cutting out shapes with a router
I would like to cut numerous wood pieces that are identical in shape
and about 6" long 3 inches wide. I want to cut them out of 3/4" hard maple. I made myself a template from 1/4" plywood and tacked it to a piece of the 3/4" maple. I then trying using a cutting bit on my router table to cut out the shape. On the top of the bit is a small wheel that I used to roll along the edge of my template. The whole idea sounded easy enough to me until I tried it. The bit would periodically grab really hard and sometimes it would break chunks of the maple off...scary! I tried going slower, faster, etc., but could never get it to work. My Craftsman router table and router only run on one speed so I can't adjust it. I am guessing that the problem is in the blade. Does anyone have a suggestion for me as to how to make this work? Please keep the response at a "novice" level...I am most certainly a beginner. Thank you! II |

cutting out shapes with a router
Since nobody else has thrown out an answer, I'll throw in my $0.02...
I suspect what your problem is that the router bit is catching in areas of wood-grain change, and pulling off chunks of your hard-earned wood. Your solutions to the problem would be: 1) Cut out the rough shape using a jig saw or bandsaw. Try to stay within 1/4 to 1/8 of an inch of the shape. This will help prevent the bit from getting too much material to grab onto. 2) In areas of grain change, be prepared to move the router the opposite way around the pattern. If you look at the way the router bit turns, the direction you're moving the router, and the grain of the wood, you'll see that there are probably areas that you're going against the grain, and the router bit will basically pry up chunks of wood, ruining your pieces and leaving you with splinters. Having said that, routing with the grain ("climb cutting") can be dangerous, as it may cause the router to move in an unexpectedly quick manner, as the bit basically accelerates the router in the direction of travel. Here's an article that may help: http://www.newwoodworker.com/clmbcuttng.html (found with a google search). Have fun, and be safe. If something makes you feel uncomfortably unsafe, there's probably a reason for it, and you should stop and see if there's another way. There's almost always multiple ways to accomplish something, and sometimes the scary ways outnumber the safe ways. Clint wrote in message ups.com...

II Take a stack of maple samples and mark on the top piece using the template the shape you want to cut . cut as close to the line as possible with a bandsaw as many as you are comfortable with at a time. then try the same procedure you started with . You probably tried to remove too much with the original procedure. by the way work against the cutter not with it [which will throw the piece across the shop... |

I made myself a template from 1/4" plywood and tacked it to a piece of the 3/4" maple. You need a starting pin to brace against as you snuggle into the bearing. Library or used book shop text on basic routing would describe it best, though in essence it's a pin close in toward the bit, against which you place your piece, using it as a fulcrum to move into the bit and bearing. http://www.patwarner.com/ for a good bunch of routing information. Even better is to use the starting pin and a holding jig. Can be just handles on a sturdier template, or a commercial one like http://www.leevalley.com/wood/page.a...,41780&p=41780 |

cutting out shapes with a router
You guys are awesome! I have never been around someone that worked
with wood in my life and all I have learned by trail and error on my own time. I will investigate all the links you guys have provided, thank you very much for your time!!

cutting out shapes with a router
Great advice. I have cut out hundreds of pieces with the bandsaw in the
last couple years and run them through the router. For months I ran the pieces in all directions on the router because I didn't know better. After some reading though I realized just what you wrote above Nate...to only go against the bit. I worry about the router everytime I use it though, it's a dangerous tool. I intend to buy some push pads right away after reading the info that Clint posted. I think at this point I will try and cut out most of the shape with a bandsaw and then take it to the router to see if that works. I will be very careful! thanks again! II |

A assume for a bit mounted in the table you'd want to use a spiral up-cut and not a spiral down-cut, right? Thanks |

cutting out shapes with a router
I use the right hand thumb and curled fingers as a mnemonic for
feeding into a rotating bit. Thumb represents the router bit projecting out of the base/table. Thumb pointed up means counterclockwise bit rotation therefore stock is passed in front of the bit from right to left INTO rotating bit cutters. Handheld with thumb pointing down cutting edges are clockwise rotation and router is passed in front of the wood from left to right. When table is used for edging long and end grain the end grain edges are cut using a climb cut with stock held FIRMLY to avoid be torn out of my hands, for about 1" or 2" then conventional direction for balance of that edge.
