Damed me and my tinquering....
I think I am going to need the address for that fix-it message board.
but mean while here is what I did.
A couple of months ago I went and had my sewing machine fully tuned-up... after messing about with it for a couple of weeks. The nice , retiered, gentelman who fixed it told me never to play in it again.
I am rather proud of the fact that I held out for two months. :-)
After making my very first shirt, I noticed that the button holes weren't as regular as I would have expected ( the zig-zag on the left was longuer then the one on the right), So I gave the mather a some thought and decided that screw A ( just for futur reference ) needed just the tinniest little tweek. And it actualy worked perfectly. ( Hurray)
This was yesterday. then today, full of myself, I decided that I would measure the stitch lenght and adjust that too. ( I had read in my reference book that on machine such as mine with the stitch lenght 0-1-2-3-4 that meant 1 mm, 2mm, 3mm etc. ) So I got out my ruler and started fidling around with screw B.
Oops
Now I only played with the two screws ( on the inside of the machine obviously). And I guess if I played around with them I could probably get it back to where I had the machine yesterday ( near perfect). But that doesn't make much sence. I know enough about this type of thing to know that there is a sequence to adjusting, So I need to know that the hell said sequence is and what the bench marks are.
it this helps.
My machine is a 30 years old japanese badged machine sold in Canada under the name Omega Super 900.
It has a side loading bobin, no cames, 0 to 5 zigzag ( 0 being straight),
4step button hole ( 3 settings), extendable zigzag, hiden stitch, triple zz, 4 extendable(decorative) stitch, a triple ( or extendable) straight stitch, drop down feed dogs, and a reverse.The stitch selector is a nob, the stitch lenght is also a nob and the reverse button is stet in the midle of the stitch lenght.
Screw A is attached to the reverse arm inside the machine ( I know this because the screw and the arm drop when I press the revers button). Screw B is set in the stich lenght control ass ( I know this because the screw moves back and fort when I play with sticht lenght).
I am not sure what else to tell you beside that , when adjusting the button hole i noticed that screw A didn't affect the reverse zz ( left side of the button hole) but the forward zz ( right side of the button hole).
PLEASE HELP ME , I swear I will never fiddle around in my machine again (for the next couple of month).
