IMPORTANT SAFETY PRACTICES Always read the instructions that come with your routers and cutters to ensure you are following safe working practices. Before making adjustments to the router or changing a cutter, always remove the plug from the socket first. Ideally mark the plug with the word ‘router’ to ensure you pull the right plug. Ensure when fitting the cutter you insert the shank until at least the ‘K’ mark on the shank. This will prevent vibration and/or damage to cutter or router. FIRST STEPS TO GETTING STARTED 1 2 First run a bearing guided edge mould around the outside of a square piece of material or against a long edge. Keep the router flat on the work and the bearing tight to the edge and feed at a steady rate. 4 3 Practice using the fence by making a rebate and a continuous groove. Close the fence cheeks. Keep firm pressure at the leading edge of the fence as the cut starts. Towards the end transfer pressure to rear of the fence. 5 Using the V groove cutter, practice freehand engraving & sign writing. Set a minimal depth of cut with the plunge stop. First sketch in pencil the lettering required taking into account the thickness of cut you will make. 7 Using the fence, practice plunge stopped grooves. First set cut depth with depth stop. Plunge router into the work keeping firm pressure against the fence, move smoothly until you reach the stop point and release the plunge. 6 The V groove & fence are used to good effect to make false panels. Use the fence to rout the outer edges to give the effect of a frame & then adjust it to make the infill panel lines by using the plunge to start & stop the cuts. 8 Cut a circle by fixing the trammel guide to one fence rod. Mark the centre and radius of the circle. Using the straight cutter, position trammel on the centre point and adjust the fence rod until the inside edge of the cutter is against your mark. Keep firm pressure on trammel point to prevent it lifting. Always wear safety eyewear to ensure you protect your eyes from flying debris and a face mask to stop the inhalation of fine dust particles. Ear defenders are also advisable. Making grooves beyond the reach of the fence is easy to achieve by clamping a batten as a guide and running the router against it. Mark up the position of groove required and position the batten appropriately. 9 Using a bearing guided moulding cutter, rout a mould around the edge of the circular blank. Move in an anti-clockwise rotation keeping pressure directly over the workpiece as you work to prevent tipping. Templates can be easily made from 6mm MDF for replicating shapes. Ensure any edge the guide bush has to follow is smooth as any roughness will be replicated in the finished workpiece. Secure the template to the work and keep the guide bush tight to the template. TIPS & ADVICE TO GET IT RIGHT For internal moulding or template work, feed the router in a clockwise direction. For outside work feed in an anti-clockwise direction. Keep the weight over the workpiece to prevent router tipping. For deep grooves or edge work, take repeated passes to prevent motor overload. Plan the order of cuts to prevent breakout. Rout the cross grain edge before the long grain edge. Ensure an even feed speed to prevent burning. Burn marks often happen when the user repositions themselves, so the router path should be planned in advance. With experience the cutter can be pulled away from the workpiece at the crucial points to prevent burning. To remove burning a second pass can be made.
