Sad to here that Wod has passed away - I wondered how you'd got the K27 - it took him about 4 years to build, and I think he named it after his Dad.
You shouldn't need to change any other gears in the Connie - the drive axle is usually the culprit, and from what I've seen - all two of them - my money is on manufacture stress rather than use.
My old Connie had been used a bit, and the nylon gear looks just fine. The Connie that I recent;y bought second hand has had far less use - minimal wear on the drivers - and the gear had four splits at the hub, close to the axle, but they hadn't spread out to the rim - the point at which you'd expect it to fail.
Unlike me, it's not the teeth that fail, it seems that it's the bonding to the axle.
