Thread Tension Adler 67

[IslandMoose]

Hello all

I am finally stitching with my new 50 year old Adler 67AE-72. I am working with the thread tensions and struggling. Despite increasing upper tension to what I think is pretty silly levels (hard to pull), the knots are still showing under the fabric. The bobbin tension is firm but can be pulled easily

I have enclosed two photos of a 6mm stitch in 4 layers of Sunbrella. The needle is likely too small (80) for the v92 I'm using, but this will only increase upper tension?

Thoughts? What's going on?

Interestingly, I couldn't get the bloody thing to work until I realised that on a 67AE you must thread the needle from right to left (the hook is on the left!)

Do you suppose the needle mismatch is the problem and the hole size is pulling the knot down?

I would use a #19 (120) or 20 (125) needle with #92 (T90) bonded thread. Little doubt that is your problem. The hole is too tight on the bottom. A larger needle pokes a wider hole, reducing the force needed to pull the knots up.

A package of Schmetz 19/120 needles should be arriving in the mail this week. Thanks for the help.

I find the world of thread and needles VERY confusing ...my thread is technically TEX110, which is some different unit of measure, but is effectively #92 (T90) thread. The Adler uses 135 series needles....so...

I am using series 135x5 or 135x7 19/120 needles for my TEX110 #92 (T90) thread...Im almost ready to give up before I get started!

Tex 110 is a little thicker than B92 (Tex 90). You might need a #20 (125) needle for that thread.
