How to route circular depressions
« on: August 05, 2019, 02:16 PM »
Ok. As some of you may know, I'm completely lost when it comes to using routers.  Is there an easy way to route circular depressions? Or do I need to make some kind of jig.  What I'm looking to make for some friends is in the image below.

What does the 25mm sign refer to?

One option is to make a simple template out of hardboard or MDF drilled with an appropriate forstner bit.  Then use double stick tape and rout with a top bearing guided pattern bit.  Making multiples if needed would then be easy.

Does it have to be done with a router? Can it be two layers?

   If those are 25mm diameter, get a 25mm forstner bit. Drill all the way through a piece that is the thickness of the depression depth (1/4" ?).   And then just layer it on top of another piece.

25mm depressions/openings.   I thought about doing it in layers and forgot about buts with bearings for an MDF template.  I can probably just use a forstner bit either way. The key will be to keep it as thin and light as possible, as these will be used for a table top war game.  Thanks for helping out a woodworking idiot

I think the plan detailed by Seth and Dick is a good one. Using a pattern bit is easier than you think  (if you haven't tried that before) as long as your template is properly attached.  Do you have a spindle sander? If so, you will likely want to run the holes around the spindle for a quick sand after drilling with the forstner bit.  Other than that, I think once you get the set up taken care of, you should be able to make a lot of these fairly quickly.
