Dear all,
I am building a solar heated gamma Stirling model, and I would like
to drive the pistons with a ross yoke : the problem is to calculate
the dimensions of the ross yoke drive having two different pistons'
strokes...
Is there anybody experienced who can give advices ?
thanks in advance !

Try laying out the drive at 4 or 5 times actual size. Make the horizontal distances on the linkage inversely proportional to the desired stroke(s). If cut out of poster board or card stock you can assemble with thumb tacks and test it to see how well that solves you problem.
