Default which direction

Using a table with router - I want to rout out the black circle - completely through the board. The board is 3/4" thick.

Using a pattern for a guide with a bearing bit.

So the question is - after drilling a starting hole (not plunging) which direction should I go CW or CCW

The work would move clockwise around the bit for the bit to pull it against a female pattern.

work ->
<
v bit ^ work v
>
< work

That said I'd cut all the way through within 1/8" of the pattern with a sabre saw then clean it up on my router table.

Wood grain in solid lumber is another complication. Since you don't want to route into the grain like this

work ->
\\\\\\\ grain
<-
bit

you'll want to flip the work in the pattern or flip pattern + work and switch to a flush-trim bit where the grain reverses direction so you're running like this

work ->
////// grain
<- bit

parallel to the grain is fine, cross-grain is fine, it's just a problem in between where it starts acting like a feather board pointing in the wrong direction.

Hi Paul - don't forget to control that center piece. Once it is cut free from the board the bit is liable to throw it at you.

The problem with experience is I usually get it immediately after I need it.
