SHOP PROJECT (For more on this, refer to page 13.) ) TRIM CORNERS. Now you can start to shape the lower support. To create the ends of two of the arms, I tilted the head of the miter gauge and used the table saw to trim off the corners of the blank, see Fig. 7. (Since the blank is already squared up, you won't have to trim the third end.) CURVED SIDES. The next step is to lay out the curved sides of the support. An easy way to do this is to bend a thin, flexible strip along the desired curve, see Fig. 8. (I wanted a 1" bow.) But you'll need something to keep the ends of the strip from springing back. A couple of scraps with pointed tips work well. Just clamp the scraps to the blank so the tip aligns with the layout mark, see Fig. 8a. Then trace along the bottom edge of the strip. CUT TO SHAPE. All that's left is to cut. the lower support to shape. I roughed it out on a bandsaw then sanded the edges smooth. UPPER SUPPORT Except for a couple of details, the upper support is just a smaller version of the lower support. DRY ASSEMBLY. To ensure a good lit, it's best to dry assemble the stool and turn it upside down on a blank that's been glued up for the upper support, see Fig. 9. Then simply lay out the ends of the arms. Since I started with the ends, I had to work "backwards" to lay out the shape of the lower support, see Fig. 10. Here again, you'll need to drill a hole to accept the post. (It's a 2"-dia. hole to fit the thick part of the post.) But this time, the hole isn't threaded. HSSE1BLY All that's left is to assemble the two supports and the legs. You won't need glue for this. HANGER BOLTS. That's because they're bolted together. The legs fit over hanger bolts installed in the ends of the arms, see drawing and margin on page 8. Tightening nuts on the ends of the bolts secures the legs. And I used snap-in metal caps to cover the bolts. 9 FIRST: use band clamp to dry assemble stool I SECOND: - use 1v2"-thick scrap block to support leg at end of blank glue up 1'/2"-thick blank for upper support- No. 46 ShopNotes 9 aux. fence lower support blank align tip VIEW FIRST: lay out sides of triangle SECOND: draw lines between the centerpoints on sides of triangle and ends of arms FOURTH: drill 2"-dla. hole THl RP: lay out curved sides |
