    Ok guys, I kinda did this with Dougs wings but I am going to be starting on another set of our wing kit. Dan Williams is my rib man and he has the rib kit. He is starting on them now. I decided to make a good comprehensive build thread detailing pretty much every step in building our wings. could help future builders and just be fun to follow along with. Ill be starting with the top wing in the shop and the center section splice and prepping the spars while Dan builds ribs. these will be going on a WP-360 that we will be finishing to completion here. That thread will also be getting a shot in the arm shortly..... enjoy.......... :cool:

    As someone who is facing the imminent construction of his first set of wings, I will be following this thread with great interest. Even though you're building the wrong wings, I forgive you.

    hi Ian, if you go back through part 1 &2 of the ASIIS build threads I did a pretty good job there of following those wing builds along you could reference as well.

    Chris, is that for a compression rib, or a normal rib? Interesting how little diagonal truss-work there is.

    Regular truss rib pics coming soon. I built some compression ribs first because Smizo needed them for center section positioning. I hate building compression ribs because everything needs to be sealed with Clear Coat on the inside before they get glued and stapled. I'll show the painful steps. And before anyone speaks up, T88 exclusively in all structural areas, Clear Coat everywhere else.

    Hi Dan, which clear do you use inside the compression ribs and how do you apply it so it doesn't get into any of the t88 joints?
    Cheers,
    Sam

    It’s called “clear coat” made by system 3. Same company as T-88. Its chemically compatable so you can wait to dry and bond right over it with T-88.

    Thought it might be, you use the same product for spar varnish over the whole wing as well Chris? Or something compatible with the covering system?

    Just varnish it with T-88 and save yourself hours of waiting. The inside of the compression ribs that is.

    Will the inside of the compression ribs get just one coat of clear coat?? Or two?

    Thanks Bill

    I wish the Clear Coat was a hair thinner. I have also wondered about using it straight as an adhesive on certain things. I do like it though.

    First some compression rib build up. Then spar splice for front and aft spars. I have some simple fixtures to hold the spars in place for gluing. Center lines to line them up and a precision digital level to get them straight respectively. Popsicle sticks shim them to get them perfect. The splices are pretty straight forward and splice blocks are over size which are planed and sanded flush with the spars. Notches must be cut in the front spar front side blocks to clear the drag blocks. Anyways, get the spars straight, slather up the parts with t88, a couple of staples to keep them from sliding and clamp it all together. It doesn’t need to be made any more complicated than that.........


    Edit: note: holes in splice end are tooling holes from when tony machined the spars and end up filled with glue and buried in the splice......

    Also, in the last pic, the glue that blobbed out was cleaned up after the pic was taken. Easier to clean up with a sander down popsicle stick now than to let it dry and sand it out later when you’re trying to fit the drag blocks.
