Progress! 10 steps forward, 2 steps back ..
 
We finished the vertical stab, rudder, horizontal stab, and elevators+trim tab .. started on the tail cone this weekend .. but dropped the bucking bar during a rivet and trashed the bottom skin .. ugh .. this hobby needs a therapy hotline! :D

Yup, luckily that hasn't happened to me (yet), but I've heard horror stories. Therefore I always put a towel down below in case the bar is dropped.

It's a $60 (price of the skin) mistake so not the end of the world .. happy that parts are cheap'ish!

I did the same. No chance of recovering the skin?

shipping
 
That piece of skin may be only $60, but it will cost you a pretty penny to ship it. Ask me how I know. On second thought, no, I'm only thinking happy thoughts. :D

Yea, just got the shipping quote, ouch! Now it's a $200 mistake.

I'm sure a painter can fix it but it's pretty bad. I'm used to smileys here and there but this is about 1/4 deep and about 2 inches long. It will have my OCD on overdrive. Can't live with it, already removed the rivets.

Good job! I wouldn't put up with it either, so while it's somewhat costly, you will feel better when it's replaced.

Gravity is just going to happen. Those foam mats that go on the flooor around the workbench are cheap at HF. I keep a couple of sets on hand to cut up for all kind of uses. Great for padding/protection in the situation you just experienced.

Maybe a cheaper fix?
 
I would try a rivet gun with a flat set, pressure on the low side, and see if you can tease the dent out. Lay the skin on a piece of MDF and see what happens. This won't be the last dent you put in your baby. :mad:

Sorry to hear about that. I will try to learn from your "event" and prepare for the inevitable tool drop when I get to that stage.

Did you consider alternative repair methods? For example, using the trim bundle to create a repair panel at that location may have been cheaper. And the weight impact would be small. If I get in that situation, I am pretty sure I will CONSIDER putting a doubler there with new skin on top. In addition to the $200 cost of skin replacement, you have all the labor associated with removing rivets and re-reviting the skin, right? Compare that to installing a doubler? Just curious.

I haven't built a thing yet, but every aircraft I know of has structural repairs that aren't to print, and I would expect that I will have to do some of that sort of thing to remain sane. Starting over every time I make a mistake is going to challenge my sanity.
