SNNC 345 P1 Big Split Bronze Bearing . Monthly Give Away

[@papatomsgarage7611]

Very nice John, I never thought to solder the halfs together. Good to see Trev in the video, I watch him build that van.

[@mpetersen6]

This brings back memories. I've made I don't know how many split bronze bearings over the years. Mainly for old open frame stamping presses and the mounting bearings for large horizontal Cincinnati Broaches. We always roughed the ID and OD to a little over the slitting saw width and then silver soldered them together. Set them up in a 4 jaw with the seams as close to 45° from the jaws as possible. Semi-finished to about +.040 or .050 on the outside and wrapped with hose clamps. Finished the ID and then the OD. Smack with a deadblow to seperate and mount. Most often they were mounted with brass flathead screws. Then they invariably had to be scraped due to the clearance the boss wanted to start with. The fixture bearings were machined to about .002" clearance to start iirc. Press bearings were generally .001 per inch of diameter.

Impressive work tonight John, congratulations to Justin. Thanks for sharing.

[@MaturePatriot]

Congratulations Justin! Saw the bearing pictures on FB. It will last as long as the oil hole doesn't get filled with shite again. LOL That bearing is a thing of beauty. That lovely young lady at 17:30 reminds me of a girl I dated, 53 years ago, while in school.

[@jeff1176]

That's an impressive piece of bronze and very nice machine work on it. I'm not sure I understand why it was cut apart, then soft soldered back into one piece though.

[@tramtoby]

I remember them making these bearings when I used to work in the coke works, they made them exactly the same. Nice memories.

[@HaraldFinster]

Very impressive bearings. The material must cost a fortune. Nice video as always, John! @Toby: out of my interested in industrial history I am curious and dare to ask which coke works you have been working at. (I hope you don't mind me asking.) Best wishes from Aachen to beautiful England Harald

[@tramtoby]

@@HaraldFinster I worked at Cwm Coke Works in South Wales.

[@HaraldFinster]

@@tramtoby Thanks for your reply, Toby. That name brings back sweet memories, as I photographed the Welsh collieries in 1990 and visited Cwm Coke Works in 2003. It was a fascinating place. Hope you enjoy my photographs hfinster.de/StahlArt2/archive-Cwm-en.html It was a wonderful experience to meet the friendly and hard working miners and the management was extremely helpful too.

[@tramtoby]

@@HaraldFinster If it was still open I would still be working there. Best job I ever had.

[@bostedtap8399]

I used to do the turning pre and post soldering, as an apprentice, I was scared to death of them splitting, these were for Seam Welding (Electric Resistance)

[@Just1GuyMetalworks]

Now THAT'S a bronze bush! Funny you should mention how pricey it is. Just bought a 150mm x 35mm hollow bar, dude charged me $30 lol. Can't imagine the price of that 🤣. Probably the coolest little food truck I've seen, now I'm hungry. Thanks for sharing! Cheers 👍😊👍

[@EverettsWorkshop]

Never thought of soldering the halves together to machine them, that is an excellent idea. May be a very old idea, but excellent just the same!

[@chrisyboy666]

Yep C a Parsons been splitting bearings that way since 1898

[@montydog0]

Fascinating as usual John. All the best👍👍

[@daveticehurst4191]

John, to part the bearing, fire up your metal furnace and place it on top to heat up. This will be a more even heat than using a gas welding torch. Or if you have one a BBQ.

Great video 👍 Trev with the missus!

[@MakeItMetal]

Those cakes look amazing! good to see Rob and Sarah actually taking a day off! great video John, thanks :)

[@TheChristeepher]

Great video as usual John. Thanks Bonny Lad.

[@paulmorrey733]

Thanks John

[@59jm24]

Nice to see Trevors Wife's restored Bedford pastry truck ,

[@TrPrecisionMachining]

buen video..gracias por tu tiempo

[@Unrivaledanime]

That is one nice food truck

[@POMOC36]

I believe that the truck was restored by the guy standing there; look up Trev's Blog;' kzbin.info/door/B8HF8Pqug-Pc7DFqX9lf_g. John didn't mention it, but maybe he, (John), didn't realize Trev is quite the KZbinr; Nice work.

[@raymurphy9749]

Beautiful Bedford CA , looks in absolutely mint condition

Years ago I worked in garage where they used to repair car radiators they used town gas torches and the flux was Spirits of Salts. Will you replace the bearing if it fails in 80 years time instead of a Hundred?

[@TheKnacklersWorkshop]

As always an enjoyable video... thanks John...

[@paulp96275]

Fantastic job true craftsmanship stay safe 👨🏻‍🏭

[@raymurphy9749]

Beautiful Bedford CA there as well, absolutely mint condition

[@BensWorkshop]

I like the bearing consturction.

[@mealex303]

congrats Justin

[@carlwilson1772]

That was very interesting. Really enjoyed it. Couldn't understand why the piece wasn't bored to size then cut in half. There must be a reason. Very satisfying job to do in any case, knowing it will last another 100 years.

[@johnl5177]

because when you cut the bearing in half you would lose the thickness of the blade on each side therefore you would be losing your diameter or whenever it goes around the shaft you will have a gap at the place where the blade went through and it would cause the bearings to be able to shift back and forth

[@carlwilson1772]

@@johnl5177 Thanks for that, of course. Dont know why I didn't see that to begin with.

[@joshonthetube]

If I understand this process of soldering the halves together, then machining on a lathe correctly, it seems that it would allow you to avoid the need to line bore a 2-piece split bearing afterwards. In this situation, where there's just the half bearing shells, it seems to me that it could have been machined on the lathe in one piece, then cut, and it would have been ok? (this process is much cooler though, and it sounds like it's more authentic/correct)

[@VulcanBomberxm655]

Split bearings have to be bored and turned after splitting. Otherwise there will be a gap between the pieces, that means you'll clamp the shaft with them and it wont spin.

[@markmossinghoff8185]

@@VulcanBomberxm655 that's true if the two halves are used together, however these bearings will not be used as a set. Each half will be installed on one side of the machine by itself with no gap to account for.

[@bcbloc02]

joshonthetube I was thinking the same thing...

[@MrCelistaskin]

We made smaller versions in our shop. Always machined them, then cut them in half with splitting saw.

[@artnickel1664]

Nice motorcycle in introduction. Premier 1912 tt ?

[@FrontSideBus]

Basically a scaled up version of the soldering that we did with Bob!

[@malcolmtill]

Yaaaaay Tracey and Trevor.

[@jayreiter268]

Why not machine it before cutting as it was a tube and not individual castings as originally made.

[@RyanWeishalla]

Interesting way to do that.

[@desaivishal9485]

Which material uses joint both pcs

[@johnnyholland8765]

So many ways to do things. How much did the material cost in US dollars?

[@tattoos1988]

Cracking video John thanks for sharing mate well enjoyed it hope all is good with you and debs stay safe all the best mate

[@andrewgiles6192]

Its Trev!

[@MCEngineeringInc]

Neat process 👍🏻

[@raymurphy9749]

Excellent video John, just out of interest how much did the bronze stock cost?

[@eyuptony]

DIDN'T KNOW THAT John. No bearing on the bottom. Really interesting video 11/10. The best stuff always stings lol. Tony

[@paulatkinson2849]

Who is the new guy (bell end wrong size drill) lol

[@Vickwick58]

Perhaps I missed something, but why does there appear to be a US flag balled up on your work surface?

[@doubleboost]

It is an old tee shirt the bearing was wrapped up in

[@sandrammer]

@@doubleboost , thank goodness that isn't an American flag. Would have been a sad day to think you may have been a hater.
