Back in business!
With a little heat and careful wailing I got a scratch section of seat post lodged in behind the mid tube junction.
I’m feeling good about the strength of the reinforcement. Each joint will have about 2 inches of support above and below it from the internal tube.
The short, functional
seat post just meets the jammed support at it’s lowest position, very close to where I’ll need it, so I think this worked out about as well as it could have.
