Thank you so much for your kind comments, Gnomey and A4K!
Yes, Wayne, that was a seat adjustment lever as you clearly imagined and I'm ready to install the seat now
It has taken time for me to adjust the measurements of those gears as original drawing in a book was rough.
This time, I am paying more attention to the dimensional accuracies than ever.
Thanks.
I agree Shinpachi, keep up the great work. This endeavor is going to be very rewarding at completion. I can imagine the hours you put into this work. Simply am amazing.
