Picture of nerf vortex pyragon powerup
i took apart my nerf disk gun and changed the spring position so that it would be more pretentioned and thus have more force.

Step 1:

Picture of
first take out the shown screws
the black box next to the gun is the end cap for the stock attachment point
important to note that the ones indicated in pic 2 are longer than most
pic 3 is of all the types of screw taken out in this instructable and the # of each
note that the very short and the silver screws don't come out till later

Step 2:

Picture of
the next step is to remove the caseing.
first pry as shown in pic 1
then pull back as shown in pics 2 and 3
pic 4 and 5 show the pin on the tactical rail.
it is worth noteing because it has a tendancy to fly off on it's own
whatchfor and prevent this

Step 3:

Picture of
now remove internal screws
these are the very short ones and the silver one shown in step 1 pic 3

Step 4:

Picture of
now you need to pull open the champer that houses the spring.
it may seem likeyou are breaking it but dont worry
you then remove the central pin and rubber cushin

Step 5:

Picture of
now you remove the firing arm
it must be turned around fully to remove it

Step 6:

Picture of
now wrap the string around the end of the spring and pull it back
then place the firing arm back in such that the spring is pushing on it
this is different from the initial state in that the spring is now wound more

Step 7:

Picture of
now replace the pin that holds together the spring and arm as well as the rubber cushin

Step 8:

Picture of
now close the central chamber
it will probably stick but just keep trying and it will eventualy fall into place
i have included pics of some of the places to particularly watch for catching

Step 9:

Picture of
replace screws
Thanks for the write up, that came in handy. I would also suggest that anyone doing this should file down or dremel off the little white plastic lip/ring that has to be slid out in step 2 that makes it so hard to get the 2 halves apart and back together.

You ought to use a "finished" image as your "intro" image.
