I used a piece of scrap redwood: The Easel design expects something at least 10" long by just under 4" wide, and the deepest cut is 1/4" (completely adjustable by you of course). At minimum, I’d go 11" long, just to provide space to help hold it down on either end.
Note, redwood is very soft: I’d recommend a harder wood to help hold the fine details easier.
For the below cut, I used a 90 deg V-bit & and 1/4" 2-flute upcut endmill. I had my DeWalt 611 set to speed “2” the entire time.
I also used more aggressive cut settings than Easel’s defaults since redwood is so soft: If you have any concern, for each of the Easel “Workpieces” you’ll open in the below steps, you can change the “Cut Settings” from “Custom” back to “Recommended”, and go from there.
For this step, you need to swap bits: This is the technique I use in Easel:
You can now select the ‘Endmill’ Workpiece from the bottom of Easel, and start that cut, using your new home position. It should only take a few minutes to cut the pockets.
You can now remove the piece from the wasteboard: I trimmed off the ends with my table-saw, and liberally sanded all sides with some 200 grit. From there, I applied some “Natural” Minwax stain to make the redwood grain pop, and let it sit out for a few days to get rid of the smell.
CAUTION: When using this candle-holder, only use self-contained votives that come in the little metal tins: Do not use candles similar to my example photo (I was simply out of votives at the time) that have no metal protection : You do not want a candle to burn all the way down, and ignite your nice, stained, wood, candle-holder, and everything else around it! Use caution around fire at all times!
