8 Quick Step Procedure on Using the Finger Joint Router Bit

  • Step 1: Arrange the finger joint router in a bit body that is aligned to the thickness of the piece of wood that you want to be cut or shaped.
  • Step 2: Make sure that the wood that you want to get the work done is placed in a coping sled. This would make sure that the wood will stay in place and it won't dwindle while you try to make a cut from the finger joint router.
  • Step 3: Make a small center mark to find the exact center point of your material. This will be your guide in creating the spaces or the shape that you want before you have it cut.
  • Step 4: Check if the mark that you made aligns with the finger joint router and its edges. If not, you could always adjust it either you raise the joint router or you lower it.
  • Step 5: Set a fence angle by using a ruler. You must do it at the bottom of the joint router.
  • Step 6: Ready your fence on the working table and have it protect the joint router before you start running your wood with it.
  • Step 7: Lock the fence as soon as you have set it up, so it doesn't move and get in the way of your project.
  • Step 8: Slowly run the wood to the finger joint router using your coping sled to make a precise space or shape on the wood that you are trying to get done. The first cut must be faced up, while the next cut has to be facing down.

In the event that your wood pieces don't fit, you can always make an adjustment.

To do it, you must determine which part is too thick. From there, you could always change half the distance that two wood were originally set.

This will solve the issue and you will have two pieces of wood joined perfectly like a puzzle piece meeting another puzzle piece.

Finishing Touches

It is not enough that you just leave your project without doing some finishing touches. This process is especially done in woodworking.

  • Step 1: Get a miter gauge or even a push block could work in feeding the pieces that you just finished cutting.
  • Step 2: Glue them together to make sure that they don't fall apart or to ensure durability.
  • Step 3: Sand the two pieces of wood so they look perfect and presentable.

Here are some of the things that you must be reminded of before using the finger joint router bit

  • 1. Measurement: Always keep your wood measurement precise. Although you can always do some adjustments if ever you mess it up, it is still best to be exact when it comes to your measurements. This will save you time and energy and even money.
  • 2. Preparation: Make sure that all your equipment are ready before you start dealing with cutting your wood with a finger joint. Always have your materials in places where you could easily reach them.
  • 3. Follow Instructions: This may sound like a cliche but it is often taken for granted. Don't assume you already know how to use this when you haven't used it before. It may really look so easy but without the right directions for you to follow, you might actually cause some accident on your own.
  • 4. Accessories: You need to wear some protective glasses or goggles for this activity, so your eyes are safe from wood dust and other things that might get in your eyes.
  • 5. Router Plugs: Keep in mind that the router has to be unplugged before you could do any alteration in the bit configuration.
  • 6. Router Table: It is a must to own a router table when using this bit. Others would dare to use a handheld router, which is not safe. Don't be one of those.
  • 7. Spacer: When it comes to slot cutters, never forget to use a spacer between them to make sure that all the ends and sides are even.
