edging. Once the strike plates are screwed in place, the next step is to wrap a thin (Vis") strip of hardboard edging (K) around the curved part of the turntable. The edging is taller (wider) than the thickness of the turntable. This way, it forms a lip that keeps tools and materials from falling off the edge of the turntable.

One thing to notice about the edging is it's IV2" shorter than the distance around the turntable, see Figs. 8 and 8a. This provides clearance for a barrel bolt that's used later to lock the turntable in place, refer to drawing on opposite page and Fig. 10.

All it takes to attach the edging is to apply a little glue and hold it in place with a band

• clamp. After the glue dries and you remove the clamp, it's a good idea to secure the edging with screws, see Fig. 8a.

collar block. At this point, you're almost ready to install the turntable. But first, to prevent it from rubbing against the pipe, I added a collar block, see Fig. 9.

The collar block (L) is a thick piece of hardwood with a centered hole that's sized to fit the iron pipe. Note: For a tip on drilling this hole so the collar block fits snug around the pipe, refer to page 27.

pipe. After screwing the collar block in place, you can turn your attention to the pipe that serves as a pivot point for the turntable, see drawing on page 20. (I used a piece of 3/4M iron pipe.) The pipe fits into a flange screwed to the bottom of the base, see detail 'a' in drawing. Note: The pipe is

extra long so it can double as a pivot point for the carousel that's added later.

Before installing the pipe, you'll need to set the turntable in place. Then slip the pipe through the top of the base and turntable and thread the end into the flange. Here again, to keep the pipe from rubbing, I screwed a second collar block (L) to the top of the base, see drawing on opposite page.

barrel bolt. Finally, to lock the turntable in place, I added a barrel bolt, see Fig. 10. The bolt slides into a hardwood catch (M) attached to the side of the base. After gluing and screwing the catch in place, I located and drilled a hole in the catch to accept the end of the barrel bolt, see margin.

To locate the hole for the barrel bolt, slip a dowel center over the end of the bolt and press it against the wood catch.
