Sewing Between 1 And 2 Layers Of 5 Oz - Cowboy 3200 Best Way?

[BDAZ]

Many of my designs require stitched two pieces of 5-6oz black drum dyed together and then jumping to a single layer for a decorative stitch then back to the two layers. I have never been able to get the bobbin thread on the single layer to pull down to the middle of the leather no matter how tight I make the bobbin nor how loose I make the thread tension. I occasionally will use a marker to touch up the thread so it looks ok or even use black in the bobbin when only the top is visible.

The image shows the transition between two and one layer with the tension readjusted to minimum.

Is 5-6 oz. too thin for the 3200? I am using natural poly 207 top and bottom with a 24 needle.

Any suggestions?

Thanks!

Do a test with a number 23 and a 25 needle and see if either makes a difference. Chart I use recommends a 25 for 207 thread, which would make it easier to pull the thread up, which would mean reducing the top tension even further. 23 would make it harder to pull the thread up so would require more top tension. As to whether one or the other might work, only a test will prove it.

I have finished my first batch of product so I can do some testing tomorrow. At this point I'll try anything but there is a noticeable difference on the tension between the bobbin and needle when I loosen it for the single layer. Any looser and the springs will fly off..

Thanks!

Cya!

Set the tension for the 5 ounce piece and it should sew fine on the thicker part my machine does anyway.

I can't get it to sew the 5 oz. What you see is as good as it gets. Bob even sent me a lighter spring for the upper tension but it didn't make much difference. I initially thought this machine was not capable of sewing a single 5 oz layer.

Thanks!

I tried the 25 and it made no difference, also played around with the tension with just marginal improvement. The knots are still visible from the top but they are below the surface.

Thanks!

I have this same problem with my machine on thin leather.

Bummer. My Cobra Class 4 doesn't have this problem so I cannot advise you. Sorry

Where you have to decrease the top tension to just about nothing, try increasing the bottom tension so you have more range to play with.

I quote from my initial posting:

"I have never been able to get the bobbin thread on the single layer to pull down to the middle of the leather no matter how tight I make the bobbin"

Thanks!
