Did so now. See if they still answer today. But I still want to build this tool, just for the sake of it.

comment Calibrate Tensiometer
Thanks, but not quite yet... I still think the forces are in no comparision. Imagine the whole costruction (scale, spoke and frame) are under 1600N of tension. If I now apply a small perpendicular force (maybe 25N through the TM-1) against the spoke, the measured weight may increase max. to 1625N, which is neglectable. The tensiometer only measures relativly how easy it is to bend the spoke sideways given a certain tension. Other components such as the scale don't get any perpendicular presure, and are therefore not part of the measurment. I still don't see a hazard for seriously wrong results

comment Calibrate Tensiometer
Yeah that makes sense, but the added tension to my spoke through the measuring tool should be neglectable compared to initial tension of 1600N. I don't think the bending of the spoke will have an great impact. I want to build something like discussed on the other board. Please click the link in my edited inital post (right at the bottom) and just quickly scroll through the thread to see the pictures. Then we might have the same understanding of what I want to do :-)

Thanks, yes my spoke type is not listen. The aero spokes are only 1mm thick. Park Tool has only listen aero spokes starting from 1,5mm thickness. I want to know if I can use the scale from the link, or if that will somehow give my wrong results. Furthermore I would like to know why the results from spring based scales in combination with tensionmeters would give me a wrong result.

That was my first idea, but I can't think of any place to mount the spoke, and I can't think of anything that weighs 160kg and is mountable to a spoke... :-(

comment Skid on small frame
I never removed the brakes and I mostly use then. Skidding for me is not about halting quickly, but just for playing around to get a better feeling for bikes. I now managed a short skid on a really clean surface, but shoved both legs against the stearing bar. Managing it sitting would be nicer though :-)
