Re: Chopper 300
Did you think to cast the brake calipers in resin for future projects? I'm thinking since you already hacked them.

Re: Chopper 300
So, Ketje asked for some pics with the forks. This is just a mock up with tube mounted in the triclamp but you see where I'm heading. Some issues when I got it jigged up, front wheel looks to small, ugly gap above front cylinder that I would like to remove but don't know how. If I alter the frame I think I'll mess up the tank mount.
Forks are mostly scratched using 4+5 mm aluminum tubing. To get the widened ends of the outer tube I mounted some 6.3 mm plastic tube. I'll have to take them in a few points of a mm and will make them sloap in against the tube using putty. |

Re: Chopper 300
Hey Joël, looking good so far. The front wheel looks a bit small but that's because of the distance between the axel and the tri-clamp. If you decrease this it will look much different, but you'll also have a different bike in the way it stands.

Actually, that's what I would like but I guess I'd have to rework the frame/fork mount angle. |

Re: Chopper 300
Also, ride height feels a bit on the high side, aprox 24 cm full scale. Lowering that by changing the rear wheel rocker it would also adjust the front fork settings. But it would also mean taking quite a few steps back in the process.

Re: Chopper 300
One way to make the front wheel look better is to add a "chin spoiler" on front of the frame. This will "fill in" some of the space between wheel and frame and it would add a sportier look at the same time

Re: Chopper 300
Yes, that is an idea, I will probably do a mix of smaller changes like lowering the frame some millimeters from the ground and adding the chin spoiler. I've also made the desicion to leave the needle chaped rear fender out of the build. It will be tough to fasten it in the right angle and dry fitting it doesn't look to good.

Re: Chopper 300
Googled some chopper forums and found that 25 cm (10 inches) of ground clearance is way too high. Some has gone as low as 5 cm (2 inches) but 10-12,5 cm (4-5 inches) seems most right if you want control in riding curves.
I'll have to lower the frame to half the existing height. It was obvious that my existing swing has to be altered. I spent the evening last night trying to bend a new structure but can't get it right. Tried plastic pipe/rod and aluminum tube which was what I had at hand. Made a blueprint but it is really hard to make the bends at exactly the right spot. My thoughts are starting to lean towards soldering the swing with brass. Only problem - I've never soldered anything... |

Re: Chopper 300
Well, well, well - hello crazy idea of making a single sided swing instead! Easier to bend and rougher look. What do y'all think??

Re: Chopper 300
CAD and 3D-printing just ain't my cup of tea. Back to the drawing board, or sketch book rather, making a new swing arm.
