I cannot comment on the method and the accuracy yet,
but compliments on the well-structured post and colourful picture!

Thanks. It took me a while to clarify my explanation and make the picture, so I appreciate the compliment.

I first posted wheel build in the Schlumpf hub thread:

Schlumpf hubs: general discussion

Hi everyone, I thought it is a shame that most of the talk of schlumpf hubs occurs in the ‘brand new broken schlumpf’ thread. So with the teething problems of the first generation hubs being rectified (in a very noble manner by florian i must add), and more and more people enjoying this pretty amazing new piece of equipment i thought it would be time to start a new thread for people to talk and share ideas about their Hubs, the unicycles they are in, shifting techniques etc. I’ll start off, I …

That original post had a much less clear explanation of spoke lengths, so I hope this will clear it up. I also made a few incorrect guesses in determining spoke length. I originally thought the spoke lengths would likely vary between the lengths calculated for a 32h hub/rim and those for a 36h hub/rim. I bought spokes at 2 lengths in-between the 2 calculated values, but it turned out I need 4 different lengths to make it work. I then had to grind down some o f the spokes and dig up some spares I had to get the correct lengths.

It would be interesting to tweak the equations used for spoke length to calculate lengths for 32h rims to 36h hubs and vice versa. I thought about doing this instead of just guessing at spoke lengths, but usually by the time I start my unicycle projects, the nerdly part of my brain is already done for the day.
