DaHo

DaHo Hollow Spectra Threading Needles have been sized by their length so if a customer has more than one of them, they can stand them on their open end and find the one they want by its length, compared to all the other threating needles. Our smallest threading needle, the 10 to 20# size, has a length of 5.3". Each larger threading needle is .1" longer than the last, with our largest 400 to 500# size being 6.5" in length. When we started, we spent a year gathering all of the requested features for our new needles. Having some way to identify the threading needle sizes was one that was requested many times. Due to their size and materials, the length was the only way to address this request.

The DaHo Hollow Spectra Threading Needles are hollow inside, except for the point, so monofilament or fluorocarbon line can be inserted into the needle. Then, the needle with the internal mono/fluoro line, is inserted, or threaded, into the hollow center section of the spectra braid. The needle, and attached mono/fluoro line, is typically inserted inside of the spectra from 3 to 5 feet to provide the best strength of the join. Because of the slick surface of the mono/fluoro line, the end point of the spectra must be finished to secure it to the mono/fluoro line. This finishing is usually done by gluing, serving,  crimping, or some combination of these attachments, to the spectra line end. This ensures the join will not slip before the compression pressure occurs in the braid of 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 mono/fluoro line that it will fit inside. The threading needle size you need is determined by the size of the mono/fluoro line you are using. The ID sizes of our threading needles can vary up to .002" due to the Stainless Steel Hypodermic tube manufacturing process. This is the standard acceptable size variance of the SS tubes we use to make our needles. As we receive new shipments of needles, the IDs may change up to this .002" size.  It is recommended that you select a needle that is at least .002" larger than your line for ease of use. It can also be difficult to fit an exact size of line into a needle. If you have a problem with your line not fitting into one of our needles, please send us an email and we will analyze and resolve the problem.

 The DaHo Reverse Latch Threading Needles design came from Jerry Brown, a pioneer in the development of hollow spectra fishing lines. We appreciate his design as this product brings some unique features and ease of use characteristics that we try to provide in all our products. Below is a picture showing the ends of the new DaHo Reverse Latch Needle in detail:

In the past, one of the first tools available to work with hollow spectra lines were latch needles that originally came from fabric knitting machines. They are still used today, but our Reverse Latch needle is the only tool available that uses the latch mechanism as it was designed to be used - to be pulled through the line, keeping the latch mechanism closed by the line's internal pressure. Without our 'reverse' use of the latch mechanism, the old knitting machine latch needles have to be pushed into the hollow spectra lines causing to latch to open, and usually resulting in significant damage the line's fibers.

Many of the loop creation and splicing techniques require that a line be released by the tool, while it is threaded up another line. Normal loop splicing needles will not work in these situations as they cannot release a line from the loop.  In those types of operations, our DaHo Reverse Latch Splicing Needles allow the latch to open, releasing the held line, when needed. Also, since they are now attached to our standard 6" needles, so you can now make longer loops and splices without the limitations of the old latch needles. With our Reverse Latch needle, the latch is always the trailing end of the tool.

We are now offering three sizes of the Reverse Latch Splicing needle. The following table shows the details of the DaHo Reverse Latch Splicing Needles:
