No I know what it means, I was laughing at seeing it used.
I got some stickers from Stickershock that have my name and phone number. It also says reward and has my NAR and TRA numbers. One goes on every rocket. I also made a sticker that has the rocket length, weight, what chute to use and what size motor mount. It is there so I can fill out the flight card without looking in a book or guessing.Put your name and contact information in and/or on your rocket. (That's another one I'm guilty of not doing.)
Put someone else's name and number in your rocket. Hopefully you won't be blamed for your Mylar streamer tripping out an entire substation (they can keep it, I'll be over here whistling suspiciously).Put your name and contact information in and/or on your rocket. (That's another one I'm guilty of not doing.)
See below.Smile, be polite. Advise is free, and freely offered. Accept it, and say thank you.
Or just learn from them how to (see above) smile and listen politely. Sometimes, free advice is worth what you pay. Sometimes it's worth a heck of a lot more. Listen, consider, but do not abdicate either the right or your responsibility to make your own decisions.There is always someone more: Smarter / Skilled / Educated / Opiniated / Armed / etc... Learn from them: either what to do / not to do.
I often say: “This might sound like a dumb question, but I am going to ask it anyways because I want to learn”And I should also add:
"I don't know" is a perfectly valid answer. (unlike what we are taught in school..) I'm teaching this to a few student teams.. If you don't know, you don't know... Don't guess or make something up!
Actually, aluminum hex rod stock is cheaper than round. Like, 35% cheaper or more, depending on supplier.I assume because manufacturing round things is easier than other shapes. Simple as that. I assume.
Come to think of it, blades that stick out wider than the handle would have prevented the problem to begin with.
Well, that would make "manufacturing round things... easier than other shapes", would it not? Knerling hex stock is also more difficult (to say the least) and therefore more costly.My guess is the extra time required to machine one end before cutting the threading for the grip/blade retaining ring gets costly.
I misunderstood what you meant. Manufacturing the round material results in a more expensive product was my point. Working with said material, however, is cheaper.Well, that would make "manufacturing round things... easier than other shapes", would it not? Knerling hex stock is also more difficult (to say the least) and therefore more costly.
I use Happy Hands anytime I use epoxy or CA and sometimes when I paint. It's a skin barrier cream you put on your hands. The gooey stuff sticks to it and not your skin. Washes off with soap and water. Apogee carries it. The stuff is magic....91% isopropyl alcohol (isopropanol, rubbing alcohol) and a paper towel will remove epoxy from your skin if the stuff hasn't gotten past the chewing-gum stage. Several applications and rubbing/scraping may be necessary.
NEVER use "denatured alcohol" from the big-box store on skin. I thought that the alcohol had 5% denaturant added., as that was what we always used in the lab. I was surprised to learn that it can contain considerably higher concentrations. If the denaturant is methanol, you may be in for a bad time. It's toxic and can be absorbed through the skin...
+1When adding clay nose weight inside a plastic nose cone for an LP build, don't struggle with a dowel to tamp the clay into place. Instead, use a dowel just to get a very rough tamp. Then place the nose cone, tip down, in a water glass, preferably with a diameter just a little greater than the nose cone's; whatever you've got will do. Then fill the glass with boiling water. The clay will soften enough to flow, filling the tip of the cone neatly and completely. If it's a lot of clay in a big cone, you may have to change the water as it cools off.
I like these little glasses that come with chocolate Mole in them.

Shrimp cocktail glasses just work as well.
