I have a bike with an extended frame in the back, being able to accommodate two small children. For this back section of the bike, I built a custom rain cover, for which I constructed a simple wooden frame.
This wooden frame can be imagined as four polls connected to each other at the top, and on the bottom, resting on the metal bike frame (like a small roof), creating 4 contact points with it. The wood polls are 2cm wide (0.787402 inches), the metal frame around 1.5cm (0.59 inches)
The question: How do I connect this wooden "roof" to the metal frame?
Ideally, I don't want change the metal frame too much (so drilling a few holes is fine, but no soldering).
Things I thought about:
- drilling a hole in the polls and put zip ties on: not strong enough, tends to move around
- drilling a hole in the frame and connect with wood using metal plates (having holes): also feels like it might move around when windy
