Hi Mike,
Your machine is exactly the case in point where the manual makes things much
more complicated than it needs to be. Three charts and a picture diagram just
to figure out what you need? WTF! Writing the pitches on the gears is yet
another great tip. It means more than A-G or 1-9 or whatever one might come up
with.
Frankly I don't like doing math at all and I'm glad the gear label is on the
headstock, nothing beats a picture!

I like just doing the math once. Here is a picture of the gears I have .25,
.50, standard, and the X2 sets. I have 9 drive gears as well. You can see in
the pictures I listed the drive gear 1-9 and the the corresponding pitch that
is capable with that gear set. It will keep you from passing a brain stone
every time you try to get a Lil twisted (lol)

Hello All,
When Legacy came up with the idea of labeling the drive gears A-G and used
a decal on the headstock to match the gears, they really made selecting spiral
pitches easy. Before that point in time, the instructions included with the
machines referred to the gears by the number of teeth. Counting teeth is not
easy but it leads to some more interesting facts about your machine.
Did you know that you can quickly calculate the spiral pitch that a legacy
drive gear will make if you know the number of teeth? This simple formula
works on all of the models using the Standard Duplex Gear.
Spiral Pitch = 180 / Number Of Teeth
Is this helpful? Not really but what if you know the pitch you need and
want a custom gear made? That's easy too.
Number Of Teeth = 180 / Spiral Pitch
You will find some gear combinations don't physically work on our machines.
I have found that gears between 20-120 teeth work pretty well with a few small
exceptions. Larger and finer pitches benefit greatly with reduction and
multiplication gear sets. Experience has taught me there are many different
combinations that achieve the same results.
I need to toss in a sales pitch here, if you need a custom gear built for
your Legacy, please contact me off list. I'll send you a custom gear chart
that shows the tooth count and the resulting pitches on the legacy so you don't
need to use any math at all!
