Because I didn’t have any tube. The time I’d spend ringing around suppliers finding the right size and someone who’d sell me 950mm instead of a full length. My time was better spent reusing the old.

Another great video. I love your techniques using just basic equipment. But at the end of the day you got the job done.

I am 57 and still learning the "best way" to tackel jobs!I think your approach was spot on, use the tools already out and set up, then switch if it's not going well. Great video, love the shirts.

I love how your danger-wand has the primary flame, but then it also has fun little secondary flames too! 😅

Good repair, spot on welding on larger diameter, though if I may comment, larger root radi on shaft, and polishing to reduce likely initiation of cracks. Great video and photography, thanks for sharing. Best regards from the Black Country. John

Do it once and do it right. It’s what makes you a professional. Thank for the video.

Good video, thank You. One minor thing that might be worth mentioning. When a shaft likes to snap off like that it is because it first developes a crack and then snaps off. Cracks like to start from sharp corners. From what I saw, You just created a sharp corner at exactly the place where the shaft likes to snap. Since You were already at the lathe it would not have been too difficult to create a radius instead of the sharp shoulder there is now,

Nicely done as always, Oliver buddy, good honest repair, I used to work in quarry maintenance and we did tons of these, Oddly enough I actually worked in a conveyor factory at one time too 😀

Top work again mate, I’m a fitter in a similar industry down south. When our machine shop makes rollers they always put a small hole somewhere to relieve any pressure during welding. It may save you a swollen piece of tube 👍👍

I like the logos. Look pretty good. Your filming and editing are spot-on. Thanks

Good video mate, a well thought out repair. That’s called a tail drum, and a head drum would have rubber lagging on it. A few things I’ll suggest if you’re ever doing a job like this again, drill and tap the ends of the shaft because you can screw in a lifting eye to help pull the drum through the conveyor belt when fitting. And always machine the shaft down to the desired size for a sweat fit for bearings, if the bearings just slide on they’ll not last as long (depending on the environment of course) I do maintenance on a quarry and work around conveyors all the time

They’re some good suggestions. Thanks! This is used for something to do with potatoes (not quite sure what) so it shouldn’t have as hard a life as in a quarry.

@bobhudson6659

Another suggestion. If you have the space and can adjust the ends to suit, on next job put a smooth radius on the transition where the 32mm is machined down to 25mm. As it is the sharp transition is an opportunity for shaft to crack again at this stress riser. As you have mentioned in answer to Peter's comment, this is used for something to do with potatoes. May not be as hard an environment as quarry, but as you are an engineer (I am not) you would be aware that cracking only occurs with flexing from load or where part is subject to vibrations which are long term and close to the natural resonant frequency of the item. Very difficult and expensive (meaning waste of time) to measure for those frequencies but radius will at least mitigate any crack starting. Retired mechanic/machinist in Land Down Under.

Good job going to thicker shaft, trick we found some years ago was to weld the end plates on the shaft on the inside only then weld into the rollers. No welds on the outside more applicable when welding stub shafts in the ends of tube rollers.

@leehotspur9679

The best way to do it ,the end plate supports the shaft weldment and stops the flexing stress on the weld itself Thicker the end plate the better as it acts as a hub giving support to the shaft

I’ve made these with a continuous shaft as well but with taper lock bushings at each end. Makes it serviceable. One I even repurposed sprockets that had the taper bushings already (turned down on lathe to fit inside tube, cut teeth off obviously…).

Great video, and I'm not questioning whether you should have built one from scratch. You're the professional, not me!

Good job, no need to complicate things. The original cracked shaft looked like a shock loading fault, I've seen a few of those years ago with the NCB equipment. Nice clean repair, shirts look good. Be safe keep well 👍

Very similar roller to what is found in brunswick bowling machines. I used to have to repair similar jobs where the bearings ceased and ate shaft down to a few millimetres. I ended up making through shafts

Add taper lock bushings to the end plates. Then they can repair in house.

A lot of work just to save that piece of tubing. Making all new from scratch may well have been faster, which means cheaper. If the roller is crowned, then saving it would be the better choice.

@snowballengineering

Жыл бұрын

Not really. If I had the material for a new tube in stock then yes. But by the time I’d spent finding a supplier to supply me with the right size tube that didn’t want to sell me a full 7.5meter length that I’d have no other use for. The less than an hour spent saving the old tube was definitely worth it.

Nice I like it👍

Nice dual-flame gas axe you've got there ;)

Precision fit!

Shaft diameter was not the problem. The weld was the problem. It must be the entire circumference instead of two partial welds. I don't know what the application is but the lack of a radius on any shoulder cut into the shaft tends to kick the problem on down the road. I'm sure it will last a very long time. Radius on all cuts is a good practice to maintain.

I've repaired several of them, but that it by bore out a broken part by 10-20mm. Then removed rest. Use existing holes and fit new shaft. Then just centralise and weld. At my work I don't have a lot of time to repair parts , production is waiting so I'm utilising as most as possible old parts and use minimal effort and parts to repair. Good movie... to much work. That shaft will snap again if setup incorrectly on c/v.

@snowballengineering

If I had a big enough lathe I could of removed old shaft and replaced with bigger. However the old ends weren’t welded in particularly well so I think welding in new ends was my best option. Thanks for your opinion. 👍🏻

Good repair

Don't know if the pin goes all the way through, at the beginning of the video... but the welds aren't that great on the whole of the part. Proper preheat/blanket cooling should solve some of the issues with the thing I would imagine. But, turd welds, typically means, they didn't do proper welding protocols to ensure the parts weren't compromised when reassembling the previous repair.

I think a new piece of pipe would have been the go! after labour and consumables?

Would have the stub shafts have been stronger if you had turned the small are down and left a radius in the corner where the bar went back to full diameter. A shaft will most ofter snap if you have a square shoulder where a small diameter goes to a larger on. Also keep the weld only on the larger diameter of the stub shaft.

Ironically the cheapest part ended up being the only remaining part left. You could have maybe just replaced the shaft by air arc gouging out the shaft welds but at least your repair is better than the original 👍🏻

Would it not have been best to use a "radius" to transition from the smaller portion of the shaft to the larger?

@snowballengineering

Жыл бұрын

Yes, but I didn’t have an appropriate tool. And I thought it’s survived this long with just a welded in shaft so it should last the rest of the machine’s lifetime as is.

I wish I had a Blunt that long, but no, alas it's all good.

Good morning. Well, a couple of things. 1) I'm surprised, given the known previous fatigue point, that you didn't (appear to) put a small radius where you turned down to 25mm. I realise that the new situation doesn't weld right up to the plate, but it wouldn't have hurt. PLUS, it's generally good practice. 2) The printing on both shirts is too big; especially the darker shirt. Personally, I would like maybe half that size. On the lighter grey shirt, the 3 logos at the bottom could be quite a bit smaller, (50%), and given that it's the back of the hoodie, the main logo could be a bit (~25%) smaller. Well, you asked.

Hi Mark I was thinking the same after watching the video. If it wouldn’t interfere or obstruct say a pulley or bearing block I would have left a 1/4" radius to reduce any future stress or fatigue points. But he did a good job overall.

Yes, a radius would of been better but with the limited tooling I have at the moment I didn’t have one suitable. And I thought with the original roller lasting as long as it has with just a welded in shaft, it would be alright without.

Not sure if the bigger shaft is going to be stronger without putting a radius on the transition. Although the weld might have caused the failure in the first shaft

Could you have welded the shaft on the inside first and then pushed it through the tube so you have weld both sides.
