Hi there,
Currently I am rebuilding a 1958 PA18. The fuselage has been media blasted and epoxy primed, no corrosion found!
But we will be replacing a piece of longeron in the tail and one crosstube which are bent.
For the lower longeron I have been searching what steel has been used, as I have heard that for $$$ savings Piper used 1020 mild steel from the rear seat back. Also I found out in this forum that all longerons have a wall-thickness of .035"... I have been measuring but I have .049". Anyone know this could have been standard? Is it correct that I can just use a 5/8 tube liner inside?
For the 3/4 x .035" tube.. which size liner tube can I use?
Of course all will be welded by a proffesional company.. but I have to order parts
Then next question... I also contacted Univair but they seem very slow with replying these days or just reply not at all...
I will be replacing the wooden stringers with metal ones... which p/n's do I order and how many?
Thank you for the help guys..
