Hello everyone,

I am creating some plaques to hold poker chips. Poker chips have a diameter of 1.535" to 1.575". I can't find a drill to make the recesses for the chips so I am going to make a template and use template guide (the thingy that fits around the bit and rubs up against the template) to make recesses in the plaque to put the chips in. Most other poker chip displays use a hole punched in foam rubber to hold the chips. The foam rubber does not have to be so critical in it's diameter dimension.

In a couple of sources I have read or seen on DVDs, it is advised that the same edge of the template guide should be used to maintain equal distancing. I know that you can center the bit and do all that but it still seems that always having a single point of the template guide rub the template is the way to go. Expecially if I am trying to maintain some close tolerances.

Now for my question. I am thinking of making a 3 foot diameter turn table as a work surface. Then it would be easer for me to turn the work versus rotating the router as I go around the 1.575+" hole in the template. I would put a small motor on the turn table and just stand in one spot holding the router while the work turns under it. Then I would reposition the work so that the next chip holding recess is at the center point of the turn table. Rinse and repeat for the 20 to 40 recesses I need to create.

Any comments will be very helpful.
Thanks,

Terry, you can get 1-37/64" (1.578") Forstner bits if that's easier. They'll give a real clean, flat bottomed recess. Have a look at

Post a pic when you've finished.

I would agree with nzgeordie on this one..


Routers do make neat holes but they also make tons on clips
The Forstner bit will pull them right out unlike the router bit..

I guess you are going down 2" or more, that's hard on a router bit, not to say any thing how many times you will need to plunge the bit in and out of the hole,,

Plus with the Forstner bit when the hole is drilled out you and can go back and take off just a bit of the hole ,so you can get the chips out easy...with two fingers and see what you made in the poker game.. with just quick glance...

The bit mentioned above is likely 40mm which is actually 1.5748". Lots of 40mm bits are available, mostly in industrial carbide boring bits like this:

Hmmm, I must be missremembering the diameter I need. I have a 40mm forstner bit and it is a hair too small. I will recheck tonight.

Thanks for the replies.

Hi Terry


40 mm = 1.574798

most poker chips are 1/8" x 1-9/16" ,,,1.5625" , 39.6748 mm

You want to make holes a bit larger than the chips. Otherwise, it could be hard to get them out.

Boy, I am getting old. The Forstner 40 MM bit was too large and I wanted a tighter fit. Not totally tight but better than the hole the drill would give me. I was going to use the router for other things on the plaques so I decided to make the recesses for the chips with it.

The actual dimensions are 1.545 to 1.560. The hole the 40mm bit left was way too big for the smaller chips. Enough to have quite a gap at the top.

So now back to my turn-table. Anyone ever tried or seen such a contraption? Any advice on using something like it?

Thanks again,

Terry firstly I do not see the need for the holes to be produced to suit the degree of accuracy.
Here is my interpretation on how I would go about solving the problem.
First decide on how large the hole is to be inserted. Then decide on what cutter and template guide you are to use.
Simply add the diameter of the hole required to the difference between the guide and cutter and produce a circular cut-out in say a square template with the circle cutting jig.

As an example in Metric
Size of hole required= 39mm
Using a 40mm template guide with a 10mm cutter

Therefore size of hole in template is 39mm + {40mm-10mm} = 69mm

Should you change the size of the chips you will require a new template with a different cut-out.

Terry I hope this has been of some help, unfortunately I will be away for the next 10 days but I am sure my star student Harrysin will be able to assist you with any further questions.

Terry, why not post a sketch of what you have in mind, then I'm sure we can give you a suitable method of construction.
