if you're making a project that requires awide board say, you're making a table top, you have two options. you can either use plywood and cut it downto whatever size you need or you can use solid lumber
woodworking bench top thickness, which means you're going to have to take individualstrips of wood and join them together on their edges. but the challenge with using solid lumberis that when you buy boards, they're often slightlywarped or the edges may not be perfectly square.
when you try to glue them together, you don'tget a perfect seam between the two. so to join these two together, you need to"joint" the edges.jointing the edges is just a woodworkey way of saying, "square them up". the easiest way to square up those edges isto use a dedicated tool called a jointer but a lot of hobbyist woodworkers can't reallyjustify the expense, not to mention the space it takes up. but a lot of us do have routers. and if you have a router table you can edgejoint on it. even though i've shown this in other videos,
i thought it would be nice to have a meremini specifically about this procedure. the only trick here is that you need the leftside of your fence to stick out slightly ahead of the right side of your fence. i have a split-fence system on mine that ican remove and put in a couple of washers as spacers. this will shim it up. if you don't have a split fence, you can justclamp on a thin strip of plywood to the left side. i've put a straight bit in my router
and i've raised it up slightly above the thicknessof the wood. now i can bring my fence forward to wherethe left fence is in line with the cutting blade. i'll use a straightedge to check it. the key to getting a good square cut is themethod you use to push the board through the router bit. i'm going to put a little pressure on thisright side just to get it started but once the board it through the router bit,i'm going to transfer the pressure to the left side fence and keep it here throughout the rest of thecut.
and that gives me a perfectly square edge and usually you're only going to joint oneedge of a board. if you need the board to be parallel, you can't just flip it around and joint theother side. what you need to do is, take that jointededge and run it along the rip fence of your tablesaw and that will make sure the other side itperfectly parallel with it. and once these are glued together, that seamwill be practically invisible.
