SNNC 345 P1 Big Split Bronze Bearing . Monthly Give Away 

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

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

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

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.

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!

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.

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 👍😊👍

Fascinating as usual John. All the best👍👍

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.

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.

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

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?

Great video as usual John. Thanks Bonny Lad.

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

Great video 👍 Trev with the missus!

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

I like the bearing consturction.

That is one nice food truck

Thanks John

Beautiful Bedford CA there as well, absolutely mint condition

buen video..gracias por tu tiempo

Fantastic job true craftsmanship stay safe 👨🏻‍🏭

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.

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

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

Nice motorcycle in introduction. Premier 1912 tt ?

congrats Justin

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

Yaaaaay Tracey and Trevor.

Interesting way to do that.

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

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)

Why not machine it before cutting as it was a tube and not individual castings as originally made.

Which material uses joint both pcs

Neat process 👍🏻

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

Its Trev!

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

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