wheeee! bike is rideable! (sorta anyways)

Bike's looking good! Here are more pictures:





idler at the back.



A new set of handlebars for me. Actually an old U-bar bike lock which we don't have the keys for. It works. Enough to ride with, anyways.



idler for the front fork and head tube. The chain drags a lot because of its length.



idler for the underside of the seat. otherwise the tension of the chain causes it to drag on the seat. I have a lot of idlers.... *needs to do something about it* ...

And now... what you've all been waiting for... ME RIDING MY BICYCLE!!!!!



:-)


Sooooo much left to do though.....

attach studs for brakes, shifters for rear derailleur, better handlebars, attachment for back of seat, paint job, and more....

eeeeeeeep......

much props for the handlebars. Actually, the whole deal is pretty dang hot. I'm way impressed. One of my friends just made a set of handlebars for a recumbent he built up, I'll have to get pictures and post them. He took like flat mountain bike handlebars and cut them pretty narrow, then took a pair of cheap mounain stems and clamped them to the end of the bars (he eventually had to weld them on there because they didn't clamp well enough). He took the steer tubes and one leg from two forks, bolted the stems into the steer tubes, and welded grip areas onto the the ends of the remaining fork legs. It's kinda hard to picture from words, but they're way awesome. mayhaps later I'll try to draw pictures and post them or something.
sounds fun :-) i don't have enough time to build a set of custom handlebars, although i'd love to, so instead i'm going to purchase a pair tomorrow.
Bandwidth exceeded for the pictures. :( And I'm durn curious too.

I see you as a brave and adventurous soul to build your own. Looking forward to completion.
(damn you, ripway!!!)

give it 24 hours and it'll be back up.
So awesome! It works well, then? ^_^
Nope. But it will once I whip it into shape.
That's freakin' awesome! ^^
Very cool. That is definitely a lay-back seating position, geeesh. Almost the position you'd have on a low racer.

Regarding the idler locations, you might take a look at the Lightning bikes. Their chainline is just a bit shorter than yours, but gets by with two idlers. One beside the head tube to support the bottom chain, and one below the seat, to redirect the top chain. Look at mounting the idler on (or near) the clamp assembly for the seat, then directing the chain to the bottom of the idler instead of the top.

hmmmmm..... that looks like it could work. My only concern is that it looks like an awfully long length of chain between the bottom idler and the rear derailleur...when i've been riding my bike around it's felt like there's a ton of play with the chain and it's just swinging all over the place. Maybe if I tighten up my chain a little bit....

something to think on. thanks!
I don't really notice my chain at all on my Lightning (same frame as in that linked pic). Maybe a bit when I'm coasting over really rough roads, but that's fairly seldom.

Tighten up the chain so that it JUST shifts into the big-big combo (stretching the der all the way forward). That should do it fine.
It's a bent--you're not going to be able to do without a long chainlength, so you should probably resign yourself to it. :) My Giro has one idler that the top and bottom lengths of chain both use, and it works well now that they're making the idler out of something that will actually stand up to the chain. Last spring, about a mile from home after a week-long stint on the Katy trail, my chain chewed my idler in half, and I had to walk the bike in. All I could think was, "Oh, I'm so glad this didn't happen five days ago."
