12. Chipped Grain Tear Out Usually a result of cutting against the grain or planing wood with knots or excessive amount of cross grain Chipped grain can also be caused by dull knives or misaligned chip breaker Often chipped grain can be avoided by slowing down the feed rate and by taking shallow cuts If those options do not work inspect your lumber and determine if its grain pattern is causing the problem If the wood does not show substantial crossgrain inspect your knives for sharpness and inspect the chip breaker for proper alignment Fuzzy Grain Raised Grain Usually caused by surfacing lumber with too high of a moisture content Sometimes fuzzy grain is a characteristic of wood such as basswood Fuzzy grain can also be caused by dull knives or an incorrect grinding bevel Check with a moisture meter If moisture is greater than 20 sticker the wood and allow it to dry Otherwise inspect the knife condition Glossy Surface Usually caused by dull knives taking shallow cuts at a slow feed speed Surface gloss will usually be accompanied by overheat ing Lumber will often be scorched and eventually damage to the knives will occur If the knives are sharp on inspection increase feed speed or cut ting depth Snipe Occurs when board ends have more material removed them the rest of the board Usually caused when one or both of the table roll ers are set too high Can also be caused by the chip breaker or pressure
