Main gear cylinder rod was had only about 1/4 inch tread tapped. I did not think that was enough, so I tapped the hole as far as possible resulting in about 1 inch of thread. Took a couple of tries but I got the cable installed. Hooked up electrical part of hydraulic pump via Wayne Lanza setup (thank you Wayne). Gear retraction is pretty good. Emergency extention is good. Have to enlarge hook on overcenter linkage for easier breaking and unbreaking of overcenter linkage. Have to retension cables. Have to work on nose gear door closing as I don't think they are closing completely enough
