Customer Testimony Printed with Permission:
“I meant to email you sooner but things have been crazy around here. I love the rounding jack both aesthetically and functionally. It’s a new tool to me so it has taken a little practice; you have to be sure the hat doesn’t turn while you are sliding the jack around but that isn’t a problem. The cut is smooth and perfect. Thanks again for your great craftsmanship and for getting it made so quickly. I am sure it will be a useful tool for many years to come!”

This project is a Rounding Jack for a custom “Pirate Hat” maker in the Kansas City area so that he can cut the felt brims on the hats he makes and sells on his website and at festivals.
The owner of Pyrate Trading Co. (PTC) found my Rounding Jacks on the lumberjock postings a few weeks ago and placed his order for one of my production models.
His Rounding Jack is serial number #2008-06
The wood used on this project is Kansas Black Walnut. The rest of the parts are yellow brass.
Display Stand: The display stand is designed to sit on the hatmaker’s work bench and hold the cutter when it is not being used. The retractable blade can remain extended this way between uses. This particular stand shown in the photos is Kansas Black Walnut. This display stand is meant to make the whole project look like a functional-art sculpture, while it serves it’s functional purpose of the Rounding Jack safely.
The Adjustable Brass Crown Band on the front of the cutter is used when the brim is to be cut wider on the sides, than on the front and back. By adjusting the curve of the brass band, the cutter is pushed away farther on the wider curve of the crown sides.
The inlay piece is synthetic ivory with Pyrate Trading Co.’s business logo scratched with a knife by hand in a scrimshaw style artwork.
To make the cut.
The blade guard knurled nut is loosened, the blade dropped down and the nut retightened. The slider nuts are loosened and the desired cut width is indicated by the pointer, and the slider nuts are tightened. The hat is placed on a wood crown block to give a firm resistance to the pressure being applied with the cutter, and the brim is placed between the bottom brass plate and the bottom of the cutter. Then, depending on whether the hatmaker is a Clockwise, or a Counterclockwise cutter, the Rounding Jack is slowly moved around the contour of the crown while pushing the cutter toward the center (head). Felt Hat Blanks are very expensive, so after the cutting is complete, a big sigh of relief is heard from the hatmaker.
