how to remove multiple start points in sheetcam

The holes they make will be out of round and off center. I have a couple criticism of the article:įirst, hand sharpened drill bits do not drill straight. it will jam up and possibly break the bit and ruin whatever you’re working with, depending on how strong all of your equipment is. What this means is as long as your bit is reasonably close to center, you will always drill a perfectly centered hole. I don’t mean close to center, I mean perfectly centered on the rotation. It doesn’t matter how far away from center he starts, all the guy with the blade has to do is move sort of toward the middle and it automatically works in to dead center. Seriously, watch normal lathe work with someone working on the end rather than the side. This is the whole point of lathes, and why you can do perfectly symmetrical work on a lathe. With the work rotating and the bit stationary this relationship is flipped, and this causes the cut of the drill bit to always seek the center of the work, rather than the hole it’s cutting. This does nothing to center the hole, but it does drill a very nice, perfectly straight hole, which is the point of drill bits. With the bit rotating, the tip of the drill bit is always central to the rotation, and central to the hole it’s drilling (not the piece the hole is being drilled in, obviously, but the hole itself). At first glance I thought they were the same, but it’s actually not the same at all.
