1. Make your template... 3/4" MDF
The inside of your bowl... mark it, cut it, sand it.
Drill screw holes in each corner; in a ways not to interfere with main bowl.
... out of a blank 18.75" x 10"
2. Prepare the parts; yes, parts... all being 15.75" x 7" of varied thicknesses.
Plane, sand, and glue them together.
For the Oval bowl, they used:
Three planks of 1/4" Padauk
Three planks of Maple; 1-3/16", 3/8", 3/8" (bottom toward top)
Ultimate sequence, Top down, will be:
Padauk 1/4"
Maple 3/8"
Padauk 1/4"
Maple 3/8"
Padauk 1/4"
Maple 1-3/16"
3. Route out the inside of the bowl...
Place template on top, screw it on, fully route (hog out) out the pattern.
You could start out with a straight bit and hog out most of the insides...
Then switch to a bowl / tray bit (with bearing) and route around the edge using a collet extension to get to bottom.
4. With a compass or simple marking gauge w/ pencil, mark the width (maybe 3/8" to allow for sanding) around the bowl from the inside of the bowl.
5. Band saw cut out the outside of the bowl.
6. Roundover the top edges 1/8"... Bottom 1/2" roundover.
7. Sand, using belt sander, the outside...
They didn't mention how to Finish them... mineral oil, I guess... (?)
They even show you how to make an 11" square 3/8" clear acrylic baseplate to be used with your router!
They show you four bowls... Plain Oval, Casserole rectangular type, Circular, and a Divided one. All done with just ONE template.
