Thread Fraying sewing Kodiak

[Dwolf01]

First, thank you ALL! I have started making, and even selling, small leather goods in large part because you all take time to help one another out! Grateful for all of you and you expertise! 
 

I have been trying to figure out what my thread is fraying…here is my situation:

using a consew p1206rb, size 19 needle, sz 92 cowboy brand thread (shout of to Bob in Toledo ), sewing two layers of 4-5 oz kodiak leather. 
 

So far I have…

-rethread top and bobbin several times, tried new bobbin, changed needles, took smooth sanding cloth to the bobbin hook, adjusted the tension(tried sewing at about ever tension)…still struggling. Need to fresh ideas! Do I need to use heavier thread? I like the look of the thinner thread. Advice welcomed! Thanks in advance!!!

A couple of photo's of how you have your machine is threaded from the thread spool to the needle may help in identifying your problem. I think the needle size you are using (#19) is probably the cause of your fraying where the needle isn't creating a hole big enough so the thread is getting ever so slightly caught and not making the correct size loop for the hook to properly catch. I would recommend moving up to a size 22. I am assuming you are using a 135 X 16 needle meant for leather not a 135 X 17 Multi-Purpose Needle.

I would suggest a size 20 needle

If you check your manual the needles you should be using are DP x 17 (135 x 17) for fabric. What you have are DP x 35S (134-35 S) which are not the correct needles for your machine.

Thank you!!! That would explain a lot!! I am sewing leather so should I still get the dp x17 (135x17)?

No, for leather get DP X 16 (135 x 16) in what ever size you need for your size of thread and get a few one size up for tough thick leather.

I have not used them myself but they are supposed to better then your regular needles. I do recommend you check out Wawak (www.wawak.com/Sewing/Needles/Industrial-Machine/) for your needles as they usually have really good prices.
