You are absolutely correct!! Well...except in the place you aren't...quite.
The L1 is a bit different than 'to the start of the taper'.
Also commonly a reason for confusion in understanding needles.
THe L1 is
not the distance from the clip to the start of the taper.
L1 is the distance from the clip-end of the needle (I'm sure that's what bradf meant..not the clip but the clip
end..the blunt end! ;) ) to the point where the needle diameter is 2.515mm. That number is generally referred to as the 'magic number'.
You can see there will be considerable difference between the taper start and the point at which the magic number happens with different angles of taper and starting diameters.
Where this is important: Consider two different taper º with the same L1 and diameter. The faster taper will get to 2.515mm sooner than the slower taper, so the faster taper needle will have to START tapering LATER (further from the blunt end) than the slower taper needle.
Cool, huh?
You can see that the taper hit in throttle position will change with a change of needle angle and the same L1. That's why (fer instance) a common clip position for the DEK is -4.
A slower taper needle can be somewhat richer toward the bottom of the throttle.
Now class...why is that?
Not that it matters a whole lot...but you know the angle numbers? They are measured in degrees and minutes. Each º is made up of 60 equal parts called 'minutes.' For example, a 'B' needle taper is listed as 1º15' (that would be 1 1/4º) a 'C' needle is 1º34' (that would be 1 1/2º).
Yeah...each minute consists of 60 equal parts called 'seconds' too...
Doesn't seem like much...but figure the % of change and then it is clearly quite a large difference (20% change from a 'B' to a 'C')
Howwzat?
Oh...I
do expect correct answers on the above taper question.
