Fly Fishing & Fly Tying Magazine Review

In his recent review of August 2011 Magnus Angus wrote of Gray's Needle Tubes:

... slender, gleaming tubes; utterly functional and very tempting!  ... these are extraordinary in a couple of ways - slimmer than any straight tubes I have seen for sale - stainless steel which is both hard to find and hard to cut.

... flies tied on these tubes are not like heavy bulky conventional tubes, these are light and sleek, cast easily and can be controlled by a sink-tip or poly-leader. Want to fish deeper - use a faster sinking line. In other words these are modern tubes for modern fishing techniques which emphasise easier casting and employ sophisticated modern fly-lines to determine fishing depth.

As a fly tyer the proportion, neatness and finish of these tubes and the neat finish I can achieve on them appeals directly to the satisfaction I get from fly tying. And stainless steel tubes are about as tough as fly tying tubes get - so my carefully tied flies should fish a little longer. Then as an angler, the slimness of these tubes makes me think of clear water and sea trout. The shorter tubes seem ideal for those wee speck-like flies for low flows, longer tubes for faster water or fishing into the dark ..."

Needle Tubes

Gray's Needle Tubes are made using very fine stainless steel tubing, the type used in the manufacture of hypodermic needles. Our Needle Tubes are the thinnest plastic lined metal tubes available for fly tying. We have now added a second range of Needle tubes. The new tubes have an outside diameter of 1.8 mm, and inside diameter of 0.60 mm, allowing the use of leaders of 30 pounds breaking strain or more, but if using a silicone or PVC extension (bore 1.5mm) to retain the hook and knot, a maximum of 20 lb nylon is recommended. The 1.8 range of Needle Tubes, made in Scotland by Grays of Kilsyth, are now available in our online shop in the following lengths: 10mm, 15 mm, 20 mm, 25 mm, 30 mm and 35 mm

Dressing Gray's Needle Tubes

To dress the needle tubes, the tube should be secured in a suitable Needle Tube Vice

The tube body may be dressed in the normal way or left undressed to give a simple, very slim silver fly body, as shown in the examples below.

A short length of silicone tubing is then used to connect a hook of appropriate size, treble, double or single.

If a fly longer than 40 mm is required, two tubes may be joined in tandem by a length of the silicone tubing provided to produce a fly of anything up to 8 cms in length.

The new 1.8 mm range of Gray's Needle Tubes adds to the options created by our 1.5 mm original needle tube range, allowing the salmon fly tyer to make tube flies in lengths from 10 mm up to 40 mm (tube length). Since the new tubes have an internal diameter of 0.60 mm, they can accept leaders of 30 lbs breaking strain nylon or more, and can be used for larger fish, such as salmon, steelhead and sea trout, in heavier water. However, if using a small bore (1.5mm) silicone or PVC extension tube to retain the hook and knot, a maximum of around 20 lb nylon is recommended. I would also recommend a knot which results in the tag end pointing to the rear of the hook, e.g. the Trilene Knot. This makes it easier to insert the hook eye and knot into the silicone sleeve. Being made from fine polished stainless steel, the kind used in the making of hypodermic needles, needle tube flies sink more readily than plastic or aluminium tube flies but fish a little higher, and more attractively, than the heavier copper and brass tubes. Needle Tube Flies would have a comparable sink rate and similar slim profile to flies dressed previously on Waddington shanks, but with the important benefit that the hook is easily changed on the needle tube fly. Needle tubes are also much easier to dress than Waddington or snake lures.
