Step 8
� 1. Mark your 6” long tube coupler in the mid-dle with a pen or pencil. Insert the coupler into the main parachute bay tube up to the line and tape it to hold it into place.
� 2. Cut out the “Paper Wrap Marking Guide” from the “Detailed Parts Sheet/Checklist” page of this instruction manual. Wrap the guide around the back end of the main parachute bay tube and tape it into place.
� 3. Carefully drill holes through both tubes using the marked areas on the guide. *Once you’re finished and you’ve removed the guide, cleanly sand the cardboard fuzz away from the holes. Apply a small amount of thin super glue to the recently drilled holes. Allow the glue to dry and then gently sand off any ex-cess glue. This will help clean up the edges and strengthen the holes you made. Then separate the coupler and tube and set them aside.
� 4. Mark the wood parts with a pencil (ex-cept the sled “E” for now) using the example image to the right. *They are already etched on the plywood sheet but marking the shapes themselves with a pencil will serve as a helpful reference during the assembly process.
� 5. Remove the sled Shape “E”, the 2 disks “B1 & B2” and Shape “C” from their plywood sheets. Leave the other pieces in for now. Re-move the small excess pieces inside the slots & holes with a pencil or screwdriver.
� 6. Gently sand both sides of the sled and test fit one of the “B” disks on each end. The disk should slide on and off easily on both ends when completed. Now mark the ends of the sled with a pencil as “E1 & E2”. Use the image example in Step 4.
� 7. Sand the sides of Shape “C” and then place it into the slot on the sled. Make sure the wider end sticks up from the side of the sled that shows the Apogee logo imprint. Once securely in place, dab a small amount of wood glue on the joining pieces along the Non-Apogee side and let dry.
� 8. Insert Metal Weld Nuts “H” into Shape “C” with male ends facing outwards towards Apogee logo imprint. Apply thick super glue to the weld nuts to secure them into place. *Be careful not to get super glue in the threads. Also, you can center the weld nuts by placing the A1 piece on the end while gluing them into place.

� 9. Place the smaller of the disks, “B1” on the “E2” end of the sled and slide it up until it stops. Now apply a small amount of wood glue to the outside surface of the “B1” disk. Then take your larger disk “B2” and quickly slide it up against “B1” (Use the image on the right for reference). Immediately wipe off any glue that oozes out of the pieces on the outside of the disks. Now apply a fillet of wood glue to where the sled meets the disks and let dry.
� 10. For the opposite side of the sled: Re-move the disk shapes “A1 & A2” from the wood kit and remove the excess pieces inside them with a screwdriver or pencil. Place the smaller disk “A1” on the “E1” side of the sled first. Then place the larger disk “A2” on after it. Dab a small amount of wood glue between the 2 disk and then press them together. DO NOT GLUE THESE DISKS TO THE SLED. Once they begin to dry make sure to pull the disks off the end of the sled and set aside for now. *Wipe off any excess glue that oozes out along the outside edges.
� 11. Temporarily insert the assembled sled into the Tube Coupler Part “F” (Included in the Aerotech Kit) and rotate the coupler to align your switch hole with the sled. Then, mark the side/edge of the sled through the hole.
� 12. Remove the sled from the coupler. Align the switch button with the mark you made in the prior step and glue it to the sled using thick super glue. *Be very careful not to glue the switch button itself or the inside of the switch. This may permanently damage the switch and prevent it from working properly.*You may need shorten the wire lengths by cutting and re-stripping the ends.
� 13. Take your Altimeter “N” and align it with the corresponding holes on the Sled “E”. The PerfectFlite StratoLogger CF altimeter will align with the holes spaced farther apart and the Altus Metrum EasyMini altimeter with the holes that are closer together. *This Ebay is large enough to fit almost any altimeter. If you want to use a different one than suggested: Use the hole locations on your altimeters’ circuit board to mark your hole placement and simply drill holes at the marks you made on the sled with a 1/16 drill bit.

� 14. Once your corresponding holes are determined, carefully remove the laser cut holes on the sled with a small screwdriver or pencil. Feel free to rub a small amount of wood glue into the remaining holes that won’t be used to seal them.
� 15. Use your 4-40 tap and drill kit to hand thread the open holes for your altimeter place-ment.
� 16. Tape the Li-Po battery (Or a 9V) to the top of the sled.
� 17. Remove 4 of the wooden washers Part “D” from the plywood sheet. The remainder can be saved and used later if needed. They are provided as extras. *Refer to the “Step 4 Image” on Page 3 for help locating these.
� 18. Carefully place the 4 small wooden washers over the corresponding holes. Then slowly place the altimeter on top of your wooden washers.
� 19. Use your screwdriver to insert the small plastic screws Part “J” into the corner holes on the top of the altimeter and into the threaded holes in the sled assembly. You may need to carefully adjust the washer placement as they can slide around while you insert the screws. NOTE: The screws will not extend from the bottom side of the sled
� 20. Attach the switch wiring to the altimeter (per your altimeter instructions).
� 21. Connect the battery to the altimeter (refer to altimeter instructions for details).

� 22. Trim the exposed wires on the igniters to 1/8th inch. This will prevent any shorts from the exposed wires touching each other. Then attach the Drogue and Main igniters to the terminal block on the altimeter. *Refer to your specific altimeter instructions for further details and MAKE SURE YOUR ALTIMETER IS CONFIGURED TO YOUR PREFERENCES AT THIS POINT, BECAUSE IT WILL BE HARDER TO ACCESS AFTER YOU COMPLETE THE EJECTION CANISTER SETUP.
� 23. Now feed the Main igniter through the hole in the disk on the “E2” side of the sled. Then bend the Drogue/Apogee igniter around the left side of the “C” shape and towards the “E1” side of the sled.
� 24. Slide the coupler tube over the sled assembly. (Use the diagram on the right for ref-erence). The tube will slide over the “B1” part of the disk and butt up against “B2”.
� 25. Take your completed disk piece from Step 10 “A1& A2” and place it over the open end of the sled. Make sure the smaller side of the disk piece goes on first and insert the igniter through the smaller hole.
� 26. Screw both Metal Thumb Screws Part “I” into the open holes on the “E1” part of the sled. Tighten the screws to secure the fit. You may need to rotate the tube around while tightening it in order to align the switch with the open hole on the tube.

*VERY IMPORTANT* MAKE SURE THE SWITCH IS IN THE “EXTENDED/OFF POSITION” BECAUSE YOU WILL NOW BE CONNECTING BLACK POWDER TO THE IGNITERS.
� 27. Take your latex glove and measure it at about 1.25” from the end of the finger tips, then cut 2 of the fingertips off.
� 28. Measure and cut a piece of string at about 7” long. Cut it again in half. This will give you two 3.5” pieces of string, one for each side.
� 29. Fill the inside of each cut finger tip from the glove with 0.5 grams of black powder. *Your rocket may need more or less black powder. Consult your ejection charge calculator.
� 30. Set the Ebay down on a flat surface and then place the Apogee/Drogue igniter through the open end of the finger tip. Attempt to squeeze most the air out of the bottom of the fingertip.
� 31. Wrap the string around the cut finger tip of the glove. Then tie a knot just above the top of the black powder line being sure to leave no air pockets above the powder.
� 32. For the Main igniter setup, repeat steps 30 & 31 above.
� 33. Tie the shock cord from the main body tube of the rocket to the “E1/Apogee” side of the sled. Use a knot that you can untie easily after launch.
� 34. Tie your Kevlar cord to the “E2” end of the Ebay sled. Now place the Ebay into your upper parachute rocket tube (with the “E2” side facing upwards towards the nose cone). Make sure to align the switch hole and rivet holes. The Kevlar cord passes through the tube and ties to the nose cone.
� 35. Place the bottom end of your rivet into the hole through your rocket and press it in. Then place the top end of the rivet all the way into the bottom piece. This will lock the Ebay into place. Repeat this process for the remain-ing two rivets. *To remove the rivet simply grab the top piece and pull.
� 36. Take the main parachute bay tube and slide your completed Ebay into the end.
� 37. Congratulations, the Ebay assembly is complete and ready to be placed into your rocket!
