South Bend Drill Press Pulleys Repaired- Weld & Machine

- One of our viewers is restoring a vintage South Bend drill press and both of the pulley flanges had chipped places in them. We welded up the broken out sections then set them up in the manual lathe to machine them back to specs. #abom79 #southbend #machining #manualmachining

I went to an antique car show today and got into a long conversation with a fellow show participant who was a machinist. Thanks to years of watching Abom79 videos I was able to carry on an intelligent conversation with the man. Not only did I possibly find a local guy to do any machining I might need, I could tell he enjoyed talking with someone who appreciates what he does. Thanks for the education Adam!
The perfect scenario: buddies owning a welding shop and a machine shop next door to each other 👍👍
Oh great a 1 hour long video of awesome metal working from Abom! cant wait!
I don't know why, but I find machining threads always facinating and relaxing. Such a beautiful job done, like always.
Thanks for the repair work Adam. The drill press is up and running like butter! 🍻
Loved today’s master class in restoring old parts for continued use. Thanks for the expert commentary as you progress through all of the steps and the rationale for each operation. You are indeed an excellent teacher of your craft. Thanks from an old hobbyist still learning the craft since acquiring small machine tools more than 30 years ago. 😉
Thank you! I love these manual machining videos. The CNC is fine as well but I really love the way you explain the thought process that goes into the manual work.
Nice, just like the original videos, real manual machine shop repair work!
Adam making a nicer mandrill than any south bend drill press has ever had for the pulley. To fix a pulley. Love it. Adam you should send that off with the pulley so they can put a bearing on it and replace the pulley shaft with that piece of art.
Interesting, I've not come across that spelling before. At work, we always have known them as mandrels...
@@globalrezzanate9399 You probably aren't going to the same clubs. :)
perfect content from a seasoned mechanic
That dial indicator with the pivoting head is slick
Great video, Adam. Thanks for sharing. And thanks for helping out Chris. 👍
An hour of manual machining. 😎
My dad would have loved the 21 st century Dykem you used. I remember the smell of the stuff when he was doing layout work on a part.😊
Keith Fenner calls it "Sharpem".
You probably already knew that.
@surlyogre1476 nope, first I heard that one!
Sounding very locked in, switched on in this video Adam, very fast paced and focused.
Whatever it is that you're doing that's new, is obviously working for you. 🙌🏻🤝🏻🤝🏻🤝🏻
You do some really nice work. Love the machine shop and tooling. I learn something new every time I watch one of your videos and for that I am very grateful. Thank you 🙏
That indicator is freaking AWESOME!!! Now I need to go see how much they cost. Thanks for sharing.
OMG - manual machine work - Yay-!!
Thank you Adam!
good one Adam like watching your videos thanks Rich
Great job, Adam 👍👍👍
Machinery handbook should have the V groove angle.
Great job Adam , lol I've got a set of pullies for a 1978 buffalo drill press that need fixed also
Thank you for the Content. Hyperlapse video speed with normal speed audio is an extra step in video production. So enjoyable to not worry about the frequency of cutting noises going into Dog whistle range for headphone users.
Very nice. Thanks for sharing 👍
I love those Walter mx22 holders! I use them all the time since we got them.
Glad to see a new video
Who is glad???
Beware that the V groove angles on a pulley are not always the same because they vary slightly with the diameter. Small diameters ask for wider angles, larger diameters ask for narrower angles. This has to be with the way the V belt profile changes when it wraps around different radii
Beer and chips ready......lets go..
Don't forget to put the set screw back in!
Excellent project. Thanks!
Adam, about setting up the sheave angle by measuring the others - According to the book the groove angle is different depending on the diameter. For instance, for a 4L belt section, the included angle is 32° for diameter 2.65" to 3.24". 34° for dia 3.25" to 5.65" and 38° for dia over 5.65". Might have been able to reduce the amount of material removed if the angle matched better? My reference is 30th edition page 2528 if it matters.
18:30 .. I like the blue Sharpie!! .. Looks just like the, "Starrett Blue" ... fast drying, machinist's dye! :)
I love that you play TOOL on Instagram with your machine work. Pneuma!
The first setup was done using an Arbor.
The second setup was done using a Mandrel.
An Arbor has straight diameters, shoulders and threads to mount the workpiece.
A Mandrel has a taper to lock up the workpiece.
Arbor - Straight.
Mandrel - Taper.
😁
Hey Adam, any progress on the new home pad, and new shop ?? Been with you for a while now.
Yes sir... Thread releaf looks better... And it makes sense...
39:26 crack at the base of the pully to the left of what you are cleaning up.
It was a paint line. I just scraped it off with my finger nail. I was very nervous running to the garage to check though! Thanks for the heads up.
@@chrispy3866 ? That was your pully he was working on?
@@MrWizards1974 yes
The other side of the V grove is cracked shown at 40:39
Thanks for the heads up. It sure looked like a crack. I just went and looked at it. It was a paint line. I scraped off the paint with my finger nail. No crack. Phew! Certainly thought it was also! Lucky me!
17:26 .. the radius is good for this application too .. as the pulley will be forced against that edge for support while cutting!
Good evening
Good stuff
Nice to see hand lathe work again. Real engineering, I always think it’s superior to cnc
until the break positive point of mass production strategies
Nice work 🔝✅👏
Surprised abom didn't say something about it... I know he noticed that...
This may be the longest machining video for the amount of material removed in the history of youtube
Hi, i think i see a crack on the next sheave over.
Tell him to apply a bit of heat before putting the bearing pullers 😂
What year was the picture of you, your Dad and your Granddad taken? How did it happen that the 3 of you posed for a picture?
Chipped his franistan
Must be the SNS
👍🏻
not sure why you wouldn't use the angle on the groove that was welded so t blended closer , also , doesn't the angle change when diameter of the pulley changes?. give some age on those pulleys & no one will see the repair at all
Nice work as usual but I really think you could have stretched this into 2 episodes, maybe even 3.
Isn't it1/2 :-13
I could have done it faster with a single non handle file and flip flops.
Gezus..an hour for a pully fix.

Please post a link to your awesome channel with half a million subscribers. I'm very interested.
One hour for this repair.🤔🙄 No wonder that nothing works in the USA.🥴😵💫😂😂
Video would be more enjoyable if you would break it down into 2 or 3 videos. This one is too long!
This is hardest and most complicated way to fix step pullies that i have ever seen!!! I welded and hand ground these things with a die grinder faster than using a lathe and all this madess like 20 years ago!!! It would probably would have been cheaper to buy new ones rather than go through all this nonsense!! Maybe you make more from the video and needed content but WOW!!!!!!
And I bet your hand ground pulleys looked exactly like I imagine - a bodged up repair that showed you didn’t care. You completely missed the point of this video, which was to demonstrate some fairly simple machining and work-holding techniques for relative beginners.
y
You're watching a channel for machining and you're complaining about someone fixing a problem by machining. WOW!!!!!!!!!!!!!!!!!!
I retired from there 5 years ago and the damn thing is still working!!! 25 year fix!!! it needed new belts 3 years ago!!
@@buckhorncortez YA it probably cost more for all this crap than to buy a new set!! Obviously you never worked in a machine shop!!!
If you don’t have a lathe that is your problem !
Boy this is uninteresting content creating you used to do much better
Go away dude
16:50 This is a GREAT tool!! .. Very versatile!! lots of support! ..
Heck you could easily custom grind a radius or grooving tool if you didn't have time to wait for an order to come in too!!
ALSO?? It'd be easy to re-sharpen then just raise the tool a bit .... .. same idea if you ran out of inserts!!
