Machining a Cummins Harmonic Pulley
HTML-код
- Опубликовано: 15 сен 2024
- In todays video we get to show off a small rush job for a client doing a Cummins motor rebuild. The diesel mechanics broke the part and the unit was backordered indefinitely. We helped them get the part then needed to get the rebuilt back on track. Enjoy!
Good work, You say you are still learning. Always strive to learn. You will become a better machinist. Jim
I hope so!
Great job !! I love the use of the mini boring bar, very nice! Thanks for letting us in your shop.
Any time!
There’s a lot to be said about CNC type machines, but there’s no beating the skill and enjoyment of watching a manual hands on machinest doing his craft. Love the channel.
I appreciate it
Very nicely done! Quality machining
Thank you very much!
You were not joking about those heavy cuts. Quality work as always
Yeah I like heavy cuts
I read this comment right as he starting doing that. I was like "Holy sh*t! He wasn't kidding!" Hahaha
I like it when a machinist knows what close enough means. (: That said, I always told my employees that, while it’ll never be perfect, the more you strive for perfection on every job, the closer you will be able to when it counts. Learning the difference is how you charge the customer fairly. Cheers!
Absolutely
Nice job! I fully support your method of using a non-critical job as practice for hitting your numbers. Been there, done it.
Much appreciated!
Heavy machining and healthy cuts.
Yes the best
Always learning something new.
Turn a shoulder to but against the jaws to stop the part migrating while taking a heavy cut.
That's a good tip 👌👍👏thank you
Use it all the time. Maybe I just take heavy cuts to often lol
Maybe my machines to small 😂😂😂
@@jasen963 lol it’s ok I have some small machines too
Ok, Great job... now we need to get started on the cam & crank... next vid :)
No cam work sorry
Just got a feed on your channel looks very promising!
Welcome aboard!
Cool tip!! Coolant needs to be on cut as blade gets hot so if before cut it will evaporate by the time it reaches the cut it will double your blade life
Thx
great seeing you today Kyle, best wishes from Orlando, FL...Paul
Hey Paul
Hey Kyle, I saw you on the Topper Machine channel looking at the machinist collection. Incredible!!!
Yeah I was there crazy
Great job brother 😊
Thanks ✌️
I like the way you were so cautious unravelling the bandsaw blade. I just toss mine in the air and let them unravel nice and violently and flail around the shop floor. 😀
I do that too
Love that surface finish. So much nicer than cast aluminum. Too bad no one will ever see it once it's installed. ;)
Yeah no one cares lol
is this blue lathe you used in the video and the one you restore clausing same or different. because i can see a huge difference in the paint shade.
Same it’s just dirty
good to see the good old Colchester doing some work
Indeed
A telescope gage and a snap gage are two different things.
The reason it matters is if you order one but need the other it won't work. They are not synonymous.
Ok I’ll probably still use them interchangeably
First operation Save the tip of the insert from chipping if your tool is not dead on center when you go all the way to the center of the material by first drilling the hole thru the part??
👍
Looks great. Saw you up with Topper this morning at that jeweler’s home shop. Are you eyeing anything up there?
Probably not most stuff is too small for me.
That blade unboxing was scary, next time throw it and run
Yeah I usually do did it slow for the camera
Very nice job!!
I am I spot make one for my truck
Thank you
Sounds good
Nice work. Good idea to make it out of steel this time, making it stronger. But I would still have made a larger radius in the corner of the boss, as this is where the part broke off originally.
Yeah true
@@VanoverMachineAndRepair I would second that sugestion of @zoltannagy, as an enginner, its always best, application permitting, to include a rounded shoulder at the base of the boss. Sharp chamges of direction of torsion will allways induce cracking over time. With a rounder shoulder, the stress has nowhere to concentrate.
I love your approch to your work, You never stop learing, ever :)
Just commenting for the algorithm
Much appreciated
18:45 Hi. Just off topic thing. That old part broke from 90 degree base. Should it use radius on that location, so it will be more durable ?
You changed to harder material already, so of course new part wont need that.
Technically yes but force is not to high. Did not break under operation. Broke because it was bashed w hammer
I don't think you mentioned temperature. On that big of a piece, you could be under or over specks just by what time of year it was. Very good job.
Yeah very true
8:40 You know what I find impressive!!?? .. A situation like this where material is removed with a Cut Off tool, and Trepanning Cut. This leaves us a suable steel doughnut of material, .. (basically free steel!) :)
Exactly!
I’m curious, why Premier offered you the opportunity to examine Russ Garens collection? As you are not in the same field of machining.
They did not. They offered it to Josh and I happen to be at Josh’s shop on the same day so I went over there on my way out of town.
@@VanoverMachineAndRepairI seen a sneaky cameo from you on topper channel. What a collection, you'll never forget that. Maybe $5M worth of the best precision tools anyone will ever see in one house. Incredible, you were very lucky👍👌🇦🇺
@@adhawk5632 indeed I was
4:49 You could have just let it rest against the back of the vice .. then cut out that existing bas saw gash .. saved some materia!!
Yeah
Which drawing software do you use? Thanks!
Fusion 360
@@VanoverMachineAndRepair Thanks!
That drill seemed to take a dive off to one side early on in the hole in the main bore. Might want to take a look. Good video anyway 😀
Yeah maybe was not critical in this application at all
LOOKING GOOD.
Thanks
😊My question is not why you turned down booth ends but why go through parting it off when you had to face it afterwards anyway. Why not just take it out and band saw it ,which is much easer to me and then face it back off.
Many ways to do it. Some days I am not feeling parting. Other days I am.
Great looking cut on the Hydmech - bimetal blade ? What TPI ? Many thanks
5 I think or 6
Would you sell the drawing?
What you need it lol I’ll give it to you
Where do you get those outsoles on your boots? The ones I get are junk.
He did a video on that exact topic👍👌🇦🇺
Yep
That micrometer costs more than the part your making lol 😂
It does that’s how the trade is
Was that you in Josh Topper"s latest video?
Yea
@@VanoverMachineAndRepair That had to be amazing to see all of that stuff.
@@scottzink3455 it was very cool
If I give a machinist a drawing with no tolerance values, is it assumed for him to get close enough that’s reasonably achievable? Or is there like a standard +- 5 thou?
Most shops have a standard if no tolerance is called based on how many digits are after the decimal. For example if you need the OD to be 4 in then it's can be assumed +- 0.1 but if you for the same OD there was 4.0 then the assumed tolerance could be +- 0.01
Some shops do follow a shop rule but there are no assumptions in machining. Anyone handing a drawing to a machinist should specify the tolerances. Most drawings do down below in the tolerance section. Even if the dimension is not written on the part the drawing specs what to do when no dimension is called. Most of the time when a customer brings in a part with no idea or drawing simply knowing the application and using common sense works 90 percent of the time.
Unless otherwise detailed your right. That's what numbers past the point are for haha@@dereksantiago6208
It more stronger to make that from steel
Yrp
Your friend Josh Topper has just shown this & I think that you will find items that you have been looking for for agers Have a look at it (he could well have contacted you already) Tour of a Hoarders Machine Shop - Complete Auction of the Estate of Russell Garens (RUclips)
I was there you’ll spot me in the back of a few shots
@@VanoverMachineAndRepairI thought that was you in the background. A lot of nice equipment in that shop, I wish I was closer.
Ever tried cleaning a machine
No never
@10:23 This is the worst drill i've ever seen in my life , and in all of youtube.
DO NOT DRILL LIKE THIS AGAIN
I will use it again just for you
