Metal Planer Restoration 45: Machining a Crowned Flat Belt Pulley from a Casting
ฝัง
- เผยแพร่เมื่อ 3 ต.ค. 2024
- As part of the restoration of my circa 1890's New Haven Manufacturing Company Metal Planer, I needed to make a replacement flat belt pulley for one that was missing from my machine. Using patterns I created copying an original pulley from another machine, I had a new casting made at a foundry and in this video, I turned a new pulley on my Monarch metal lathe, including the crowned face done with a taper attachment.

You are an honest man. You could have edited your mistake out of the video. But you just dealt with it. And it didn't make any difference to the finished part. That's life!
Keith I appreciate you sharing the mistakes along with the successes. We learn as much from seeing how to fix things as we do from seeing them go right the first go 'round. What a legend.
You're a cool cat Keith, love your videos 😊👍
Don't be so hard on yourself Keith ! BOO BOO's happen ! and you managed to get rid of it too
so no harm no fowel ! (quack, quack ! LOL)
that is awesome Mr Keith
Nice work !
Nice recovery 😉
The only person who never makes a mistake is the person who never does any work.
Yeah, this is the kind of guy who eats germandude's lunch. The guy who gets the job done and for a good price. Expect 5thau error
Edit: with germandude i mean the man focus on "good nuff stuff" for practical use.
Germandude is the man who laps flat mirror finish with 3micron diamond lapping compound, just for being german And AND! To charge more because he is german and do the german gutt'n'toight way. German stuff is expensive, that is why this man is eating germansdude lunch.
but not working would be a mistake?

Corollary: The person who never makes a mistake is the one who never learns anything.
I wrote down a bad measurement this week for the position of a gear on a shaft. Not even a round number, something like 130 thou. As I was about to drill the pin it "just didn't look right". I assembled the old parts and re-measured, cussed myself thoroughly and corrected the operation before disaster struck. Sometimes you're the windshield, sometimes you're the bug... I'm glad your pulley worked out and look forward to seeing the planer in operation.
Being the bug, he avoided the windshield before going S P L A T. !!!
Good Job As Long As It Works
My tool and die teacher always said you won't make the little mistakes. Its the big ones that will catch you... Keith Rucker Hold my malted milk! Love your videos. Thanks.
I was taught a number of things by my dad a master carpenter
If you make an mistake fix it don't wait because it will eat at you until you do
The difference between a true craftsmen and an wanna be is not that they don't make mistakes but they know how to fix them
Looking forward to you next video
Any apprentice machinist would be more than fortunate to study under your masterful skill and knowledge Keith. To err is human, to admit it is a class act.
Lol 😆 🤣 😂 😹 idiot
You had one of those days "the dropsies" everything you touch turns to crap.
But you persevered & came out smelling like roses.
We all make mistakes!!! You fixed your boo-boo and moved on--that is a good lesson for us all... Thanks for sharing with the mistakes included.
Obviously the boo boo didn't matter - true craftmanship, you know you had a lot of lee way on the casting and it came good at the end. Thank you for sharing, Keith and stay safe, man!
That 3/8 bitt must be a good one you sure use it a lot as a starter for large holes.
That has been the story of my week. Keith you are a good man. We all have issues. Thanks for the great work.
Thanks kieth agreed with the commentator below " without mistakes we would not learn anything" Keep up the good work.
It worked out Keith ! Stop fretting lol we all make mistakes from time to time , some a lot more often than others ( me mostly lol) it's the real machinists that's show their mistakes and the also rans who hide them. So fair play to you!
Great video as always Keith! I agree that including the boo-boo is very instructive to us other mortals 😁. One flaw, however, no Ginger or Maryanne cameos! 🐱.,
I first learned of your channel when kieth Fenner used his tracer attachment to crown a pulley for you. I’m glad you can do it yourself now.
Keith, many thanks for your content contributions. Your videos are watched and enjoyed by thousands. Fun talking to you at the Bash and admire your prep work on Stan's mill and surface grinder prior to your scraping demo.
It's been a while since I've watched you again. Excellent work, Keith. I ran a 16 ft Gray planer for five years during the 70's. Interested in this rebuild. Well done.
fun fact: at 1.5deg taper for each 0.001 taken on the radius the end of the taper moves about 0.014" ! if it meets up with another 1.5deg taper thats 0.021", easy to go too far! Great video and thanks for sharing
"Everyone make mistakes " said the hedgehog as he climbed off the hairbrush.
Stealing that.
The one things I miss most about the building game where I started my working life is the ease with which mistakes cam be ignored, covered up, blamed on the materials or blamed on other people. Or in direst emergency claim it doesn't matter and is "full of rustic charm".
Houses built the mirror image of the way they were meant to be, houses a brick narrower at one end than the other, whole estates built in the wrong place by 20 metres so you have to move a boundary fence under cover of darkness to make room on somebody else's land... Been there... Done that :-)
@@AnthonyHandcock early in my career as a plumber I once connected an entire row of drinking fountains in a factory to the plant compressed air system instead of the water line. Hard to explain that away.
@@markmossinghoff8185 Like it :-) Was this some sort of substance induced error or one of those "How the **** did I manage to do that?" brain-farts?
I think the best one that was entirely my own work was the time I wired a large step-down transformer back-to-front and gave a machine 2,400v instead of the 24 volts it was expecting. Being good, solid 1950s technology and being protected by a 63A amp fuse it caused quite spectacular amounts of damage before the fuse blew. Luckily that happened after hours and I blamed it on a transformer failure. Well... It wasn't rally a lie. It was a failure to wire the transformer up correctly failure so it was the truth. Just not the whole truth.
Well, as a friend of mine often says to me, "Why are you the only one who gets to be perfect?" :)
I've been watching you since the wood planer project. This is the first time I've seen you make a mistake. It just shows that you are, actually, human.
Nice progress, can't wait to see it on the machine.
Hi Keith,
Hat's off to you showing the slight issue you had and well done for recovering it.
Have a good weekend
Paul,,
Great video. Learned how to do that and now I can go ahead with my pulley.
Hey, another great video . I always enjoy your skill and experience. everyone makes mistakes. a true craftsman often sees the mistake before it gets out of hand
As soon as Keith made the whoopsie, I was telling him through the screen to keep cutting until it cleaned up. Glad to see he took my advice ;-)
Telekinesis 😈
Crank the play out of the cross slide before your taper , nice job.
Just in time. I’ll be casting some wheels for a sander next week so learning to crown is perfect. Thank you.
Keith Rucker: "Let's Getter' Done"
Keith Fenner: "Hey, that's my line"
what does Blondihacks say..the Three Keith's lol
Fenner is a legend rucker is a hackkk
Keith, All of us old school engineers have our moments while doing the task. Some we can disappear others we call a modification as required by production necessity due to client feedback..
Everybody has those days.
Classic taper attachment problem, normally caused by not taking all the backlash out of the system. You can see the taper turning bar move a little when you run the carriage back and forth. They can be annoying like that!
No worries, good job.
No worries, good job.
Hiya Keith
Don’t know about anybody else but don’t see any mistakes except perhaps thinking you had one in the first place.
Great stuff! I'm gonna be machining some parts soon for a 12" jointer restoration on my channel. This gives me the confidence that I can do it!
Very nicely done. And no need to be embarrassed, we all goof up sometimes. (Of course, every time I do, I feel the same way you do about it, so there's a little personal hypocrisy for ya...haha!) But you fixed it and it came out right. Kudos to you for not trying to hide the mistake. We appreciate the honesty. And with all the wonders you turn out, only an idiot would pick on you for a slight miscalculation every once in a while. Nice job - every time I watch you do something like this, I learn something. Keep up the great work!
Keith made a really big dial test indicator out of a dial indicator lol
Glad you showed everything. Thanks. Made it even more interesting.
Gorgeous work, as always. Also nice to see even an old pro can make a "bo-bo". It's not a mistake though, as it cleaned up in the end.
Just an unplanned modification. ;) Looking forward to more on the planer.
Far from pro
Very good. One thing you can do is paint the casting before machining. Saves time on masking. (I hate masking :-) ) There may machined surfaces you want painted tho.
Nice save on the mistake there. Can't wait to see the machine up and running.
Keith don't screw up!
I may be wrong and most likely are. But i bet if you had 10 of those pulleys from the first 100 made you would have 10 different sizes. They were made by the same process as you just entertained me by for several minuets. But you cant tell me that some manuf. Machinest on a monday morning cared near as much as you did about the outcome. I bet that if they were within .050 original manuf that that was good enough. The overall effect on drive speed was not that critical. I havent done the math but i wouldnt think that .015 wouldnt change the operating linear distance much more than .050 per reveloution.
What a perfectionist. I would have just had a slightly wider chamfer on both sides to clean them up.
You know what they say: Short rows take 90% of the time.
Great video. Like you said, we all make mistakes. As my father often said, “The sign of a good machinist, is how well he can correct his mistakes.” That is exactly what you’ve done. I’ve been learning from your videos of a long time. I hope all is well at home, work and family. Take care. Well done!
Thanks for sharing.
4 major technical errors. Reaming way too fast. Lowest rpm possible use grease not oil on the reamer.
"Bozo moment" remarkable restraint in your choice of words. LOL
Rucker does crap like that constantly he's a hack
GREAT JOB, GREAT VIDEO, NOW ( LET'S GO TO WORK )...
We learn by making mistakes. This ended up as a good functional piece.
A joy to watch something without political content.
Keith I suspect that you still had backlash on cross slide. When you engaged feed there was a slight delay in cutting a taper until backlash was eliminated.
that chuck deserves some rust protection ja ... Nice job
Just proved he is human
Just exactly what I like about your channel - you tell it like it is. And we learn. Thanks Keith.
If you can't figure out what happened, then it's just plain bad luck. Everyone and their dog has those days (the puppers mostly when they don't get enough headpats) so that's that. Kudos for showing the mistake.
Cant trust a guy who always hides his mistakes.
This one was however a lucky recover.
Comment 4. I'm up too early.
If it is like my machine you didn't have the backlah out before yiu started over so it was advancing without the taper attachment responding due to the lash not being taken up yet. I usually cut my tapers outward when possible to avoid this happening. Better to take too little than too much. :-)
Bonjour Keith,
People who do nothing don't make mistakes :+) As small model builder, I like your world of huge machines, so accurate besides this and I can't wait to see your grinder finally operationnal again because I do not know what it is useful for. My concern is that I am not familiar with non metric measures, but I trust your skillness for your measures.
Amicalement, Raphaël
I wish all my mistakes were that easily taken care of! Nice job, it won’t be long now!
Well I was thinking about doing a bevel on some rollers to make a big belt sander, but my maximat lathe doesn't have that adjustment at the back side of my slide like yours.
Got to figure out how to do a bevel with what I got. Lol
I was "Why isn't he doing the outside sooner?"..right up until you mentioned it had a crown taper.
When doing the very first indicator testing to center the part in the four jaw chuck would it be a good idea to indicate on the inside so as to get a more even thickness of metal for better balance?
I'm binge watching the whole Metal Planer Restoration series and I'm shocked by the love, strenght and passion that you have to feel inside to become a master craftman like Keith is. This is just amazing.
Same
Lost motion in taper attachment? Did you pull the cross slide towards you before starting the cut? Just a thought from a guy with not taper attachment on his SBL ;-)
Hey Keith!
On the 'first' chucking, after reaming the bore, why not turn a clean-up near the expected crown location on the o.d. (to indicate to) and then re-chuck by the rim i.d. and finish ALL of the other face AND o.d. etc??
Ken
Rucker not that smart
It is nice to know cast iron parts can still be made in the USA. Thank you and Windy Hill Foundry for making replacement parts and returning vintage machinery to useful service.
You made a mistake, no problem!!!! I read years ago a good engineer discovers and corrects his mistake before it becomes a bigger problem!!!!!! Only a fool thinks he never makes a mistake!!!!!!
Thanks Keith - didn't realize those flat belt pulley's had a crown to them . ps BOZO is everywhere Ha Ha .
A flat belt will "crawl" to the highest point on the face of a pulley. The saddest thing is when some well-meaning "restorer" thinks the crown is due to wear and planes it off. (I've seen this done on TH-cam.) Then he wonders why his flat belt will never stay on the pulley.
For an obvious crown on a pulley, look at the belt pulley on old tractors. I had to ask my uncle about it when I was eight years old or so. Also why they always put a half twist in the belt.
Nice work. On this pulley, and the gear, I'm surprised you didn't paint the castings before machining... now you have to mask the machined surfaces.
Did you share it with Tom Lipton happen to.th best
Thanks for sharing all that knowledge.
THANK YOU...for sharing. Enjoyed.
I wonder why people always say, "don't forget" instead of saying, "remember to"?
Just goes to prove the old saying, "A man can't have enough tools." You need one of those pantograph attachments like Keith Fenner has so you could cut the crown on one set up. Get out the checkbook....
No he doesn't.
th-cam.com/video/iel8FAGTmvg/w-d-xo.html
Hey, everyone makes mistakes... what matters is that you know how to quickly and seamlessly hide them! lol
Another great job as always. For a finished look paint the rough cast surfaces dark red, black or whatever color matches the planer.
Why not use mandrel?
Keith, thank you for posting your videos. I find them interesting, informative and like to think I learn a little from them. Also, when I see you doing the measurements, math, geometry, trigonometry, etc. that your work involves, I cannot help but to think about some of the knuckleheads that were in my shop classes in junior high and high school so many years ago. They didn't want to have anything to do with math or science, just wanted to play grab-ass all the time and make fun of others that wanted to actually learn something. Caused me to take a different path in life and not pursue the trades. Kind of sad. Keep up the good work sir and thanks again for posting videos of your work. Happy Holidays to you and yours and stay healthy in these times.
Excellent work and practicle recovery from a visit from mr B.
HA! Your first comment: We're both up too early
Thanks for the teaching. Enjoyed the video.
buen trabajo..gracias por tu tiempo
No to worry Keith - everyone boobs the odd time.
Sometimes you’re the dog, and sometimes you are the fire hydrant.
Dammit.
Nothing that a good deep unnecesary chamfer cant solve
All I see is a beautiful part and a learning experience (for us.) Thanks Keith.
I've owned a 21.6 ft Jayco travel trailer for 10 years and traded it for a 2018 Keystone Outback which I currently own.
Your previous comments about RV owners needing to be handy and capable to fix misc. RV problems true, out of necessity. Out of frustration with complete lack of communication on the RV dealer's part, I will never seek their service again, unless it's a major appliance issue. I resort to absorbing small warranty costs by fixing them myself rather than seek warranty coverage at a dealer. So there is my dealer service example. Next is the manufacturing side: When you spoke about the shower tub failure, you gave the RV manufacturer a pass, because they don't own the part or appliance. Wrong! I'm in the quality & reliability business with automotive OEMs. The OEMs have standards in which suppliers must meet and maintain data that such standards are being maintained. Suppliers must meet R/1000 requirements and demonstrate capability through a PPAP process. The OEM must maintain awareness of failure modes and drive the supplier to resolve them, either with material corrections or process corrections. OEMs also apply a B100 life expectancy requirement of which the supplier must prove the product meets. The RV OEM owns or accepts that reliability requirement. Hence, the RV OEM has ownership responsibility on the items they buy from the supplier.
Next: please do not give the RV OEM a pass on poor assembly quality because it all is a manual operation and not automated. The fit and finesse of my RVs have been deplorable. The materials are substandard also with no durability. See my previous comment about B100 (B life).
Lastly, the routing and clipping in the industry is beyond acceptable. Wires and plumbing run in all directions with the goal of saving material costs by getting from point A to B in the short way possible. Behind any panel you pull off is a rats nest.
So I can go on and on, so I'll spare you and your subscribers. No wonder the outrageous MSRPs are discounted by the 10s of thousands. Resale value is nearly non existent.
I appreciate your channel allowing me to contribute since you asked for feedback. One last thing.....most all RV OEMs source the same suppliers, yes they do. Whether it's a $144,000 Beacon or a $16,000 Jayco Jayfeather trailer.
For those who are interested, here is an informative video from Steve Lehto.

Everyone messes up but it takes a good machinist to know how to fix it
Do you need lubrication when you cut the cast or does it machine easy without any coolant or lubrication?
You fcuked up more than usual Keith ....
Polishing the pulley will make it grip the belt much better when in use.
