Members northquabbin Posted October 15, 2012 Members Report Posted October 15, 2012 I bought a used Boss and the Primary tension wheel cups were reversed (facing each other). This made it impossible to get the right needle tension. Check to make sure that when you stitch, the Primary Tension Wheel turns. Rule of thumb for thread tension is: The bobbin thread tension is half the tension of the needle thread tension (Bob at Tippman told me this). Keep trying and one day it will all click just like on the island. Remember nothing good comes easy. Semper Fi, 1969-1972 Quote

Members billymac814 Posted October 15, 2012 Members Report Posted October 15, 2012 Also make sure you're not winding your bobbins too tight. This caused me a lot of problems, especially when using the thing chucked in a drill it pulled it too tight. I now use a hand drill and make sure I wind them very even. I think mine works better when using 207 bottom with 277 top. Make sure you are wrapping the top thread around a full loop around the primary tension wheel if you have an older manual it doesn't show it correctly, check the manual on their site for the current version. I also replaced my shuttle with the new version that has the lock screw for the bobbin tension, this helped keep the tension set better. Still occasionally the bottom thread will be to tight and not pull the lock through here and there and ill curse at it but otherwise that machine was a lifesaver for me when I got it.

On the subject of bobbin winding for the Boss... I had about half a dozen stitches in a long line of otherwise perfect stitches, that had the knot showing on the bottom side of the leather. I called Ben at Tippmann and he was pretty sure I had a problem with my bobbin where the bobbin thread must have gotten snagged somehow. I'll admit, I'm new to the Boss, and my bobbin was not wound evenly, so that could certainly have been the problem. I want to avoid that problem again, but I have a question for all those that have more experience at this than I do. Is it better to wind the bobbin in a zig-zag fashion like a spinning reel does, or simply wind it flat and as even as possible? Quote
Members billymac814 Posted October 20, 2012 Members Report Posted October 20, 2012 I would think just wind it as flat as possible, I would think you'd get a lot less thread on the bobbin if you did a zigzag thing but I don't know for sure. Here's how I wind my bobbins. My Tippman is set up beside my consew 206RB and I use the 207 thread that I have for it, this gets me a little more thread on the bottom and keeps me from I threading the Boss to use the thread on it, I also use the Consews thread stand and the tension disks for the bobbin winder to keep just enough tension on the line to prevent the bobbin from unwinding and using a hand powered drill wind it slow and as even as possible without stretching out the thread too much as I think that is what causes it to snag a bit. I think I've had better luck with the smaller bottom thread pulling the knot back in to the hole too but its hard to say for sure.

Members trekster Posted October 21, 2012 Members Report Posted October 21, 2012 I used an electric (variable speed) drill and got a bobbin wound nice and flat. So far it seems to be working okay, and has not given me any erratic tension changes. Though I also upped the bobbin tension slightly, so it would be less susceptible to minor tension changes within the bobbin. I read somewhere that Tippmann states the bobbin tension should be about half that of the top thread tension. I don't have a tension gauge, but it seems like my present settings, that work rather well, have a bobbin tension that is a little less than half of the thread tension. But that's just a guess. Has anyone actually measured their individual tensions, to verify their bobbin tension is about half that of the top thread tension? Quote
