Introduction: How to Make a Bent Plywood Modern Mantel Clock
I’ve always liked unique clocks, so I decided to try and make one myself and here is what I came up with…I call it the Bent Plywood Modern Mantel Clock. To bend the wood, I used a technique called kerf cuts in which you cut almost all the way through the wood but leave just enough to still hold everything together. This was my first time doing this technique and I learned a lot along the way, and I hope you do too

Step 1: Cutting the Kerfs
For this clock I started by focusing on the kerf bent wood base.
I started by using my table saw and fence to cut a three inch wide strip of quarter inch plywood.
To leave enough room to mount the brass rod later, I left about an inch in the middle of board and made a left and right mark that I will use to know where to start the kerf cuts
For the kerf cuts I found that leaving the top two ply’s worked out just right.
Now there are plenty of websites that will give you the exact depth and width of the kerfs needed to achieve a particular bend, but for this project the only thing that’s really important is consistency
So to achieve this I made a mark on my sled and used that as a reference point to line up the back side of the previous kerf
I started from the right center mark I made, and then worked my way all the way to the end before flipping the board around and doing the same thing from the left center mark, leaving about an inch of material in the center
Step 2: Prepping for the Form
I’m not sure how critical the next step is, but I a shirt steamer to steam the wood and then dry clamped it around a bucket to get the wood “used to” the bend before the actual glue up
While that was drying, I moved on to making the actual form I would use to bend the wood around during glue up
For the total form, I needed a thickness of at least two inches, but since I only had ½ inch thick MDF, I ended up cutting for matching circles using my router and circle cutting jig
To glue the 4 circles together, I used the trick of wood glue for strength and superglue for a quick bond and then just set some weights on top of the four layers until the wood glue dried
To prevent the epoxy and wood from sticking to the form, I wrapped the edges of the form with packaging tape
To clamp the stand around the form I simply used a tie down strap which ended up working perfectly
Once I was confident the glue up would work, I moved on to adding the epoxy to each of the kerfs to help the stand hold its shape
Step 3: Adding the Epoxy
For this project, I used generic epoxy you’d find at a big box store
I wanted to actually showcase the kerfs as part of the design, so I went with a dark gray epoxy to contrast the lighter wood
It was a bit tedious working the epoxy into all the kerfs, and I did it in two rounds since I didn’t know how much working time I’d have with it, but in the end the epoxy worked great
Once I had epoxy in all the kerfs, I wrapped it around the form and clamped it tight using the tie down strap
Step 4: Cleaning Up the Epoxy & Cutting It to the Final Dimensions
Once the epoxy had cured, I removed it from the form
The epoxy did a great job of holding the shape, but it was a big mess, so I needed to sand all the surfaces to clean it up
To do this, I used a combination of my disk sander for the outside edges and my oscillating sander for the inner surfaces
I wanted the base to have the appearance it was coming out of the table or mantel, so I drew a straight line from side to side an inch or so up and then used my miter saw to cut the stand at just the right angle
This also added more surface area where the stand will sit on the mantel, which should have the added benefit of making it more stable
Step 5: Making the Hanging Piece of Wood
Next step is to create the piece of wood that will hang from the top of the stand and hold the clock mechanism
I used a nice piece of Sapele to give it a little color pop, but any wood would work
I used the bottom of a round container that was the approximate size I was going for to trace the circle onto the wood
Before cutting the circle out, I decided to drill the hole for the brass rod first since it’s easier to drill onto a flat surface
Now I could have used the circle jig again to cut out the circle, but since it didn’t need to be perfect, I used my jig saw to remove the bulk of the material and then snuck up on the circle line with my disc sander
Once I was happy with the shape, I moved on to drilling the hole for the clock arm to poke through
The wood was a little too thick for the clock arm I was using, so I routed out a little recess on the back of the wood to allow more of the clock arm to poke through on the front
Step 6: Mounting the Clock Mechanism
To attach the brass rod to the stand, I started by drilling a hole in the middle of the underside of the stand
Then I found a piece of scrap wood that would raise the Sapele piece up so that the hole in it would be parallel to the hole in the stand when laid on their back. This allowed me to glue the rod to both pieces at the same time
Then I used my Dremel and a cutting disc to trim the brass rod to length
Before attaching all the components, I applied Maker Brand Simple Finish to finish all of the wood pieces
Once everything was dry, I used some 5 minute epoxy to attach the brass rod to both pieces
Once the epoxy cured, all that was left was to attach the clock mechanism
I just followed the instructions that came with it and I was surprised at how easy it was to assemble
And with that, the clock was done!
