Nike Goon Build, Part 7, Fin Gluing (Lots Of Fins)

I tend to sand off most of the primer/filler before things are glued together.

Here I'm scraping the glue areas for a better bond.
The fin root scraped area is a little wider than the 3/32" thick fins so the fillet will also stick well.
On some Goons the fins overhand the back of the body tube. On this model it helps with stability.

After one fin was glued on I ran a strip of paper at the top of the root edge so all the fins would be at the same height.

TIP: To get a four finned model that doesn't wobble, glue on three fins. Stand the rocket on those three fins. When gluing on the fourth fin you can (slightly) move that fin up and down the alignment line until all four fin trailing edges make contact with the table top.

That paper strip was slid up to the bottom position of the next row to align the bottom of the smaller fins.

A popsicle stick (craft stick) was clothes pinned on the side of the two fins. This kept both fins in vertical alignment.

Here's how the model looks now, a Goony ready for paint.
