Default RE: Molding a Dirty Bridy 60 Fuselage

Finally had some time to post, and Man! I sure wish Frequent Flyer would post pics of his molding process and the layup process. He‘s out of control.
I digress, back to the stab.
As beautiful as the vertical stabilizer was I learned a valuable lesson about filler material and balsa and had to trash it. Bummer!
This is what happened –
After finishing the vertical stabilizer I test fitted it to the fuse and then used a laser alignment tool to check that the top was straight. I tacked 2 pieces of hardwood to the sides of the stab to align it to the back of thefuse and I was off an 1/8 to 3/16 of an inch on the top to one side. I must have sanded too much off that side when rounding the top. So I figured no problem, I’ll just use some bondo to build it back up. Worked great, at least that’s what I thought until the next day.
It turns out the bondo shrank the balsa sheeting between the ribs and concaved the space between. Lesson learned, I should have glassed it first than used the bondo to straighten it out.
