To see table saws click here. Tapering the legs can be done with one of three methods. the simplest, though most tiring, is with a hand plane. Secondly, make a tapering jig as in photo 3 for the table saw. The jig is three pieces of plywood- a base, a side fence, and a rear fence. Position the side fence on the base at an angle equal to the angle of the taper, and place a rear fence behind the leg to keep it from being pushed backward. Don't get out your protractor to figure the angle of the taper. Remember "rise and run" from your algebra? Think of the angle as producing a line that "runs" a certain distance to the side over a "rise" of a certain distance. In other words, for every 12 inches of rise along the taper, it runs 1\4" to the side. Use this figure for all the legs, and begin each taper 12" above the bottom of each leg. To set the angle of the side fence on the taper jig, position it so that it is out of parallel 1\4" over 12" of length. First cut the taper into one side of a leg, then flip it 180o to taper the opposite side. Notice that now the freshly cut side faces the fence and does not contact it along the taper, only along the untapered area. Make a tapered wedge to fit between the fence and the freshly tapered edge. Run the jig against the rip fence on the saw. Note that the position of the fence determines the exact location of the taper along the leg. Note also that you must move the fence farther from the blade for longer legs because, being longer and at an angle, the end of the leg will be closer to the blade than that of shorter leg. |

The object is to remove 1\4" of width (and thickness) off all four edges of the bottom of the legs, and have the taper end 12" above the bottom. A third way to do this is on a jointer, as in photos 4 and 5. Set the jointer fence 1-1/8" from the front end of the knives (so minimal knife area is exposed), and clamp a stop block to the jointer infeed table 10 inches behind the throat. Set depth of cut at 1/16". Butt one end of a leg against the stop, and lower the front down onto the revolving cutters and outfeed table as in photo 5. Whenever using a jointer, always keep your fingers either behind the cutterhead or in front, never pass your hand over the cutterhead. Push the leg forward, move your left hand around the cutterhead to the outfeed table, push the leg through with the left hand and remove your right from the leg.
The effect of this cut is to take a 1/16" taper off that edge of the leg. Do this twice more for a total of 3/16", then do all other sides similarly. Once all legs are done, remove the stop block and run all sides again, with out lowering them onto the cutter, but starting well ahead of the cutter as usual. Take about 1/32" off on this pass. This cut removes the small divot that is formed at the top of the bevel when the leg is lowered onto the cutterhead. |

Whether you cut the tapers on the table saw or the jointer, when through a good way to clean off saw or knife marks is with a smoothing plane as in photo 6. Or, sand them with a belt sander, use a scraper, or, as a last resort, hand sand (yech!) Get out your rails, rip to width and cut to length. If you choose to veneer them with some beautiful wood, such as the bird's eye maple I used here, now is the time. But- why veneer at all, when you could just use figured lumber to make the rails to begin with? Because it will cost you an arm and a leg, that's why. Veneer, though not cheap, costs less by surface area (if not by board foot). |

Use contact cement to glue the veneer to your rail stock. Though not as strong as woodworker's glue, it is easy to use and more than adequately strong to hold veneer to wood. Cut out pieces of veneer that are larger than the rails to which they will be glued. Apply contact cement to both the rails and veneer pieces (photo 7) and then let it dry before you press the two together. Why? Because that's how the stuff works, don't ask me why. It bonds best from about 10 minutes after application to within a few hours thereafter. Read the label instructions carefully, and use only in an area that has cross ventilation, that is, two doors or windows open with a breeze going through, or out on the back porch.
It is possible that your wood will absorb too much of the first coat of
contact cement, so it is best to apply two coats if there is any question. When dry
carefully position and apply the veneer. Locate it correctly the first time because once
the cement grabs it is there permanently. They don't call it contact cement for
nothing. Bang it down with a rubber mallet (photo 8). |
