Hi everyone,
A few days ago I received my new Jolly Logic AltimeterThree (JLAT). Just to begin experimenting, I plan to use the JLAT on some low-power rockets that I have -- namely, an Estes Drifter and an Estes Firestorm.
I understand that, for ventilation purposes, I need to make at least three of four holes in the airframe evenly spaced around, and that each hole should have a diameter of approximately 2.0 to 3.5 mm.
Making the holes should not present a problem using a standard drill. As I further understand it, the holes themselves are sufficient to provide ventilation. To strengthen the holes, however, and to make them more attractive, I should attach eyelets.
Here's the problem. The holes need to start a bit more than 25 mm aft of the front end of the airframe. To get the underside of the eyelets to spread out, the instructions say to use either a Dritz #104T tool or a 574 pliers kit. But these devices will only reach in about 25 mm -- not deep enough into the airframe for me use the tools.
Does anyone have any advice, please?
Thank you.
Stanley
