Good guess Bill I made a X4 multiplier that works very much like you are thinking.
Hay! the first owner used chain to run his set up, perhaps the second gear is for the chain? if linked to the gears, that would solve the long and short chain problem for different settings.and still give you a greater speed than what the Legacy could give you otherwise. (Just a guess?But its something to look into.) Back to work now. My break is almost over. have a great day.

Joe taking a closer look at your gears, it looks like the past owner tried to make his own directional gear set up. (the set of two gears that do not touch) I could be wrong, but the set that Legacy makes dose not look like that,(and I have never see anything like what you have in the picturem Made by Legacy) the gears should have been in-line not side by side. It looks to me that with the gears set up on your machine you should only be able to cut left handed spirals. I dont know if you want to spend the money yet. But Tim makes a quick change directional gear set that would allow you to replace your directional gear, It would make changing the direction of the pitch much easer and allow you a little more help to understand how everything works. The Order of the gears (names and purpose are) the 6 gears with the 1/4" square holes are called the drive gears, Next should be the directional gear, (its the set of one or two gears conected on a slide arm with in the gear set. ) Then the Duplex gear,(the large gear with the smaller center mounted on to it, and lastly the indexing gear, the Large (standard set) and on the .25 set (a lot smaller one) they have a rectangle hole in them, To connect onto the Legacy's center spindle (they also have holes in them for indexing.) Do you have any video (vhs or DVD) training tapes? If not, you can contact me off line, and I will send you some if you want. after seeing how the machine works a few times, it should be more simple for you to understand how the machine functions,and why. you will find for turning a straight spindle round, you can do as you did, with two handles,(controlling speed of movement of both the drive of the carriage as well and the spindle.) Or you can use your .25 gear set. and use only one handle to drive the gears. You will find the .25 gear set works but you will not get the greatest finish on a spindle with it. (I believe that is why the original owner made the chain drive gears, to get a better smoother finish cut on his spindles. I have to go to work now. Keep up the good work, Keep on watching the videos that Legacy has to offer, and then PLAY with you machine as much as you can, (I believe that is the best way to learn,) I will talk to you latter. Have a good day.

I have looked through back postings and found the sketch below which puts me on the right track, but i have a few more questions and have taken a few photos to try and get this "pitch" and travel in my mind. Someone asked if I had the 7 drive gears with square holes that are stock. I have 6 and read somewhere that 6 may have shipped with my older unit. Now for what I am calling the "idlers" that mesh the changeable drive gears to the 180 gear on both the standard and what "I Think" is the .25 gearset. I have three "frames" that are interchangeable that mount the idlers to the arm. One has two 60 tooth gears that are parallel but not linked. I cant see why you would need two unless one wants to space the idler in or out sometime. The other 3 are disassembled and seem to have been place in a homemade "sandwich" where the two 30 tooth gears mesh with a 60 tooth gear but not each other. I think the two 30 tooth gears will mesh together if I assemble them back in the stamped "three hole" pieces lying next to the homemade unit. I guess this would just be a way to reverse the rotation of the spindle to carriage drive. The small 16 tooth gear that was found loosely in the bolt is brass colored and was probably made to mesh to the 60 and replace one of the other 6 drive gears. Would someone please look to verify this and the gearset that I think is a .25? I am attaching the photos below and please ask if I can provide more detail.

I have no documentation whatsoever and the mill has had a home built drive to long screw axis added. I dont know the model but it appears the capacity is just short of 96" measured from headstock.
