So off to my local bike shop and sticker shock! $44 for a bit of plastic and some mounting hardware! I knew I could beat that AND have make it look better. Good thing I planned for this occurrence in advance. So off to Ace hardware across the street and 4 minutes later, I have a spool of 14 guage steel wire and a .125"x1.5"x4' strip of aluminium stock. I already had the mounting hardware I needed. Total cost? $13
I made the fenders and didn't document the process, so I'll walk you through with the pictures I have and draw the rest.
I'll walk you through the process of making the rear fenders and then give a guide on how to do the front ones.
Let's get started!
Step 1: What you need...
3x M5 machine screws (can be socket, phillips, flat, torx, w/e you can find and have a driver for)*
6x Washers (or more)
1x Aluminium flat stock (3mm/.125" thick)**
1x Spool of 12 or 14 guage steel wire***
A hand saw or band saw
Flat file (you can use any kind you want, but flat is easiest)
Drill bits (1/4" & 3/32")
Sand paper (120grit)
Center punch (a wood screw will do)
Some puddles to test your shiny new fenders on!
* Depending on your bike, you may have trouble with really long screws. I would suggest something between12mm and 16mm or you may run into your hub or kickstand mounts.
** Depending on your wheel size, you may need more than 1 piece of aluminium stock. My wheels are 20" so I only needed one 4' piece for both wheels.
*** how much you need depends on your wheel size, but a good rule of thumb is the radius of your wheels times 5.
