# Laminated Wood Bicycle Mudguards

## Step 2: Getting Started: Planning and Measuring

After puzzling how to mount my fenders so that they didnt interfere with my brakes, i decided that each fender would be made as two separate parts, one bit behind the brake, one bit in front. in the front of the bike, those pieces would mount via a metal plate onto the brake bolt. but because of a peculiarity of my bike, the rear ones would have to clamp onto the seat stays of the bike. as i said earlier, i wanted 3/8ths of each wheel to be covered by fender. i divided this up as 2/3 of the fender behind the seatstays (or front fork) and 1/3 in front. i calculated that with a 14 inch radius, the longer piece of fender would have to be around 20 inches long, and the front piece half that. so to outfit my bike, i would need three 20 inch fenders, one of which would be cut into two pieces, with half going on the front wheel, and one half on the back wheel. I also decided to make a set of fenders for a friend, who also built a bamboo bike, and will be my touring partner. so i needed to make six 20 inch fenders to outfit both bikes.

so this is the stage at which you need to figure out how much wood you will need. because of my racing stripe, i needed wood 1.5 inches wide and .5 inches wide (so that a light-dark-light pattern on the top layer would still be 1.5 inches wide).

here is how i figured out how much to get:

each 20 inch fender needed:
2 layers 20"x1.5"x1/8"
1 layer formed of 2x 20"x.5"x1/8" and 1x 20"x.5"x1/8" of a different(in my case darker) wood
X
3 fenders per bike (split between both wheels)
X
2 bikes
=
10 linear feet of dark wood in .5"x1/8"
20 linear feet each of same light wood in .5" and 1.5" x 1/8" wood

I got a little extra of both woods in all widths, just in case i messed anything up.
