Aluminium TIG repair?

[Badger]

So I decided a bit ago to repair and possibly ride or sell an old PK Ripper frame I have had in storage for some 25 years. I know there are a bunch of bike nuts on here so I was hoping somebody might have an idea on how to go about fixing the break.

It's a classic upper seat post clamp break, right on the upper cross tube.

I was thinking of doing what they did on the second generation frames kind of.

Was thinking of making something that sleeved over the upper tube and rear Y in some way then weld it all down. So what do you guys think would be the best way? Is there anybody on here that would be willing to try....lol?

Are the top two pics not showing?

They are showing to me but they are just the attachments. They should be fixed now.

weld one on from another bike?

I can order a length of 6061 T-6 and replace the entire tube. I just don't know if that is easier and better. I don't know how good aluminum is with rewelding and how much it will take away from the strength. That is my major concern going that route. Also going that route I would want to make a quick frame jig to keep everything in place while replacing the tube. I was thinking of a piece to sleeve over the upper tube and rear Y to get away from those problems.
