I puzzled a little over how I could tell but didn't come up with much. <br /><br />I could measure current draw by the motor under identical cuts, which would equate to input power. Say make two parallel dry cuts in aluminum - one with Dykem one without. Maybe? <br /><br />Either that or look at the cutter under a good magnifier and see how clean it looks either way. <br /><br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-80104475416372468842018-07-25T00:14:17.069-04:002018-07-25T00:14:17.069-04:00Wonder if machinists bluing (dykem) does the same ...Wonder if machinists bluing (dykem) does the same thing?ravennoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-15283579455988747292018-07-24T23:34:54.691-04:002018-07-24T23:34:54.691-04:00That's interesting.

My armoring teachers taught me to always use Sharpies and to cut just on the colored edge of the mark, especially when cutting aluminium.<br /><br />Seems they knew something from practice that the professors didn't know.<br /><br />Now that I think about it, it is much like using masking tape on the cut line when cutting plywood or thin wood to keep the top grain from splintering and giving the cutter a cleaner edge.<br />Beanshttps://www.blogger.com/profile/15293778848879361153noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-23965909173535424592018-07-24T22:23:43.846-04:002018-07-24T22:23:43.846-04:00Very interesting.Very interesting.LLhttps://www.blogger.com/profile/05538854359365988863noreply@blogger.com
