Semroc Snake Jumper Build, Part 5, Fin Gluing


Card stock fins are thinner than balsa and have a thinner root edge for gluing.
Just like the old Centuri kit, "gusset" reinforcements are used. The gluing position is lightly burnt into the side fins.
You can go ahead and fillet the gussets on the bottom, rounded side.


The long top fin and cockpit piece is easy to glue on crooked. Be sure it is straight before gluing. I used my aluminum angle to double check it down it's length.




The launch lug is sandwiched and hidden between the "wheels". The wheel halves glue on either side.


Before applying glue, do a dry fit and mark where the glue contact points are. Use less glue and there will be less to clean up.



Looking down from the front, double check to be sure the wheel halves are straight and parallel.
