I can use a hole cutter, hopefully to cut through hardwood. But
regular wood might work. There will be no hurry to make the cuts.
Accuracy is important.

The outer diameter of the wooden wheels will be about 1 inch. The
center hole will be 1/4" to 5/16".

Hopefully I can make both cuts while the wood is gripped firmly in
place, simultaneously or one at a time.

Thanks.
