The DaHo Hollow Spectra Threading Needles are hollow inside, except for the point, so additional material, typically monofilament or fluorocarbon line, can be inserted into the needle. Then, the needle together with the internal mono line is inserted or threaded, into the hollow center section of the spectra braid. The needle and attached mono line is then inserted inside of the spectra a distance of 3 to 5 feet to provide maximum strength of the join. Due to the thick surface of monofilament fishing lines, the endpoint of the spectra must be finished to secure it. The finishing process is done by employing any of these methods:
* Gluing using Line One Adhesive from Jerry Brown Industries
* Combination of the above
The use of any of the methods outlined above ensures the join will not slip before the compression pressure occurs to in the hollow spectra line to hold the joined lines together.
The primary size of the threading needle is the ID, or Internal Diameter, indicating the approximate size of the monofilament line that it will hold inside. The needle size you need is determined by the size of the monofilament line you are using. Typically, these sizes can be found on the spool the line was purchased on, or by visiting the line manufacturer’s website. You will usually want to get a needle that will fit the line you are using, and provide an additional .002" of 'free' space to ease the insertion of your line. If the monofilament line is too large for the needle, you will have to cut it down, which is difficult and time intensive. The needles will easily hold smaller sizes of monofilament lines. DaHo Products offers most typically used sizes in their standard product offerings. Even though they are named for the typical size of mono that they will hold, you should select your needles by the actual size of your monofilament nylon fishing line.
The construction process of the DaHo Hollow Threading needles uses thinner walled tubing to manufacture the needles. This is to assure the overall size of the needle will remain as small as possible while offering the largest interior size to hold the monofilament nylon fishing line. Thinner is definitely better.
