Nerf LMG (Light Machine Gun) (unfinished)

thingiverse

Human: *NOTE* This is a project that I am currently unable to complete, due to insufficient time and funds. I wanted to post this here in case anyone likes it or shows interest in it. Here's a brief rundown of what this massive Nerf gun is all about: * Nearly 1.1 meters long * Belt fed loading system (inspired by the Nerf Vulcan) * Chambers both Mega darts and normal sized Nerf darts * Unsure on rate of fire as of right now * Fully automatic * Powered by a 7Ah 12V sealed lead acid battery (overkill I know, but I wanted this thing to last a while before having to recharge) * Uses a system of gears, worm gears, and chains to slide the action * Magnetic sight mount allows for easy and fast customization of sight system * Unfinished (I haven't made mirrors of the outer shell components yet, and I'm not sure how well it will work once a working prototype is built) Here are some links to the parts that this Nerf gun is built around: Main Firing Springs (20mm OD, with 1.4 mm wire diameter): https://www.ebay.com/itm/Wire-Dia-1-2-2-0mm-OD-8-35mm-L-300mm-11-8-Helical-Compression-Spring-Select/222445273264?hash=item33cac580b0:m:mwTGmIjP_HGZwRcG8fNlJtw Battery Connectors: https://www.ebay.com/itm/2-pcs-HXT-4mm-to-Traxxas-Female-Male-Connector-RC-battery-adapter-12-AWG-Wire/152521949012?epid=907137315&hash=item2383043f54:g:tfkAAOSwJ4hY~NOX 4 Pin Relay: https://www.amazon.com/gp/product/B072236SX2/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 12V Lead Acid Battery: https://www.amazon.com/gp/product/B003S1RQ2S/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1 Assorted M3 Screws/Nuts/Washers: https://www.amazon.com/gp/product/B06XYLKP5Y/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 Assorted Small Springs: https://www.amazon.com/gp/product/B000K7M36W/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 12V DC Motor: https://www.amazon.com/gp/product/B0721T1PXQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Motor Bracket and Hex Coupling (coupling and bracket are both needed for assembly of nerf gun): https://www.amazon.com/gp/product/B00TK0X03U/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Small Magnets: https://www.amazon.com/Fridge-Magnets-Refrigerator-Science-Crafts/dp/B01NCKNB9M/ref=sr_1_3?ie=UTF8&qid=1513270832&sr=8-3&keywords=small+fridge+magnets
