HS assembly right side ongoing - 4 hours

I started off the evening working on the new HS00006 ribs. I decided to order new ribs when I decided to redo the front spar. I'm sure the old ones were fine, however I wanted to be sure that each piece had a correct fit. and for $20...why not start fresh.

 I marked each one left and right and then trimmed each according to the plans. I drew centre lines and then drilled my holes.

I then moved over to the HS angles. I was very careful this time to not take too much material off. I ran them threw the band saw. I was nervous as the band saw is a little ravenous at times if you are not paying attention. But I went slow and in the end...I didn't mess up.

Then I bent the angles to 6 degrees each end.

I cleco'd the right HS assembly together and then put the skin on. I worked the HS00005/00006 ribs. I drew all my centre lines out and ensured that all lined up. I then started drilling holes as per the plans.

After I was done drilling, I was very happy to see how the holes lined up in the front flange of HS00005. The top and bottom holes are a bit blind and its tough to get them to line up. I checked, checked, and re-checked before I drilled. And the proof that it worked shows.

Tomorrow I will finish off match drilling the new parts. and hopefully I can complete the left side....again.

Building tip - In retrospect, the evening took quite a bit of time. But I proved to myself that the front spar of the horizontal stabilizer is something that you just don't rush if you want to have straight even holes. The key to everything so far on this portion of the project is to slow down.... (The VS and the HS rear spar gives you a bit of a sense that you can rip through pretty quickly). For  this...slow and straight!!!!

Mark centerlines on almost every part. Draw centerlines on the table and then as you cleco...it becomes clear how straight you are. Then when you start clecoing parts together. lines are visible through holes and every little bit helps ensure straight! Use a drill press! Hand drilling through thick materials ends up with slightly crooked holes. And lastly....read the instructions, and the plans, and then read them again....and only then...start working.

Working away on the HS front spar... Third times a charm - 1.5 hours

Not a whole lot of time available to work on the plane tonight. So I jumped back to the horizontal stabilizer. I received the replacement HS-710 and HS-714 angles from Van's yesterday. (Grrrr..The third ones!!!) I hope I really nail it this time.

I carefully marked out the center lines on each side of the angle pieces. Then I countersunk the two center holes of each angle (Very much a pain to re-set the countersink cage after I changed it for the rudder counterweight)  I then cleco'd the front spar assembly back together and ensured that the assembly was straight. Everything was bang-on! It really helped when I filed the ends of the front spars where they met on the previous Friday. Now with the new angles...it all lined up. 

I used the drill press and matched drilled all the holes inboard of the bend lines with a #30 bit. Once complete I then rechecked the front spar assembly and confirmed that it was perfectly straight even when sitting vertically on the HS-714 angle. I can safely say that I did less than 1/32" difference between the two ends. I was pleased with the fit of the countersunk holes as well cause its really tough to get it to nest nice.

Third time's a charm!! Like my tool box... Ahh...I just have to laugh! Well...At least it's perfect.

Do I have a name for the plane now??? We shall see.
