Maxi Brute V-2 Fillets

[timster68]

I am seeing where my Boyce Aerospace V-2 fins on my Maxi Brute V-2 need some fillets to fill in the gap a bit.
I have AeroPoxy Light and White Squadron Putty now. Are either of these the best solution or is there better option?

Perhaps dab in tiny amounts of epoxy to fill the gap, wipe away excess with alcohol on a cotton ball, cure, then putty?

I found this thread: Revisiting the Estes Maxi Brute V-2... | The Rocketry Forum
This sounds like the solution.

If it were me I would use Hysol 9462. 2 part epoxy, 24 hr cure time. I think it is very good. Have used it for years. Will not drip or run. I would put it in a syringe and lay a bead in the joint, then run my finger along bead to fill and feather it out. It is white in color, so painting is easy.

What type of adhesive did you attach them with?

Like David Schwantz I am a fan of Hysol 9462. Put tape on fin and body tube. Run bead of glue using long mixing tube (better mixing than short ones). Smooth with cake fondant tool. Remove tape right away.

I will NEVER use the short tubes. I found that they do not give enough "length" for a good mix.

What type of adhesive did you attach them with?

I used J-B Weld Plastic Bonder. Boyce Aerospace recommended it to attach their fins.

I’m making some progress with the Tamiya putty.

Spit is a wonderful thing. Try spitting on your finger and wipe the putty to from a smooth fillet.
