These changes are modeled after what Denny Sleen had on his Legal Eagle UL at Oshkosh 2018. I first installed this tail wheel on LEXL SR 7-1/2 and it worked very well. My first try on ORV did not work well, broke the weld from cross bar to tail wheel arm. I had intended to use .035 for the cross bar but used a piece of .028 and it was not thick enough. When it was rebuilt I used all .049 material. The tail post on ORV is 3/4″ x .035. for the Tail wheel vertical post used 5/8″ x .049 and reduced upper portion to 1/2″ x .049 with the retainer made of 5/8″ x .049. This fit into the tail post nicely and no bushing is used on the tail post. The tail wheel spring came from Mcmaster Carr 2.5″ long, 1.031 OD, 0.781 ID Part number 9620K31. Fastenal is another place I have purchased springs. The vertical posts for the tail wheel springs is 3/8z’ x .049 and the cross tube and tail wheel wheel tube are both 5/8″ x .049 with the tail wheel axle 3/4″ x .049. This is a very simple way to build a tail wheel installation, saves weight and works well. The wheel came from Aircraft Spruce and is for Sonex type aircraft. Drilled lighting holes and turned off excess metal to lighten it up.
