Thanks for all your comments saying it is impossible to get the torque value correct on all the spokes.
I understand that.
I need the torque spec so I can get them closer to what they needs to be as I keep the tire true.
Spokes stretch. Especially when you ride.. on rough roads (dirt, river beds, etc)
Loose spokes = broken spokes
When I put the torque wrench on 10 in-lb and NOTHING happens on ANY spoke.. hmmm.. Need to tighten them up.
I said TIGHTEN.. not TRUE!!!!
I use the time honored method of starting at the spoke beside the valve, turn 1/4 turn, skip 2 spokes, turn 1/4 turn, skip 2 spokes, turn 1/4 turn, etc. Go all the way around. Go to the next spoke from the valve.. same routine, all the way around. Got the next valve from the spoke, and one more time around the wheel.
That's right THREE times around makes one "set"
Why skip 2 spokes? Because that puts you tightening on the opposite side of the rim.
Spin the wheel.. make sure you are still "True" (should be, you did the same thing to each spoke).
Keep going round and round and round. Eventually, the torque wrench will hit the value you want on a spoke.
I will be setting my wrench a bit below the spec. That way I can finish out the set of rounds with the non-torque wrench. A 1/4 turn ain't gonna put you over if you started out a bit below.
Sound OK?
Oh WAIT.. somebody is sure to say that not all the spokes will have stretched the same amount. GIVE ME A BREAK..
I will do what I need to do to get them as tight as they need to be while keeping the wheel as TRUE as I can.
Anything will be better than loose as a goose and the rim wandering all over the place under load.
