Vertical Stabilizer Skin question
 
So it looks like I dimpled more holes than I needed to on the VS. Trying to find out if these are ok? Or if I need to order another skin?:mad:

Currently I am looking ahead in the plans to see if this is going to be an issue.

It is not going to be much of an issue. Those holes will have to get dimpled anyway but after you fit the fiberglass cap. When it is dimpled prior, it will not help with the fitting as well or as easy.
Did you dimple them with #40 or #30?
I suggest to leave them as they are and fit your cap. If it is with number 40, you will need to re-dimple them with #30 but do it after all the fit is complete.

I dimpled with #40. Sounds like it salvageable. Just going to suck. But no new skin needed.

This is where Van's suggestion to tape over the non dimpled holes really comes into play. Look over the drawings really well and tape over the holes that you are to skip before you start working the material.

Mistakes will happen and this is really of no consequence so I would not let it bother me other than looking it as a reminder to pay attention.

When you are in that stage, just fit the cap and if it was not perfect, then you can work on the fiberglass to make it perfect, more forgiving than the metal parts

I think the plans could use a little tweaking on this one as they say in the note on the page:

"NOTE: Tape over holes that do not receive rivets at this time to avoid accidentally dimpling or riveting these hole locations. See Figures 1 and 2 for locations."

in Fig 1 & 2 they point out in the drawing every where to leave open. Except they do not point at the top holes to not dimple or to leave open. So those didn't get tapped. Only the second squeeze did I stop and start to question why to dimple those so I stopped.

So warning to other builders tape the top four holes as well as the ones marked "LEAVE OPEN."

VS cap
 
If memory serves, the 14 VS is the same as the 7. Those holes end up drilled for #30 pulled rivets. The dimple won't matter. Most of it will be drilled away. Build on.

Managed to not get rivet gun straight. I am Guessing this would be a new skin.

Smiley
 
Maybe. I woul ask Vans first. They might suggest a rivet either side.
The smiley can be filled later unless you plan to polish.
I prefer a swivel set for that reason but many don't like them.

If for every smiley we were going to replace a skin, few of us ever finish a RV.

White this is more pronounced then a typical smiley, I highly doubt they would suggest a rivet on each side or replace the skin. Like Larry has said, a swivel head helps much avoiding this but also requires two hands as the head moves if not held.
