I am happy to send you a model or DXF file, so you can get a local lasercutter to fabricate it for you
Gotta be honest; pretty excited about the idea!
Interesting too that you mention this, since I was thinking to give two arms (for a Shimano CB-hub) away as a prize award for this buildoff.
If you give me some measurements:
- Coasterbrake anchor slot hole (is that correct English/American?)
- Anchor slot hole center, to the 'band wrap/clamp' or frame attachment hole center.
- And your personal preferences in design.
+ you are lucky that you are not in my class, else I would make it extra ugly
[edit] I see now that you have a Shimano Coasterbrake? Or is that a Histop?
Love your dropout extenders by the way, they look beefy. This is going to be one beautiful bike for sure! Already is.
