Searchable or Indexed High Power Rocketry Magazine Articles?

[pyrobob]

I'm pretty sure I own every issue of High Power Rocketry magazine and need to locate a certain article. Trouble is that there must be at least 30 mags that I'd rather not sift through. Long story short, has anyone compiled a list of articles appearing in HPR? Did some basic Google searches and checked Tripoli's website but no joy.

Thanks in advance!

None that I know of, but if you say what you’re looking for, someone will come up with it.

Good idea . Pretty sure it was an article regarding the use of styrofoam as shear pins. Pretty certain it was a Vegas group going by "NASSA".

Styrene rod ,I think is what you are talking about. Early on I used them. Common back in the day.
Come in 12in length. Insert into holes and trim flush. They work great just a bit of a pain compared to shear pin/screws.
Was much easier to find at RC shops before shear pins were readily available.

How ever someone may have used styrofoam, ya never know.

That's what I started out using; Styrene rod. Worked well, and just nipped off with a set of side cutters.

Yeah, I still have styrene rods in my old range box. One thing I found out the hard way was that it slowly shears under compression with less force than you would expect. I have loaded recovery gear and pinned the bay only to watch the nosecone creep back out and the rods shear. Nylon is much better.
