Re: David’s STI Build N413KF
First day actually working on the airplane! 1.5 hours to pull all the hardware for the horizontal stab and elevator section, try to do some reaming, realize it wasn’t that easy and I needed to modify the reamer as others have mentioned here. Ended up grinding it down with an angle grinder until it was small enough to get a box wrench on the end. Painters tape came in handy to prevent scratching the finish on the elevator and stabilizer.
Not sure why they send a reamer that is supposed to be chucked when you can only really use a drill to get a couple locations (unless you’re ok with reaming crooked) but that’s ok all part of the fun of using some creativity.
Looking forward to my first attempt at hysol tomorrow on the ribs!

Re: David’s STI Build N413KF
I got half of the ribs fitted on the horizontal stabilizer I sanded by hand and went slowly not knowing what I was doing exactly. 7 out of this 9 I added rib stiffeners to prevent warping. The other two are against metal so no need there. It was my first attempt at Hysol ... Mixed up way too much but I guess that’s part of the learning process. I was conservative with the amount I used. Going to let these ribs cure and tomorrow start on the other half but I think with the dremel sanding drums this time now that I know what I’m looking for. https://uploads.tapatalk-cdn.com/202...16c9f61392.jpg

Re: David’s STI Build N413KF
The fun begins! Sure like the black powder coat.
Re: David’s STI Build N413KF
You are started, good luck. Just keep doing one page at a time is what they told me. I'm still at it ..... You learn a lot, right after your done lots of times. haha
Re: David’s STI Build N413KF
Woah the rudder has pre-welded supports now? I was wondering when the airfoil design would become a weldment. Hopefully that gets expanded to all the pieces that require airfoil.
I saw a highlander not too long ago with a welded airfoiled tail and thought they were on to something great.
Re: David’s STI Build N413KF
About three hours today checking the fit of the horizontal stabilizer ribs, sanding, scotchbrite on the frame in the area they would be hysoled to. Cleaned everything up with alcohol let that dry and started with the hysol checking measurements as I went. First thing I realized is that my fat fingers result in anything but a “neat” appearance of the hysol although it got a bit better as I went. I’ve done a lot of painting and caulking in my time which turns out nice but this is a little different working with the angles of the ribs and frame and tight spaces. Cleaned up the excess with a rag with a bit of alcohol on it so it wouldn’t look like a complete disaster but didn’t sweat it too much since my main concern was that the ribs were firmly attached and straight. No one will ever see any of this again after the Oratex is on!
I ordered a 36 inch piece of balsa from Aircraft Spruce yesterday which I plan to use on the stabilizer and elevator wingtips. I’m flying a trip the next couple days so I will let this harden up and then move on to the elevator when I return.

Re: David’s STI Build N413KF
Good luck on the build!!
Hopefully you lined up the ribs on the elevator before you glued those down on the HS so that you are sure they will line up with each other. On mine, I measured like the manual said originally but if I had secured them that way the ribs would not have lined up identically with each other between the elevator and HS.
Re: David’s STI Build N413KF
I did I had to shift the HS ribs in two locations slightly from the book measurements to make sure that they would line up with the elevator ribs and not be blocked by the metal components.

Yesterday was the first time I ever mixed up the correct amount of Hysol. And yes, the technique of not getting it all over the place takes a few tries. I'm certainly glad it all gets covered up.
