Flywheel for Sailrite and other machines
Description
Updated design for 9.8mm XL Timing belt and sailrite (or copies thereof) machines. May also fit with normal machines of make is similar. Drive shaft is 20.3mm in diameter, OD of the wheel is 110mm. With an 8500 rpm motor, that makes 7 stitches per second as a pose to 12 stitches on the original 64mm diameter wheel. This wheel allows M5 brass inserts to be installed if you want to add additional weights sich as a concrete block or steel plate to it. The included "Mass" part can be filled with concrete or epoxy and metal shavings to add some rotational inertia to the flywheel The assembly uses two parts to save on supports. Only small supports on the inside of the engagement teeth on the flywheel should be added. Parts fit together perfectly and engage with the original slotted clutch on the shaft of the machine. This means there is no more possibility to disengage the wheel from the shaft, so lift your foot when winding your bobbins. Although this addon is designed to fail before the metal parts on your machine, you should still make sure that your machine is in great working order. Especially the needle and hook assembly should be checked regularly and sewing should be stopped once you hear any weird noise. Consider wearing safety glasses when working with thick fabric. The needle can easily break and pierce your eye(s).
