An adequately sharpened pencil
Wood stain (I chose Minwax golden oak)
Clamps (A minimum of four, eight to work with both rings simultaneously)
Sanding device (I used a Metabo Compact sander with a rough sanding stone and 800 grit sandpaper)
Four 9 1/4" x 9 1/4" squares of 3/4" thick plywood (I got one 24"x24" sheet from Home Depot for ~$6)
Cargo straps (Search HarborFreight.com for cheap ones ~$1.49)
Since I already had all the tools I needed except for the wood stain, this instructable cost me <$10, and these rings normally sell for ~$90.
Note: All measurements were obtained from this tutorial (http://shootingboard.net/fitness/rings/). I am not responsible for any bodily harm including dismemberment, brain damage, stomach aches, mild disappointment, or third degree burns that result from performing the outlined steps or while using the resulting rings. Play safe.
P.S. I've also finished making parallette bars out of PVC and a wooden "mushroom" pommel horse trainer, which I'll be adding instrucables for next.
Step 1: Cut and Glue Plywood Squares
2. Glue two pieces of plywood together using generous amounts of epoxy or wood glue.
3. Apply four clamps to four corners of glued plywood while it dries.
4. Repeat step 2 with two remaining pieces of plywood.
5. Wait at least four hours before proceeding.
Step 2: Rough Shape Rings
2. Use a jigsaw to cut out the rings. For the inner circle I first drilled a few holes so I had a place to start the jigsaw.
3. Since I do not own a router I used a Metabo sander by hand to do all of the shaping. First, clamp your rings to a bench and work with a rough stone on a 45-degree angle to create a beveled edge on the outside and inside of each ring. That will be the basis for later light sanding.
4. Continue sanding with the stone until the bevels are as close to a circle as you can get. I found the best way to work them was to clamp them horizontally, hanging off the edge of the bench.
Step 3: Finesse Those Rings
This part is where it becomes a labor of love. I spent about 2 hours sanding both rings until I was happy.
Step 4: Damage Control (if Necessary)
Step 5: Stain!
Step 6: Play and Share
