I think a Rotary engine would be more interesting.

Sun Gear (author)Yerboogieman2009-12-01

rbiernacki (author)2009-10-02

Sun Gear (author)rbiernacki2009-11-09

one that somebody made and had enough parts to add a blower thought "aww what the hell"

knexfreak95 (author)2009-06-21

could have had better cams

Sun Gear (author)knexfreak952009-11-09

they worked and went off on time that was good enough for me

what is the combination of gears you use to get the cam speed a 1/4 of crank speed. this is for timing by the way and im stuck. I can only get 1/3 of crank speed or 1/5 of crank speed. help would be much appreciated.

Sun Gear (author)661rhys2009-02-16

i had to make my own

661rhys (author)Sun Gear2009-02-16

And how did you do that?

Sun Gear (author)661rhys2009-02-17

K'nex projects aren't really for me and I usually don't even read them, but this project... wow!

What a great replica, this has got to be the best k'nex project on here IMO

Sun Gear (author)mikeasaurus2009-01-28

mikeasaurus (author)Sun Gear2009-01-28
