Project Story:

Rounding Jacks are used to cut the brim felt to size on fedora, western hats, cowboy hats, and several other styles. The brass adjustable curve on the front is placed against the crown, and then the cutter is moved in a rotation around the hat, keep the pressure against the crown. Setting the blade to the proper size is done by adjusting the cutter to the desired cut size, and then tightening the brass knurled knobs.

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 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.

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.

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.

These tools are sure from another century. The quality and attention to detail is something you hardly see anymore. Maybe in some antique tools. It just has to rub off on the craftsmen who use these tools to make hats.

I get to see the vintage ones quite often, and they were cheaply built out of soft pearwood or poplar, always broken, split, missing parts, and pretty rinky-dink.

Still, they sell on eBay at pretty high prices since they are so rare. I’m hoping to give people another option.

I restored one this week for a guy that bought one on eBay that was missing a critical part. He’s going to resell it with my name on the restoration and new part fabrication for it, and then use the money it raises toward one of my new ones. I hope he starts a new trend.

I’ve also been doing some preliminary planning for making a line of one-of-kind woodworking Block Handplanes, with the same goal in mind. Functional-Art for the discriminating woodworker. I hope to get that started some time later this year.

From Kansas, where we are fixing the rounding jack world, one at a time,
