[TR] progress on the gearbox!

[Jim Muller]

I'ver started putting things back together.  Got all 49 needle 
bearings in the layshaft, just kidding, there are 50.  Question, does 
anyone have a cut-down layshaft or similar wooden dowel that I could 
buy or borrow?

I'm looking at the brass synchro rings, wondering whether they are 
worn, how to measure them, etc.  Spitbits lists one part number, 4 
required, but the ones on the gearbox are visibly different even if 
nominally the same.  The three small protrusions (not the three big 
ones) on the 2nd gear ring are shorter than on, say, 3rd, and appear 
worn down.  Does this indicate replacement?  Not sure how they should 
be measured.  The 1st ring is much beefier overall.

Nothing else looks problematic at all, which I guess is good.

Tanks,
