The Side Stand Mounting Lug Snapped.

[Rocky]

This is not intended to nitpick or point fingers - just clarification.
This is a Triumph oil-in-frame. The very large oil holding frame tube ran from the headstock, under the gas tank and then down where a gauze filter was fitted on the bottom end. The filter was removed to drain the oil.
I'm 100% certain no oil was in any of the smaller frame tubes where the sidestand lug is attached.
Any welding there should be no problem.
I'm no "expert" and stand to be corrected

Rocky you're probably spot on, my memory is from something I read 20 years ago. In any case the welding should be done by someone that knows what they are doing.

100% agree with that

It’s like being human . At a certain age anything can happen down there so you’ve got bend over once in a while and check stuff. Could be rust ,could be toe fungus . Fortunately lots of experts available..

It’s the lug off the frame. The lug would be tack welded back to the frame and that might not be a good idea. Personally I would look at ways to reinforce the tube frame at that location when a new piece is welded on. It would definitely be a discussion to have with an experienced shop. As I noted earlier, would be nice to see the pictures of where this piece broke off in addition to seeing the lug separated from the kickstand.

Here's a picture of how it all goes together on my old '73 frame. Should be about the same.

So there is a reinforcement tube around the frame that the lug is welded to. This would have been important to see in the OP post as it gives us a better idea of the failure. Also might give a better idea on how to approach a repair.

I'm afraid I'll have to deduct 2 points (-2) for spelling. It's NUCLEAR!

And as a side note I'd like to point out that a nuclear chain reaction produces a lot of energy and visible light. (Don't believe me? Go stare at the sun for few minutes, you'll see the light from a nuclear chain reaction (just don't stare too long)). Also, and this might be a fine point, but there is a noticable delta between simple metalurgical fatigue failure and a nuclear detonation. My 2 pennies worth are up.

No, no, no . . . it's nukuler. Haven't you noticed how ninety-five percent of people who use that word instead of nuclear don't know (if you ask them) what a nukule is? Hence the ON PURPOSE joke. Gimme my two points back!
