Hi again, The information from RennerUSA's site essentially is only relative comparisons of select strengths of Weissbuche (carpinus betulus) against maple (species not named). Unfortunately, I was unable to glean further information regarding properties of said hornbeam. A web search of "weissbuche" returned this site: http://www.w-l.ch/Holzarten/seitenholz/weissbuche.htm I can loosely translate most of the descriptions, but only guess at the headings for the technical information as follows. Raumgewicht: 0.75-0.95 Zugfestigkeit: 120-140 N/mm^2 Druckfestigkeit: 55-82 N/mm^2 Biegfestigkeit: 115-160 N/mm^2 Härte n.Brinell 12% Feuchtigkeit : H BII = 71 - 81 N/mm^2H BI = 30 - 35 N/mm^2 Now my question pertains to the use of hophornbeam in manufacturing flanges, jacks and hammer butts (ie. places less likely to add weight than wippens, shanks, etc.), and my reason for this inquiry is to ascertain whether hophornbeam's high expansion rates might exclude its use for these (currently I am not considering plastic). Thanks again, Clark
