NCR has an old home made theodolite for measuring rocket altitudes by means of a two-station triangulation. The utility for such a device has declined with the widespread use of on-board altimeters, even for NAR contests. Joe has indicated that as contest manager, I no longer need to store this. Anyone want it?
I'll salvage the yellow plastic toolbox it comes in as it may be useful for another NCR need.

Hi Chad,
yes, I will take it! I can imagine that it will provide some hands-on experiences for my middle schoolers. Thanks! I am going to the Cinzetti dinner tonight and getting out to the 3/1 launch.
OK Dave, it's yours.
I won't be able to make the 3/1 launch (anyone in FoCo environs going that I could transfer the equipment too?). So we may have to plan on the April launch or an ad-hoc rendezvous.

Chad - I'm in Fort Collins and going to the 3-1 launch (assuming the weather gods don't snow on our parade again)... I can facilitate the transfer. PM me when/where to pick it up.
Dave - if the transfer happens, I'll be in a white Toyota Tacoma pickup...
Are you guys talking about one of those short isosceles triangles with the round thing in the middle with degree marks around that round thing and a circular bubble level on it? And you would take two of them or three of them and establish 300' baselines from the launch pads to help figure the altitude of a given flight using trig? Never used them. I do not even know what they look like. Mine were always mounted on a cheap used surveyors tripod, and then I would make my own kind of sextant using tubing (like a BT-50 with plastic wrapped around it to make it tougher, and a couple of pieces of thread in each end made into cross hairs to help increase the accuracy) and three protractors, a yoke, and build something to mount on top of the tripod, to help determine angles on a known baseline. WOW, this is bringing back a whole lot of bad memories that I had been fortunate enough to forget for decades. 🙄
I am hoping Bear, that it is somewhat like that! I think that it is pretty important for kids to learn the math first before they go to the instant gratification of simply seeing the readouts from electronic altimeters. Good time to do it the hard way....
Maybe some slide rules thrown in will complete the lesson!
I am planning to be at the launch, but I am also a fair weather flyer; don't want to fight the cold nor the wind. Today was beautiful at work, just a little to breezy at times.
I understand. I will not be there, again. I will be working the gun show in Laramie this weekend. Gold and silver bullion, IRA conversions, knife sharpeners, and hopefully some ammo will be sold. No theodolites, though. Most people don't know what I am talking about! 🙄
