I'll be using a Giant Leap Rocketry "Hardpoint" Recovery System Anchor in my 54mm minimum diameter rocket. These are very similar to minimum diameter anchors made for motor casings (without motor ejection) only these are vented to allow ejection gases to pass through them. I'll be using motor ejection only for my rocket.
The Hardpoint is made from one-piece aircraft aluminum. I have replaced the included eyebolt with a 1/4"-20 X 2" Forged eyebolt for greater strength. My question regards the mounting.
I'm considering using screws drilled through the fiberglass airframe and and the Hardpoint for attachment rather than JB Weld epoxy. This would allow me to move the location of the Hardpoint up and down on the rocket depending on which motor I'm flying, or to remove it entirely for use in another rocket. Plus i think the mechanical connection would be stronger than the Epoxy, right?
I was thinking three #4 stainless steel screws, and using a drill press to ensure the alignment of the screws.
Am I on the right track here, or is there a better option? Always grateful for the advice and expertise on this forum.
