I dont believe our conditioner is analine specific. The leather hasnt been sitting for 5 years. We have been using this leather for 5 years and have never run into this issue before. hard to pinpoint the climate as texas likes to change its weather daily

We condition the leather once the product is complete. we have tired leather softener before turning it but to no avail.

Any advice would be greatly appreciated. Some of my products are 3 seperate pieces of leather sewn with welting together with one closed end. They are sewn inside out and i have to turn them right side out for the finish side of the product to be on the outside. I have run into an issue lately where one of my leathers has been cracking/tearing in the turning process. I have used this leather for years and this is a new problem i have run into. All my leathers are analine and this specific leather is a very soft finish to it but i just cant figure out why it is cracking/tearing now after 5 years of use. To turn the pieces i insert a rod into the open end of it and brace the tip against a second rod and roll the leather down to get it to turn right side out.

The thickest part that will be sewn is 7.5-8mm between leather and welting. I was curious do they make machines that have a wheel inside of the assembly instead of a feed dog? or do all machines have a feed dog and the presser foot is replaced with Roller foot. The thread itself will always be 135.

All, I am looking for a specific style of sewing machine but have had no luck finding it. I am looking for Cylinder Arm Machines with side mount bobbin that have a Roller Wheel set up instead of a walking foot. For context i am sewing 511/2 oz-6 oz leather with 135 thread. Can anyone point me in the direction of where i might find these machines. we are looking to switch over to this style from flatbed sewing machines. Any help would be greatly appreciated. Thanks, Rick

We have recently run into an issue with our products. As you can see in the pictures the stitches are "pulling" showing all of the stitch holes and thread. The product is constructed inside out and then turned by hand to show the finished leather. My issue is for many many decades we did not see this issue. Any advice on how to remedy this would be much appreciated. I am not sure if it is an issue with our leather, machines, or if it is causes by the person using the sewing machine. Thanks, Rick

I have used a few different places to order new parts for our machines. The main outlet is Universal Sewing Supply. My issue with them is we almost always get the wrong parts first then have to send back and wait for them to send the correct ones. We have been experiencing tension issues and loose stitches that loop away from the material. I am trying to find a reliable source for machine parts. We run Juki 1508 an Consew 255RB-2. Are there different levels for machine parts? For example the tension spring on your bobbin and on your thread tension knob. Are there heavier duty versions of them? The ones we get seem to not hold their strength very long and I have a feeling that is why we are seeing so many tension issues right now. Thanks, Rick

Does the needle size for leather vary between Juki and Consew? we have both machines so im trying to cover all bases.

I will look into different needles. We are currently having a problem with stiches and stitch holes pulling and showing on turned pieces. the only 2 things i can think of is either the needle or that it is an issue with out leather.

TO start let me say that myself and my lead mechanic have both given this machine the once over. Its a Juki LU-1508-N. I am not sure what is causing it to skip. we have retimed the hook and needle and by the shafts, new needles, we have replaced the hook and nothing seems to be working. Could a spool of thread that is wound too tight be the cause of it? The leather we sew is not very thick it vaires from 3 oz to 6 oz. Any tips would be greatly appreciated.
