Viking Platinum - Small Sitches Over Seams
What can be done about small stitches over seam intersections.

I acquired a Viking Platinum 750 last fall. The machine has been serviced. I like many of the features of the machine and the way it sews. There are also a lot of annoyances, but the big issue is that it makes small stitches over multiple intersecting seams. An example of such a seam is an eight triangle pinwheel. (There is not enough bulk to use a hump jumper--even if I were inclined to do so.) I garment sew as well, and a simple double turned hem will present the problem at seam intersections.

Owners of Platinum and other Vikings--do you have this same issue? What have you done, or can be done, about it.

Suggestions from owners of other machines are welcomed and would be appreciated also!

You may need to adjust your presser foot pressure. Your machine does have adjustable pressure and it sounds like yours is set to put too much pressure on the fabric. If you can find the setting, ease up on the foot pressure and see if that helps. I know what you are talking about and its annoying-- but on your machine, it will be an easy fix.

I tried your suggestion, and the stitches were better--not as small as before. But they are still noticeably smaller. I set the pressure to 2, 3 and then 4. On 2 it was very hard to keep the fabric feeding straight, on 3 somewhat the same, on 4 the stitches were the same size as on the other two settings, and the fabric movement control was good. Previously I had set the pressure high--around 8. When I did these samples the stitch length was set at 3.5. (Set at 4 the stitches were just too long.). I would say that over the seam the stitches decreased to about 2.75; whereas before they had decreased to about 2.0. So that is considerable improvement.

Is there anything else to try for further improvement? Anyone else have ideas? When sewing a hem on a garment the smaller stitches do not look professional at all.

Thanks so much!

I wonder if you might want to take it a dealer. Its possible the feed-dogs are set too high. This would be a quick and easy fix but not something you can do yourself. Do you have a dealer near that you trust? It wouldn't have to be a Viking dealer. These are GREAT machines and I feel the problem is probably minor but it just has to be related to the dogs or foot pressure. It has the power for it, that's for sure. I'm not sure what else you can try but the fact that easing up on the pressure did help...is a clue it is something w/ the feed.

The solution may be just the opposite. Sometimes you need to increase pressure to sew heavier fabrics. The effect is to "squeeze" the fabric layers together and thus make it easier to sew.

I have seen this on many machines over the years -it is just from the fabric having more trouble feeding through due to thickness, as others have indicated. It's also no big deal as far as I can see. Sewing over bulky seams is something my Viking does well, but I bet the stitches over the hump are sometimes smaller. Unless you are doing a decorative topstitch this shouldn't be an issue.

Would using a hump jumper help?

You could fold up a piece of paper about the same as some intersecting seams and sew though it with no thread at all and see what happens. You could see the needle holes pretty good that way, and if they do not get smaller and closer together the same way, in the same kind of places, then maybe something about even your fabric or thread is catching and retarding the fabric with real fabric and thread instead.

What that would be, I don't know, but maybe some dings and hits on the sides of hole in your needle plate that for some reason just catch thread only when going over a seam? Or anything scratched up and rough on the bottom of the pressure foot? Or maybe if you got some loose thread ends on a 8 piece intersecting quilt block area that might get stuck in the pressure foot?

I do get smaller stitches on all my machines going over taller places (right before too tall to even sew though a machine most times) if they are really tall enough to be under a pressure foot to make that happen, but sounds like 8 layers of quilting cotton is not all that very tall.

But if using a jig or a jean a ma jag actually seemed to make a good difference there, I actually would not just "refuse to use it either" out of just principal and be left with small squished up short stitches either.

Anything could be a jig, it does not have to be a real plastic Jean a ma jag, made just for that purpose at all and it does not have to even be as thick as either end of one of those if you did not want it to be. It could just be a a piece of folded or not cardboard, or maybe a cut piece of plastic quilting template, just anything actually.

Actually, now I think a eight triangle pinwheel, is not just 8 layers of fabric, is that not instead maybe more like 16 layers of fabric right in the center there, all in the same place, if they all intersected at the same place? 16 layers of quilting cotton, in a lumpy bumpy spot, I think is way tall enough to use a jig on any machine and also would be taller the less you pressed it, and steamed it down first or maybe pounded it down with something?

That's a great idea... sew paper without the thread to see what the needle is doing. Thanks.
