I was talking about engraving IKEA cork coasters, and how to detemine the thickness of the bottom. There are lots of ways to do this, but for my money, using your digital calipers is the fastest and most accurate way to get there. This technique would work with anything with a “lip”, so you can adapt it to your specific needs. Here’s how:
Get a small item that is thick and will fit inside the coaster. A nice big 6-sided die will work fine.
Many Calipers have a little bar on the back at the end of the scale that acts as a depth gauge. You’re version certainly looks sturdy enough to have that feature. I use a stainless steel scale and calipers to measure depth specific to various points so I can see if there is a high or low point or grade of some kind.
Funny how as soon as I read this, my brain is like, “duh”. Probably something I could have figured out if there was a need, but I appreciate you sharing so I don’t have to rack my brain only to have an ah-ha moment under stress. Thanks, again!
