After getting my George in January, I asked a great number of questions about getting the tension just right.  A number of discussions addressed the deficiencies of the SideWinder bobbin winder.   Many warned me about the inconsistent thread quilting tension I could expect from using it.  For this reason, I went about ordering a bobbin winder along with my friend that had just gotten a Gammill Charm.  As she owns a business, we were going to get two bobbin winders at cost.  In the end, the winder order was held up.  During that time, I decide I could make the bobbin winders for each of us for no more than $40 each. 


Below I have provided a list all items needed, along with the costs of the supplies including sales tax, and the place I purchased them.  While the actual winder is long 12 inches, I but the wood to 15 inches to ensure it did not

            (item 039003495650)


Total                                                               $51.94



I did go a little above my cost projection, but I am satisfied with the results, as is my friend. 


While the actual bobbin winder is 12 inches long, I chose to cut the wood 15 inches long, so the bobbin winder would not hang over the side edges if it needed adjustment.  I also spray painted all the parts so they would match the actual bobbin winder, as the motors were different colors.  If you spray paint the motors, be sure to stuff paper towels down into the cooling vents, so no over spray gets into the internal parts.  Remove all the paper towels prior to assembly.  You do not want to burn up the motors.


Both of the motors I purchased came with hubs for sewing machine belts.  I took the hub with me to Ace Hardware, and purchase a rubber grommet that fit over the hub and would not spin.  You can put a rubber grommet directly on the motor shaft, but the bobbin winder will spin slightly slower.   The larger size hub, allows the maximum motor speed to be transferred to the bobbin winder. 


Online, the Lutron switch stated is was motor rated, the actual packing material stated it was not.  I figure that the switch will be energized so little while motoring the bobbin winder it will not damage the switch or the motor.  If you do not want a speed control, you could use a normal ON/OFF switch that would lower the total cost about 3 dollars.  I wanted to be able to wind invisible thread slowly, so I went with the dimmer switch.  You could also go with poplar wood to lower the cost of the wood.


Here are some photos of the two final bobbin winders.  They work great.  The only problem I notice is the rubber stopper leave black marks on the flywheel.  You need to add a drop of oil to the flywheel shaft ever now and again, to keep it lubricated. 


On a final note, I e-mailed Bob Purcell (Thread Doctor) at Superior Threads concerning how to best wind bobbins.  His reply is below.

“Professionally wound bobbins are wound quite hard in order to get as much thread as possible on the bobbins.  Stretching isn't an issue for cotton (very little stretch) and quality polyester (slight stretch).  Nylon or cheap polyester could be a problem.  I recommend winding at the fastest speed that allows a smooth wind with a moderately tight tension setting.  Too much tension will cause breakage while winding.”


I hope this helps you know how to make your own bobbin winder, and how to wind your threads as needed.
