A couple of leaders from Sweden

Dear Mr Joergensen

Some years ago I contacted you and asked if you had the formula for HL Leonard hand-tied leaders. You were kind enough to ask around, but could not find any.

Last year I was able to secure two original hand-tied HL Leonard leaders in their original package, 9 ft 4x and 9 ft 5x. I have now measured the diameter, by micrometer, on the different sections as well as the length of the sections. I enclose the measurements in case you are interested in including them into the LeaderCalc.

4x

Diameter (mm)	Length (cm)
0.50	44 (including perfection loop)
0.43	52
0.37	47
0.34	47
0.265	47
0.18	47.5

5x

Diameter (mm)	Length (cm)
0.48	44.5 (including perfection loop)
0.435	45.5
0.39	46
0.31	47
0.225	50
0.16	50.5

Considering that these leaders are hand-tied I am not surprised that the length of the different sections differ.



Kind regards

Johan,

Thanks so much for the leader formulas! I will add them to the tool as soon as I get the time.

No, my guess is that it won't be totally wrong if you were to assume that they were made up of sections of 45 and 50 centimeters - or most likely 18 and 20 inches.

But I'll use your measures and add a note about the origin of the measures and the above considerations.

I have no idea why I am writing to you in English since you probably understand my Swedish as well as I understand your Danish. So let’s switch language (Note: The text is translated below!).

Trevligt att du tyckte tafsarna var intressanta. Jag håller med dig om att tafsarna säkerligen var tänkta att byggas upp av sektioner som var 45cm och en tafsspets på 50cm. Det är så jag knyter mina kopior.

Jag bifogar två foton på tafsarna. Där kan du se att man angivit buttens diameter till .021 vilket skulle motsvara 0,53mm. 4x tafsens butt mätte jag upp till 0,50mm och 5x till 0,48mm. Fast det är ju ingen ovanlighet att tillverkare av tafsmaterial anger en diameter som skiljer sig från verkligheten.

Ha en fortsatt bra dag och tack för en fantastisk site

Nice that you found the leaders interesting. I agree with you that the leaders were most likely intended to be built up in sections that were 45 cm and a tippet of 50 cm. This is how I tie my copies.

I am attaching two photos of the leaders. There you can see that the butt diameter was specified as .021”, which should correspond to 0.53mm. The 4x leader butt I measured to 0.50mm and the 5x to 0.48mm. It is not uncommon for manufacturers of leader material to indicate a diameter that differs from reality.

Have a good day and thanks for a fantastic site
