Washer to Drill Hole on Round Objects
Mark SimpsonDrilling a hole on a curved metal surface can be challenging as the drill bit will want to walk on you and skate across the surface or move slightly or be misaligned from its intended location. Compounding the problem, sometimes the use of a centering punch can deform or damage thinner metal surfaces.
Here’s a quick tip to make your next drilling project easier. Using a flat washer or even a small piece of scrap metal as a drill guide, it will hold the drill bit in place and ensure the hole is precisely where you intended it. This also eliminates the damage caused when a drill bit bounces across the surface. Give this useful tip a try on your next project.
When fabricating stuff on your car, you know, sometimes you're going to have to drill a hole someplace, especially on round objects where you know it can get you know, hard to get a drill to not walk on you. And uh it can be especially hard if you're in like sometimes in sheet metal and on curved edges even on the body or, you know, even in fabricating stuff for brackets and stuff, quick way to get around that, you know, you can't always center or punch everything, uh, because then you risk deforming, especially thin wall metals, uh. So what I like to do is just grab like a flat washer or extra scrap piece of metal, uh, sometimes if it's close to the hole of the flat washer you can use that, otherwise you can drill a smaller hole in the flat washer to serve as your guide, then you can simply put that on top of where you want to drill. And that will hold it in one spot until you're done.
