<div> </div>
<div>Reasoning that the knuckle relocation (c) resulted in a BW &
SBR reduction of 5</div>
<div>and a friction factor reduction of 3 (b - c), it's a safe bet
that the outcome (e)</div>
<div>would have reflected the loss of the gains from that procedure
had knuckle</div>
<div>relocation not been done. %</div>
<div><br></div>
<div>So had I relocated the stack before relocating the knuckles, I
might have been</div>
<div>torn as to how far I wanted to get into it. I am happy with
the results and probably</div>
<div>would have move the knuckles anyway. I never let the thought of a
little extra work</div>
<div>stop me before.</div>
<div><br></div>
<div>But knowing these results can influence your actions to achive
the biggest-bang-for-the-buck.</div>
<div><br></div>
<div>It's amazing what a little extra effort can do for an action and
I never can think of a good answer when a customer asks, "Why
wasn't it like that from the factory"?</div>
<div><br></div>
<div>However my response to: "How did you do that"??</div>
<div>"Elfin Magic".</div>
