I was checking to see how a 3/4" dog hole would look in a vise jaw made from two 3/4" pieces of plywood. Just clamped for the test, but would be glue for the real thing. Interesting to see the hole opened up. And luckily no splitting, but do you think it would work as an actual vise jaw? This is for a Veritas quick release front vise, so the jaw is only supported in the middle.
I’m not familiar with the term dog hole. You mean like what is shown in this image?
What is the purpose? How is that you did accidental?
Yes, they’re for “bench dogs”, which let you clamp boards against the top of your workbench. I only recently learned about them myself!
When I was drilling the test hole I wasn’t thinking about how it would look to open up the two clamped boards afterwards, so it was just a fun surprise to see the shape of the inside of the hole revealed like that.
