The concept of turning - making round things - samples such as stair rails, table legs & small metal items
Materials: woods, plastic & metals
The Lathe, turning and safe operation of - hazards - PPE - precautions
Other parts: boring, threading, strange shapes - mounting. Maintenance - cleaning & lubrication, special accessories.
Just a thought :)
Very Good point. I had a couple of people asked about the controls so I did the video. I'm not sure I agree with you 100% but it would have been better to start more basic. Part 0 is a bit overkill I think. I guess it depends on who's watching but most people wanting to learn about a metal lathe probably have some idea what it's used for.
@@WinkysWorkshop Unfortunately, people like us with experience forget just what we know and the fact we had to learn somehow. And as you say, many will come knowing a little and some will come as they've heard the name and wonder what a lathe is.
I've seen it many times before with othe subjects they make good efforts but then make a leap because the bit they leap over is too obvious to someone with experience.
I've been thinking about your first comment. I do think describing some of the lathe components would have been a good idea but it also depends on where a person is starting from. Short story: My job used to be running a web offset press. At one point I was on a crew of 7 starting up a fairly high tech new press. The crews were sent to a plant where they had a new press running for hands on training. After our press was running I asked out roll tender how to run the auto threading function at the reels. He said, "You set this selector to A, hold this forward switch until this green light comes on, push the remote button and then put the AB switch back on B". I asked him, what does the AB switch do? He replied, "I have no idea". It was easier to learn a random sequence. For me, the random sequence was a different language. I needed to know why I was moving the switches. The BEST education I ever got on a lathe was rebuilding my Logan 200. It was my very first lathe and after the rebuild I knew what every function did. For me, learning the drive and gearing on a lathe is a logical starting point.
I taught hundreds of training classes before I retired. Mostly on press component maintenance and belt splicing but, many have told me that the way I taught my classes was much better than any technical classes they have ever had specifically because they understood the inner workings of the machine they were working on.
@@WinkysWorkshop 'Learning' is an interesting topic ! My older brother did far better at school but it surprises me how much he's forgotten that I still remember from school. If I don't understand a bit, it means I don't understand the whole.
I've never 'not understood' anything about lathes. Having said that, I'm intrigued by the rotary clutches on the aprons of your lathes. I have seen those briefly before but never come across them - always simple levers on lathes I've used. For example, removing a chuck on your lathe, although you never said anything of the kind, I'd know how to use the back gears to to stop the spindle rotating.
Similarly, I can make 'new things' food-wise by modifying a 'known food'. With having an engineering background, I have little problem understanding machines.
Depending on what you've been breathing from presses, you could be a good candidate for getting testicular cancer. My dad was treated for cancer in the mid 1970s. Around 1980 in the school library (not doing what I was sent there for) I happened to read that people working with oily engines and printing presses commonly suffered from testicular cancer. I mentioned this to my dada and he was surprised I'd found out !
@pmailkeey Lathes are fairly simple machnically. I guess that's why I like them. Here's something we used to control gains on web presses. I didn't understand it at first but I got it now. czcams.com/video/bzRh672peNk/video.html
You sure keep a nice shop. What do you do for a living
He is now retired, used to work at a printing shop, running and modifying the printing presses.
Dave summed it up! Thanks Dave
Thanks for this Mark. What belts are you using on your SB?
That belt was left over from where I used to work. They were going to toss it and I took it home. Part of my job was overseeing belt installation in the pressroom. I have no idea what belt it is but it was free. There is much better belt for about $4 a foot but you have to have the right glue and a very expensive hot press to install them. I've thought about selling the belts but the heater is the problem... about $800 or more.
@@WinkysWorkshop pressroom as in printing press?
@@DavidR8 Yeah... I ran a web offset press for years but the last 15 years before i retired I would on machine improvements, belts and training.
@@WinkysWorkshop Thanks Mark, my father used to own a print shop. Professionally I used to do print checks, currently building up to have letterpress shop.
Ink is in the blood!
@@DavidR8 Most of what I ran was 32" double web Harris/Heidelberg M1000. It was long count magazine press. Most counts were 150K for 1.3 Million. The press delivered two 16 page signatures at 1700 FPM. I also worked on a Goss M3000 with a 54 inch web. It was a newer press than the M1000 but total garbage. After I went into a tech service job they installed an S3000 with a 72 inch web. It was much worse than the the M3000. It's hard to understand why Goss is still in business. The older presses were made much better and took a lot of abuse. I used to work in a small print shop between age 18 and 21. It was all single color although we ran 4 color a few times. Web presses are amazing bu I always dreamed of running sheet fed again. The best part about sheet fed is that in most cases you are the only person running the press. You can maintain it and keep it in very good shape. The web presses ran 24 hrs a day with 4 crews of six people. Maintenance was only as needed in most cases.
How do you keep your lathes so clean! 🇬🇧
Well... the South Bend was restored about a year ago so it still looks new. I used to have a huge mess going all the time but now I am retired. No hurry... I just clean up when I make a mess. It's more enjoyable really.
@@WinkysWorkshop It is so much more enjoyable to work in a clean organized shop.
@@andyZ3500s - I agree, and I have no production goal so I keep it clean.
You made me nervous with your fingers that close to those moving gears. You need a mr Pete pointer stick. Nice intro to lathes. It's funny how on a basic level all lathes are the same.
Yeah... it would make me nervous to see somebody else point to gears too.
Hi Winky, interesting, I did n't know it was so quick to change a flat belt speed. These older lathes were I think better built than some modern ones. Sadly a lot of modern 'import' lathes do not have a back gear and it is a disadvantage. A modern variable vector variable frequency drive can overcome this to some extent by 'fattening' the three phase sine wave it provides to the motor - this increases the torque at low speeds and needs a motor designed for use with a VFD.
Thans, I can;t imagine a lathe without the back gear. Threading would be a challenge!
hi my friend, your lathe is very sexy I have to admit. Great art of engineering.
I agree, it's art
Constructive feedback, I hope. At 12:45 you forgot you were teaching. "This right here" is not a helpful description. It took half a minute before you started trying to say what it accomplishes. It is important that a student knows where to "file" information like how it moves. Without knowing anything about function, many people will just forget it. Later, you went over the three positions several ways.
Yeah... I could have done better. I should have called it a level or mode selector. I think I somewhat redeemed myself when I moved to the Logan. Somebody else said I should not have started with the drive and gears. I did this for two reasons, one I had a few requests from people to describe the apron controls and two mechanically minded people sometimes think and learn different. I'm getting a little off track but for me, I need to understand the mechanics before I can retain other labels or random information. I do agree, the lever should have had a name but I suspect the name is the least important aspect for most watching the video. Also... I'm learning too. Short story: I used to run a web offset press with a 7 man crew. We were starting up a new press that was very high tech and we (the crews) all went to another facility to learn on a press that was already running. Each person had an area. Mine was the units and and the roll tenders had the reels etc. Anyway, I asked the roll tender how to run the chain drive to thread the paper. He said, You turn this selector to B, press this green button and then hold this lever until the chain stops. I said, what does the green button do? He said, I have no idea. For me to retain the knowledge I needed to understand what the green button did. However, this guy didn't care as long as it worked.
So anyway... I'm sure I lost a few people and you made a good point. When and if I do a part two and three I'll make sure I have a name for each component. I did watch the video again... I thought I was consistent between the two lathes although I did add the part about the half nut being locked out but them said it applied to the South Bend also.
