Very nice choice Tel, I hope to enjoy with your progress so much as the last twin cyllinder engine. I like how you build this engine. Please could you put any sketch with the measures? I know that is a boring job, but could you add some element of mesure known as a reference in yours pics. Thanks Tel I enjoy a lot of with your engines, you built them so "easy". My apologies with me English as you know I am from Spain and languages are our unresolved matters.
