Tools Update on my Website
In addition to the Rocket Database download and my online Centering Ring Generator, I've added a new Shroud Calculator. It's like others I've seen online (after all, the math is the math) but has a few added features.
First, when you are filling in the small and large tube sizes, you can choose body tube types (both Estes and Centuri/Semroc sizes are available) from handy pulldowns... no more pulling out the catalog or trying to find the numbers online, then transcribing them by hand. Next, results are presented three ways: As decimal inches (to three places), fractional inches (rounded to 32nds) and millimeters (rounded up). I don't know about you, but I don't have a ruler marked in decimal inches; either 32nds of an inch or millimeters are better choices for me. http://rocketry.newcenturycomputers.net/tools.html

Sounds cool. I'll have to look at it tonight.
I have a ruler in 1/10ths. It's pretty handy. It's a triangular engineering/architectural ruler similar to this one. |

Ah. But 10ths of inches are less accurate than either millimeters or 32nds of inches; and you can fudge 32nds on a ruler marked in 16ths.
The transitions I made for the Celestial Navigator were computed using this tool, and they came out just a hair big; but this is fine, as I'd rather cut one down a bit than have one that's too small and be unable to fix it.

The Shroud Calculator now has a template generator. It's not terribly well tested as yet; feel free to try it out and then complain here if it doesn't work for you.
Also, I've upgraded the Centering Ring Generator just a bit, so that it shows centerpoints for all circles. I think they may be off-center about 1/150" (or perhaps 1/300"); I'm still working on it.
