Customer Testimony Printed w/ Permission:
Hi Mark,
I picked up the rounding jack from Customs yesterday, and just cut
the first brim with it. Thank you so much for this wonderful tool! I
never dreamed that it would be so easy to work with, almost cut the brim
itself! Thanks for this great piece of craftsmanship.

Have a nice weekend!
Best regards

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.

Now, Mike, if you want to help me, you just need to buy some hats. If you need any references on where to buy a good one, let me know. The more hat buyers there are, the more hatmakers there will be, and the more Brim Jacks I can build. See, the circle of life.

I hate to think of the skin cancer that is headed toward my generation who have only worn baseball caps with our ears exposed. I quit doing that several years ago, but it will be a hard lesson for the rest of us I fear.

Thanks for the comments everyone,
M

So… have you made any hats yet? I wanna see them when you do. Might not be a lumber thing, but the knives are bone and steel, so hey, work it.

My money guy has about 2 dozen hats of various shapes and styles, so I’ll pass the link on to him.

Hey Mark;

It is very good to see you’re finding new / old products to work on. This prototype you have shown here will work for cutting circular shapes in veneers.

It is somewhat like the cutter I made to cut veneer borders on table tops. (although mine were pretty simple in design and function, and were not adjustable).

Item number 7. Wouldn’t that be a Hat Puller Downer?

NIce stuff.
