Last week we patched the chain cutout on the right side
of the bike (this fender was on Adele's Sportster before)
so this week we continue modifying it to fit the swingarm Knuckle.
Like before we used a wooden beam between seat and ceiling,
so that we can raise the table to see how low we can mount the
fender without it hitting the tire.
The fender was actually a bit too narrow for the 170 tire so
we cut it in half and added a tapered insert. The idea is to trim
the sides at the back and extend the sides at the front, so there
is no clearance issue at the back. We also added some temporary
mounting tabs so we can check the fender in the frame in the same
position each time.
The insert was tackwelded in place
first, then after grinding those almost flat the whole thing
was planished before final welding. Then after final welding
more planishing. The idea is to not make the metal thinner in
the welded areas, so all sheetmetal must line up perfectly.
Next we will make the final mounts and then trim and extend
the sides
