Project Story:
Rounding Jacks are used to cut the brim felt to size on fedora, derby, Panama, western hats, cowboy hats, and several other styles.
Economy/Hobbyist-Hatter Model:
Since I first introduced my Rounding Jacks for sale, there has been a good amount of interest in them. During this time, I’ve been asked many times if I could come up with a less expensive version of the tool, mostly suited to Hat Makers that make hats as a hobby, only needing to cut a few hats a year.
What Makes This One an “Economy” Model?:
I developed this version of my brim cutter tool with a smaller capacity brim cut. Also, this version does not have the adjustable brass crown shoe on the front of the cutter.
Laser Engraved Ruler:
I have converted over to using Custom Laser Engraved Rulers for each of my Rounding Jacks. To highlight the markings, I use ivory colored acrylic paint.
Direction of Cut:
This particular Rounding Jack will cut in the Counter Clockwise path. If you would like to go the other direction, just let me know and I can build a Rounding Jack to go the other direction. They are not reversible, as that would take another more expensive step in the design of the blade guard, so it is cheaper for us both if I just make the cutter to cut the direction you want to use it.
Display Stand: The display stand shown in these photos is available at an additional cost, and 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 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 holding the Rounding Jack safely.
To make the cut.- The blade guard Thumbscrew Nut is loosened, the blade dropped down and the nut retightened.
- The slider thumbscrew 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.
