Well, a quick 15 mile test run this morning and everything appears to be working on the almost complete rig. The shifting is still via manual derailing but the low range is supper on big hills, the ones I avoided before. I will be working on the handle bar shifting system next, should be great fun. The 16 tooth output sprocket is a super cruse ratio and allows me to handle most hills, the 13 tooth is supper low with great torque. I switched to 410H and 3/32 track sprockets on the output to aid derailing. The picture is with the side cover removed.
