Booster 55 Rocket Build, Part 4, Launch Lug and Standoff
The rear engine locking ring is wider than the BT-55 above it.
The 3/16" launch lug will require a standoff so the launch rod will clear it. This rocket can use 24mm engines so I used the larger 3/16" lug.
I used a small dowel for the standoff.
It reminds me of the old Estes C-Rail standoffs. (The old-timers will know what I mean.)
The bottom of the dowel was sanded flat for a little more gluing area on the tube.
The tube and nose cone were already hit with filler/primer.
I scraped off the primer where the lug standoff will be glued.
TIP: Try scraping with the back side of the knife blade. You won't dull the sharp cutting side.
Here's the finished lug with standoff.
Fillets of Titebond No-Run, No-Drip glue followed.
