Members paqman Posted November 23, 2023 Author Members Report Posted November 23, 2023 thanks all! I have officially rebuilt it last night, see below. The parts fit perfectly. Im not loving the plastic parts but they work, i may still find some brass stock and remake them in brass, it would also look quite nice. My main concern is the set screws stripping the plastic so i was careful when tightening them down. I had to omit the tension spring that usually stick out next to the big adjustment knob as it was also missing (Most likely broke off like the other parts). I put a washer and screw in there to keep that dial from falling of the post. Luckily, i had this black spring and installed it between the lift rod and the existing hole in the casting, this keeps the knee lift tension rod down at all times so pushing the knee lift increases the sew width and allows it to return to centre when you let go. The lever i made is used to adjust how you want to sew (Width), left to centre, side to side, right to centre. I have to drill the 2 outer holes once i figure out the limits of the needle but doubt i would use those settings. There are limit set screws at the bottom that limit the side to side movement so the needle wont swing out too far. The large knob needs to be loosened to allow the knee lift to adjust sew width on the fly, if you tighten it, it sets the width and wont allow the knee lift to move. There is a right hand screw keeping the knob from coming off when loosened all the way which is a nice touch. Quote

Yep i thought about that also! i have worked with alluminum before and it can easily be worked with woodworking tools... ill look into it. There is a metal supermarket near by, ill go and pick a few chunks and see what i can come up with... Quote
Members Quade Posted November 23, 2023 Members Report Posted November 23, 2023 Delrin comes in black too. I use black Delrin mostly. Quote
Members paqman Posted November 24, 2023 Author Members Report Posted November 24, 2023 ok so i struggled to adjust everything and it kept jamming, turns out, my lever kept slipping sooo.... i stopped at the metal supermarket and bought some aluminum and re-made the lever. Much better now! I got enough to remake the other bracket also but it is locked in place and is solid so i may keep it. Quote
