Enerjet by Aerotech Strong Arm Build, Part 14, Launch Lug Fit & Fillets

While the fit of the vane sides were pretty good, the edges could still use a fillet.
I used Titebond Quick and Thick with a smaller Elmer's glue bottle nozzle. 

TIP: On a long fillet like this, it's easier to glue and smooth about half of the length, then do the upper half. Too much excess glue can pool under your finger when smoothing out a long fillet. 


GOTCHA: The coupler end inside the upper slot prevents the front of the launch lug from fully seating.

I filed down the front half of the positioning tab to fit over the coupler.






Beacon Fabri-Tac was used to glue the launch lugs in position.

A piece of masking tape held it down while the glue sets up.


I'll be on vacation for the next five days, there may not be posts while I'm away.

  1. I'm impressed you were able to get the Quick and Thick to flow through that nozzle.

    Lately my preferred approach is to use the Quick and Thick bottle and just cover most of it with blue tape, e.g.: https://cdn.imagearchive.com/rocketryforum/data/attachments/281/281327-81ad3c00cf8c4d06826f4140d502386c.jpg

    1. Hi Neil,
      Before using the Quick and Thick I pull off the orange nozzle, clear and clean it out with water and a skewer.
