Introduction: Magic Wand - How to Splice Two Dowels

About: If its practical, I have no use for it!

A traditional magician’s wand has two ends that are a lighter color than the center piece. This Instructable shows you how to make a beautiful natural wood magic wand from two different wood dowels. The wand will be 14 inches long (overall), with two ends at 2 inches each and a center piece at 10 inches.

The joint shown is useful anytime you need to splice two dowels together.

Supplies

1/2 “ diameter dowels, two different species like oak, maple, cherry, walnut, poplar, or birch

Two short pieces of 2 by 4 lumber for the jigs

A very small piece of hardwood for the spline (tenon)

Wood glue

Table saw

Drill press

Clamps

Step 1: Make Two Simple Jigs

To begin with, let’s build a couple of very simple jigs to facilitate the project.

First, to cut a groove for the spline in the end of the dowels on a table saw you need to make a simple cutting jig. Cut a piece of a 2 by 4 lumber to 6” long. Trim the long sides flush. Using a drill press drill a 1/2” hole thru the wood 1-1/2 inches from the long edge. To complete the jig set the table saw fence to 1-1/2 inches minus half the width (kerf) of your blade. In my case that is 1-1/2” minus 1/16” equals 1-7/16”. You want to make a shallow (about 1/16” blade height) trial cut thru the center of the hole in the jig. Make the cut, and check it out; make adjustments as necessary to get the groove centered on the hole. Take your time to get it right. Once you have the perfect cut through the center of the hole note the fence setting and mark the side of the block that goes against the fence. Your cutting jig is ready.

Second, to glue the three dowel pieces for the wand together you need to make another jig.
Take a 13” long 2 by 4 piece of lumber and cut out a 45 degree v-groove on the table saw as shown in the pictures. Line the groove with wax paper, aluminum foil, or painters tape. This jig will keep the dowel joints straight during gluing. Your gluing jig is ready.

Step 2: Cutting the Dowels

This example uses maple and oak dowels to make a magic wand. Cut two 2” long pieces of the maple dowel, and a 10” long piece from the oak dowel. The cuts should be clean and square. Insert the longer dowel into the hole of your cutting jig so it is flush at the bottom. Set the blade height to 1/4”, and the fence to your setting from the prior step. Make a cut with the dowel sitting in the jig. Your dowel now has a 1/4” deep groove through the center, about 1/8” wide (most common blades have a kerf of around 1/8”). Repeat the cut on the other end of the dowel. Line up the two cuts to be parallel.

Now repeat the cuts for the two short dowel pieces, but only on one end each.

Step 3: Assemble and Glue

Prepare a small piece of wood 1/8” thick and 1/2” long by 1/2” wide. This is the spline (or tenon) to join the short dowels to the long piece. The spline should fit snugly into the cuts you made earlier, and be just proud of the dowel perimeter. Do a dry fit before applying any glue. You can use sand paper and a chisel or knife to shape the spline. For the spline use a hardwood with a nice color contrast to the dowels like the walnut in my pictures.

Apply wood glue to the spline pieces and the dowel grooves and faces, assemble, and clean off excess glue. Then lay the dowel into the v-groove of your gluing jig, and hold it down with spring clamps on all three pieces. Apply an F-clamp along the length of the dowel to close the two joints. Check that the dowel assembly is straight and well aligned. Let it dry.

Step 4: Finish Your Magic Wand

After the glue dries clean the joints with a light sanding; the alignment should be pretty good. Sand the wand with 100, 150, 220 grit sand paper. Leave unfinished or apply a finish of your choice.

The splines will show, of course; it is a feature to show off your woodworking skills!

    Tip 10 months ago on Step 4

    It's easier to center a hole on a slot than vice versa. Why do I say this? When making the jig, set the table saw for a very shallow cut and cut the slot. Then drill the hole from the slot-side, centered on the slot. Then back to the table saw, and cut the slot to the final depth, without changing the saw's setting. Another strategy is to cut the slot to finished depth first, then drill hole from slotted side (diameter to match width of slot) all the way through (with 120 degree twist drill). Slot will guide drill centered to it. Then flip over and drill with finished hole diameter (with twist drill). Using Forstner or other flat-bottomed wood bit with center point for the dowel-hole? Drill hole from slot side with twist drill as before, but only enough to form "spot" in bottom of slot. Then drill through with tiny twist drill, also from slotted side. It will center on the "spot". Flip over, and drill with Forstner bit. It will center on the tiny through-hole, and will be centered over the slot. There is no need for any measurements to achieve the alignment!

    Very good suggestion. It makes building the cutting jig easier and possibly more accurate. Thanks!
