Help! Wanted Techsew Stitching Nirvana, Got The Blahs Instead

[YinTx]

I think I could use some help here. Recently removed the round point needles that came in the Techsew 4100 machine I purchased, and installed Organ 794 LR Size 230/26 with white 277 thread. First round was a complete disaster, finally managed to get the results shown in the photos. Not certain it is what it should be though, and I can't say that I'm happy with it. Any suggestions on what I should be doing to get this to be a better stitch? Also looks like it is blowing out the back, not a clean exit. One row is just with the needle, the second row has the thread.

Yin? who did you let talk you into 100.00 worth of needles and to change what the tecksew had in it already. Did it sew with that needle?

[YinTx]

No, it didn't sew well with the round point needle either. From everything I can find, round points aren't necessarily intended for leather anyhow. I am hoping this is operator error here.

[DoubleC]

It could be yin, machines have a steep learning curve. I think the 26 is too big though, I really do. I use 24s with my 277 and it seems to work well. I get mine a pkg a time from cobra steve and he tells me what I need.

I´d say too thin thread or too thick needle.

I´d try a 180 to 200 (metric) needles for 277 thread (180 might be a bit tight but I´d at least try it) and would reduce the foot pressure on the center foot as it leaves feed dog marks on the backside. Leather seems not to be very thick so a round point needle could probably work fine but depends on the result you expect. Different points produce different seams.

I think I have seen a chart from GROZ BECKERT showing the different seams that the different needle tip will produce but can´t find it atm.

LinTx;

#26 needles are meant for #346 thread, top and bottom. Try some Schmetz #25/200 S point needles. They produce an inline stitch, with minimal bottom puckering, depending on the pressure on the presser foot.

YinTX. We sell both Schmetz and Organ in both Leather Point and Round Point.

How thick is the leather you're sewing? you should probably go down in needle size and thread size.

Check to make sure your needle is aligned at the right angle. Those needles should cut a 45 degree angle cut and they look rather flat across. And yes they are too large for the thread and leather as others have posted. Gump.
