[QUOTE="Phil Graham, post: 83642, member: 430"] Re: Extending the forks on Sumner Eventer 25's Brandon, You've got no wiggle room with a load hang point beyond 13" along the fork length. See pp. 12 of the Sumner Eventer 25 manual here: [URL]http://www.sumner.com/sumner/images/file/upload/operation_manuals/Eventer20_25_OpManual2010.pdf[/URL] Further, there's no way anyone should recommend for you to bridle at this 13" point along the forks, because we have no information about the flybar rating in any direction except for the downward static load. The very substantial shear and/or torsional loads that would be applied to the flying frame by such a bridle have not been certified for by the array manufacturer. No way anyone who took statics in college would ever put their stamp on this without a number of other load tests or FEA simulations.
