  • Being the proud owner of a tandem combination, you’ve probably experienced the power of what it an do. With up to double the number of teeth (44) and twice as wide (1″) a cut as on a standard Lancelot or Squire any combo is going to significantly increase your productivity simply by removing more wood with less effort. These tips will help you best utilize this great addition to your tool inventory.

    I personally find using a tandem easier to use than a single blade. It gives me more depth control and the wood removal rate is nearly twice as much. My favorite is a double 14 tooth Lancelot combination for major hog out removal and overall shaping, working down to a single Lancelot or Squire for finish, shaping and detail. Like many of you, I want to remove waste stock as quickly as possible. These tools get the job done in a hurry.

    Again, I‘m going to assume some givens and provide some technical information.

    1. You’ve read all the instructions, have properly mounted both blades, secured your work piece and are wearing protective clothing. (I strongly recommend the use of a full face visor, especially when making raking cuts).
    2. You’re familiar with the benefits and finishes of the seven different combinations. If not, please refer to the Tandem Combos page on this site which details each one.
    3. The tips are for right handed users. We wish they made angle grinders suitable for left hand use but as none are available, we go with what we’ve got. My apologies to all you lefties out there.
    4. The width of cut when using any two Lancelots mounted side by side is 1″
    5. The depth of cut can vary depending on the hardness of the wood. It has a maximum depth of 1-3/16″.
    6. The bottom surface of the cut will be smooth because both blades are 4″ in diameter.
    7. When using a Lancelot/Squire combo, the offset blades will leave a bench style finish when performing a straight or plunge cut.
    8. This combination is very useful for rapidly and smoothly removing wood surfaces in the raking position for either convex or concave shapes. It’s also great for removing bark or large slices across a surface.
    9. If I make reference to cuts mentioned above, the action of performing them is basically the same with one major difference. You will remove up to twice as much with each pass. In essence, for rough out work use the tandem combination to suit your needs, then switch over to the appropriate single blade for your final effects.

    Plunge cuts for rough carving with a double Lancelot combination. Same action as for use with a single blade. Each cut will be 1″ wide but marginally shallower than with a single blade. Because of the randomness of this method the bottom and sides of the total area will probably be uneven. After making your consecutive cuts next to each other, smooth out the rough areas using either/or a combination of the side to side and raker cut.<

    Plunge cuts for rough carving with a Lancelot-Squire combination. Same action as for use with a single blade. Each completed cut will leave a bench finish 1″ wide. To hog out the higher section with each consecutive pass, it is best to start at the right and work left. With each pass place Lancelot on the high section to remove it. This motion will simultaneously make an adjoining cut with Squire. Once completed, smooth out the bottom using the larger Lancelot blade on this combo with the side to side cut. You can also use the raker cut.

    Long and short cuts with a double Lancelot combination. The procedures are the same for this tandem as they are for single blades so just refer to that section for greater detail. The biggest difference is that the cut will be 1″ wide for as long as you want it. To make the trench wider, simply cut next to it. You can also round out the sides by tilting the blades to about and 80° – 85° and pull gently toward you. The mere fact that it removes so much, so quickly is phenomenal. The most aggressive and my favorite combination is to pair two 14 tooth Lancelot’s.

    Slicing with a double Lancelot combination. You can very easily slice off side sections of wood with long downward strokes. This is a very efficient method to remove side stock on medium to large work pieces. We’ll take the example of a stump which requires side shaving just because it’s to big around in certain sections. The bark has already been removed and you want to shape the base to seat a bear, troll or eagle – your choice!. Working on the perimeter of the wood, you’re going to systematically slice the sides as far down as you want to go. Start by holding the disc grinder in the vertical position with the blades about 1″ above the wood on the outside of the stump. Commence to penetrate the side in a downward stroke as far as you want to go. There is little downward resistance simply because you’re carving on the outside and the only opposition is the wood at the bottom and one side of the teeth. Repeat this cut as required, moving around the stump. You can also stop and start to reposition the workpiece to slice different side sections. You may be happy with the end result, however final shaping can be accomplished using different cuts described.

    Slicing with a Lancelot – Squire combination. It is the same action as described above, however you’re going to leave a bench step cut with every pass which has to be repeated more frequently. I strongly recommend that you use the raker cut for this type of work because of the advantage in using the offset blades.

    Sideways cutting using the double Lancelot combination. The method is the same as when using a single blade. The difference is better control and far more wood removal with less side to side strokes. You’ll remove surface wood and go deeper faster, at up to twice the speed of a single blade.

    Raker cuts using the double Lancelot combination. Again, this application is the same as when using a single blade. You’re cutting with the face of a the outside Lancelot blade only, so the finish and speed of cut will be the same as a single blade.

    Raker cuts using the Lancelot – Squire combination. It is the addition of Squire’s 12 or 18 teeth forming the offset blade configuration with the larger diameter Lancelot which makes the big difference. Whether removing bark, carving convex and concave surfaces like the inside or outside of bowls, rocking horses or any curved surfaces, this is where this combo comes into its own. Again, a word of caution – the raker cut makes chips and sawdust come straight toward your cheeks. They can sting! So make sure you wear full face visor protection. Offsetting blades makes Lancelot-Squire ideal for removing wood using the face teeth of both blades. The procedure and hand positions are the same as when using a single blade, however, the wood removal rate is incredibly faster.

    Feathering using the double Lancelot combination. The exact same technique applies to this combo as the single blade, however, you will have more control and remove sections faster using this combination than a single blade. Using a gentle touch, you can move across the surface of the wood in any direction using repetitive side to side or up and down motions. Whether you want to shape the sides or top, hold the grinder in the vertical or horizontal position to gently feather small sections at a time. You will find this technique extremely useful toward to the end of your power carving for final shaping and detailing, for example, on a rocking horse. Again, remember to use a very light feather touch. You don’t want to gouge the work at this point. When completed, these areas are ready for final sanding.

    Changing position of auxiliary handle for confined carving. When working in confined spaces like the inside of a bowl, the handle in the normal raker or downward cut positions will be on your left. This can sometimes be a hindrance when you’re maneuvering the grinder around the curved side surfaces, more especially if it’s a deep bowl. This tip is invaluable for working with just the blades and safety guard in confined spaces without the handle getting in the way but with you still retaining full control. If you own a disc grinder with three positions for the handle, one each at the top, bottom and middle, change the handle to the middle position. It takes about a minute. In this position the handle protrudes out the back of the grinder directly over the blades. Now feel the difference! You can cut and shape inside confined areas with absolutely no intrusion from the handle which you’re now holding in a different position. By applying slight downward pressure the blades will effortlessly shape the sides of your workpiece with no restriction from the handle.
