I am attempting to replicate router cuts

enter image description here

I made a template and am having difficulty finding router bit that works.

My template sits on top of the triangle. I tried using a flush cut pattern bit and the depth is set correctly. That works fine but the top bearing seems to hold cut 1/4 inch from where I want the cut.

It does not seem to cut flush with my pattern. The resulting cut is too narrow. What do I need to do?

  • Guess picture did not come through. Sorry. Hopefully explanation gives the idea of my problem

  • Use a photo hosting site like imgur or postimage; put a link in your edited post; someone will edit your post to include the pic. You might also include a pic of your bit. Commented Jun 20, 2019 at 2:48

    Cut your template hole larger by 1/4".

  • Thanks for suggestions. I tried another flush cut bit which did ride flush. Now I am not able to get cutter to clear 3/4 inch thick template. Plan to try raising bearing on bit shank by 1/16 inch Commented Jun 21, 2019 at 2:09
  • Yeah, the first time I tried template routing, I had the same problem. I made the template too thick. In the future, try making your templates out of hardboard or 1/4" thick MDF. Those are my current go-to materials for shop made router templates. Commented Jun 24, 2019 at 14:25

My guess is that you do not, in fact, have a flush cut bit, but rather a hinge mortising bit, such as the Freud 16-560, that is designed for templates that are slightly oversized. enter image description here

You can either get a proper flush trim bit, get a different bearing for the bit to make it cut flush, or modify your template to account for the offset.

  • Links to pictures are not necessarily persistent so I recommend directly inserting a picture in a post. Thanks

  • @ashlar I actually linked to a product page, not an image...I'm not really sure that an image would get the point across. It's only got a 1/8" offset, so it would be hard to see. Maybe I should just remove the link altogether and cite the model number instead? Commented Jun 21, 2019 at 16:02
  • IMO the link is fine and will hopefully last a long while. Adding the image is insurance against it disappearing.
