Wasting no time in getting started on the next build. I've said many times that I'm a big fan of some of Estes early rocket designs but I've always though they were simply too small. Designs like the Hawkeye, Yankee, Ninja, Wizard etc. are all great, simply, clean designs that deserve to be upscaled. For this build I'm going to put together another of my favorite simple Estes designs, the Laser # 1938 but this time it's going to be a 2.5" version.
Parts List.
- Estes 2.5" Pro Series nose cone.
- Estes 2.5" Pro Series tube. These is a full length tube at 15.5"
- Estes 2.5" Pro Series tube cut to 13.8"
- BMS 29mm motor tube cut to 11.5"
- Estes 2.5" Pro Series coupler 4.0" long.
- 1/4" Launch Lug.
- 29mm motor block.
- Baffle plates cut form .125" ply.
- Screw eye.
- Bad Boy Rocketry 2.5"x29mm centering rings.
- .125" plywood fins custom cut by Dragon Rocketry.
- Estes 29mm motor retainer.
Starting off this build with marking and slotting the lower body tube. The tube was marked and .125" slots were cut to allow the TTW fin tabs.
Next I began working on the motor mount. The motor tube has had the outer layer removed from the areas here the fins and rings will attach. The surface was then sanded with 100 grit to open up the fibers.
The upper centering ring was attached using T-88 epoxy and set aside to dry.
With the motor mount drying, I began work on the baffle. The baffle is a four plate design made from .125" plywood. The upper plate has a small reinforcement piece on the underside where the screw eye will attach. Each plate will be spaced 1 inch apart and attached using epoxy.
Going to let that cure for a few hours.
