Hi PD's -----just studying up a little in anticipation of/for my unfinished

feathering paddle set courtesy of e-bay... & am wondering :?:
1) Drawing "DRG No PW6A" - being full sized dimensions for "PS Waverley Year 1931" - End Elevation view provides a clear dimension of 1 1/4" eccentric height axis above that of the paddle wheel axis
2) "Drawing M9 - sh2" - "Accessories for a Diagonal Paddle Wheel Engine" by [the renound] Edgar T Westbury [not dated but assumed as late 50's] confirms that the eccentric axis height
AND the paddle wheel axis height are equal
.... @ 1:25 scale this 1 1/4" is only some [0.050" or 1.25 mm] so not sure what this is all about..... but assume it must be some mathmatical/geometry to further improve paddle blade entry.....to ..... exit.............etc
However I would be interested to listen to any comment offered - Derek
