Cut all parts to size. As shown in our plans. ' this bench will cncirclc a small- to medium-sized tree. If your tree is larger than 12" in diameter, you may want to enlarge the benches somewhat. To make a bigger bench, you'll need to increase the radii of the ledgers, the length of the aprons, and the width of the seat planks To make sure that everything fits correctly before you cut the wood, make a new Tbp View, drawn to scale. There should be at least a 3" gap between the bench and the tree.

Cut the various parts to the sizes you have decided upon. Miter the ends of the aprons at 22Vi: All of the bench parts can be made from ordinary construction lumber, even the curved ledgers. Our outside ledgers were cut from 2 x 10s, and the inside ledgers from 2 x 8s. If you have enlarged the bench, you may want to use 2 x 12s and 2 x 10s, respectively. For very large benches, cut the ledgers from exterior grade W ply-wood. Sandwich two pieces together to make the 1W thickness required.



Cut the shape of the frame parts.

i— Enlarge the patterns tor the legs and aprons, and trace them on the stock. If the tree that these benches will encircle has large, spreading roots above the ground, you may want to use the Alternate Leg Pattern. Unlike the ordinary legs, these legs have only one outside "foot", and they are contoured to follow the shape of a large tree trunk. The disadvantage in using the alternate legs is that die individual benches are unstable. They can't be used unless they're assembled in a circle. If the need ever arises, you wouldn't be able to use the benches in other configurations.

TVace the arcs of the ledgers with a pencil and string. Clamp the ledger stock to your workbench, and tack a nail to the bench top as shown in Figure 1. The distance from the nail to the outside edge of the stock should be equal to the outside radius of the ledger. Tie one end of a string to the nail, and the other end to a pencil. Wrap the string around the pencil until the distance between the nail and the pencil is the same as the outside radius. Using this arrangement as a giant compass, trace the outside arc. (See Figure 2.) Wrap some more string around the pcncil, until the distance between the nail and the pencil is equal to die inside radius, and trace another arc. Mark the ends of the ledger so that its arc is a full 90.'

TKY Th Lay out just one inside and one outside ledger. After you cut them out, use them for templates to lay out the other ledgers.

Cut out the shapes of the legs, aprons, and ledgers with a band saw or sabre saw. Sand the parts to remove the saw marks. A disc sander (for the convex curves) and a drum sander ( for the concave curves) make short work of these sanding chores.

1/To lay out the ledgers, clamp the stock to your workbench and tack a nail m the bench top at the center ot the arcs. The distance from the nail to the outside of the stock (measured at the center of the stock) should be equal to the outside radius of the ledger.

Cut the seat planks. Cut the scat planks ' to length from I x 8 stock. Each plank must be along two opposite edges. To cut this taper, make a simple tapering jig that will cock the planks at IVi as you pass them through your table saw Cut one edge of all 24 planks. (Sec Figure 3.) Then cut the second edge, using a piece of waste from the first series of cuts as a spacer to hold the planks at the correct angle. (See Figure 4.)

3' Use a tapering fig to taper one edge of tho seat planks. Refer to the Tapering Jig Layout to see how to make this jig from a piece of scrap wood
