The belt. Many of us wear them every day. I measure things nearly every day. There was a time in my life that I carried a 6'ft. tape measure with me every day, but I found it cumbersome. One day, when playing with a laser cutter it occurred to me that the belt is prefect real estate for a short tape measure.

Similar to my Ruler Comb, this is an item carried every day that has un-utilized potential as a reference.

Step 1: Procure Supplies

You will need a belt.

This is the most important decision. I usually own belts for about 5 years before they become to stretched or ratty for daily use. I found trying to procure a nice leather belt online to be a very frustrating experience.

Etching your the belt you may wear everyday has several advantages- You already like it, and it is already stretched. I found that in the first month or so of wear my belts stretch as much as an eight of an inch (~3mm).

Color is an important consideration, as black etching on a black belt is hard to read.

For this iteration, I went with a Carhartt Brown Journeyman Belt because it seemed like it would be a stiff and sturdy ruler with a nice color for etching. It is not soft, so there is a comfort trade-off. I bought a size about 10" bigger than my waist so I would have a scrap to test on.

Non-leather belts have a high risk of containing PVC or other laser-unfriendly polymers that can damage your brain when etched. If you need to check if your belt has PVC, there is a really neat 'burnination' test done with a blowtorch and a piece of copper, outlined on Vimeo by Zach Hoeken.

HOW MUCH OF A CHANGE IS THERE TO STREACHING. IS THERE A WAY TO RECALIBRATE? THANK'S [ VLAD ]

Awesome! I would worry about leather stretch though. I know most of my belts are warped from normal wear. Saddleback Leather Co. uses embedded nylon straps in there leather bags to prevent stretching. Might look at some of there videos. This would also be a great Kickstarter campaign; I'd buy one!

One thing I thought of was wearing the belt for a few months prior to etching, as to minimize further stretching. With some of the belts I did I worried about stretching, but the Carhartt is super stiff and somewhat plastic-y in feel. I'd be surprised if it stretched more than a few percent. As far as Kickstarter goes, I put this 'ible in the public domain. Perhaps it will make it to market on its own!

I might take you up on the Kickstarter thing, I think tons of people would love these!

very cool man!

Very clever. I wouldn't worry to much about belt stretching since it looks like you used a latigo Carhartt. They often use it for belt leather because it's not prone to stretching as much as, say, veg tan. Great work.

Thanks! I didn't know there was such thing as belt leather, but I noticed the Carhartt wasn't soft enough to stretch when I bought it.

I'm guessing that your belt is pure leather so the inner-side is probably rough. Did you consider getting one with both sides smooth? This is generally accomplished by adhering a smooth sheet of leather to the rough side. Just thinking that two smooth sides doubles the amount of engrave-able area. Nice 'ible :)

Robb (author)  kakashibatosi2 months ago

Both sides were smooth. I think it is a bonded leather belt.

I did another one in black out of full-grain leather, and I used the rough side. It doesn't photograph well, as it is black-on-black, but it measures fine!
