HELP! Skiver presser foot lifter keeps springing up!
LOM posted a topic in Leather MachineryHelp!! The presser foot lifter on my skiver will not stay down. It feels like the spring is shooting it back up whenever I try to skive. I have taken apart my consew dcs-s4 skiver 3 times to try to figure this out but cannot. The instruction manual is really only a parts catalog and doesn’t offer help. The spring inside looks fine. The rare occasion I get the handle to stay in the down position, it will skive for a moment the the handle shoots up and releases the presser foot so it doesn’t skive anything off. I bought it from a sewing shop that recently started carrying skivers for the pandemic demands so they aren’t very familiar with skivers and cannot offer much help. 66285906847__CB624500-FA42-4BA4-A712-97BE830DE189.MOV
Consew 226 Strange Resistance
Pintodeluxe posted a topic in Leather Sewing MachinesI'm having an issue with a Consew 226. When turning the handwheel there are two sticking points in the rotation. I wanted to determine weather it was friction in the upper shaft or lower shaft, so I slid the timing belt off and found the two sticking points were related to the lower shaft. So I reinstalled the timing belt, making sure to align the arrows under the machine (they were aligned before as well). I had to replace the hook anyway, so I went ahead and swapped that out. I chased the old hook out with a 3/8" dowel to prevent the gear from moving. Machine now sews well, but still has two points where there's more friction somewhere in the lower shaft. - Adjusted for symmetrical foot lift - Adjusted feed dog fore/aft position -Adjusted feed dog height - Made sure rocker bar spacing was 8.5mm @ zero stitch length All of these settings were very close to correct, and didn't seem to improve the friction issue I was having. I can remove the drive belt, thread, needle, and throat plates and feet and still have the two sticking points. Decreasing the foot pressure springs to zero makes a very subtle improvement. I have obviously oiled each point tenaciously, but still have two "sticking points" that occur when the take up lever is approaching top position, and approaching bottom position. Any thoughts?

Stitching Troubleshooting Cobra Class 4
bland posted a topic in Leather Sewing MachinesI recently (one month ago) got a Cobra Class 4 machine and I haven't been able to get it adjusted correctly yet. Is there a troubleshooting guide out there that shows pictures that say if your machine is doing this then try this? I did 3 passes the first two left to right and the 3rd right to left. I changed the needle between the first and second pass. Thread size 277 needle size 25 (passes 2 and 3 with S point)on a single layer of 12oz saddle skirting. The back side looks pretty good but the front looks awful.
troubleshooting Sewing machine trouble
Akmike45 posted a topic in How Do I Do That?Hi all! I am new to everything sewing... so you can bet that I have watched every tutorial out there that I can find. However, I cannot figure out why my machine sews 2 full stitches before my skipping many, many stitches. I have a Rex607z (shh! I am poor). I have been trying to learn for its equivalent machines like barraccuda 200z amd sailrite LSW. I have rethreaded, changed the needle (135x15 tri and upholstery thread...should be #69 but it does not say clearly), re-done bobbin, changed needle bar height, checked for burrs and bent things, and re-oiled everything. The kicker, the sewing machine will sew through jersey knit fabric (1 layer) with no skipped stitches. When I sew deer hide with a straightline, the ol' Rex makes two stitches then skips everything after. If it is in zigazag, it will only pick up the bobbin thread in a straight line..not in zigzag. Anyways, if anyone has any auggestions at all about what is going on and how to fix it, please let me know! Thank you all!
pyropixie posted a topic in Sewing LeatherHi All, I am new to the forum so if this is in the wrong place - please feel free to move my topic or even shut it down. I work at a store and we have a Singer 29K06 machine and we have always used it to sew patches onto jacket, no leather repair. All of our tailors are only familiar with how to run the machine but not troubleshoot. We had a tech out because the machine started skipping stiches but he was not familiar with parts for the machine because its so old. He mentioned that it had something to do with the timing. Does this issue sound familiar to anyone? Or does anyone have any resources that I could take a gander at to try and troublehsoot myself? Thank you for your help! Erin
A Big Goofy Stitch When Material Thickness Changes?
Miett posted a topic in Leather Sewing MachinesI have a Chandler 406RB that mostly works great, but I'm having some trouble with thickness changes while sewing. I make wallets, and when I'm sewing from the thinner section along the top to slightly thicker to down the edge where the pocket assembly starts, often I get this long loose stitch on the bottom where the thickness changes. Sometimes it's literally a loop a half inch or more long. Everything else looks good though, tension-wise, so I'm not sure what to do about it. Any suggestions for keeping this from happening?
Hi all, I'm new to this forum and just got a Cobra 4. What a machine. I picked it up from the shop last week and have been using it a few days. I actually initially went on this forum to fix a previous problem so thank you very much for the help already Anyways here's the problem and some questions: https://www.youtube....player_embedded I began having the thread jam yesterday while working on a messenger. I would get maybe 10 stitches into the thing and the thread would begin to twist a bit and kink and then a couple stitches later it would skip a stitch. I'd stop and fix it and then go on. The third time though it really jammed and I had to remove the shuttle hook and bobbin. I took out the jammed thread and put it all back together and now the problem is that the top thread won't hook the bobbin thread to take it up and out. I took a video of the thing and will post a link. After maybe 20 tries it finally hooked it but when I began stitching, the top thread wouldnt hook the bobbin thread and it only punched holes. So if you guys could help me out with this problem of it not picking up the bobbin thread and whatever is causing the thing to not stitch properly (the same problem I assume) I would greatly appreciate it. Couldnt get a word back from the Leather Machine today and ive got some projects I'd really love to be working on right now. Thanks so much.
Help With Dyeing
RNicholas posted a topic in How Do I Do That?Hi all! Second post here. I recently ordered a 6-7oz tooling shoulder from Tandy Leather Factory. The quality is fine, not amazing, but fine for what I'm doing with it. However, I wanted to see how some black dye would look on it so I cut some scrap off of it and tried to dye it (Gloves, wool dauber) and I found that the dye mostly just pooled on the surface of the grain and barely absorbed in. I could get it fairly well in after MANY coats, but I'm wondering why this is happening? It DOES look quite smooth, but is that it? I tried it out with an old round I had and the scrap side by side and the round absorbed the dye straight away but the newer shoulder just had dye sitting on top... Any advice? Will I need to sand it down or something? Concerned, R.
