Turtledeck and Stringers

Post by cattrell »

I am having a real time trying to get the shape of my fuse the way I want it. Does anyone have any pictures of how they tapered the rear of teh turtledeck and the side stringers into the rear of the fuse? I am building a wood turtledeck with stringers just like the sides all the way up and over.

Thanks for the input.

I tried a lot of different combinations of formers and stringers before I settled on my configuration. Note that I added a wood stringer on the longerarm. This actually eliminates the flat section in the fabric and makes the top to sides transition more rounded. Also note the ends of the metal stringers are cut short and do not tuch the fabric.

Thanks ! Thats just what I needed to see. One questions though, do you have a detail shot of how you joined the stringers at the tailpost? I would love to see that.

Thanks again!

The wood stringers float against the tail post and are held together with light weight aluminum composite and space with a vertical supports.
