- (1) piece of 3/4" plywood (preferably something furniture grade with no voids) 24"x48"
- (1) 36" length of 3/8" diameter dowel (the one shown is oak)
- Wood glue
- (2) 36" long pipe clamps
- Sander, belt or orbital
- Chopsaw (must have angle adjustable base)
- Small laminate trimmer router (optional)
Step 1: Plywood discs and sled
I used to make the discs with the circle cutting jig for my plunge router shown in the attached pic Fortunately I live in the Bay Area and I now make these at TechShop with the help of the CNC ShopBot. I can now knock out the 3 dozen discs in about 30 minutes of machine time. I also recently assembled a sled for holding the log which greatly help in the upcoming slicing step.
Once all the discs are cut start slipping them on to a 36" length of 3/8" dowel. Don't be shy with the wood glue in between layers. Squeeze them all together with 2 pipe clamps. The extra length of dowel gives you something to hold onto when your cutting towards the end of the log.
When the glue is dry it's time to sand. A nice belt sander makes pretty quick work of this but it can by done with a handheld small random orbital sander. Doing it by hand always reminds me how much sanding has become my least favorite part of any project.
