Theres alot of room for customization.
Write mode commencing
Adhesive of choice (I usd Gorilla Glue)
Metal L Bracket or something else that could be a trigger
O-ring (not sure which #) it should fit around 1" PVC snugly
1/2" PVC endcap
1/2" PVC T-joint
spring of choice (make sure it fits around 1/2" PVC, I used an ACE# 49 *not pictured)
Can be achieved by a dremel, a drill, and a hacksaw
Begin with 16.5 inches of 1/5" PVC
and cut a 1.1x6" rectangle aproximatley 5.75 inches away from the front of the blaster
Then drill a hole 2.8 inches on the bottom of the 1.5"PVC on the backside, also make an indentation 2" away from the back
Here comes the plunger/piston assembly
the main part is 8.65" of 1" PVC, put the o-ring towards the front as pictured and I just glued it on (It stayed even when dry firing with no lube)
next cut a .5x.75 hole 1.25" away from the back
now fit 5.5' of 1/2' PVC into to .5" of 3/4" PVC and ut it so that the 3/4' is flush with the end of the 1/2" PVC and fits in flush with the 1" PVC also drill a holw for your choice screw and counterbore it so the screw is flush with the plunger, I just attacked with the drill bit piece of my dremel
Now dremel down the area before the slot so it makes a ramp
Onto the handle
I used 3/4" PVC for the part that you hold, it uses your basic clothespin trigger setup I used a section of 1.5" PVC for the top piece
heres some detail shots
Attach your handle to the back ofthe 1.5" PVC like so
Now we need a bushing at the back of the blaster, you could buy a 1.5" to .5" PVC bushing but I didnt feel like doing that so I used 1.25" with 1' inside, with 3/4"Pvc inside of each other
Make sure its not longer than .75"
Dremel out about .5" of the back of the 1.5"PVC so it will let the 1.25" fit inside snugly (mine wouldnt fit)
Place the homemade bushing in the back (a little stuck out)and drill a hole for the choice size screw on both sides
Make sure that the screws for the bushing dont extend past where the 3/4" PVC is, otherwise it will block the plunger spring guide
Get your T-joint and cut the bottom off
Place it 1.85" away from the back of the plunger which should be inserted into the 1.5" PVC
and drill two hole on both sides of the t-joint
Make sure that the screws that you use for the t-joint have screw heads that extrude to the same thickness of the 1.5' PVC that way the priming handle wont go to far forward or backwards
Put a 1/2" PVC handle on there
heres a homemade bushing I made for the front end of the 1.5" PVC, its 1"PVC wrapped in electrical tape with an O-ring. This will allow me to fit n 1/2' PVC couplers, wyes, and other attachments
Theres a brand new MP SNAP for ya.
Here are the ranges with an ACE #49 spring
So an average of 95'
