- Опубликовано: 28 авг 2024
- This short video shows my approach to machining the small oil cups required for the Crank and crosshead slide. These parts are small, but don't have to be scary. As part of my process, I will single point the 2-56 threads. ( at 770 RPM ) Take a look !

Thanks for being honest about it taking you an hour to make the first one. Some creators make things look a lot easier than they really are and then it's very discouraging for us home hobbyists types when we go into the shop and it takes us days to do what someone on RUclips told us took them 15 minutes.
The first one of anything always takes longer, just the nature of the beast.
Brilliant Joe:- 46 years a machinist, own business, CNC machines turning out aviation parts etc etc ,yet here you are grinning like a schoolboy over a miniature steam engine just for the fun of it!! I LOVE it!
The joy is in the journey!
"you can buy this part for $2.50. *WE* are going to use thousands of dollars of tools and hours of time..."
immediate thumbs up and comment from me. thanks!!
Thousands of dollars in equipment, material procured, and man hours used to make a $2.50 part. I LOVE IT!!!!! I once spent 8 hours making a motorcyce part that cost $12.00 new, but mine is soo much cooler.
Thank you for telling us the first one took over an hour. You make everything look so easy but it took a while for you to do it.
The truth is, the first one took 47 years. 1 hour to setup.
Making all the little accessories like oilers fittings and valves is really a great fun challenge that many model makers seem to skip. Really enjoying this series.
Thanks John.
Great to see you guys all making steam engines, I can't wait for TOT to start one
thank you for saying the first one took over an hour. It makes me feel a lot better.
Brilliant! You make it look so easy but that's the skill of the professional.
Thank you very much!
I am thoroughly enjoying this series...especially your explanation of how and why you are filtering, holding, what feature to cut first, etc!!!
Thanks. Thats just as important as knowing how to run the machine. Maybe even more so.
Those are really beautiful parts. Much more satisfying than the $2.50 mass produced ones.
Thanks Joe, I really enjoy seeing your setups and your perspective.
that floating arbor trick is a good one, worth keeping in the back pocket.
Thank Joe!
Great video, Joe.
I'm in the fortunate position at my job where I can give the tiny parts to the youngsters with good eyesight ;)
Seniority (and age) has its benefits sometimes 😁
Dude, you are a rock star in machining. This retired 68 year old engineer salutes you. Great series!
Glad you enjoy it!
And adding the time to grind, stone and characterize the chamfer and single point threading tools for brass, to the actual time to fab up the part, it's still really cool. Bank that $2.50! Cheers.
why have 2 people not liked that? sterling work as usual Joe.
your eyes are better than mine . Joe that was amazing and thanks for the video's
Opti-visors are a MUST when your eyes start to fail. Most machinists have at least a couple pair in the shop.
Thousands (or 10's of thousands) of dollars of equipment to make a $2.50 part! Tell it like it is!
Yes, but you can make 10's of thousands of that $2,50 part
"Wasn't 12 minutes the first time though, HA no it wasn't" Story of my machining life
This series is so great. More please.
That was a joy to watch. It must have been a challenge to film though. I'm glad you said how long the first one took! 😃👌🇦🇺
Wow.... Presler is here.... like your comment and your channel
His sticker is on my wall around the white board.
Mark, I setup and filmed the first one then reviewed the video. My fingers influenced the auto focus and the entire shot was in and out so bad, I had to do it over. The second one benefited by the setup and number recording from the first one. I have to make 2 more and bet I'll shave that time in half by #4.
@@joepie221 Joe, I use a Sony Handycam and I find the autofocus is so good it follows the chips as they come off the part. I sometimes forget to disable the autofocus and my camera rig is up quite high so it is a pain to manually focus the lens. I appreciate how you are honest about the time it takes to do a part. Honesty and integrity are in short supply sometimes on RUclips.
Regards,
Mark Presling
you take it to another level! looking forward the rest of the parts and finaly a runing beast of Engine! nicely done!!!!
You are my go to guy for no BS straight info. "Wasnt 12 minutes the first time " lol
Good show good info as always. Thanks papa joe
Very Nice!!!!
PM Research just put in a order for 500 Pieces
Automatic Screw Machines, for the win. CNC can't do shit against them.
Made me happy to know it’s not only me who takes an age to make the first part and then knocks subsequent ones out a lot faster.
Hi Joe,
Was a pleasure watching you machine that oiling cup. I remember when you machined the miniature cocktail cup. You and the family stay safe.
Me too. That was just as impressive as this job.
I love it!! Why waste $2.50 when you can make it.....Right?😂😂 Awesome video Joe!
It's all about the "I made it". It only took an hour to grind the tooling, and a few hundred dollars to buy the collet chuck and collets and that tap, but I saved $10.
I could never count the hours I've spent making something I could easily buy. Usually I do it to hone a skill required to make the part. Thanks as always Joe. (and there was no stinkin' math in this one! : )
Hello Mr Joe, if you have tooling and decent machine tools, this is considered a hobby. And it keeps your hands and mind busy. I will continue to see 👀 your different projects. I'll enjoy it coming in place.
Perfect part for a screw machine. I could of made those pretty quick on my dsm59 turret lathe, as lonk as you would want 100 of them. Really nicely done.
Thanks Randy. Under magnification, I was a bit disappointed with my hex collet. The corners were not as sharp as they should have been. It effected the concentricity a bit. As for screw machines and turret lathes, great machines. I worked around many B&S and swiss screw machines during my apprenticeship. Cam driven. Amazing.
Interesting, fabulous.
I need to do this for my PM #7 next week.
You are Mr. Wizard sir.
Thanks. How are you enjoying that #7?
Master craftsman.
Although single pointing the threads is impressive for 2-56 I have always used a threading die to make these small oilers for my engines. The reason other than the brother of changing lathe gearing, is that it results in a stronger part by not having a concentric relief cut around such a small diameter.
That was the coolest machinist flex I’ve ever seen... hella good work, and now I have something to attain to.
thanks for showing the best sequence of operation on this tiny part
👍Wasn't 12 min. the first time...Ha! 👍 Itsy parts are a PIA! Great job, Joe!
Joe Pie with the speed run! Love it.
Look at the bright side, Joe. If that part can be sold for $2.50 and your machine and tooling is ~ $25,000 you only have to make 10,000 to break even. At 15 minutes a part working bankers hours it would only take you 312 full shifts...and on the 313th day, you can knock off at lunch time!
Keep the content coming, brother! This native Texan appreciates the knowledge you're sharing.
Only 312 days, thats something to look forward to.
I'm not a machinist but just watching you do this makes me regret not taking it up when I was young I'm always amazed thank you
Thanks again Joe, I like the rough cast look on the castings.
Oh, that was just poetry in motion!
I was happy with the results.
i like that, many of my projects could use some decent oil cups..... thanks again for the info
That is a thing of great beauty and skill. Well done and thank you for sharing the project with us.
You should make some spring loaded hinged lids for these oil cups to keep the dust out. LOL
I was actually thinking that the caps need to screw in, and have a retaining chain on the inside, like many oil cups. Probably would have to get a jeweler to make the chain. An added feature might be to make a stopper that lifts from the top of the cap to turn the oil drip on. Just making more work and ideas for you Joe.
I took your advice in making a floating arbor for drilling small holes from a previous video of yours. I had to make a few propane jets for a custom application using #69-72 drill sizes. Exactly how you said, you can feel the drilling process, hence pull back when you need to. I thank you for that valuable information. Drilling such small holes was new to me at that time.
Hi Joe. Really good to see some small precision work. I have some oil caps to make that are missing from my loco’s valve gear and this explains the process in detail. I’m enjoying this build and getting so much out of it. Thanks for producing this series. John 🇬🇧
Glad it helps. I plan some good stuff in upcoming videos. I hope you'll comeback.
Beyond words! Good video!
Having collets for the job makes all the difference . Nice job..
Cracking job Joe!
Loving your build. Inspiring to all.
Thank you
oh just a thought, Joe has a vid on a rig for doing tiny drills in the tailstock. I wish I'd made that
I see a few of you guys all building these at the same time, but so far yours is the most impressive. Good work mate
Thanks a lot!
The most impressive thing is that he made it upside down!
Good to see you having fun 😊
As a long time subscriber, I notice a new ‘spring’ in your step 😁
Great video as always, you truly are the master at this, teaching all of us how it should be done. Thank you
I appreciate your long time support. This is different material for me and I am having fun with it.
LOL, I love the description between purchasing these and making them. Good one fella ! 101K my friend, WELL DONE TEACH. What a sweet, wee piece. Looks like it was purpose built. Another well done for you this fine day eh.
I would not even try this. Great video as usual. Steve.
Hi Joe. That shot of the threading is very well done. It's not easy getting such good close up views. BobUK.
Enjoyed this video. You made it look so easy. Why do I think it's not. Thank you.
Nice work as always. I have a smaller bench top Enco lathe. Tool lots of work to small work like you just did but thanks to your videos, its where I learned alot to machine rhe things I need to.
Biggest thing I use my lathe for is remaking carburator parts that can not be purchased. So small parts and small hole are just what comes with the job!! The sliding drill chuck was a great idea I use all the time when drilling with .35mm drill big. Its the only way to "feel" what you doing.!
Glad to help
That was fun, Joe. Mainly because about half of my shop work is making small parts for a seller of obsolete parts of a certain piece of camping equipment. Thousands of little parts. Like to watch someone else do it.
Smallest I've ever had to single point was 0-80. Sometimes you have no choice, but on your part I would have used a die and cut the cost of these little oil cups down to only $40 EACH. ;) Ha!
Nice display of the "backward is right ward" threading on such a tiny part. Thanks, and have fun.
Dean
It's mind boggling how you make such small parts. I am having trouble keeping track of overall project progress. Maybe you could start future videos in the series with a shot of all the finish parts on the workbench separated from all the unfinished castings and a list of other parts to be made (not from castings) such as the oil cup.
His lathe and bridgeport are tuned to perfection for this kind of accuracy. Spotless shop. Machines in "tune!"
I love that you made it instead of buying it Joe!!! Fricking wonderfull job and is teaching me alot about small work holding!! This is youtube gold dude..
I had confidence, so I had to give it a go.
Thanks Joe
Hi Joe,
Nice job... I think maybe you're going to become hooked on this model making...
Take care
Paul,,
Beautiful little oil cup. I'd be tempted to redesign it though, by moving the hex to the bottom of the cup, and then sizing and threading the cup barrel for a tire valve stem cap.
A tire valve stem cap is about twice the size, but I like the idea.
WOW! That was awesome Joe, thank you!
Joe you always amaze me! nice job
Thanks. It was a fun part.
Joe Pieczynski = Sensei
Joe Pie = Senpai
Wasn't twelve minutes on first one with a Ha! Got'a love it 👍👍👀
Got to be honest.
Hi Joe . Had to ware magnifiers watching got the old eyes LOL. Nice job.
Cheers Fred
I set my tools under magnification. No shame in that.
Thanks for the video Joe.
Learning so much by watching your videos. Especially setting up jobs.
The setup is everything.
Now for the oiler accessory an eazy out for the .040 hole. i am so impressed as always
You do a great jop of showing and explaining how to machine small parts! Thank You
Glad you enjoyed it!
This part reminds me of a fitting that our shop made for one of our customers.
Looking at the drawing it was easy to loose sight of the actual size of the part. The drawing is on an A size paper, 8 1/2x11. The part was drawn at 4X scale.
The material was 1/4 SS Hex Stock. It finished length was 0.611. Tiny part.
The
Its always bigger on the drawing. :)
As I’ve said before, you seem very much at home with small parts. That was very impressive. Being somewhat visually challenged I may go for the $2.50 part from PM. Very nice Joe!
Thanks John. Maybe check into an Optivisor. They come in handy.
@@joepie221 Will do Joe. I’ll look like Mr Pete.
Flashbacks of high school metalworking shop class! You even almost sound like my foundry teacher (High school was a while ago, lol)! The technique and attention to detail is amazing! Eagerly awaiting the next video.
Small is fiddly - love your approach Joe - so logical as always, and with the patience of a saint! Doubt I'd managed that in 12 mins... thread came out great.
just about to make 2....you made it look easy....thanks
You make things look too easy! Really enjoy your videos!
I had to make parts on a cnc screw machine once. It was .093 diam x .125 long. One end had a .0625 hole and the kicker a .010 thru hole. It was aluminum but still had to check virtually every part for a broken drill. I still like small parts though. LOL
Joe, another notch in the "outta the park" belt. Great job on this. Sometime if you are in the mood, a video on speeds and feeds for drilling and boring small parts would be great (and the associated considerations). I make carburetor jets on a Unimat Lathe, and I know from experience that when you get "small" (no Steve Martin joke there), it is much different than hogging out metal on a 8" piece of 4140. LOL. Well played and congrats on breaking the 100K mark! Well deserved.......
Thank you!
Ah, so even Mr Wires uses a tap made gauge sometimes! Nice job
I've always said if you will control the part forever, go ahead and use a nut or other means to do the thread. Since this is 56 TPI and brass, I'd also be afraid of distorting the profile with even the slightest of pressure using wires. But I am flattered you called me Mr. Wires ! Thanks Crispin. Stay well bud.
You sir are amazing
I learned the hard way about threading them after drilling a hole through them.
I made several of them and the first one I tried to thread it twisted it off.
I overcame that by putting loctite on a a drill bit shank and putting it back in the hole before I threaded them.
It was a pain in the butt however it saved me a lot of aggravation.
I hate it when people don't appreciate the time and effort that has gone into something. I'm currently making a knife in my spare time at work and the people there say "why don't you just go buy one?"....
I get it. Its just not the same. Its not about the cost, but the experience of doing it and the pride afterwards.
@@joepie221 absolutely, I couldn't agree more.
My grandfather made fishing knives at work (back in the 60’s) using different colors of acrylic in layers making striped handles. I have one of them.
@@joepie221 Some of it too is can you do it its the challenge of what will it take for you to make it right! How much rethinking will it take to make it work too! Not all us like to not take the challenge of its hard we like the answer well lets see if we can figure this one and and make it!
What to say? Well done, can't be done in a better way.
The next serie will be making a wrist watch I suppose? 1:13 hour to "save" 2.5$.....
Some modell railroad builders find an honour in finding ready made, but well made, parts similiar to this. There is soo much work building a modell that nobody built before, from scratch and time will pass. 3 years for a locomotive, 1 year for a car in the 0 scale, 1:45.
Cute li'l pieces :-)
And I love your comparison between parts cost vs production cost (just wish all managers could do the same).
That might not be so simple a comparison. How about the value of a now more-skilled worker from using something like this for practice? That could be ongoing returns to plug into the financial equation. It's indeed a balancing act, but you have to put all the correct stuff on the balance pans. Including the fun quotient; in some cases that's a thing too, as Joe points out.
@@DCFusor Those are important but I've seen to many cases of "doing it ourself" even though buying the part would be cheaper or sell it at a loss just out of stubbornness. Or simply not take in the complete picture.
It's crucial for a manufacturing company to charge for the work. Which is hard when the customer demands lower prices. But in my experience, they might whine but then they comes back and accepts. I've personally more then doubled the price AND kept the customer because I could motivate the cost (and the owner of the company preferred the risk of losing the order to sell with loss).
But lets get back to the parts in this video. Run them in a Swiss lathe and you'd probably have a cycle time around one minute (perhaps noticeably shorter). Not many can make these faster on a manual lathe then shown here (not me for sure). That's the effect of efficient mass production and something that needs to be taken into consideration - To make or to buy.
@@sharg0 So have I, of course - I'm no spring chicken. My point was "many cases" != "all cases". Leaving that completely out creates errors too.
Good stuff Joe, well done
W O W ! ! ! ! Incredible skill. Thanks for sharing!
I really liked the comment about $1000s of dollars of equipment and tools to save buying a $2.50 part. Nice work. As always👍👍
A beautiful job Joe nice one!
Glad you like it!
I was just going to press fit these things in. I'm using an old Atlas lathe and all the gears for threading are gone. But after seeing how well yours turned out I think I'll try a die. I know I would have drilled the hole first, thanks for saving me from sapping it off. Awesome work as always joe.
This week I learned; centre drill the tiny part, thread it M4, then drill it 2mm, because the die crushes the brass as it forms the thread. *I was making 1/4”-40tpi by M4 male/adapters. Five off.
I use to tell my boss all the time, "The first one is the worst one".
Nice....! I have made 2-56, buy never single pointed.... Good One!!!
I had to give it a go.
Guess it won't be checked using the 3 wire method?
@@waynespyker5731 No. Since I'll control the entire assembly, I'll use a threaded hole. You could easily crush the brass if you weren't very careful.
Wow, great video.
very very good joe
Fabulous as ever Joe. I like the time comments, it's always faster in a vid and I always feel I'm slow, so it is nice to hear how long the first part takes. Course it doesn't help when the dearly beloved says "Wow that looks nice but that didn't really take all day did it ?"
