AMMENDMENT- (added on 03-08-2005)
It was pointed out to me that the longerons do not enter the pre drilled holes at the lower engine bulkhead,in fact the cast metal pieces enter these holes instead,this is not mentioned in the instructions with the publication,well they would if they were long enough ! to get round this problem I extended these with brass tubing as shown below to enter the holes formerly taken by the lower longerons which splayed out the fuselage and brought to light the problem,to do this I had to cut through the very end of the lower longerons with a Dremel tool and araldited them to the bulkhead in the correct position shown,the vertical pieces now lie perfectly vertical as they should do.The photograph shows these modifications-
