I've found that compounding makes for more power but less thirsty situation.

Perhaps if the 2nd cylinder was 12 mm bore and plumbed appropriately then it could be 180 out of phase for Woolf compounding.

On these engines they run best if the hot steam is allowed to build before starting off.


P.S. Tony did you get the binding chain issue resolved?
