oldfarmboy Report post Posted May 21, 2021 In need of a tension screw for the bobbin case on this machine. It sews as is but it needs to be replaced. Suggestions appreciated. Also discovered the two original locking set screws on the hook driving shaft pulley are missing. Someone replaced with an standard 1/4 x 20 TPI set screw which is NOT correct thread. My measurements are 1/4 x 24 TPI. Project for today is machining screws. That's doable but not attempting a tension screw. These old eyes can barely see those tiny screws. Oh also the felt oiling pad is missing on the bobbin case. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted May 21, 2021 You can find these screws on eBay or from any industrial sewing machine dealer in the World. The hook used in your machine is one of the most common in existence. Why not buy an entire new hook, and a new driving gear? Techsew is in Montreal and can help you with parts.

oldfarmboy Report post Posted May 21, 2021 Well I'm wrong the set screws are indeed 1/4 x 20 TPI. I finally took gear off to get a good look at the threads. Quote Share this post Link to post Share on other sites
