Members katit Posted February 4, 2019 Author Members Report Posted February 4, 2019 (edited) Reporting success!!! Got machine sewing today. At least I know nothing wrong with it and if small tweaks need to be done - I kind of know what to do. I really wish someone helped here with more advice.. Machine works! No more skipped stitches, runs solid and smooth at any speed I tried. 4-6 layers of upholstery leather - no problem! Feed dog: Original was 6.05mm wide. New one was 6.3mm wide. Took it to mill and made it 6mm. No rubbing, all great. Feet: Adjusted per Uwe's video on Consew 225, worked almost great. Except it is hitting casing as in picture of previous post. For now I adjusted it where it almost touches casing and it's almost like it should be. I wonder if I have to remove that piece of casting allowing for more movement? Stitch len/reverse: It was set to do about 11mm stitches and no reverse. There is no adjustment block like in Uwe's video, but I figured out what I should adjust and used 2 red bolts in picture. I turned blue bolts all way out almost to make stitches as long as possible. I guess previous owner didn't care about reverse and needed longest stitch possible?? Now it does ~6mm forward/reverse. Not exact forward/reverse, but fine-tuning will be using blue bolts and sacrifice some len. Another thing about stitch length is speed. It looks like if I run machine at full speed - stitch size increases a little. I wonder if it's related to not just perfect feet timing and the fact that feet right now is smooth feet on a bottom. Safety clutch: It was glued in, now it works. I tried sewing different tough materials - all great. Where I do have issue - it's when adjusting stitch size. When increasing stitch it's tight turning and causes clutch to pop. So I'm not sure if it's clutch or adjustment mechanism need to be dealt with. I did adjust stitch turning shaft with vise grips. I oiled it, soaked. Tried adjusting both ways and it loosened somewhat but still flips clutch when adjusting. I wonder if this is why previous owner got it glued. I see bunch of different bolts which supposedly can be used to loosed stitch mechanism, but hesitant to touch any of it for now unless I understand what to do.. Overall it works great, no binding of any kind. Everything very smooth. Front cover broken bolt fixed, all parts in place. Edited February 4, 2019 by katit Quote

Members katit Posted February 5, 2019 Author Members Report Posted February 5, 2019 Yesterday I loosened stitch adjustment just tiny bit. More oil. Now it moves. I can adjust stitch both ways without using other tools (aka vise grips). Still, need to turn slowly, otherwise safety will pop. For that matter I consider restoration complete. Will sew some parts make sure it performs correctly with real stuff Quote
