Re: Experiments in OBT An accelerometer is a sensor that measures changes in speed (and direction). Pretty much like it sounds. They are useful in vibration analysis. Unlike strain gauges, they usually have significant mass compared to a strain gauge, thus, if attached to a barrel, they...

I have sold under a lucky star and have been granted access to some very nice high speed data acquisition equipment for the summer. My thoughts are to design some experiments around OBT theory. My initial plan is to instrument the chamber and muzzle with strain gauges to detect the travel of...

Re: Hart, Kreiger or Bartlein? I have many Hart's and Kreigers. Both manufacturer's barrels provide results beyond my abilities to discern the difference... In fact, I have two receivers in each shop as I type. I have to tell you, I haven't lost a minute's sleep wondering if I should have...

Re: Help with manually calculating DA Jo, Just to warn you, calculating DA is no simple task. It's also beyond one post, so I am going to refer you to the below links which should get you going. The NOAA paper is probably better. As you get in to it, you'll see that you can make your...
