Arbor Knot (Canadian Jam Knot)
Arbor Knot (Canadian Jam Knot) TyingPass the fishing line round the arbor. With the free end, tie an overhand knot around the line. Then tie a second overhand knot in the free end to act as a stopper. Finally, slide the knots down tight against the arbor.
Arbor Knot Details
Uses: The Arbor Knot is used to attach the fishing line to the "Arbor" or "Spool Center". In fact the Arbor Knot is really based on a noose knot and, therefore, pulling tightens it. The same knot is used in Bushcraft under the name Canadian Jam Knot where a light rope, e.g., paracord, is being used to compress a load such as a sleeping bag or is used as the first step in creating a lashing.
Tying it: When the Arbor is accessible, the easiest way to tie the Arbor knot is to create a Noose, drop it on the Arbor and pull it to tighten it. If you make a Slip Knot by mistake it will just pull undone. Alternatively, as shown in the animation, first pass the free end around the Arbor or the load; then use the free end to tie the first overhand knot around the line.
Second Overhand Knot: The extra Overhand Knot in the Tag End is tied close beside the first one. It is essential: as the knot is tightened it snugs down against the Arbor.
Improved Version: Some fishermen wind the loop two or three times around the Arbor before making the first Half Hitch. This increases the friction, which may be useful on a highly polished reel. The direction of these turns is critical. They should be wrapped as though tying a Tensionless Knot: rotating the reel should tighten the wraps.
Advantages: The Arbor (Canadian Jam) Knot) is simple, easily learned and effective.
Disclaimer: Any activity that involves ropes is potentially hazardous. Lives may be at risk - possibly your own. Considerable attention and effort have been made to ensure that these descriptions are accurate. However, many critical factors cannot be controlled, including: the choice of materials; the age, size, and condition of ropes; and the accuracy with which these descriptions have been followed.
