Wyowally Report post Posted March 16, 2023 I've got one that sews air pretty good. This one has the single roller foot. Problems when threaded. I have searched all of our forums. Question and comments: It is timed pretty well, using proper needles and 138 bonded. Without the specific manual, how can timing be adjusted? I have needle eye to hook point at about 1/16" There is a lot of wear or clearance on/under the main needlebar screw. The big-headed one with a curved slot. It is stuck. I'm assuming this is the left-handed one like on many machines, and it is stuck with age. Is there any hope for it? I'm not used to seeing that much movement, linkage to shaft. I have the hook to needle clearance looking good, but the right side of the needle is right up tight to the hole in the needle plate. Looks wrong to me. Is there a left-right needle adjustment I don't know about? What is the adjustment for presser foot travel with the roller? How much clearance should I have with the roller raised? Is there an adjuster's manual or set of instructions that I have not found? Is there an adjustment for feed dog travel? This is making holes about 3mm apart on max. When threaded up and sewing 5oz. veg tan, turning the wheel by hand, there is always extra resistance right when the needle eye is ready to pull back up into the leather. I'm blaming the clearance right side to the needle plate. There is no resistance without thread and just poking holes. There is a lot of movement on the shaft and linkage for the needle bar clamp. Is the linkage supposed to just ride on the clamp screw shaft and move laterally if it needs to? It does make stitches for a couple inches, but then upper thread gets tangled, twisted or something underneath. Perhaps that's enough questions for now! I know that's a lot, hoping those that know will chime in. I'll be patient..........thanks. Quote Share this post Link to post Share on other sites

Wyowally Report post Posted March 16, 2023 (edited) Thanks Constabulary. I know you've resurrected this model yourself. I should have mentioned I have this manual and the illustrated parts book. I was hoping my words would be descriptive enough, but can do pictures today. I have worked on many older machines, industrial and others. Hoping Glenn will see this. He's helped me out with other problems. Edited March 16, 2023 by Wyowally add text Quote Share this post Link to post Share on other sites

Carefully resetting needle depth and orientation, check spring travel and tension, upper tension, etc. Smoothed the edges of the hole in the needle plate. Reset the presser foot travel and pressure. One of those must have worked! I use the shotgun approach..... :). Quote Share this post Link to post Share on other sites
