Is the site for EPI Engine services run by Jack Kane- Who would havew to be one of the most "tuned in"guys I have spoken to. Jack's Site provides an in depthe engineering analysis of the secondary problems and proceeds to engineer and manufacture an appropriate alternative shaft.
Jack's site also covers the development of his "Mark 17" Gear box which is part of his project to allow the installation of a "Solar T62T-32 Gas Turbine" within the confines of the engine bay - thereby providing a lower C of G , significant increase in power accompanied by a drastic weight reduction. The other main benefit being the abolition of all the "Rubber Bands" to the MR and TR drives. I have 2 turbines sitting in Jack's workshop waiting for him to finish this project but unfortunately he is snowed under with "real work" and this is basically just an "As time permits" situation, so progress will undoubtedly be slow. Which gives me time to modify the fibreglass panels on my project.
