    The original longerons consist of two 7075 angle 3x1 1/2x 3/16 riveted together by a 3x3/16 plate. If I was to replace the original with an extruded channel (same dimensions)...would they have a similar strength?
    If it were me, I wouldn't dare make a change in construction like that without consulting a few qualified engineers.

    Ha...That's why I'm asking you guys. I ask dumb questions, and you protect me from making stupid mistakes.

    Hi John-

    Just f/ref.- Tiernay Metals was taken over by Trans-Star Metals some years ago & then a couple years ago was bought by Castle Metals & is still the mfg. source for aerospace aluminum extrustions. I've dealt w/the Kent, Wa. branch thru all the company transitions for both my job at the seaplane airline & f/the lengthy & complicated Grumman Goose restoration I've been ramrodding & they are an expert & invaluable resource w/great service. The previous contact ref. was a good one & here 'tis again:

    Castle Metals Aerospace
    20826 68th Avenue South
    Kent, Wa. 98032
    1-800-421-1133 / Fax: (253-854-7401

    Ask for- Heidi Frederick / Sales Dept.

    The orig. Tiernay & later Trans-Star product catalogs are prized refs. for extrusion profiles, shapes, dimensional specs. & part numbers (especially the Tiernay catalog, which includes most of the vintage Alcoa & Kaiser Aluminum Co. die numbers).

    It's been awhile since I gave you guys an update...

    I just got back from a long weekend in California. On saturday I went to the Planes of Fame Air-show. The flying was amazing and just being in that atmosphere was inspiring. It gave me a little kick in the butt and I can't wait to start working on the plane again. During the show I was able to meet some of the original Tsunami crew and got the chance to talk to Brian Sanders and Steve Jr. You could see it in their eyes how special the plane really was to them.

    On Sunday I drove up to Calabasas and had lunch with Tsunami pilot Skip Holm. It was incredible listening to the stories he had with my Grandpa and some extremely close calls he had in Tsunami. Skip was very supportive of the project and is going to do what he can to get the aircraft completed.

    One story he told me about was when they were doing flutter tests up in St Cloud, MN a month before Reno 91. Skip said he would go to about 10,000' roll inverted, dive straight down and push the throttle full. When he got to 600 + knots he would release the controls and hit the stick as hard as he could to get the plane to vibrate. He was doing this all day until the last time the right elevator ripped off the plane and the left one broke along with the 1 1/2" actuator rod. At that point he was barreling straight down starring at a corn field. He radioed Jack and told him his situation, Jack told him to get out. The canopy wouldn't open and the trim wouldn't respond.

    All Skip could think about was his fathers farm and how pissed he would be if someone crashed in his field. Emergency vehicles would be scaling every inch trying to find him while plowing down all of the crops and destroying the harvest.

    Finally he got the electric trim to work and was able to pull out twenty feet above the field. Jack got back on the radio and insisted that he jump out and that it was only an airplane. Skip radioed the tower and declared an emergency landing, Immediately Jack radioed the tower from the ground "39JR bailing out 2 miles south of the field" the tower said "who is bailing out and who is landing?" Skip responded "the guy in the airplane is landing"

    Skip was able to land the aircraft safely, but Jack was pissed. He screamed a little, jumped in his MU2 and left Skip stranded at the airport for 7 hours before coming back to get him.

    That shows the kind of pilot "Skip" is. Those test pilots are a certain breed. I still think he would have won the Gold in another year or two in Tsunami.

    Hey LittleJR... I see a good story teller in your writings... Please promise us to keep a journal of the build (you're doin' a pretty good job already) and keep the thought in mind that a book about the original build with stories from those who built and flew her would be a great thing.

    I think you have the writing skills to make something like that happen...
