Hi

Whilst waiting my for my tools I spent some time trolling the list and builder websites for hints, tips & tricks. One “gotcha” that was well discussed was the dent that comes from putting on the vertical stab skin and how to avoid it. In particular, the recommendation is to radius the VS1006, VS1013 and VS1005 vertical stab ribs in a manner similar to the instructions for the horizontal stab ribs (page 8-7 of the plans) taking off 1/8” or more.

While attaching the vertical stab skin, I noticed a small dent forming even though had followed the instructions and radiused the corners of the ribs. The end result was I took the skin off before the dent became too noticeable and reworked the ribs. In this case I took considerably more material off the rib noses making the nose rounding much more pronounced that suggested by the Van’s plans. The end result was no denting after all (just a barely noticeable bump on one side of the skin).

For what it’s worth, I found that the requirements shown for the horizontal stab are insufficient to prevent dents on the vertical stab. I ended up rounding the nose of each rib such that the side flanges were cut back by at least ¼”.

The only issue is how close you came to the rivet hole. Make sure you have the correct amount of metal between the rivet hole and the new edge. 1.5 x the dia, I do believe.

do not archive

Les,

You might consider bonding those nose ribs in place with a flexible epoxy or
pro seal. I lubed my clecoes which made cleanup of the excess easy. The
idea is to bond the ribs in while everything is clecoed. Then dissasemble
and clean before riveting. Don't use these clecoes again while doing the
fuel tanks, and or be sure to soak them in acetone.

The result on the second VS I made was great. I did the same on the HS.

Look in the archives.
