cut out 3/4 pieces.

90 minutes

cut out all 3/4 pieces.

i use a 1/4 bit and cut on the outside of the path.

i switch to a 1/8 bit to mark the holes and hand drill them. my 1/8th inch bit is only 3/8’s of a inch long.


cut out 3/8th pieces.

16 minutes

move the 3/4 inch pieces to the side and bring the 3/8th pieces into the cut area. then carve them out.(need both plates)

cut out with a 1/8th inch bit


cut the plastic.

6 minutes

move the 3/8th pieces to the side and bring the plastic pieces into the cut area. then carve with a 1/8th inch bit

plastic i use is a cutting board from walmart. its right under 3/8th thick and works for all of the rubberband guns i make.



10 minutes

sand the burs and thin the trigger/mag down a little so it moves freely when assembled.

the plastic t needs a 45 cut in the tip of it. i just push it against my belt sander. no accuracy needed. just has to fit inside the star wheel to make it single fire.

round the edges of the star a bit so it doesnt cut the rubber bands.



10 minutes

7 screws are 1/2 inch long on each side
the chicago screws are 1 1/4 long cannot select length in parts list.

the 3 holes for the chicago screws need to be adjusted to fit the post size you can find.

top center of the trigger needs drilled so a screw can go threw the plastic T to make select fire work.
keep this only finger tight so it can spin so it can go full auto or single fire.

if the mag is larger it fires at a slower rate. smaller makes it fire faster.



10 minutes

google rubber band carbine and there are youtube videos of how to make it.

before using the cnc it takes me about 1 hour to make drill sand assemble tweak and so on to get one going.

now i can cut enough out to make it so i can have enough pieces cut so i cannot keep up with the cnc cutting on assembly.


have fun

999 minutes

have fun mowing down card houses and all sorts of things. get around 24 bands per load.

i have done 32 on 1/4 inch side plates and it snapped the plates. 24 is where i would stop. it can hold more but be warned!
