Bobbin winders are one of those accessories that really are more necessities. You can wind a bobbin by hand, but your arm will tire before you are even close to done. Also, the tension of the wound yarn will be all off which makes it difficult to use when you actually get to start weaving. There are a few other ideas out there (like using a pencil in a hand drill), but I thought it would be best just to get a “real” one to get the job done right.
Again, new ones seemed out of my price range and used ones weren’t much better. So, I started thinking: I really just needed a tapered rod that would spin with a bobbin jammed on it. Which made me think of treadle sewing machines which made me think about my Grandmother’s side table made from the treadle part of an old White sewing machine. The top had seen its better days and wasn’t even in good enough shape to refurbish as a side table, but the treadle was actually in great shape having been powder coated when the table was created. It was taking up room in my laundry room because I didn’t have the heart to do anything with it. Now, I could see a new purpose for it: a treadle powered bobbin winder.
My biggest problem was not knowing the proper terminology for the parts I would need. I knew they existed and what they looked like and even what types of things used them, but had no idea what they were called. It took about a week for me to figure out all of the different parts and the names all the while having to modify the design I had in my head because the parts were either too expensive or just not going to do what I wanted them to do. I settled on ordering a timing gear for a RepRap 3D printer, a couple pillow blocks in a matching diameter (the things that allow the rod to be stationary and yet spin), and a replacement belt for a treadle sewing machine. The only thing I couldn’t find was the tapered shaft which as you may have guessed, is kind of a big deal.
So, thinking I know what’s what, I ordered a chrome plated aluminum rod. When it came in, I found a machine shop in town and went in to see if they could mill it down for me. That’s when the enormity of what I was asking hit me. The guy was nice enough while I explained what I was trying to do. At first, he had the “just hear the crazy lady out” approach until he finally realized what I was trying to do and then he got intrigued. Sadly, he informed me that not all machine shops are made equally. WHO KNEW? There is apparently a huge difference between machine shops made for automotive needs and machine shops that are geared toward manufacturing. Once I thought about it, it totally makes sense from a crafting point of view. Just because you have a sewing machine and can make a quilt doesn’t necessarily make you equipped to whip up a ball gown. It turns out, the only shops in town were automotive machine shops and I needed a manufacturing machine shop which generally only works in bulk and I only needed the one.
Feeling frustrated, I tried to change up my design, but the tapered shaft is the main thing. You just can’t do it without that piece. As a last ditch effort, I emailed an acquaintance who actually teaches machining. I knew he most likely only taught automotive machining because that is clearly where the demand is around here, but I was hoping he could point me in the right direction. That’s when fortune shone down upon me. He kinda understood where I was coming from and like the first guy, was intrigued by my crazy idea. He asked to meet to see what I had and to see what he might be able to do about it. I was SUPER excited because I had almost given up hope.
And then another problem, my hero thought he could create the taper on a rod, however, apparently chrome plated aluminum is not a machinist’s dream. Luckily, he told me the steel I would need was readily available at Home Depot. This meant I had to wait until I could meet with him again in a week or so, but there was dazzling light at the end of the tunnel.
After a trip to HD and a couple more weeks, my hero brought me a tapered rod that fit perfectly with all of my parts and held the bobbin like a dream. I was beyond thrilled! Now, I just had to assemble it and see if my idea worked at all. (And then life got in the way for about 2 months – UGH!!).
Everything went together pretty quickly once I was able to get back to my grand scheme. I found some old wood to elevate the pillow blocks to allow the larger diameter gear to move without touching the table. I screwed the pillow blocks and wood blocks in place and put the rod through the pillow blocks with the gear positioned in the center. I then used a Forstner bit (1″ maybe?) to cut two holes in the table top. That hurt my soul a bit, but I consoled myself with the thought that at least the table was getting used now instead of collecting dust and laundry. I took the treadle belt and threaded around the flywheel, through the two holes in the tabletop, then over the top of the gear. I marked the length to cut and noticed that the belt rubbed against the inside edges of the holes. So, I took the belt back off, cut it to size, and used a round wood file to enlarge and smooth out the inside edge of the holes.
Once I had ensured the belt would not rub on anything, I completely attached the belt. It worked perfectly! I now have a foot powered treadle bobbin winder. Now, I can completely load a bobbin in just a few minutes with even tension. I probably didn’t save any money in the long run, but it was a great adventure and I now have the coolest yarn prep area ever.
