I certainly don't view myself as a "master". I look at wheelbuilding as a light engineering procedure, not an artform. Having said that, I do find it immensely therapeutic and I like to do every stage properly. Spokes have to leave the hub nice and flat against the flange, they are stress-relieved repeatedly during the build, tensioned as high as the components allow and I like the rim to be as true after building up as it was before, if not even better.
Spoke tension is a particular obsession - we know that the strength of a wheel comes from the tension held within the spokes, and the tighter they are the less likely the lower spokes are to become loose under load, which is what leads to fatigue and eventual failure. There's little difference to the way the wheel feels to ride, but there is in longevity.
I see it as a chore, but once I get into it, then yes, it's very therapeutic. I like to do it properly too, it saves me he hassle of maintenance. I put my foot on the hub and pull the rim to de-stress mine, then re-true and keep doing that until it stays as good as it was before I de-stressed it.
Not sure about the maximum tension thing myself. I read that a well known wheel builder (Pete Mathews I
think) strings his wheels up very tight and in spite of his claims as being the number 1 wheel builder, I've heard a few stories about his wheels not being all that good.
I was surprised at how loose the spokes were on my mountain bike. I wouldn't say they are too loose, just not as tight as I tension mine (I do them pretty tight, but don't go mad) But they've taken some massive hits, sometimes with camping gear and are still as good as the day I bought them. I thought I'd have had to re-true them by now.
I wonder if stringing the spokes up a bit tighter would help prevent spoke breakages when I tow my trailer?
It does seem logical (to me anyway) that a higher tension in the spokes would handle torque better.
Watch out if you build a Miche Primato track hub though. The flanges have a nasty habbit of going ping. I won't use those hubs again. Besides, the bearings are crap if you ride in the rain.
