Thanks for shedding light on the exact problem — you're right, it's the centre tube, not the cannon pinion. That was the issue, and after tightening the centre tube, everything now sits correctly. The train bridge can be fully tightened and all the wheels run freely. I haven’t tested the pallet fork yet as I haven’t refitted it, but I’ll be doing that shortly to confirm if the issue is entirely resolved. @Neverenoughwatches Sorry for misusing the term earlier. -
If the existing spring is 0.06 then it's been replaced at some time in the past and would potentially be too weak for this movement. -
A quick addition: Given when I measured the springs I got 1.5 x 0.06 I thought I'd figure out how long they are. I was able to do this from a photograph taken immediately above. The program Inkscape has a nice extension that allows measuring the length of a beizer curve, so I drew one along the length of the spring. It's 220mm. And 1.5 x 0.06x 220 x 7.0 does appear in the catalogue. It would also explain the lower amplitude I'm seeing. Doesn't immediately solve anything, but the information is nice. -
That's because it's not a cannon pinion and just a centre tube. If this was the fault I still wouldn't have expected it to run without the balance. Edit @TimepieceTinkerer To clarify. Did you test the train ran smoothly with everything tightened down before fitted the fork and balance?

You're absolutely right — normally, a missing or even removed cannon pinion wouldn't stop the train from running or the movement from ticking. Just to clarify: the part I’m referring to isn’t the removable cannon pinion on the center wheel — it’s the fixed pinion that’s pressed into the mainplate underneath, which drives the motion works. I may have misused the term earlier. That pinion was loose in my case, and it caused the fourth wheel to sit out of alignment, which jammed the train when the bridge was fully tightened. Once I tightened that fixed pinion with the staking set, everything seated correctly and the issue was resolved. Appreciate your input — and thanks for helping me describe it more accurately.
