this is the part that will be driven by the motor to make the chain go round and round
on the drivechain at the back it has 13 blue rings
not putting list because you can make this by eye

i used the knex motor from the 30 model pack but i think any motor can fit in

I just got done building it. small power. Takes an age to reload fully auto. The engine is really weird to. It couldn't work with my erector motor or a regular rectangle one. I finally found a motor that would work but it goes really slow I will try to Improvise and mod because reloading takes forever.

making motor faster the bullets should shoot about at least 3 fps now 3 bullets per second.

You have so great reviews I am going to build your gun, however I have a erector motor which spins way faster then a knex motor. I will heavily mod this design thank you for the original design. Will post win finished, no instructions, slideshow

r there any mgs that dont use a motor just a crank

J Moneyman (author)T.E.A.2009-02-21

yes. there is a knex mg that you crank. but it shoots bbs and airsoft bullets.

mythbusterma (author)T.E.A.2008-10-18

not only that but you should just take off the motor and add your own crank
