Most of the information that I used to design this came from this PDF: http://www.personal.utulsa.edu/~kenneth-weston/chapter7.pdfI didn't get around to adding the intake/exhaust ports and spark plug.There is a video of this thing here: http:[email protected]/* <![CDATA[ */!function(t,e,r,n,c,a,p){try{t=document.currentScript||function(){for(t=document.getElementsByTagName('script'),e=t.length;e--;)if(t[e].getAttribute('data-cfhash'))return t[e]}();if(t&&(c=t.previousSibling)){p=t.parentNode;if(a=c.getAttribute('data-cfemail')){for(e='',r='0x'+a.substr(0,2)|0,n=2;a.length-n;n+=2)e+='%'+('0'+('0x'+a.substr(n,2)^r).toString(16)).slice(-2);p.replaceChild(document.createTextNode(decodeURIComponent(e)),c)}p.removeChild(t)}}catch(u){}}()/* ]]> *//6329093033/Print one of each part (either print all the parts individually or print the crank & eccentric together)Put the rotor and crank in the housing. Put the eccentric on the end of the crank.Spin the crank.
