**E178: Lab 5 Final Assembly Level 2** |[home](../index.md.html)|[syllabus](../syllabus.md.html)|[assignments](../assignments.md.html)|[labs](../labs.md.html)|[final project](../finalproject.md.html)|[flight data](../FlightData.md.html)|[getting certified](../RocketryCertification.md.html)| # The LOC Precision Dual Deployment Vulcanite Kit Detailed assembly instructions are at [Vulcanite DD Assembly Instructions](../VulcaniteDDRocketAssembly.md.html). General modifications to Vulcanite construction for a Level 2 flight are outlined in [this location](../RocketryCertification.md.html#constructionhints/locprecisionvulcanite). These recommendations have already been incorporated in the assmbly instructions. The manufacturer's instructions, which should _not_ be followed, are available for reference [here](https://locprecision.com/wp-content/uploads/PK-52_Vulcanite_H76.pdf). Some more details, including an outdated the list of supplies is on the [Flight Hardware](../FlightHardware.md.html) page. # Final Assembly. Follow the steps in the [Vulcanite DD Assembly Instructions](../VulcaniteDDRocketAssembly.md.html) - [Epoxy in the motor-mount assembly](../VulcaniteDDRocketAssembly.md.html#finalassembly/insertingthemotormountassembly). - [Mark the launch lug centering line](../VulcaniteDDRocketAssembly.md.html#finalassembly/launchlugcenteringlinemarking). - [Attach and fillet the fins](../VulcaniteDDRocketAssembly.md.html#finalassembly/fins). - [Attach the rail guides](../VulcaniteDDRocketAssembly.md.html#finalassembly/railguides). - [Attach the motor retainer](../VulcaniteDDRocketAssembly.md.html#finalassembly/motorretainer). - [Attach the chute protectors and the parachutes](../VulcaniteDDRocketAssembly.md.html#finalassembly/chuteprotectorsandparachutes). - [Mark the Center of Pressure and label your rocket](../VulcaniteDDRocketAssembly.md.html#finalassembly/paintingandmarking). - [Populate the GPS Support](../VulcaniteDDRocketAssembly.md.html#finalassembly/populatingthegpssupport) - [Populate the Avionics Bay](../VulcaniteDDRocketAssembly.md.html#finalassembly/populatingtheavionicsbay) !!! warning You **MUST** label the center of pressure of your rocket with a center-of-pressure symbol, which is a circle with a dot in the middle, $\odot$. Use either a hand drawn bullseye, or a waterslide decal CP symbol. If you want or need to cut your own plywood parts for the GPS Bay and/or the Avionics Bay out of 3 mm plywood, the PDF files for the laser-cut parts are in [this archive](../SolidWorks/VulcaniteDD/PartsToCut2024.zip). If you want to modify the parts, the Solidworks parts files are in [this archive](../SolidWorks/VulcaniteDD/VulcaniteGPSSupportParts.zip) and in [this archive](../SolidWorks/VulcaniteDD/VulcaniteAvionicsBayParts.zip). The files have been parametrically designed, so that you can change the parameters to fit your rocket if your measurements differ. More explicit instructions for the parts are [here](../SolidWorks/Weasel/CuttingTheWeaselAvionicsBayParts.md.html). The finished rocket will be assessed according to the following rubric: Score | Description ------|------------ 5 | Components in the correct places and square. Epoxy joints neat and reasonably smooth. Fillet large enough, smooth, and with sharp lines. All joints mechanically sound. CP labeled correctly. Name & phone number on both payload and body tubes. 4 | Components more-or-less in the correct places and more-or-less square. Epoxy joints not too messy. Fillet almost large enough, fairly smooth, and with fairly sharp lines. Most joints mechanically sound. 3 | Some components in the wrong place and/or noticeably tilted. Epoxy joints moderately sloppy possibly with gaps. Fillet almost large enough, not smooth, and without sharp lines. Some joints mechanically sound. 2 | Most components in the wrong place and/or noticeably tilted. Epoxy joints sloppy possibly with gaps, some epoxy drips. Fillet irregular, not smooth, and without sharp lines. Few joints mechanically sound. 1 | Serious questions about component placement. Epoxy joints really poor, possibly with gaps, frequent epoxy drips. Fillet very irregular, rough or wavey, and hardly defined. Serious questions about mechanical integrity. # Avionics Bay and GPS Support You will want to test your Avionics and GPS prior to launch. The assembly instructions told you where most of the parts go, but they didn't describe the final wiring. Check with Prof. Spjut on how to get your rocket fully prepped for launch. See the [Vulcanite Avionics Test](../VulcaniteAvionicsTest.md.html) page for avionics testing. # What to Turn In Demonstrate your completed DD Vulcanite to Prof. Spjut for inspection.
