Have a dumb question - tool sweeps

[ten99j4]

This probably will sound rather silly and I may really feel dumb when I find the answer. What do the numbers represent when describing a tool. Ex. #11 gouge or #9 gouge. Obviously, if there is a measurement, I know what that means, but not the designated number.

Those numbers represent the "sweep" of the gouge, usaually. Sweep is really only the diameter of a circle that the gouge will make if you put it straight down on a piece of wood and rotate it 360 degrees.

A number 1 sweep will be almost flat and a number 11 will be rather circular. Hope that makes sense.

The other numbers associated with gouges refer to the width of the blade, either in inches or millimeters. Some will list 3/4 by 10 fer instance which would be a 3/4" wide gouge with a #10 sweep, and a 25/10 would be a 25mm gouge with a #10 sweep.

That makes sense. I haven't done enough with gouges yet to judge the sweep that I need ahead of just grabbing one by sight and trying it.

Thanks,

Here's a link to a chart on "sweeps". It also shows the differing number systems for V tools.

You all are awesome. I was hesitant to post this question, but I'm glad that I did. Visual aids are always welcomed!
