cuts to establish the depth. Curve the bottom of the tenon so it flows into the bowl, as shown.

8 Turn the tenon to finished diameter, which should be the same as the largest diameter of the lid's tenon. For precise sizing, you can scrape or sand the tenon to final diameter.

(You 11 mount the lid and bottom for turning the other side by inserting the tenon into a jam chuck. The more uniformly they're sized, the easier it will be to turn both with one jam chuck.)

9 Mount a Jacobs-type drill chuck on the lathe tail stock. Chuck a W twist drill in it, and drill Vf deep at the center of the tenon. If you don't have a drill chuck for the lathe, mark the center after sanding, and drill the hole with a drill press when convenient,

10 Draw a guideline around the side of the tenon, V4" below the top edge, Form the sloped top of the tenon between the center and the guideline.

11 Sand the rim bowl and tenon smooth. Again, don't take too much off the tenon. Dismount the turning, and remove the faceplate from it.

12 On a drill press, drill four equally spaced W holes in the lowest part of the bowl, as indicated on the pattern.

Make a wooden jam chuck, and turn the outer surfaces

1 Bandsaw an 8" disc of 1 , /2-2"-thick scrapwood. Center the faceplate on one side, and mount it on the lathe.

2 Turn the face and edge true. Then form a recess in the front, referring to the Jam Chuck Section View drawing in the WOOD PA'ITERNS® insert.

The turnings's tenons must make a tight fit in the chuck, so turn the recess carefully. Start by roughing it to a diameter slightly smaller—say W smaller—than the tenon measurement. Then enlarge it in small increments, testing the fit after each cut. Scrape or sand the recess to final diameter. Taper the side slightly— about 1°—for a tight grip.

3 Insert the lid's tenon into the recess in the jam chuck, as shown in the photo top right. For more security, especially when making roughing cuts near the rim, bring up the tailstock, with a rotating cup center installed, to clamp the turning Into the jam chuck.

4 Mark the edge of the turning to indicate the thickness at the rim. On the face of the turnings, measure 3' 1 out from the center, and cut in Ya" deep with the parting tool Form the curve between the rim mark and the parting-tool cut.

5 Next, part off the wasteblocL Then turn the top of the lid to shape. Slope the surface surrounding the dome slightly so water won't stand on it.

6 Mount a drill chuck on the tailstock. Chuck a Mg" twist drill in it, and drill through the center of the lid, If you don't have a drill chuck, mark the center on the lid after sanding, and drill the hole later with a drill press,

7 Sand the turning with 100- and 120-grit sandpaper.
