For this reason, it is recommended that you spend some time practicing using the Domino joiner before you begin using it for your fine woodworking projects. For best results, observe the following tips: > Always secure the workpiece firmly. > Hold the Domino Joiner firmly by the handles and keep it flat against the workpiece. > Plunge the mortising bit into the workpiece with a slow and steady pace. Choosing the Right Domino Tenon Size Because the Domino system is a form of the classic mortise and tenon joinery, it should follow much of the same guidelines of mortise and tenon joinery. Here are some guidelines to assist you in making your choices: > When the strength of your workpieces is comparable to the strength of the Domino tenon (e.g. general hard woods) then the thickness of the Domino tenon should be approximately 1/3 the thickness of the workpieces. > It is acceptable to use a tenon that is slightly thicker than 1/3 when the width of the Domino tenon is relatively narrow compared to the width of the joint. This is why 8mm Domino tenons are the most common for joining .-inch lumber. > For softer woods, such as pine, the joint will be stronger when the tenon is 1/3 or slightly less. > For plywoods, especially low-grade construction plywoods, the Domino tenon is much stronger than the surrounding wood, so it is best to maximize the strength of the substrate by minimizing the thickness of the tenon. Domino Tenon Placement Guidelines There are no steadfast rules on where tenons should be placed, especially when they are used for alignment purposes. For edge joining boards, a typical placement might be 6 to 8 inches apart. However, when tenons are used to strengthen a joint, you might be tempted to place the tenons too close together. This can actually weaken the joint by removing too much of the substrate material. > A wide mortise weakens the substrate, so it is better to have several narrow mortises with uncut space in between, than it is to have a single wide mortise with several tenons side-by- side. > When placing several tenons close together, leave at least twice the tenon thickness between mortise holes. As a general rule, this means the minimum tenon spacing should be about 10 mm to 20 mm, but they can be spaced much wider. > When creating stacked mortises for extra thick lumber, an extension of the “1/3 rule” mentioned above still applies. Specifically, the distance between mortises, and the distance between a mortise and the wood surface should all be equal to (or larger than) the thickness of the tenon. Plug-It® Power Cord The Domino joiner comes equipped with a removable Plug-It power cord. To install the power cord, insert the cord into the inlet on the tool with the key and keyway aligned, and twist the locking ring. Reverse the procedure to remove the cord. Note: Turn the outer locking ring .-turn to fully engage or disengage the cord. If the lock is not fully engaged, the cord may fall out of the socket. Turning On the Joiner WARNING! To reduce the risk of injury from contact with moving parts, never turn on the tool when the fence body is removed or does not automatically return to its forward rest position. The power switch for the Domino joiner locks into the On position when activated. When working with the tool for the first time, it is recommended that you become familiar with the operation of the switch before you plug the tool into a power outlet. To turn the joiner on, push forward and down on the power switch. To turn the joiner off, press down on the back of the power switch to release the latch. Using Dust Extraction The Domino joiner is intended to be used with a dust extraction system. Using the machine without dust extraction will cause it to clog with wood chips. When installing a Festool dust extraction hose onto the dust port of the machine, it is easiest to insert the hose at an angle and then push it on the rest of the way as shown to the right. Note: If you have a non-Festool vacuum system and your vacuum hose does not fit the dust extraction port, a Festool vacuum hose will fit many other brands of vacuums. Using the Locating Pins or Edge Stop Dogs On the front of the fence are a pair of either locating pins or edge stop dogs, depending on the manufacturing date of the joiner. These are used to register the tool against the edge of the workpiece or against a previously machined mortise slot, and provide rapid and precise placement of the tool on the workpiece. > The distance between the locating pin/dog and the center of the mortise slot is 37mm (1-7/16 inch). > When the locating pin is against the edge of the workpiece, the edge of the workpiece will be visible in the center of the guide window on the top of the fence (refer to right hand image below) > The edge stop dogs can be locked in the retracted position when not needed. Refer to page 12 for more information. (The locating pins cannot be locked in the retracted position.) Disabling/Retracting the Edge Stop ...
