| |  Just finished, grocery getter!
I am having hard time with picture downloads. So i hopefully attached pictures. Clueless to this system. Anyway. this is a 1980 schwinn cruiser frame. stock bottom crank and bearings, cheepo springer front end in good shape that I got with bike, nexus 3 speed hub with electra rims and flame pattern tires. Custom cut front and rear schwinn fenders. Custom made delron motor mounts. I sand blasted parts before shooting mars red auto paint. New bars, seat, basket, and hub shifter. 80cc motor kit. added shims on both sides of rear hub to help chain clear frame. replaced mounting studs with hardened. Am toying with 1.5v led lights in parallel for tail and running lights with 6v r/c car battery under seat to back up charging system. Not sure if i can hook up battery direct without it getting overcharged. Hey, if by seat gets hot, I guess i will figure it out.

Very nice build! Welcome, these forums are great with lots of information and good people.
I do have a question, what are these delron motor mounts? Do they protect the frame and/or reduce vibration? Any more info would be great! |

Delron is like nylon, but harder. Its what the gears in a lot of cordless drills are made of. I got a 1 inch by 10 by 20inch sheet of it from when i worked in robottics. I cut a 1 by 1 1/4 strip. then cut two pieces and drilled them for studs. I needed more clearance from sprocket. I groved front mount to fit frame tube. added longer hardened studs. then drilled and tapped long 1/4 inch bolt thrue rear clamp, and tapped it into rear alloy mount for more support. replaced nuts with hardened, and doubled up on them. The delron wont reduce that much vibration, but hopefully enough to save studs and frame welds.

I love your bike. The basket is tied down very well and since i lost my hangon basket and almost ran over it when it jumped off I salute you. Be sure you tie down you packages well. Any big bump and they will be all over the road.
You did a great job on the bike. |

Ahhh ok..so it's similar material to the tools used in PDR to tap down high spots.
I have an upcoming project for my g/f's fathers ratfink bike and he wants it done PERFECTLY. I don't blame him, but I figure I can use this so I don't scratch the frame. Where can I pick this stuff up from and how m uch does it cost? |

I might be the only one here that actually thinks friction drives are superior to chain and sprocket or even belt and pully drive.
If you have a good kit or good system to add friction drive to an engine let me know. I think A friction drive with a good clutch type engine would be ideal.
You probably should start a thread though to get maximum coverage for your discussion. |

And if you lose your job because of all the time you spend on your bike, you can always get a paper route.
