The idea of making a large wall clock has been floating around in my mind for a while. My CNC often gets used for small cuts so the idea of doing something that uses all the real estate was appealing.
I started by gluing up a panel of 1×8″ pine boards to make a blank big enough for the clock. It’s always tricky to get a nice flat panel, especially when using cheap boards from the home center, but it came out reasonably flat and I kept it clamped down to the surface of my CNC machine when I wasn’t out there working on it.
The next task was cutting the face of the clock out of 1/4″ MDF. Instead of starting from scratch, I purchased a vector art design from Etsy, but with all the modifications I had to make to it, I might have been better starting from scratch (or at least from a different store.) I eventually got it all programmed and even though it would take a lot longer, I decided to run the whole pattern with a 1/8″ bit instead of a 1/4″ bit. That would give me more definition in any sharp corners. The whole cut ended up taking around 3 hours with some stopping in the middle to make adjustments.
After a lot of sanding, I finished the back with some stain and used an off-white spray paint for the face. I usually got for pure white but decided to try off-white this time. I wasn’t sold on the idea until I got to the very end of the project.
For the clock parts, I used clockparts.com. I had used them once before and was happy with their stuff. This time I purchased their high torque clock movement to support moving those giant hands. When the parts arrived, I sprayed the white hands to be the same off-white color as the face.
I cut the blank into a giant circle on the CNC and I was careful to hole right at the center which came in handy for finding the same center again later and for mounting the movement. With the blank flipped over, I pocketed in a whole for the movement and I also added some keyhole slots for mounting it on the wall.
We hung it above the fireplace in the front room and while it’s a fun piece of art, it’s a little tricky to read the time from it. The counterweight on the minute hand and the rings that encapsulate the Roman numerals are all distracting. I don’t know that I’d change the design at all though.
I see these on Etsy and Instagram and feel “meh” about them in general, but I’m super happy with how this project came out. It wasn’t a huge project but it had enough small new things in it to really entertain me.

But First, Pray
Elijah’s school has a charity auction every year. Last year I made coasters with the school logo on them. This year I thought I’d make a sign since those are so popular. I ended up with a sign that says “but first, pray”.
I didn’t want to just make a painted sign. I wanted the words to stand proud of the surface. A laser cutter would be the right tool for the job, but I don’t have one and our maker space is closed while the pandemic rages. I bought a handful of cheap 1/16″ CNC bits assuming that I would break a few of them in the process.
My first attempt was cutting everything out of MDF. That worked ok for the large “pray” word but the smaller individual letters didn’t hold up. The MDF wasn’t strong enough to hold together at that scale. I then made them out of 1/4″ poplar and they worked fine. I sanded and painted everything, but then I realized that I didn’t have a great way to keep those tiny letters stuck on the wood. I was nervous that one little bump might knock some of them off. After trying a few things, I decided to use my Cricut to make a stencil for the individual letters and then I glued on the bigger word.
I finished it off with a keyhole slot on the back so that it could be mounted easily on a wall. The keyhole bit I have is a 1/4″ shank so normally I put a different collet on the router in my router table, carefully measure and align everything and then pray that it all works. This time I realized that I could just stick the keyhole bit into my CNC and manually drive the machine to get the cut exactly right. It was so much easier!
The end result looks pretty simple but it took a ridiculous amount of time, especially when spread into the tiny amounts of free time that I’ve been able to devote to it. Hopefully it raises a few bucks for the school.
