PRODUCT CAPABILITIES The Porter-Cable 4200 series dovetail jig will help you cut these joints efficiently. An accessory kit will enable you to cut miniature versions of these joints for small gift boxes or cubbyhole drawers on a roll-top desk. The 4200 series also has the capability to cut more advanced joints (dovetails that skip pins, wood hinges, end-to-end joints, various types of angle joints, and joints with inlays). The specific model capabilities are: Jigs 4210 Dovetail Jig - half-blind,

ASSEMBLY The 4200 series dovetail jigs come fully assembled from the factory. However, the accessory templates (4211, 4213, 4215) require assembly. The supplied hex wrench can be used to attach the brackets and router bit depth guides to the template. A 3/8" wrench is required to adjust the height of the router bit depth guide. 3/8" ASSEMBLED JIG HEIGHT ADJUSTMENT ADDITIONAL TOOLS REQUIRED The router that you use with this jig must accept the Porter-Cable template guides supplied with the jig.

OPERATION Mount your workpiece in the jig properly. If the workpiece is not secure, it can be damaged when it moves. The jigs utilize two mounting positions for workpieces - horizontal and vertical. Some joints require both, while others require the use of a scrap board in the horizontal position (upper clamp) and the workpiece in the vertical position (lower clamp). Position your workpiece correctly left-to-right to produce symmetrical and tight-fitting joints. Tear-out from the router bit can

TEMPLATE SUPPORT For every type of joint, place wood in the top clamp, whether a workpiece or a scrap piece, to provide support for the router on the template. You can add extra support by inserting a second board (A) Fig. E1 (of the same thickness) in the top clamp to ensure that the template is parallel to the base across its length. This practice works very well for narrow workpieces. A E1 E2 Supported Unsupported POSITIONING THE WOOD You must position the workpiece correctly to produce attra

HALF-PINS VS. HALF-TAILS Traditionally, dovetails have half-pins cut on both ends (Fig. G1). Half-tails will be just as strong, but will not be as attractive (Fig. G2). If your joints are half-tails and you want half-pins, move the vertical board 1/2" either left or right, then move the horizontal board accordingly. The procedure is the same with the 4215 Miniature template, except that you move the boards 1/4". G1 G2 TEAROUT REDUCTION Tearout is unwanted splintering of the wood fibers that occu

TEMPLATE GUIDES Use the correct template guides provided with this unit to guide the router against the template fingers. To determine the proper guide for a given joint, place the template guide in the slot on the left side of the corresponding template. The guide should have a snug fit in the slot.

WOOD PREPARATION Properly preparing the materials for your project is the key to good-looking and tight-fitting joints. You must cut your wood at perfect right angles (Fig. L1). Cuts that are off even one degree will not align correctly (Fig. L2). Also, your workpieces must be flat and not cupped. L2 L1 Orient your wood so that end grain is joined to end grain (Fig. L3) to make the joint strong. Using the long grain (Fig. L4) in the workpiece will result in a weak joint.

PROJECT LAY OUT Keeping track of the outer and inner face of each workpiece and how the different parts mate with each other is very important. Step 1 - Lay out the workpieces face down and label the inside faces with an “I” (Fig. N1). Step 2 - Label the corners “A”, “B”, “C”, and “D” (Fig. N2). Step 3 - Label the tail boards (drawer sides) with a “T” (Fig. N3).

BASIC JOINTS THROUGH DOVETAILS The through dovetail has a look that is visually appealing, especially in boxes and chests. NOTE: For miniature through dovetails, use the 4215 accessory kit. Cut both the pins and tails in the vertical position. Cut the tails first. Use two routers (if possible) - one for the pins and the other for the tails - to make the process quicker and easier. If you are using the 4210 dovetail jig, you will need the 4213 accessory kit to make this joint. ITEMS NEEDED ITEMS

RABBETED HALF-BLIND DOVETAILS To produce rabbeted half-blind dovetails (drawer front), cut the pins for a half-blind joint after the drawer front has been rabbeted. The depth of the rabbet must be deeper than the half-blind router bit depth guide. NOTE: Cut the tails first. For miniature half-blinds, use the 4215 accessory kit. Use scrap wood until you are comfortable with the jig. Mount the correct offset guides - black for the standard and silver for the miniature. ITEMS NEEDED ITEMS NEEDED FO
