I agree, it struck me as using a convex surface to replicate a concave one. They appear to be concentrating on the small "peaks" in the cross-section, and not the "valleys" that are the main dimensions. Now if they filled in some so the valleys would be invert troughs and NOT sharp grooves, well. . DJE

I might suggest folks take a trip to a local RR museum where there is most likely a Budd car either on display or out back in the to-be-rennovated pile of cars. A close look at Budd fluting will reveal a sort-of parabolic curve (shaped by bending sheet metal) and a sharper-curved "tip" that rides over the edges of the bent sheet metal to form a more-or-less waterproof outer surface. And that is for the large flutes. The smaller flutes on the roof are sort of like a square wave (electronics speak here) about 2" wide and 2" deep. Divide that by 64 and you will see the small flutes in S scale are very tiny indeed. The true contour of a Budd flute is unlike anything available in sheet styrene or commercially available shapes. When looking at HO Budd cars, it is soon obvious that the large flute contours bear little resemblance to the prototype, but the visual effect is generally satisfactory to most modelers. Perhaps the Pullman-Standard flutes are easier to model. No comment about that since I have not looked at P-S flutes up close and personal. If Kaslo could be convinced to make a "blank window car", then perhaps all the creative modelers out there could cut their own windows and achieve their desired end goal. I would think that 25 or 40 orders might be enough to make Kaslo think seriously about doing just that since he will already (eventually.....) have all the other parts and tooling needed. Just a thought to help those with strong desire.......Ed L. [Non-text portions of this message have been removed] ------------------------------------ Yahoo!
