This project is a “brim cutter” that hatmakers use to cut the brims of Fedora and Western style hats. Actually, any style of hat can be cut, with a brim size ranging from 1.25”-8”.
The wood used on this project is Kansas Black Walnut. The rest of the parts are yellow brass. The inlay piece is synthetic ivory with Steve Delk’s business logo scratched with a knife by hand in a scrimshaw style artwork.
I enjoy mixed-media work, and making things that are pretty (handsome) and useful.
Project Story:
Few custom hatmakers can say they made history, but Steve Delk and his business partner Marc Kitter are two that can. After spending months of hard work researching and studying the old Indiana Jones hats from the early 1980’s movie trilogy, they designed and built all of the Fedoras for the new ”Indiana Jones and the Kingdom of the Crystal Skull” Spielberg movie.
They told me that they made 48 hats in all for the movie, some were souvenirs that the production staff kept, as well as the ones used in the filming.
Now, they are selling copies of the exact hat that they made for the new movie. If you would like to order one of Steve & Marc’s Indiana Jones’ hats, you can contact them at their website:

Steve Delk found my Rounding Jacks on the lumberjock postings a few weeks ago and placed his order for the first of my production models. His Rounding Jack is serial number 2008-03 (the first two serial numbers are my protypes). A few days later, his partner in Germany, Marc Kitter, ordered one, serial number 2008-05.

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 Red Oak. 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.

Beautifully done Mark. I’m a fan of all your stuff. You just know automatically when you see DeCou on the post, you’re gonna get something special. Now I’ll get to what I want (wink, wink). I have stared at all these hat projects you’ve posted and I just can not figure out how this brim cutter is supposed to work. Can you please, please, please, post a picture of it in action or an illustration or something for hat dummies like me? Please?
Thanks, (Did I say please?)
