The FP-1 is a circle of unfolded CHEMEX Bonded filter paper. In this video a single filter is folded by hand at a table, next to a CHEMEX coffeemaker.

The circle is folded in half to make a half moon, then folded in half again to make a quarter. Each crease is pressed flat. The folded paper is then opened out by hand into a cone, so that three layers of paper sit on one side and one layer sits on the other.

The scene changes to a coffeemaker standing beside a stainless steel gooseneck kettle. The cone is lowered into the top of the coffeemaker with the three layer side turned towards the pouring spout, and pressed down against the glass. Placing the thick side against the spout holds the filter steady and stops it collapsing into the spout, which has to stay clear as an air channel while the coffee brews. The filter is then ready for coffee grounds.

The video ends on a plain card showing the CHEMEX name, the line “Pure Design. Pure Flavor.” and the address chemexcoffeemaker.com.

This video shows the wooden collar and the rawhide tie with its wooden bead being fitted to a full size CHEMEX coffeemaker. It is filmed close up at a workbench, with the coffeemaker standing in a wooden holder. Two hands do the work.

The collar is in two halves. The video opens with a hand holding each half, fitting them around the narrow waist of the coffeemaker from either side so they meet and enclose the glass.

A long rawhide cord with a round wooden bead on it is brought in from the right. The cord is wrapped around the groove that runs around the middle of the collar, and both ends are passed through the bead from opposite sides, so the bead sits at the front of the collar with one end of the cord leaving it to the left and the other to the right. Both ends are then pulled straight out to the left and right until the cord is tight in the groove and the bead is held firmly against the front of the collar.

The two ends are brought down below the bead and crossed. They are twisted around each other and pulled, which makes a knot directly beneath the bead. One end is formed into a loop below that knot, the other end is worked around it, and the two ends are pulled apart once more so the knot closes up tight under the bead.

Finished, the bead sits at the front of the collar with a small knot right under it, and the two loose ends hang straight down together. The video closes on a white screen with the words “Pure Design. Pure Flavor.” and the CHEMEX logo.

This video shows the leather tie being knotted onto the wooden collar of a 3-cup CHEMEX coffeemaker. The coffeemaker stands in a wooden work board with a tray of spare collars behind it. This size takes a plain tie with no bead. Two hands do the work.

When the video starts, the collar is already on the coffeemaker and the tie is already wrapped once around the groove that runs around the middle of the collar. Both ends of the tie come out at the front of the collar, at the small gap where the two ends of the wood meet, and are held together to one side.

The two ends are crossed at the front of the collar, twisted once around each other, and one end is passed through to make a first knot. Both ends are then pulled hard in opposite directions, one up to the left and one down to the right, so the tie pulls tight into the groove and the knot sits flat against the front of the collar.

The two ends are brought back together. One end is folded back on itself into a short loop, and a second knot is tied around that loop. Both ends are pulled apart again to tighten it.

Finished, a small tight knot sits at the front of the collar beside the gap, with the short loop tucked in it, and the two loose ends hang down together toward the base of the coffeemaker. The video closes on a white screen with the words “Pure Design. Pure Flavor.” and the CHEMEX logo.
