Minneapolis Crankshaft Follow-Up and Taper Turning on a Trailer Spindle
Вставка
- Опубліковано 8 чер 2024
- While I am unable to be there to repour the bearings on the Minneapolis, we did find it to be a 1/8 inch out of square. This was causing the angular travel of the connecting rod and the binding we saw.

New lights look great. Lighting is always a worthy shop upgrade.
Definitely!
More light is always good, especially for us older folks. 😊
Holy balls - I’m hust blown away by the mirror finish you get on these parts.
Lighting is definetly better. ( Brighter ) And it does show the peiece your working on better. 😀
I remember over 50 years ago in the secondary school metal shop making a four way pulley. Initial setup was with the cast aluminium blank in a four jaw chuck to face the large end and bore the hole through it. Then we had to make a tapered shaft to put the pulley blank on to machine for the belt. Turning the shaft involved offsetting the tailstock slightly to produce a very slight taper in order to have the pulley blank near the center of the shaft. The instructor came around from time to time and I had almost finished a pass. When I checked the pulley, it was too close to the tailstock, so I took another one thou cut as the instructor came back and was worried that I was taking too much off, but it ended up that the pulley was pretty close to center. That was an old Hercus metal lathe, which had none of the sophistication of newer (and older) lathes.
The new light are great. It’s funny, the older we get the more light we need 😎👍👍🇬🇧
Lighting to me is important and your new lighting is an improvement.
The best thing I ever did in my shop is changing from fluorescent lighting to LED.
I put in the same number of LED's as I had fluorescent and now its so bright that I have to turn off half the lights.
Only using the brightest over the machine I am working on at the time.
I enjoy watching your videos .
Shop looks definitely brighter Josh
The new lighting is a great improvement! It makes it a LOT easier to see what you are doing and vastly improves our viewing!
Josh, The new lights are great! Nice work on the axle stub !
the new lites are a major improvement !
New lights look great, much better.
New lights are great . . very good color from the lights. . NICE! ! !
New Lights Look Great!
New lighting is GREAT !
The new lighting looks awesome, good job
Someone sure made a mess with that Minneapolis crankshaft. It sure does sound like a cover-up for someone's original mistake, whatever that was, to cause the original damage. Hopefully you get it all sorted out correctly this time.
New lights are always a good upgrade.looks brighter in the shop
New lighting looks really great. It helps to brighten everything up so it’s easier to see.
The new lighting looks much better, but then you knew that already. In fact, a blind man would notice😂
The lighting is great Josh.
Nice job on the axle.👍👍
one of the few must watch in HD for max enjoyment, thanks for the regular fun times Josh
The lights are definitely nice. 💥
The new lighting is much better! I have started using a lot more light the older I get. My father used to say old eyes need more light. I now understand what he meant lol.
The new lights look good, another thing that may help with the lighting is to try a LED light strip over the top of the lathe at the centerline of it.
The lights are great, Josh. I'm sure it will make a difference at all your work stations. You know, I had old guys telling me about pouring bearings and I have seen the end product, but I've never seen it done. Looking forward to seeing how they come out. Thanks and have a great week.
Unfortunately an impatient club member already took it upon himself to do it.
😢
For videos showing Babbitt work, I suggest searching for either Keith Rucker or Keith Fenner and Babbitt.
Lighting is killer Josh !
New lights look great.
You mentioned going blind with the new lighting ..... It will in fact be the opposite with having better lighting being better for your eyes with no eye strain. The new lighting is definitely much better, we can see the difference. It's always good having good light with whatever you are doing. I set my small 100 square feet shop up with seven lights, so that I have a light on each bench or machine and one brighter in the middle of the room. My wood shop is a little smaller and has six lights. I'm using LED bulb lights, not strip lights.
Lighting all good. One can't have enough in your shop, especially over the machines to aid with setting up jobs. Cheers Ian
Thanks for keeping us in the loop Josh, and a little machining too! thanks and keep well buddy
New lighting looks great Josh!
Lights are fantastic
The lights are awesome
new lights are fantastic mate!
Lights look great
New lighting for sure! Ric
👍😎👍
.
New lights look good ..
The lightening certainly looks brighter. As long as you can see alright to make a living the main issue..
Lighting is a big improvement!
Lighting looks great. Cheers
The lighting looks good.
New lighting. Looks good.
Love the lighting!
Love the new light's
Lightning looks great Josh, it really brightens the scenes up a lot more allowing us to see everything much more clearly. 👍👍
There is almost NEVER enough light as far as I know.... Love the new lights Josh!
Great lighting!! I'm looking to upgrade mine as well. Happy machining!
New lighting much better.
The lighting looks way better . Same lights i have in my shop. Theyve been in there 6 years without a single issue
A cheat for axle issues like that is to use a bigger radius at the shoulder. Then you can use a washer with a bigger id to clear the shoulder but the proper width so the bearing doesn't hang up on the radius. I fixed a big grain cart that way years ago that use to break spindles every year it probably has been 20 years since no issues.
Lighting's great Josh, a touch 'cold' for our viewing but as working light perfect :-).
I wondered if I should have a few warm lights also.
Ho Josh, I have watched you for ages and never had an issue with your lighting, though I must admit that the new lighting is definitely an improvement.
Glad it helps.
Looking great and a big thumbs up 👍.
Thanks for the before, and after the comparison is a lot brighter, crispy,no shadows. Now we have the LIGHTS, CAMERA, ACTION 😊. From your mouth to gods ears, we would love to know what happen with that machine.ghost in the machine 😅
It’s nice to see Your methods to find out wether a part is in spec or not.
I think it would be interesting to see if the crank pin still measure right if controlled when crank shaft is rotated 3x 90 degrees.
Just so You don’t by chance measured in the one position where all seemed right!
Always interesting contents in Your videos!
Thanks PeO
I don't think rotating will change what I found. It was true and inline with the crankshaft. Turning it should not change that.
lighting looks great. 👍
You have a great shop. I’m jealous.
Thanks 👍
Jup, light´s good. Monkey like shiney. I have cluttered up my workspace with lights, too. One 112w neon light above, three lights on the workbench and an led light that I can move around. And a few light bulbs here and there... When I started lighting was awful. Now I´m okay, too.
That 1144 sure machines nice......new lighting is fantastic....I'll assume its all LED.
New lighting is a big improvement.
New lighting is always a plus ➕
Never worked in a shop that had too much lighting. Light is your friend! Enjoy the new lights.
NEW LIGHTS all the way!!!!!
On the lighting, Looks good, works fine, should last a long time. Your videos are going to be a lot better with the better lighting. You get 2 "atta boys". KOKO!
new lighting looks good to me.
Love the lighting. Almost looked like you were outside on a sunny day.
Added lights are excellent. Might consider adding a work light to the carriage or near the headstock for added lighting.
Possible reasons why the trailer spindle is failing, if there is a sharp transition at the shoulder where the bearing sits, that sharp transition becomes a stress riser that grows into a crack then propagates until the part fails. This is a cyclic failure or repeated loading/unloading over many, many, many cycles before the part fails. Cure for this is to put a large a radius as the bearing (bearing IDs have a radius to accommodate the shoulder radius) will tolerate at that shoulder transition and make sure the radius transitions are smooth.
1144 "stress proof" steel is a good material choice for this spindle.
Definitely not dark like a dungeon. Looks great.
As for lighting, next thing you will be wearing sunglasses. But for us viewers, excellent.
I was thinking that same thing.
The lights looks great. Turning the trailer spindle was interesting and I hope you get to the bottom of what happened with the steam engine
gotta love Badger Northland manure spreader, I did a show for them here in Orlando Florida in 1976-77
at the time, I had no idea what a manure spreader even was.....they had all the equipment down here
and had a big field at the Hyatt they did demos on....
Josh, Thanks for the update on the 25 hp crank....ironically, I just watched a Fenner rabbit bearing pour video 2 days ago...
looking forward to how you repair, cheers from Florida, Paul
Unfortunately an impatient club member already poured the bearings. I hope it is right.
@@TopperMachineLLC...Could the "impatient club member" possibly have been involved with the first problem....hoping to correct a mistake?
@@arkansas1336 fortunately no. This was done at another club in Rolag, MN
Thank you Josh!
New lights good.
Love the new brighter lighting. Someone did the repair wrong and was highly embarrassed. Thus the coverup. There’s a part two to this story however. Now we get to see it done right in Josh’s shop, “the second time”
Unfortunately an impatient club member already took it upon himself to do it.
Love the new lights.
lighting looks great!!
lighting looks really nice!!!!
Wow that lighting is amazing 😊😊
Lighting is sweet!
Lighting is perfect, great video ,
keep up the good work 😊
The new lights look great Josh!
It looks so much better under the new lights Josh. I put new LED lighting in my workshop/garage to replace the old twin double 58W strip light fittings. The new LED's are 70W and at least half as bright again, with daylight colour rendering. They have been up for about 18 months and everytime I go in I think those lights look fantastic.
Congrats on the new lightning!
Lighting is much improved thank you and keep up the great content!
Good lighting
The new Lighting is great improvement!
Lights definitely better 👍👍👍👍
New lights look very good 🇦🇺
New lights are great!
The new lighting looks good. Cameras are known for not capturing the lighting the same way we see it with our own eyes. The whiter color of the lights can help make things easier to see as you work on them.
Josh, i just installed some LED panels in a simular shop. I would recommend LED panels, because you get more light, you don't brighten up the ceiling, the hole light comes down to where you need it. The light distribution is far better and and you get less shading.
You get different sizes, i used 120x30cm (about 3ft by 1ft) with 40W. Colour should be 4000K and for filming i recommend a good CRI of more than 80, 90+ is ideal.
Greets from Liechtenstein
I already bought these and am happy. Didn't think about panels. I'm adding them to the high bay around the walls and it's made a huge difference. Couldn't be happier.
@@TopperMachineLLC well it's far better than it was before👍
I also work with highbay LED, great efficiency and lots of lumen. Next project is with 0-10V dimmable highbay. After that i have a retrofit for a large garage with LED tubes, i always eliminate the old tube driver and go for direct mains.
Big improvement on the lights another enjoyable job
it looks very good with the new lights
looks brighter and clearer
Looking good. I can see your work better
The new lights looks good. Bright lights are better to see what going on.
Of course, much better with the new lightning!
Lighting brighter, and makes things clearer. I hope someone will let you know what happened, sadly, the truth is that you may never find out. I trust though that with your skills, it will be as good as new or better when you are done.
I'm sure nobody will come forward. There is a lot of secrecy around what happened and why the owner was asked to leave Rolag
Add the plot thickens😊 will you be involved in finding and taking care of the problem? That would be some cool footage.
@@anthonyrivers8395 unfortunately an impatient club member already took it upon himself to do it.
Almost 100k subs. Congrats in advance.😊
Thank you so much 😀
@@TopperMachineLLC You deserve it. 100k doing only honest work filmed is exceptional.
