When I got back from SOAR a few days ago, the first thing I decided to do the next morning is put together my big Alden Amos spinning wheel. I took her apart three years ago to bring her to a class, and I haven't been able to reassemble her since. (The wheel is fine. It was just me who was a bit broken.)
Well, it was time to bring her back to life. And here she is, in all her cherry glory.
Here's a close up of the bobbin/flyer area. Alden machines every piece of metal himself for an incredibly precise fit between shafts and bearings. He also hand-forged the wide metal band that holds the mother of all onto the wheel.
This wheel was custom-built for me. And when I say "custom" it isn't that I just placed an order for it and waited for it to arrive. Alden has a very interactive building process when he makes you a wheel. He sends you his infamous questionaire, in which you measure the length of your leg, the speed of your steps while walking, the climate where you live, etc. etc. The questions aren't random. Neither is his request to send him samples of your typical yarn. It isn't to critique your spinning. He needs to see how much twist you normally add to your yarn. Alden asks about your walking speed, because we generally treadle at the same pace we walk. So he puts the two numbers together, and it gives him an idea of how much twist should happen ideally with each pump of the treadle. He asks for your leg length, because he needs to know how high/low to put the treadles and flyers. And he asks about your climate because wheels that live by the ocean, for example, need to include accomodations for fluctuations in humidity.
Okay, so I filled it all out and asked for a wheel in cherry wood. With fancy spokes. And oh... the flyer needs to be on the right side, not the left. I spin at a wheel the same way I spin with a handspindle: fiber supply in left hand, right hand controlling the twist. It is far more comfortable for me to have the twist entering the yarn on the right side. That way, I can draft across my body, just as I'd do with a spindle, in a very relaxed position, no strain from twisting. Alden chewed on the right-handed flyer thing for a couple of days, but he eventually said yes and didn't give me TOO much grief about it.
Finally -- and this is the kicker -- I wanted the capabilities of different speeds to spin different yarns. In addition to the standard speed, I wanted a high-speed lace set-up, as well as a low-twist heavy duty thing to spin thick singles and rug yarns. I thought it would be a matter of getting a few different whorls.
Oh boy, I was wrong.
This is why my wheel is so singularly wonderful. You see, Alden doesn't just slap a different size whorl on a flyer and say, "There, it spins faster. Go to town." You see... simply spinning a flyer around faster doesn't help much. Why? Because there's the whole issue of take-up.
When we spin, especially when we spin fine yarns, there has to be a very precise amount of tension on the drafting triangle. We need to draw out the fiber without feeling the wheel grab it from us. At the same time, when we release the newly spun yarn, we want it to wind on the bobbin INSTANTLY, with a really robust take-up.
For this to happen, there has to be a very precise relationship between the size of the whorl, the size of the bobbin, the weight of the flyer, and the weight of the bobbin. This relationship also has to take into account the increasing weight of the bobbin as it fills with yarn. Both the empty bobbin and the full bobbin have to stay within the acceptable limits. If any of those go out of balance, the take-up goes out of whack.The wheel will either stop pulling the yarn onto the bobbin, or it will grab too hard. This, in turn, can cause issues with difficult treadling or too much wear and tear on your wheel's moving parts.
So when I asked for different speeds, Alden said the only way to do it was to provide a completely different bobbin/flyer assembly. And... I got three.

Each assembly is completely separate. From the mother of all to the bobbins to the size of the orifices, they are crafted completely differently.

Anyway, at the end of all this, I have the spinning wheel of my dreams. It spins quietly, silently, and fast like the wind. No rattling or squeaking. The take-up is perfect. Treadling is effortless. I can spin as fine and fast as I want, with any drafting method I want. And when it comes time to wind onto the bobbin... zing! It's there. I barely need to adjust the tension as the bobbin fills. I can sit lazy in my rocking chair and spin comfortably for hours.
It's a delight. I'd forgotten how good it felt to spin on this wheel. Now, I can barely pull myself away from it.
Oh, and it always amuses me to bring her along with me to some spinning event. She knocks down into little pieces. (All the legs and arms and turny bits easily come apart.) So in one hand I carry the drive wheel, in the other I carry a bag with the wooden stuff. It doesn't take very long to set up again. And people always gape when a wheel emerges from the pile of sticks...
