Here's what I did today: Hit the gym, levers! I'm putting you on a DIET! Cut the levers down to a more manageable shape. Other than final shaping and sorting the pedals/pegs, the right side is done. Works perfect! The left side is still pretty rough. I'm prototyping at this point. The shifter clamp needs to be remade in steel. It stripped out, and the clamp broke. You can see the break right near the screw. I'm pretty sure it broke/stripped because the geometry is wrong. I also need a longer piece of allthread so I can get the geometry worked out. Oh, and that big ass joint at the front end is going to be replaced. It's overkill. I can make it much smaller. I may see about modding the original shift lever to use, since it's obviously strong enough. Still, until the shifter stripped out, I was hauling @$$ up and down the alley, so can't complain! Nick, now that the levers are cut down, I think I like them. I still need to remake the left one. At the very least I need to press in a sleeve and redo the bearing, but I think the geometry of the lever needs adjustment, so I'll probably redo the whole thing. Hooray for free materials! |
| MadNick:
A good start. Would definitely consider nylock locking nuts or at least use of split pins, especially for the pivots on the gearchange lever. Also some kind of sleeve for the pivots would be a better idea - steel on ali is not a good idea. Nick |
| jamoni:
Nick, you're speaking my language! The pivot bolts will all be replaced with smooth rods and cotter pins. I'll press in a steel bearing (or a ball bearing if I'm feeling froggy) on the lever. That'll keep the steel threads from eating the aluminum. All of the bolts will get locking hardware and liberal doses of threadlock compound. I don't want a pedal falling off at 60 mph. :( All of that comes after I get the geometry dialed in. I knew this side would be the hardest. It'll just take time. |
| jamoni:
Much better! The geometry is perfect! This thing shifts nice and smooth. Still need to finish boring the bearing seat. Then it's on to finishing up the pedals and pegs. I'm thinking about chopping off the original folding pegs and using those on the rear sets. They'd stick out a little further than I want, but hey, they're folding! |

I haven't worked much on this bike lately. My homemade milling rig had some hiccups, and I had to fix those first. Today I milled out the bearing seat on the shifter pedal and pressed in the bearing. No pics because it doesn't look much different. This time I used a different method. I chain drilled the perimeter of the hole, used the jigsaw to connect the dots, and then just milled till I had a flat surface. Checked with the calipers, milled to press fit, done! So much faster, so much easier, so much more accurate! Also, a decent bearing press is high on my list of things to acquire. I bent the handle on my vise. :/ So on the rear sets, the only thing left to do is square away the shift linkage pins and fab up pegs and pedals. I think I'm going to fab up some motocross pegs. We'll see. |
