Estes Sprint XL #7224 Build, Part 7, Fin Gluing

With the lugs glued on the fin marking guide is wrapped. Line up the LL line with the lugs already in place. The engine mount hasn't been glued in place yet.

TIP: With the tail cone removed, extend the fin line over the lip end of the tube.
With the fin even with the end of the tube the gluing line will be completely covered by the fin. With that little tick mark on the body tube edge you have something to center the fin on.

Wow, flashback to 1972 - only bigger.

The fins were initially glued on with Titebond II.
A fillet of Titebond II followed, then a final fillet with Titebond M&TG. Or as its now called, Titebond No Run No Drip.
