TCR1 J.low edition

With a way wider rear end - almost as wide as the Scion XB!!

I kind of goofed with my rear mod calculations. I figured 44 inches would be worth a try, but I forgot to allow for the width of the hubs. So I cut a piece of rect tubing at 44" and welded on two new flanges. After the wheels were bolted on, I realized that my width expanded to 48.75 inches! Probably overkill. Oh well - I'll take this puppy out and give it a good test to see where it starts to tip. My feeling is that it would slide before it ever tipped - which is good, but I think the width would make it difficult to manage on shoulders and with traffic. But you know, if I added a flashing yellow light to the back - or a strobe (even better), and simply took the entire lane (on a shoulderless road) I bet I would encounter less problems with traffic than I currently do trying to stay as far to the right as I can. People never seem to mind waiting behind a slow moving piece of farm equipment until it is safe to pass in the oncoming lane - but to wait behind a bicycle! Never!! Lay on the horn!!! However, if I had a flashing light on the back - especially when the fairing is on, then I think traffic tends to be interested in what is going on. What the heck is that? - wow, neat. Or - what the heck is that? Oh - it's that crazy neighbor again.

The Scion is the newest vehicular member to our family. I got it as a surprise for Helen - late anniversary present. Since they aren't available in Canada and Toyota has no plans on selling them in Canada for a few years, I thought it was a great opportunity to have something unique for a few years. It turns a lot of heads, it's fun to drive and GREAT on fuel!!!

My old friend and shop-helper Angel Basilis, TCR1 J.low, and the cosmic green Scion XB.

I'm also going to experiment with adding some camber to the rear wheels and run a watts test to quantify exactly how much efficiency is lost to the higher rolling resistance. I'll probably add the camber to the old track width.


2 Duu LIST:

1. Buy and install right brake (FINALLY ordered it!)
2. Invent new cable tensioner to allow more steering bar turn radius
3. Add front derailleur
4. Order 20mm axle bolts for the rear wheels (I'm using 1/2 inch now which isn't right)
5. Design and machine 2 seat mounts out of aluminum to replace current steel ones (e-machineshop.com) LATER.
6. Design and machine 2 steering tensioners out of alum to replace LATER
7. Order a new front wheel! (Helen is kind of upset that I am user her Zipp race wheel!)
8. Start work on the first fairing (starting now)
9. Invent steering stiffener
10. Add larger chain ring and modify chain stays
11. Make clamp-on out riggers and try to flip it (changed to#25)
12. Fabricate new steering bar (aluminum or composite?) or rework existing
13. Lathe an aluminum collar for .5" hub axles (Ben E. said he'd do it for me) (That didn't work - James is doing it for me now).
14. Design and build a trainer to fit mag trainer (donated by Michael Hoenig).
15. Replace steel cables with Kevlar (maybe not - I think the flex of steel is good....)
16. Crotch guard / fender
17. Narrow chain stays to allow foot to clear
18. fix derailleur
19. crank hitting chain stay
20. chain stay frame flex?
21. Narrow, high density foam for seat
22. Make front quick release safety
23. Change steer cable sheaves to Pete Heals idea
24. Add missing and new webs
25. Add a g-meter and quantify turning g's at flippage threshold. (add outriggers)
26. Widden the track width to 42 inches and test.
27. Solve the rear stiffness issue (If the wider track is good, then build a whole new rear triangle)

TOTAL distance on TCR1
