You can cut dovetails on your band saw with only two jigs — the tail jig (shown on page 20) and the pin jig (shown on page 22). But I found it difficult to balance these jigs and a long workpiece on my band saw table.
To solve this problem, i built a 24" x 24" auxiliary table from a piece of 3A" plywood (Fig. 1). It clamps directly to the band saw table (refer to Fig. 4).
add runner. To hold the auxiliary table in position on the band saw. I glued a VV'-thick hardwood runner to the bottom of the plywood (Fig. 1). Cut the runner to width to match the miter gauge slot on your band saw. Then glue it in position so the edge of the auxiliary table clears the arm on the band saw.
new slots. After the runner was attached, I cut a slot in the auxiliary table directly over the runner (Fig. la). This slot (dado) is used to guide a runner that's on the bottom of the tail jig. Since I wanted to use my miter gauge for other jobs, I cut it the same size as the slot in my band saw table.
Next, to hold and guide the pin jig, I cut a second slot the same size and at right angles to the first slot (Fig. 1).
blade slot. With the slots cut, set the auxiliary table on the band saw and push it into the blade until an ll"-long slot is cut in the plywood (Fig. 1).
Then, to provide enough of an opening for a stop block, I widened the blade slot to VV'. (Since the runner was attached, I turned the plywood upside down and cut this on the table saw.)
stop block. The stop block stops jigs and workpieces that ride on the auxiliary table.
To make the stop, glue a 2Va1r x 3" block of IW stock to the top of a piece of plywood (Figs. 1 and 2). Glue the block at one end of the plywood, and then cut the ends of the block and plywood off flush. (I also chamfered the bottom edge as a sawdust relief.)
To keep the stop block square on the table, glue a W hardboard runner into a groove cut in the bottom of the stop block (Fig. it). The runner slides in the blade slot on the auxiliary table.
turn buttons. The auxiliary table is held down to the band saw table with a couple of turn buttons. To make the turn buttons, first cut spacer blocks just a hair thinner than the thickness of the band saw table (Fig. 3).
Next, drill a counterbored hole in the spacer block to accept a carriage bolt. Now insert the bolt into the hole, and then screw the spacer block to the bottom of the plywood table (Fig. 3). The carriage bolt head should be captured in the counterbore between the block and the plywood.
The turn buttons are rectangular pieces of Vi" plywood with a 5/ii;" hole drilled off center (Fig. 1). To tighten the turn buttons, you can use a wing nut or a plastic knob.
