Re: Willow
I think its time to get you guys up to date.
The seat arrived and I didn't like it. Mostly the way it looked on the bike. Kicked around different seat ideas (even tank ideas) but wasn't feeling any of it. I came to the conclusion that the backbone was throwing it all off. No matter what I did it looked long and dragracerish. Time to change directions!
To get her back on track she needed more flow, more fluid like lines or maybe even to be a little organic if you will.
Bent some conduit and played with lines
The two pieces of Conduit are close to what they would be. The way it is with the arc above the tank would allow the tank to be a bit flatter towards the front and roll off in the back. I could make it arc more in the front but that would really affect the tank shape. Plan is to keep the line somewhat low.
New back bone:
The very cool part of this is I've been able to bend all the tubing in my pipe bender. It took some work but well worth it. I'm quite pleased with how the bends turned out.
First I ground the die for the bender to an exact fit. Pipe is measured ID and tubing is OD. The dies are a little small for tubing. I used the same technique to do the small tubing on teh bottom rails. Anyhow, Laid the tubing on my wood stove and got it warm. I tried a few bends first and got nice results. I was considering filling the tubing with sand but it really wasn't necessary. Anyhow, this is what I got: 1.5" dom 120 wall slugged and ready to be welded up.
After a bunch of bracing, and cutting away the old back bone got it tacked in. I decided to leave the motor in to help as a jig. The top motor mount was flipped forward and welded to the down tube. The braces welded from the bottom tube to the steer tube. Cut out the old backbone I had extra shit welded all over this thing haha
cut some cardboard for tank shape
This is where she is at today:
bent a piece for the rear vertical support (at the coils mount) and also made the lower cross piece where it attaches to the bottom rails Its a pretty subtle detail because its kinda hidden, but its a nice touch(thanks Doug, good call). Also cut off the kick stand. It hung below the rear arched bottom rails. It will get moved forward.
Plan for the tank to be made from scratch. Going to use 16g sheet metal. From above it will match the radius on the sides which is the same as the backbone. Going to be pretty narrow and taper off at the rear. I'm still working on figuring out the electronics and wiring. Think I'll run a capacitor. Also plan to weld eye bolts to the frame to hold any exposed wires. The tail light is getting tucked above the upper rail real nice and tight to the tire. I'm thinking about using an old cadillac light. The license plate will have a reverse radius. Anyhow...
Its still only tacked together but I was able to cut off all the bracing and roll her off the table.
I put the chain, coils, and the carbs back on for a peak. I still have a but load to do, but here she is:
