Nerf Vulcan Modification Project

Step 8: That's it, for now.

For now, I'm done modding my Vulcan, but there are plenty more mods I'm planning.

I will update this Instructable with future mods that I do!

Future mod list:

• Round Counter
• Extended belt -- maybe not, this would put too much stress on the belt feeder (if the belt was hanging)
• Rechargeable battery - possibly an old laptop batt?
• Better ammo box
• Better belt feed - see next item
• Metal components (and CAD Drawings)
• Stefans (requires belt post removal...)
• Rewiring

found a motor that would be almost perfect for an upgrade :)  http://www.allelectronics.com/make-a-store/item/DCM-345/12-24_VDC_MOTOR/-/1.html

awesome project  i just though id imput some wisdom.

motor

The stock motor is 32mm long, 27.6mm in diameter, and has a shaft diameter of 2.4mm.
To replace the motor with a better one u need  the size of it.
380 size is generally 28mm dia. 35-40mm length.
while 370 is 24mm dia. 35-40mm length.

gears

to strengthen the gearing and things use delrin. delrin is a composite plastic that is stronger than average placic without being to heavy.

batteries
ni-mh are probably the best choice of battery for this you can get them for rc cars. Li-po is the other option it is lighter and more powerful, but it is much more expensive and can explode if u dont use it right.

All the things listed are designed for application with rc vehicles.

Thanks!

do not have access to any delrin, but i do have a good amount of steel, and am quire proficient on a mill i have made at least a dozen gears for various projects without using a tooth-cutter... its tricky, but possible.

i also have some old laptop batteries... (lipo) that should work quite nicely.

hey what do you think is the hardest nerf gun to mod is

[travis_bickle]

old laptop batteries are lithium-ion, not lipo :)

[Zinventor]

Correction: SOME old laptop batteries ale Li-Ion, SOME are Li-Polymer... the ones that was planning on using were Li-Poly... However, I've kinda abandoned the project for now, as I'm in college and have limited time...

my dad and i have been unable to make nice gears using a cnc mill. could you tell me how you do it?

[Zinventor]

All I can tell you is it's a pain in the A$$, and will likely take a lot of time... The best way (other than using a gearcutter) is to mount your round-stock on an indexer (like a lathe jaw, but lets you turn the part in very specific amounts) and, using a router bit (with the pitch you want for the teeth), carve out each individual tooth...

It's a long and laborious process, longer if you need alot of teeth, and damn near impossible without an indexer... I suppose you could do it with just a vice, but getting it lined up perfectly each time would be a pain...

i saw a vid on youtube where the guy who modded the vulcan used 2 rc car batteries, but the description said the gun kinda melted afterwards.

[mean machine]

yes they melt coz the stock engineand gears arnt ment to be used at that speed and there is just TOO much stress on the gun

[timdiveetz]

I'd say just to make it lighter :/ it has good distance and power, it's just a workout to lug it around all day.

 just chop off the front barrel

I'm working on that now, but i actually ended up reversing the mod to remove the air restrictor, since it didn't increase the range as much as i had hoped (Only about a 3' increase in distance). the rechargeable battery should be lighter, so that should help... i'm still planning the round counter, but the belt feed mechanism jams really easily. hopefully, metal components will fix that. (however, it'll be alot heavier.) -Z
