It’s very easy to make.

The rolls are made from hardened steel and i have buy them by

First we make the T part.

My part is 100mm by 50mm

I cut off two pieces. 80mm X 17mm

Measure the roll

The cam is 0.1mm thicker than the roll

Now we gonna make this part.

We need two of them.

The dimensions are
100mm X 20mm X 15mm

First we cut of one side.
The hole is height 17 mm width is the thickness of the cam + 0.05mm

At the other side of the block we do the same but then with the thickness of the roll + 0.05mm

At the side of the cam we chamfer the edge. It doesn’t matter how big the side is.

At the other side of the block ( where the roll must come ) you must chamfer 2 sides

At the cam side we drill a hole of 6 mm through the whole block

At the side of the roll we drill a hole in the upper part with 6 mm and with the same drill we make a center in the lower part. There we must use a drill of 5mm to make m5 screw threat

Clamp the two parts together like this. ( look to the 2 chamfer edges on the cam part. ) and drill a 12mm hole in the middle through the blocks

IMG_5571

Turn the blocks for 90 degrees and drill a 10mm hole through the 2 blocks like this.

IMG_5572

Make 2 parts like this. round 11.8mm and 20mm long. The hole is M6

Assemble the parts and enjoy your knurling tool.

Yes it’s ready.

Tip : Use a spring between the two blocks.
