More planning on the frame.

I did a deck on scetch with main thought on a chain line. This was done after aquiring some inspiration from other people's work. Raising lowest line of frame solved lower chain line easily. Higher line is more difficult since it crosses frame on it's way to rear wheel.

One solution would be to build rear fork separately so that this would make necessary sideway shift. But since I want to make frame sides from single piece because of visual reasons I want to come up with another solution.

This is one option I came up with. If I make a hole on a frame I can run chain through it. This might also hold chains in place and prevent chains from dropping off.

I need to think this through. There are some ingredients of catastrophe in this plan. It might be a good idea to solve this before actual building phase.

Some measurements of construction.

I was on a drawing table the other day and scetched a bit. After setting some measurements on a frame design it seems that I really need to think about chain line. It would also be really helpful to have wheel set and cranks at hand so I could do some real life measuring and fitting.

Some measurements have now been decided. Wheels will be 26 inch set. Width will be decided later. Front cranks 30cm from ground and 70cm from saddle. Front rork angle to frame, roughly 60-65 degrees. Rest will follow.

Here is the scetched idea with some apparent problems.
