Wheel Lacing
This is the second time I've laced my own wheels and the first 3x pattern. Referenced
Sheldon Brown for the overall how-to and a couple different sites for spoke length,
ebikes.com and
kstoerz.com. The sites gave differing values using identical hub and rim dimensions. To be safe I decided to use the longer lengths from each. Figured it was better to be a little too long than short. Had to grind a couple mm off some of the spokes once everything was tightened but overall seems to have worked out.

Pieces parts for the rear wheel and initial lacing.
Finished and trued rear and front wheels.
These were a bit more of a challenge then the first wheel I laced for a previous build. That wheel had the same dishing side to side. Both of these wheels were different side to side. The rear only slightly but the front quite a bit. I used a spare fork as a truing stand for the front with a zip tie attached to one side. The end of the zip tie helped me judge how straight the wheel was running. Flipping the wheel in the forks left to right helped me get the rim centered to the hub. Really taught me how nice it would be to have an actual truing stand. Can't say how many times I accidentally hit the zip tie when flipping the wheel and then had to re-set it.
The rear wheel didn't vary side to side as much but the flipping process was the same. I didn't have a frame handy that would accommodate a 170mm rear hub to use as a truing stand so I built one from a donor rear triangle and scrap tube.
