Well of course it wont.. you have to make sure that the WBW (KR X WRW) is also to specification. > If you set the FW > at maximum and set up your SW's to a corresponding curve without measuring > the BW that corresponds to that relationship you could end up with a nice > curve and a BW of 50.

If you set FW to maximums, Select and install a SW curve for a given overall Ratio and BW specification then you all you have to do to make all the bricks fall into the right places is insure that the WBW is correct for that specification. That means just making sure that your KR times your Whippen radius weight ends up being 9.0 grams. When all this is done, then whatever uneveness remains is due to friction issues, and your BW will be as you specified. Rewrite the Balance equation... BW = (R * SW) - FW + WBW. Davids Smart Chart lines SW Curves up against given R's that yeild FW Ceiling values for a given BW spec with WBW at 9 grams. I have done this on 9 actions so far... and I can assure you it works perfectly. It is tho... a bit confining as you are limited to what the FW ceiling table allows for in any given situation. But it does work out as I have described. > > David Love > > -- Richard Brekne RPT, N.P.T.F. Bergen, Norway mailto:rbrekne@broadpark.no
