myjtp Report post Posted October 19, 2018 Just got my Bonded nylon thread and needles from CowboyBob SUPER fast shipping and best price! #207 Top thread, #138 bobbin thread, 135x16D size#23 needle ran it through the machine seemed to run just fine but when I did a back stitch to test it got a little mucked up. Any ideas on how to fix this? Also i see the knot on the bottom of the stitch on the back, does that knot need to be up into the middle of the leather? if so how do i adjust the machine to do that? Also how can i adjust the foot pressure to lighten it up a bit so it doesn't push so hard on the leather? FRONT BACK Thanks! Consew 206RB n00b! Quote Share this post Link to post Share on other sites
R8R Report post Posted October 20, 2018 Not enough top tension or Too much bobbin tension or Machine is timed for a much smaller needle/thread combo or ?? 206RB owners will be along soon to make further assessment. In the meantime, your top thread tension is weak. The joining lock of each stitch should meet in the middle of the material. Your bottom tension is higher than the top so it is pulling the knots to the backside of the material (run a fingernail along a stitch and you will feel the nubs of each knot. Crank up your top tension till it starts to pull those knots up top, then back off till it sets them in the middle. This will give you a sense of the range of tension you need to work with for this material. The very best thing is to find the correct tension with 2 layers of similar materials first. Get the knot in the middle of those layers. Quote Share this post Link to post Share on other sites

I really like this rather than suggesting adding small adjustments until it barely gets the knot in the middle. Becoming comfortable and confident in turning the tension knob is a good basic skill that will benefit new sewers with any sewing adventures down the road.

myjtp Report post Posted October 20, 2018 Alright so I spent a few hours and i THINK I finally got something somewhat usable. I tightened the bobbin a bit then tightened and loosened the top stitch and it seems to be going pretty consistent now. Let me know if the stitch is ok? It's not very straight but I'm still practicing. Does anyone know where I can get an edge guide for my Consew 206RB? Is it normal for the top thread to shred up a little bit? I see some of the fibers are standing up a bit. Do i use a lighter to burn the edges a bit? Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted October 20, 2018 Sometimes the needlebar thread guide gets a groove worn in it from the thread & will cause this,you might look @ the hole on the inside foot(on the bottom side) it can also get grooved from the thread.We stock edge guide feet & a drop down guide too.

Alright after further inspection there might be a few points that are causing the thread to fray a bit. Apparently, I'm missing a square piece of felt that goes here the thread rides on.. anyone know where i can get one? or roll my one? Here are other pics of the plate ( which looks to be another part that needs to be replaced which could cause fraying ) Here are a few more pics to check as well Quote Share this post Link to post Share on other sites
Ferg Report post Posted October 20, 2018 Check all the paths where the thread travels for what you see on your machine in these photos. Some times you can clean them up with a jeweler's file. Best? Get the new parts from Bob Kovar. Ferg Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted October 20, 2018 Holes can be smoothed with round abrasive cord that's sold on metal 2 piece rolls by tool supply businesses. It comes in various diameters. Quote Share this post Link to post Share on other sites
