Aye, Aye. I already drew a diagram to scale and
made a paper pressing of he ports. Now that the shoe
is loose we can review the port/shoe arrangement to
determine if any adjustments to the ports or shoe are
needed. Photos and specs soon.
More pressing....the rod that drives the shoe is steel
and must have been left wet for an eternity leading to
corrosion of the threads that held the keeper-nut.
The keeper nut is a ground down nut, so that is BS too.
It all still works but I think the lifetime for running is
low. I am making plans for a possible replacement
P.S. The eccentric throw is 1/8". Paltry if you ask me
Thanks for the advice and the time you took to give it,
Wayne
