I'm building an LOC DoorKnob. I've always liked short stubby rockets. I built this LOC Warlok about 15 years ago and it was always fun to fly.
For the DoorKnob I'm building the airframe completely stock. I used Titebond to glue the fins and fin tabs in place. I decided to use 30 minute epoxy to glue the motor mount in place mainly because it would give me a little time to adjust the placement of the parts before the glue grabbed. All that is left on the airframe is to add a motor retainer and paint.
I want to try dual deployment on this rocket but I don't want to add any more length to it so I'm going to try Head End Deployment and a cable cutter. The altimeter bay will be built into the nose cone. Instead of cutting the entire bottom out of the nose cone I'm going to cut a 54mm hole in the bottom and glue a 4.5" centering ring inside. I'll have to cut a 4.5" by .25" slot to get the ring inside the cone. Six 10-32 screws will clamp the plastic bottom of the shoulder between the centering ring and a bulk plate. The AV Bay will be glued to the bulk plate similar to the method that John Coker documented on his web site.
I've ordered the centering rings from Nat at UpscaleCNC. I emailed the file to him yesterday and he already had them cut this morning. I like dealing with vendors that work at my pace.
