Stephenson valve gear: where to start?

Post by Scrat » Sun Apr 13, 2014 11:42 am

Hi,

my LBSC Minx needs to have the valve gear set. It ran fine until one strap broke and hit a sleeper. This seems to have moved one of the eccentrics.
Which is the best way to re-adjust the valve gear?

Some sources like this one start with the eccentrics:
http://www.steamingpriest.com/links/pro ... alve-gear/" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;

Others start with the rod and set the eccentrics later:
http://www.sdrm.org/faqs/boilers/page85.html" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;

Where would you start?

DONE. Tried the "eccentrics first" approach and now it runs.

Best regards

Holger
