Boss Tension Adjust Ment Question.

[mlapaglia]

I just did an 8/9 oz single layer belt. 55 inches long. Im a big boy. 277 thread top and bottom. Full bobbin on bottom. 794-200 needle. About every 5-6 inches I got 1 stitch where the bobbin thread was pulled up to the top or the top thread was not pulled down. They look the same.

Any idea what caused that?

As an aside, a single line of stitching in white 1/8" all the way around on a balck belt really made a difference on how nice it looked. It made it sort of pop.

I am really learning to love this machine.

I would check to make sure the thread is coming off the spool/cone smoothly. Sounds like it is binding slightly someplace between the spool and the needle every few stiches.

I kind of thought that too but it goes 5-6 inches so thats 30-36 stitches. thats a lot more than just a few. If I pull the thread free at the first post at Guide post one. then it mess up the tension on all the stitches. It does not seem to be catching at the spool. At least not that I can see.

I've been getting a lot of snags where the thread (straight from the spool) goes through the metal loop on the thread stand. It snags when the thread coils up and flips over the top of the metal guide. To minimize the problem, I took some pipe cleaner and wrapped it around the metal to create an additional guide an inch or two before the metal guide. This helped, but does not eliminate it. I just make sure and take a peak at the thread stand every 20ish stitches (I count in my head). Maybe one of these days I'll create a custom metal guide rod that's considerably taller so the weight of the thread itself will help keep the thread from looping over the top of the stand. Or, maybe I'll add a secondary guide at the same height as the current guide. I even though about cutting up one of my kid's plastic loopy straws and placing a "U" curved section in the loop and securing it with modeling clay. I think that alone would solve my problem with the thread looping over the top.

I was having the same problem. I took a 2 inch long piece of 8/9 oz and wedged it in the opening of the thread stand. this stops the thread from flipping out of the thread stand completely and also from flipping over the thread stand.

I'm starting to dwell on the idea of somehow mounting a funnel over a spool of thread and feeding the thread through it to the loop or hole in the stand.

Now that sounds like an interesting idea. Keep us posted please.

How about running the thread through a small piece of foam just before the guide above the cone/ spool. This would add just an ounce of tension and keep the thread from looping.

I have also heard of putting a knitted tube of some sort over the spool. One lady uses a piece from the leg of worn out pantyhose.

I called Ben at Tippmann. My problem is either the thread catching at the top and popping free or a bobbin that is not wound with the same tension all the way through. I know when I did this bobbin the thread snagged a few times as it was winding causing the drill to pull toward the thread. I am willing to bet that this caused a bobbin that was not tensioned evenly. I have a low speed screwdriver that I ordered a chuck for. I am going to mount that on the bench so I have a place to do it properly.

Thanks for all the help.

Michael.

A little time has passed but I wanted to post a follow up to the thread snagging issue I was having. Thanks to Wizcrafts, I placed a plastic funnel over the thread cone and this 100% fixed the snagging issue I was having. Before adding the cone, I took a plastic curvy straw from my kid's collection, cut a section from it and placed it in the thread guide. This might have helped a little, but I still got the thread snags because the thread was still flipping up and looping over the metal stand.

I can't say the funnel by itself cured the problem due to the design flaw in the metal stand's thread guide loop, where it can easily snag the thread if it slips into the opening (which mine has done on rare occasion). You might find it worthwhile to modify your metal loop on the stand to eliminate the possibility of snagging. You could smear a little JB Weld or epoxy in there (try not to make a mess), or even look for an appropriate size rubber grommet - though the rubber grommet could add additional friction, resulting in inconsistent top tension. Personally, I'm happy with the plastic straw method, though I may see if there is a rubber grommet that fits the metal stand and has a small enough hole to securely hold the plastic straw. Otherwise, you could hold the straw in place by filling the opening with a little modeling clay.

Thanks,

It's always nice to here the updates. I got that chuck for my power screwdriver and it works great for winding the bobbin at an even tension. I finally got to the point that I can adjust the machine when changing thread sizes in just a few secs.

I really love this machine.

that exact thing happened to me and i didn't notice until it really caught, the thread coming off the spool going up through the metal guide on your thread stand thing wasn't helping the cause either, i had to bend it to keep this from happening. once i noticed it i payed attention to it and it was doing it more and less depending on what part of the spool of thread i was at, more of a problem at the bottom obviously. someone told me to use a little spray of silicon on my roll of thread and that would keep it smooth throughout the whole machine.

hope this helped

Now I know we're not in Kansas anymore! Is that the Coneman?
