Step 1: Front Wheel
hole spaceing (measured between hole centres accross the hub.) = 38.4mm
hub width: 68.4mm
608mm diameter rims.
Step 2: Choose your spokes.
Basically just take a set of spokes way too long to build for the equipment you have.
Take a best guess at the twisty pattern. I've included 3 configurations in this how-to as a guide. I don't know of any spoke calculator for doing these patterns...
Step 3: Lace very loosely one side of the wheel.
Step 4: Now the tricky part. lace the other side
Step 5: Put in the second half of the spokes.
try and lace them opposite each-other ie for each one on this side of the wheel, insert one on the opposing side next....
Step 6: Tighten and true wheel
the secret is to tighten all up to firmish, then to proceed very slowly, sort of 1/4 turns on each spoke
Step 7: Ride, and re-true.
Step 8: Alternative Lacing pattern.
62.4mm hole diameter.
66.8mm wide hub.
266mm long spokes.
540mm diameter rim.
