Correct on the timing sequence - centering travel first, then adjust the eccentric to open just after TDC (and close before BDC). Each side gets same adjustments, relative to its own ports/crank. It can be fiddly, tiny adjustments, or sometimes it just falls into place and runs!

When it closes will depend on the valve lap, if any - could be well before BDC.
Finally, I have a nice piece of wood coming, but my woodworking skills are not great. I'm going to have to cut a slot for the flywheel using a series of holes; luckily the base plate will cover any mistakes, so fingers crossed it will look ok!
