One is the brake torque rod. Very trick.
Don’t think so. It’s this pic I’m referring to (remote stop light switch perhaps):

Yes ............,, but ordinary brazing is at lower temperatures to SIF SIF bronze welded parts.
Brazing is NOT recommended for stressed parts like the frame joints, don't ask me how I know.
One of the keys to Triumph frames not cracking is the fact that they are brazed - at least the ones made by Triumph and not BSA. The BSA oil-in-frame frames to crack and they are some sort of arc welded.

Thank you.

My "talents" are only a result of trying to build stuff, getting in way over my head, and trying to figure a way out. We can all do that!

That's exactly what I do too, just haven't advanced to your level.
Mind you I'm still better than many. :)

And better than I used to be.

Are you sure you don't mean SIF bronze welded?
If I see a motorcycle frame just "brazed " I'll walk away!

I have no clue what metal they used. AFAIK it's called hearth brazing regardless of the rod used, but I am no expert. I know that when I blast a frame it looks like the same metal as the rods I get at Home Depot for the little bit of "brazing" I do.

Triumph had several factory tour "movies". This is the only one I can find today and it's only the first half. Please watch and once you know what they used let us lay people know so we don't use the wrong term.

Is that aluminum plate bolted to the swing arm pivot?
Did it require a custom longer pivot shaft?
Yes. The spot my feet wanted to be was right over the tube, so I built that bridge piece that spanned those three holes/mounts. There's a nut on the axle, under the bridge piece in addition to the nylock nut on the outside.

The swingarm pivots on tapered roller bearings and I made the swingarm and hardware, so the pivot axle itself was an easy project in comparison. There was not a lot of stock Norton or Triumph hardware on this bike.

Thanks, it looks good, looking for ideas for mine.

Thanks. This is the second set I built, with the first having more holes for adjustment, and much less finished. Getting everything in it proper place and functioning, being the job of the first version and then worrying about how it looks for the second.

The shift-side is much harder to get right with the linkages and kick starter having to pass through the same spot.

Couple more pics and problems. Always gotta stay on your toes.

The weld split on the bottom of the oil tank.

Not particularly happy with Tab2's oil tank. Three major problems with it, all have been issues with workmanship. This seam had been ground too deeply. Oh well. Rewelded and reground.

After six years the Brembo master cylinder for the front brake gave up the ghost as well. Couldn't figure out if it was the piston seal, or the seal to the remote reservoir as it was all an oily mess. Replaced it with the coffin style for fewer seals to go off.

I think I liked the remote reservoir's aesthetic better, but I don't think they were designed to withstand the vibrations. Went through a few mounts over the years. Oh well. A couple mini projects to fit this master cylinder, like the little half shim for clearance.

The motor's still running very well after a couple thousand miles from the 750cc rebuild this summer.

And the the bike is running very well in general. Very pleased every time I ride it.

Seems like a short list of problems for a build like that. Nice work. And a lovely looking bike.

Thanks.

It could be much worse. I got a solid 3 years of pretty much only tires and oil before the cases cracked, but the first solid year was chasing problems, big and small, some self-inflicted. Hoping I get another 3 trouble-free years coming up, but this 750 kit is pretty fun to wring out, so probably not. It's cutting into my 88SS budget and time!

Which 750 kit is it BTW?
Aerco. If you remember, there were definitely some issues with it. Off center boring of all the holes in the casting, so there was definitely a bit of massage work. The vendor, The Bonneville Shop, was not helpful in the slightest, but John Healy offered good advice and talked me down from the ledge. All the bores were perpendicular to the deck and the impossible to fix stuff was ok, so I went with it. As usual, it helps to have a fabrication shop in your back pocket.
