Has anyone built a wheel with a lefty hub? What are your measurements on the lefty hub? Do these sound right? I am lacing it to a ZTR Olympic 347, does 257mm non-drive and 261 drive sound right?

My measurements are:

Left Flange:

dL: 58.00mm
WL: 18.55mm

Right Flange:

dL: 45.00mm
WR: 31.56mm

Thanks for your help in advance!
