This way the block will be perfectly aligned to the mast bend direction.\u003c\/li\u003e\n\u003cli\u003eWith one block set as reference, lay the mast and block on a flat surface and align the second block to same flat surface. With one block tightened, the other may be moved without losing alignment reference.\u003c\/li\u003e\n\u003cli\u003eUse the side notches to measure the positions for forestay and shrouds. Alternatively build a reference ruler with markings for bands and holes. Use the side notches to align the drilling holes to the markings on the ruler.\u003c\/li\u003e\n\u003cli\u003eDrill carefully with a 1.5mm drill. Be careful to keep the drill aligned not to widen the reference holes. If the tool is used carefully it may be used to drill multiple masts before needing replacement.\u003c\/li\u003e\n\u003cli\u003eIf a larger hole is needed, drill a 1.5mm hole, remove the drill block and re-drill with a wider drill bit. Alternatively carefully drill the block with a wider bit to widen the reference hole.\u003c\/li\u003e\n\u003cli\u003eTo align a gooseneck:\n\u003cul\u003e\n\u003cli\u003eCheck which ends of the gooseneck fit into the reference guides. Some models require removing the boom end fitting. Some models will align using the screw that holds the boom end fitting.\u003c\/li\u003e\n\u003cli\u003eThe pin or screw on the gooseneck should fit snugly into the alignment groove. Add tape to both sides of the groove if a tighter fit is desired.\u003c\/li\u003e\n\u003cli\u003eCheck if your gooseneck can be supported by two blocks, from either side, for greater support\u003c\/li\u003e\n\u003cli\u003eWith one block still serving as an alignment reference on the mast, position the second block so it holds the gooseneck in place and aligned to the mast bend and drilled holes. Tighten the block\u003c\/li\u003e\n\u003cli\u003eIf your gooseneck can be supported by a second block on the other end, move a free block to this position and tighten. The gooseneck should be firmly in place for drilling.\u003c\/li\u003e\n\u003cli\u003eOptionally, for added stability while drilling, place a few dots of cyanoacrylate glue to hold the gooseneck in place, or temporarily tie it down with zip ties.\u003c\/li\u003e\n\u003cli\u003eCarefully drill the gooseneck and mast as instructed by the manufacturer.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: 3d printed in PLA which is a bioplastic with low melting point and becomes soft at 50°C.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFixing screw: M6 nylon thumb screw\u003c\/li\u003e\n\u003cli\u003eDimensions: 34 mm cube\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SailorMadeRC","offers":[{"title":"Default Title","offer_id":57678270824783,"sku":"SM-DRILLMAST-11","price":10.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3010\/7727\/files\/SM-DRILLMAST-11.MAIN.jpg?v=1778626251","url":"https:\/\/sailormaderc.com\/products\/mast-drill-guide","provider":"SailorMadeRC","version":"1.0","type":"link"}
