Performance Formula 75 question

[markkoelsch]

Hello all,

A while back I purchased a Formula 75 before they were setup for HED. So, I purchased a new, longer coupler to make is HED. The question is this- the nose one is one of the filament wound cones with the epoxy tip- there is no threaded insert in the tip. So, how do I anchor to this nosecone?

I was thinking possibly embedding a 1/4" 20 nut is epoxy and Kevlar pulp.

Thoughts?

You can mount a small steel angle bracket with a 1/4 inch hole (available at big box stores) high inside the nose cone by initially using JB weld and subsequently covering with 2 layers of fiber glass cloth. The 1/4 inch hole in the angle bracket can have a short screw/eye nut in place in which to attach your kevlar cord that in turn will attach to the HED main chute laundry.

Good luck,

Get a 29mm or 38mm G-10 bulkplate.
Drill hole in center of BP and install a 3/16" eye-bolt.
Tie your cord on eye-bolt and lower it into the NC
Tap it in snug and level with a wooden dowel
Mix up your favorite expoxy and pour a layer in over the bulk plate, swirl it around a little bit to get some epoxy on the side walls of NC above the BP also.

A more down and dirty way I've done it also is to just tie a knot on the end of a piece of Kevlar cord, drop it into the NC till it touches the tip, mix up some epoxy and pour a plug over it.

I just epoxied the end of the harness to the side of the NC, high enough to miss the coupler. After it dried, I took it outside and swung it around like crazy to make sure it held. Done.
