	The sycamore bowl with ebony rim.
	Always wear protective clothing and a face shield for woodturning projects.

In this episode of DIY's Wood Works, host David Marks creates a hand-turned bowl from sycamore. In this second segment, he adds an ebony rim to the front face of the bowl

Materials and tools used in this episode:

Sycamore stock
Ebony stock for rim
Alder or scrap-wood for sacrificial blocks
Lathe
Turning faceplate
Turning hand-tools -- gouges, scrapers, parting tool, etc.
Jointer
Drum sander
Band saw
Pneumatic angle grinder
Disc sander
Jig saw
Cordless drill
Circle tracer
Circle template
Calipers; double-sided calipers
Epoxy glue
Cyanoacrylate glue
Clamps
Straight-edge
Compass
Carpenter's pencil
Chalk
Sandpaper, various grits
Safety glasses or goggles
Protective clothing for wood-turning
Face shield for wood-turning

Safety Alert: Wear protective clothing to protect yourself from flying chips and shavings when woodturning. Also wear a face shield to protect your face and eyes.

Safety Alert: Always wear safety goggles or safety glasses, and follow proper safety precautions, when working with wood, power-tools, saws, drills, routers, etc.

Laminated Ebony Rim

• Use the circular plexiglass template (used earlier to mark the rim on the sycamore bowl) and white chalk to mark out the segments for the rim on to the ebony strips cut earlier.

  Tip: The template was made from clear plexiglass. In this way, the grain pattern can be seen and matched from segment to segment, around the circle, in the figured ebony.

• Once the segments are outlined on the ebony, carefully rough-cut them out using the band saw (figure A).

• At the disc sander, carefully refine the joint line of each segment (figure B).

• Join each segment to the face of the partially turned bowl using cyanocrylate glue (figure C).

• Use standard spring-clamps to get even pressure around the rim. You may want to spray on some accelerator to speed up the drying time (figure D).

• Once all of the ebony is attached, and the glue has hardened, remount the bowl to the lathe (figure E).

• Then use the parting tool to define the inside and outside profile of the ebony rim (figure F).

• Check for low points, mark them with chalk and turn and shape the rim further until you've obtained a uniform circle.

• The round-point tool (figure G) is a great tool for creating beads and detail work. It's a scraping tool, not a cutting tool, and is safe to use because it won't dig into the wood.

  Tip: It's especially important to keep this tool, and all turning tools, very sharp. Use a fine diamond-stone to hone the three edges of the round-point tool.

• Use the round-point tool to define the transition between the sycamore and ebony, slightly rounding the top edges of the ebony. Essentially, the glue line should be invisible to the eye, and the edge should be slightly rounded.

• With the outside profile complete, smooth out any rough spots using a right-angle pneumatic angle grinder and 80-grit sandpaper (figure H). When sanding, let the lathe turn slowly at around 300 rpm. Continue sanding, working your way up to 220 grit.
