   That means that it will be taking a very fine shaving - longer to plow the groove but a smooth result.

   A tight mouth, on any plane, will mean shavings need to be thinner, or the mouth will clog, and youll be clearing it a lot. That means more passes with light cuts. It generally means a finer finish.

   I plowing grooves or cutting rabbets, I generally don't care about finish quality. If the bottom of a groove or rabbet are a little ragged, that's OK with me.

   Wooden or metal plow planes don't even have a throat. Their skates are thinner than their blades, which means it's harder to clog.

   Make your grooving plane with a tight mouth, then put it to work. If it clogs too often, or if it takes a bazillion light passes to make a groove, open the throat up a little. It's easy to open a throat, and harder to close it.

   Thanks John. Makes sense.
