Thanks for the responses so far.
First, let me say- this is not the only thing I'm doing this summer, and I'm spending plenty of time with the opposite sex. Jeepers, folks. But thanks for the advice about not repainting. If I did do it, it would be the absolute last thing I did, so we'll see if I have time. I'm kinda an artsy fartsy type, so the idea of painting it just appealed to me. But as the paint is basically in perfect condition, I'll think long and hard before starting that.
Jeffiah- I might just steal your idea, once the trike is finished. I'll give you some royalties if the book does well. Where's Tierra del Fuego, by the way?
The speedometer is way cool, but definitely broken. I haven't really looked into it much, so I don't know what's wrong or how to fix it. Sirrius Rider- thanks for the notes on the speedometers. I might just have to invest in one of them new-fangled digital ones if it looks to hard for my tastes.
I'm keeping the seat on the trike. It's way comfy.
I agree with all who said keep it a 3-speed. The problem I see so far is that... well, the shifter doesn't work! And I don't know enough about that transmission thing to really know what's going wrong (Bill Kapaun, you seem to know what's up with those- any thoughts?). The little switch is stuck all the way up on the control- I think you can see it on the picture I posted. The metal switch is supposed to be down where the numbers are. I can still pedal it around fine, but the switch won't budge. Hmm :/
Tomorrow's task: I'll be trying to take apart the trike, and investigating and cleaning the transmission hub. Wish me luck, I'll post when I'm done working for the day.
Thanks again all. This is to be a great summer
