Building Bicycle Fender Hardware


My friend Stefan gave me a set of Planet Bike Freddy fenders. The only issue was there was no mounting hardware included. The stock hardware consists of stainless steel struts that mount to the frame or fork on one end and a little pass through fastener on the other end.

The stock struts are a 1/8" diameter stainless rod with an eyelet formed on one end. I wanted to duplicate the eyelet because it looks nice so I made a simple wire bending jig. Here's how the front struts turned out:


The struts got me halfway there, but I still needed to build the hardwa
re that connects the struts to the actual fender. I was able to turn these parts out of brass on a lathe:



These parts turned out pretty well so I think I will try the same thing for the rear fender. The rear fender has a different bend pattern so I may need to make up another wire bending jig.

First Post

My plan is to use this blog to document my projects. I hope that anyone interested in what I'm doing will comment on the site in an effort to improve or add on to what I'm working on. I am a mechanical engineer with an interest in mechanisms, machining, electronics and cycling among other things.

One project that I am currently working on is a homebuilt laser cutter. Essentially it is an x-y gantry with a 40 W CO2 laser and optics to guide the beam. I have been documenting the laser build on at this site:


In the future I will keep all of my projects on this site, but the laser will remain on the buildlog.net site.
