Without finishing anything yet, I already started the
third piece. The reason is: To finish the VS I need some bucking help
from my wife, but she got sick. And I couldn't go on with the Rudder, as
priming was the next task and had to be done on a weekend. |
| Here you see the reinforcement plate of the read spar.
The plans says: Deburr the parts. This innocent little sentence keeps
you busy for three hours (OK, I also matchdrilled some holes etc)
In the background you see the almost finished VS. |

The ribs cleckoed to the front spar. It is almost 3.5
meters long. The next thing is to put it into the skins. The mattress
you see comes from an old child bed. It is really useful to put
assemblies on because they do not get scratched. If you just put them on
the table and deburr something, the buss scratches something so easily.
Deburring skins on it is great too. Others put a piece of carpet on the
table which has the same purpose. |
| This is probably a good preparation for the wing
building: You put the skins into cradles. With all holes prepunched, the
cradels are just there to help to hold everything together. The
precision is in the holes, not in the cradles. |
 |
 |
The skeleton has been inserted into the skins. The rear
spar will be inserted on top of all. |
| Everything put together. From here until ready for
priming it took me almost 15 hours. There are about 1000 skin holes. all
these must be drilled, deburred, some countersunk, and... |
 |
 |
... dimpled. Most of the dimples can be done with the pneumatic squeezer,
but all in the center of the skins must be done by brute force. Later
on I remarked that brute force alone is not enough. It needs even more!
I had to redimple almost all skin holes!
I have no picture of the current state of the HS. Everything is
riveted together with the exception of the rear (upper) spar. After
inspection it will take one or two hours to complete. |
| Well, it took 4.25 hours to complete. When doing time
estimates, I should double it from the start... |
