Seiko STW-8B Seam length and presser foot height -

[Zonker62]

Hello all, 

I recently purchased this Seiko STW-8B, because of the triple feed, or walking foot, that I need in certain cases (sewing crystal windows on sprayhoods for example).

I didn't find any interesting manual like I usually do for Durkopp, Adler, Singer...Seen the ione for the Consew 226RB but no particular procedure for these items.

And my maximum stich length at the moment must be something like 2.5-3mm...And I thought it would be nuch more than that.

And also the presser foot height, it was set in such manner that the foot wasn't pressing the material (was probably set for some 1/4 inch thickness) and after lowering the bar I barely get 9-10mm (lower than 1/2').
Could anyone help me mainly to set correctly this machine, stitch length and maybe a word or 2 on pressr foot height?

Thanks in advance, 

Cheers!

Perhaps you could post a video of the walking foot in action so we can diagnose

The Seiko STW-8B basically is a later / more modern clone of the Singer 111G156 with some differences but it basically is a very similar machine.

How long is your maximum reverse stitch length? Usually when the reverse stitch is longer the forward is shorter (and vice versa). With other words, usually F & R are equal at approx 5mm at this type of machine (Singer 111 and later clones) so when the F is 3.5mm then usually the R is longer and I guess it is 6.5mm.

Hi!

Thanks for the replies.

F&R are exactly the same and there's a beautiful reverse giong in its path.

I will post a video so you can see and diagnose but I was looking for something written, 'cause both Seiko/Consew manuals are scarce on the tuning...

The Juki 562 / 563 manual is probably the closest for your SEIKO STW8. See attachment.

Can you post pictures from the underside of your machine maybe the stitch length has been limited for what ever reason.
