Emergency Shaft Build for a Peddinghaus Bandsaw - Manual Machine Shop

[@TopperMachineLLC]

To clarify my comment on metric threading. In the last year I have finally been seeing metric threads coming into the picture more. This is the exact reason why I bought the new Lion Lathe as it is metric capable. I hate metric, mostly because I am not great with it yet. As with anything, practice will improve this. In the US we don't have metric lead screws so it makes it significantly harder. Again, it will get better with practice. I still hate metric, ad 99.9% of the jobs I see are standard. Almost all of my customers design in inch, metric is extremely rare here.

[@jdshqs]

welcome to the rest of the worlds gripe but in reverse. All of our machines need to be capable of imperial threads and feeds due to the random and odd job coming in that requires imperial. As an apprentice, we had to learn both metric and Imp. You hate metric? well the rest of the world hates imperial just as much.

[@EyeMWing]

Yeah. Sibling is a factory maintenance mechanic-machinist (in other words, a mechanic who is vaguely capable of making simple parts to 'it aint pretty but it should work' tolerances in a baby machine shop in the corner) and all the stuff that's starting to break now is metric - all the imperial stuff is either gone or the real survivors on the far end of the bathtub curve.

[@graealex]

The way I see it, machinists measuring stuff in thou ("thousands of an inch") is already halfway there. You guys were the first to realize that incremental operations like machining or lathe work don't really work that well when trying to express it as a power-of-two fraction. Which is what metric is actually all about. The inch itself already has a metric definition of 25.4mm. And as a machinist, you might also recognize the beauty by which you can simply order your 4mm, 5mm, 6mm, ... tools instead of 1/16, 1/8, 3/16, 1/4, 5/16, 3/8 inches.

[@billshiff2060]

Metric is crap for machinists. Great for mechanics wrenches. I do both and imperial is better for machining and metrology. .001" is perfect for most everything .0001" for fine work is just right. The resolution of the metric system is clumsy and impractical, forcing machinists to count by 5's or 2's or some crap in between. .1mm is too big .01mm is too small and .001mm is way too small. The use of commas is idiotic, I'm sure they did that just to be "different", very french. Not to mention that thread chasing dials are near impossible on metric lathes, which are standard in imperial lathes, because metric threads are not whole fractions of the master lead screw. Most people don't know it but UN threads of UNC UNF UNEF are designed to give an increase in fastener strength of 15% between each grade. Metric threads do not have such a thing because their pitch availability is so awkward and the bodies that set the standards have never been able to agree on what pitches should be used. There are pitches used by DIN that are not used by JIS etc and vs vs.

[@graealex]

@@billshiff2060 Talking about .001" increments being a benefit of the imperial system, completely missing the point. I think in the whole history of machining AND metrology has no one ever missed the point as hard as you.

If you get mice in the fall or anytime. A good mouser cat is what you need. My second cat was a barn cat. I got her when she was a kitten. She was the most friendly cat I ever looked after. At the Vet for some unknown reason,she became Devil Cat would go ballistic. She was also an excellent mouser. She would regularly catch house flys in flight. Every fall we would always get nice. There was a huge salt marsh across the street from my house. One time our Tortoise Shell cat named KitKat waited at our stove for over a hour. She patiently waited for the mouse to show itself . She brought the mouse to our TV room. She tortured the mouse for at least 15 minutes and then ate it. I felt horrible for the mouse. But it’s a Cats natural instinct to play with mice before they eat them. I was heartbroken when she died. Anyway I also really like all your videos.

This is how we have excelled as a country for 2 centuries. Our craftsmen and their skills built the Chrysler Building, Empire State, Hoover Dam and other marvels without lasers, computers, GPS or other golly gosh whiz bang tricks. The computer they used was between their ears with simple instruments some of which have been used by sailors for millenniums such as sextants built America using the skills of artisans. Not the AI rage as we seem to be going head long for now. Make men and women smart again. DO NOT let AI train AI with the knowledge men and women have amassed over millenniums. Keep the human mind as the source of inspired and impressive knowledge. Topper and his work ethic demonstrate how important that is!

[@kamper4140]

I love all threads including metric. I enjoy it. You know you can disengage at the shoulder on metric too? You just have to disconnect the half nut in the relief, shut the spindle off, and don't touch the carriage. Then back out the cross slide, put it in reverse and hit the exact same number on the thread diall to bring the carriage back to the start. The key is never move the carriage after you disengage the half nut and make sure you hit the same number on the dial when going in reverse. It works I do it all the time on lathes with a brake not clutches if I'm worried about hitting the shoulder.

[@andrewwells7845]

I been a machinist for 35 years doing both imperial and metric what I see a lot of on KZbin is a lot of people turn the shaft and machine both ends I was always taught to machine in one to keep everything concentric no one use left hand tools to machine back from the chuck keep up the videos 😊

[@mdlanor5414]

As usual well done job. Your videos are very interesting. You do a lot of one off jobs. Jobs that many machine shops would not be interested in .You definitely saved this company a lot of money. By not having to wait 13 weeks for the manufacturer to make this part. I’ve noticed that many of the parts you manufacture are either obsolete or extremely costly from the manufacturer. Please keep up with making videos.

[@royreynolds108]

Have you ever tried thread-cutting from left to right with the lathe running in reverse and the tool upside down to help do away with the anxiety of crashing? It is slick. The only concern would be if the chuck easily unscrews.

[@The_DuMont_Network]

Now why didn't I think of that? A little awkward, mayhap, but does away with crash anxiety... Thanks!

[@TheMetalButcher]

Josh, for a lathe like yours without a brake, I would disengage the half nuts like normal, kill the lathe, restart in reverse, and then catch the same number going out. So long as it's always the same exact spot and you don't lose what rotation you are on, then you're good to go. You probably know this. If not, works well for metric to a shoulder. Noah

Glad to see you back. I have a metric lead screw lathe - makes doing metric easy for me - a bugger on imperial threads. In Australia they changed us over to metric a few years ago, although there are still a lot of imperial threads still kicking about, even in new machinery. I got a new Bridgeport clone mill, it is internal threaded in imperial, found out the hard way, bought a Z axis power drive ordered metric threads.

[@NetNielo]

In Australia the metric system became standard in the 1960s ... Not a few years ago. Metric is more accurate and easier to work with than imperial. America's system of length measurement is based on the metre and before any of us were born... It's time the US started using metric like the rest of the planet.

[@kimber1958]

you’ve gone along way in convincing me I could hang up a shingle And take on some of these simple jobs I sure would like to have a milling machine though before I started excepting anybody’s jobs. Thanks Josh

[@TopperMachineLLC]

I know I make it look easy, but I've been at it 10 years and finally making some headway. Most of the world is stupid and think you need CNC to make anything. Try convincing a new potential customer otherwise is the hard part.

[@kooldoozer]

Kimber, I would not out and out say this is a simple job. Straight forward, yes. But being productive and hitting your numbers and geo takes experience and knowing your machine. I occasionally run bigger work like this, and it takes a mindset and concentration over and above what the small work does. Not to mention the power of that big lathe and kill you quick. I never fall in to the mind trap of thinking a job is simple. If I do, I would surely blow a number or worse, get sloppy and get hurt on the lathe. Josh makes it look easy. And it is if you have done it a bunch. I know that you are getting comfortable with your P&W and that's awesome. Play with some big shafts and get a feel for the dynamics of the job, and really create a thought process for a work plan sequence. Notice how Josh zeros his DRO at different times, and switches between rough caliper and fine mic measurements. The cooling when NOT running trick is neat. I never thought of that myself. But much less mess, and I hate coolant mess. Anyhow, keep it up and be safe and always approach a job with a serious plan. I myself get a little lax and lazy using the small Hardinge HLV lathe. But a 20" lathe is no joke. We all need to keep this in mind. Peace. ----Doozer

[@kimber1958]

Thanks Dooz. I hear ya

[@d6joe]

13 week lead time? Ouch. I would have ordered two parts from you. One for spare.

[@scottturcotte1860]

That's Peddinghaus for you. In their defense, they do make top notch metalworking equipment, but their service and repair and programming/learning resources, and flying techs and parts in from Germany, don't lend to quick and/or easy turnaround on downed equipment... the people who sent this work to Topper are similar to the people I know who use Peddinghaus... they only deal with them when it's absolutely necessary... and Topper could probably easily make 2 of these shafts for less than the price of the Peddinghaus replacement in a fraction of the time... Topper simply beats them in both money and time economics, which is kind of laughable to such a company with a global reputation who built the machine! But it's not much different than having to find aftermarket parts for a 15 y/o auto because the OEM isn't interested in anything but selling new cars... the way of the world.

[@ssboot5663]

Thanks for the videos! ...I have not owned a lathe for very many work hours of ownership but have had one for a while.(farm use and hobby) I am afraid to power tap or power thread(dies) anything for fear of destroying taps and dies. The broken tap will end up stuck in my new hole forever and i would have to remake the part!

[@TopperMachineLLC]

I have been doing it for so many years, and I have had tons of broken taps. biggest thing is to listen for it to start binding and stop. If it sounds off, it probably is. Worse case, you wind up with a broken tap and have to start over on the part.

[@ssboot5663]

It would help if I threw away my worn out taps!(: Is there a tap meant for power tapping and are they different than the hand taps I'm using?

[@ellieprice363]

@@ssboot5663 Yes, hand taps are designed different from machine taps. They’re tapered on the end for ease in starting and have straight flutes. Machine taps have short spiral flutes on the starting end for a smoother “shearing” cut that greatly reduces torque and breakage. Use quality taps, low speed, and plenty of lubricant. It never hurts to go slightly larger on tap drill size, especially in stainless and tough alloy steels. Sharp taps with no worn or broken teeth are a must.

Josh I have to agree with you on the metric system nice job on that part

[@dan-o9746]

Awesome service

[@lwilton]

Suggestion for those metric stub threads where you have to pray the lathe coasts down before you hit the shoulder: do it the Joe Pie school of threading way. Flip the tool upside down and put the lathe into reverse. Now you are threading toward the tailstock, away from the shoulder, and only have to worry about accidentally trying to thread the tailstock. :-)

[@TopperMachineLLC]

Next time I will. In 20 years I only crashed into a shoulder once threading. But this idea will eliminate any chance.

[@doug3458]

It's tedious cutting away from the chuck if you can't disengage the half nuts, which is likely when cutting on an imperial, inch lathe.

[@punishr36]

@@graealex Run the lathe in reverse leave the nut engaged regardless of what pitch again unless it is a very long thread. Flipping the tool upside down only works if the threading tool has a constant undercut and does not work for a shouldered part and which is another pointless setup which takes time. It's no different than thread grinding. I merely stated that lathe hands don't use the nut and you got your nose out of joint. I wasn't even talking to you. You are not a machinist. You are probably a hobbyist and deffinetely a troll as again I was not speaking to you.

Thanks Josh, another great video. Don't be afraid of going metric. I started off hating it when it was first introduced (into Australia) but I actually found it much easier once I got used to it. Question: Why did you cut the thread relief after cutting the thread?

[@graealex]

Well, the reason most of the world uses metric is because it actually is easier. This shows particularly when machinists talk about "taking another 5 thou off" - while that thousands is based on an inch, that is actually a metric way to express a distance or a thickness, as a decimal point. So the impedance mismatch between large diameters expressed as for example (2 1/4" stock) and expressing smaller incremental operations (40 thou) already exists for all people working with imperial, while it is non-existent in the metric world.

@@TopperMachineLLC It’s easy to convert all the metric dimensions to Imperial. Metric / 25.4 = Imperial. From inches to metric is; Imperial X 25..4 = Metric. 2.375 (Imperial) x 25.4 = 60.325 mm.

You just haven't seen how quickly you can set up and program a part on a VMC with a tool and part probe...

@@Sketch1994 I wish I was confident with technology. I bought a brand-new CNC plasma cutter last year for my workshop. After three months of frustration, I gave up and shoved it into the corner. Can’t get my head around the computer programming stuff. I was told it would be simple and easy to learn. It wasn’t.

[@Sketch1994]

@@davidcat1455 The control layout makes a huge difference in ease of operation and the knowledge level required, while cheaper stuff are meant to work by cobbling random tech stuff together anyways. I hope you didn't buy a lemon but I've seen tons of sheet processing machines with a workflow of 30 minutes from design to program to setup to part

I grew up with imperial. Then Australia went metric. I can work with both, but I mainly use metric when measuring with a tape measure. But I can never get around a person's height in CM. Tell me in feet and inches and I know how tall they are. We used to use stones and pounds for weight, but metric weight in Kg is a lot easier. Bearings are nearly always metric, but I had a manual transmission that took a bearing that was metric outside and imperial inside. Never seen that before. Even though Australia is metric, some things are imperial and will never change. Try finding a metric tire. If you get a new car that takes metric tires, it's way cheaper to buy new wheels and imperial tires. I knew someone in this situation.

The finish on that 1045 looks really nice. Does it machine considerably nicer than 1018? Gotta chuckle about the tapping tribulations! Been there done that!

[@TopperMachineLLC]

1045 isn't as gummy as 1018. If that makes sense. I prefer 1045 over every other grade.

[@nschelling6420]

@@TopperMachineLLC Thanks! Still learning all this stuff. Yes, gummy describes 1018 very well. I’ve worked with Stressproof; wonderful stuff to turn compared to 1018.

1144 is awesome. I do hate 4140 Prehard, but that is another story.

Great vid again Josh. Nice to see you come over to the metric Darkside now and then. PS, I think you were in a rush when you did your thumbnail lol.. Emergeny?

[@TopperMachineLLC]

They were hot on me for this one. it was a bit of an emergency for them.

MR. TOPPLER, LOVE THE VIDEOS. TIRED OF ALL THESE OTHER SO CALLED MACHINERISTS THAT WANT TO USE THESE CMC CRAPS. SO GLAD TO SEE YOUR DOING IT THE OLD WAY HOSS. THE WAY GOD INTENDED IT TO BE. I JUST HAVE ONE RECOMMENDATION HOSS, WE HAVE GOT TO GET YOU A COMB. THAT HAIR IS WAY TOO WILD TO LOOK PROFESIONAL. THANKS AGAIN MR TOPPLER FOR KEEPING THE GOOD VIDEOS COMING OUT. GOD BLESS, JACK JOHNSON

Hi Jos, a black cat and doing metric and imperial , you must be a wizzard, greetings from Amsterdam

[@davidscott4928]

I notice no grinding or heat treat. Not ever needed?

[@TopperMachineLLC]

Those services are better provided by specialty shops. Most job shops actually don't have, nor want to do that in house.

[@dermotkelly2971]

Good job Topper I used to love one off jobs like that. Better than making 20 of them lol! Did you have a good camping trip?

[@TopperMachineLLC]

We had a great time. A little wet weather, but still relaxing.

[@glennmoreland6457]

Good ☹️🇬🇧

[@johnnyholland8765]

Good old fashion get it done machine work. I despise metric threading also but sometimes it is a necessary evil. Do you charge expedite fees? Lot of shops do. If you have to "drop everything" for a drop in job you should be compensated for your inconvience..

[@TopperMachineLLC]

Yes, and most of my customers even tell me to charge more yet. Lol.
