At some point I will be wanting a steel rim in the front
wheel, but for this summer this will have to do, so I installed
a new Avon Speedmaster. Check out this little tool that helps
pull the valve through the rim and also can be used to screw
out the internals of the airvalve. Next I needed a brake anchor
for the front wheel so I made a CAD drawing and had the contour
watercut from 10 mm thick stainless steel.
Aad bent the brake anchor into shape for me using
a giant pressbrake at his dayjob. Now when you bend thick materials
there is quite a bit of deformation on the sides so I machined
off some material on each side to make it straight again, drilled
and countersunk the 3 holes for the mounting screws and polished
Aad welded on the lug that fits into the drumbrake
slot. I used one of the front fendermounts between the brake anchor
and the forkleg, after reshaping it and giving it a quick polish.
Next job: front brake cable...
I found another cool tool to help make the brake
cable, (I admit it, I am addicted to tools..) the idea is to slide
the copper nipple over the steel cable and then with this tool
deform the end of the cable into a ball. After soldering this
gives a very strong cable, stronger than soldering alone.
In the last installment I designed a new housing
for the USB sockets and sent off the file for 3d printing, After
putting in the electronics I filled up the housing with a 2-component
silicone rubber which seems to be taking very long to solidify..
Anyway, the USB socket is mounted and it works. I think it is
almost time to take it for a ride!
