Members katit Posted January 30, 2019 Author Members Report Posted January 30, 2019 That,s not a problem.. timing I can deal with. My problem is a belt itself. I need to know if it’s OK to be loose like this. To be about 1/8 narrow comparing to old one I guess not... old belt is not original either, but it’s pretty tight on gears Quote
Members katit Posted January 30, 2019 Author Members Report Posted January 30, 2019 Btw, I read whole archive, all topics from Eric and Uwe. Pretty much ready to go. But looks like I got a bad part. All ebay sellers list belts and say there is 3/8 variance in length. Those machines don’t have tensioners, I will take short one please:) Quote
Members katit Posted January 31, 2019 Author Members Report Posted January 31, 2019 (edited) Well. I installed old belt. It's frayed on one side a little, I carefully cut those loose strands, washed with soap. Its pliable, no cracks/etc. Decided to let it be. When I timed top-bottom I realized that it really can be 1 tooth here or there. Hard to tell. I tried to go by "eccentric" feel on top because there is some movement in TOP here or there. I also tried to go with all slack removed as machine being turned by the top pulley. With what I described it's about 1/32 off on bottom mark. Oiled everything and everywhere. Spin and oiled. And again. It was all cleaned with kerosene and then blown with air. It's literally dust free and now all soaked in oil. Now dealing with hook timing. Everything. And I mean everything need to be adjusted. Reverse, foots, stitch indicator, etc. Will be fun Edited January 31, 2019 by katit Quote
Members katit Posted February 1, 2019 Author Members Report Posted February 1, 2019 @Uwe, @gottaknow Eric/Uwe, calling for help!! Today I started to adjust machine. First step - hook timing - went perfect. Little fiddling, got it just the way in Uwe 225 video shows. One thing I wanted is little better mesh between gears (back gear more to the right). Another problem I noticed comparing to what it was - needle bar was about 1/8 inch too low. Installed new feed dog and plate. PROBLEM #1: Feed dog rubs on a plate, picture shows it (left side). It also was hitting plate on a bottom (too high on setup). Got it all way down - see how bolt is. So it moves more or less, but I fiddled with a feed dog while screwing in - tried to keep it on right and centered - this is best I got it. Still not centered in a plate. However, needle is centered. So it's something with plate? Just to be clear - old parts worn out but they were same way, crooked and not centered. Also, feed dog is not horizontal, it tilts a little. So OK, this was somewhat moving. PROBLEM #2: Followed Uwe's video on setting up walking foot. Equalizing them. When I got small foot down, needle touches material. Loosened camshaft, both feet dropped as prescribed. Tightened. And no go. Now front cam hits case casting (arrow in picture) How do I solve those 2? Even though dog moves - if I increase stitch len to anything other than smallest - it starts to rub badly. Quote
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 shoepatcher Posted February 5, 2019 Members Report Posted February 5, 2019 Very very nice. glenn 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
