I am on my second try and it is good but not perfect. I had to soften the ends of a 20mm shaft so I could drill one end and make a keyway on the other end. I heated the ends slowly until they just turned orange and let sit to cool. I did one end at a time. </div><div>Any tricks to this?</div><div>Hank</div></div></body></html>
