The pictures are examples of how it should not be. Uwe has some excellent videos detailing how to adjust timing / whole machine! Timing is not correct. Check to see if the safety clutch needs to be reset. Second video is to set timing.

FSForge, Any progress with the machine not picking the bobbin thread?

Found this on Supsew.com site. Shows timing for a DB2-B792. Don’t know how similar it is to your machine.

My Consew bobbin holder is similar. Thread should be loaded CW. Thread should come out from under the tension spring on the end.

Needle looks bent. Machine is not timed correctly.

Looks like the ratchet wheel needs to be moved over to line up with the button. Make sure the set screw lines up with the groove in the shaft. You should be good to go!

Welcome aboard! Had many of the same questions with my machine. Lots of good info here, just have to keep searching and reading! I have the Consew 226 that is the same as the SEIKO you have. The reverse lever is spring loaded , you have to hold the reverse lever down while reverse stitching. Here is a link to adjust the reverse stitch to match the forward. https://leatherworker.net/forum/topic/76115-consew-226-reverse-stitch-length-adjustment/

I’m refurbishing the table top that came with a 206RB-1. It is a Singer top with Singer knee lift. Trying to figure theplacement of the knee lift. I have the roller lever from a 206 RB-5 on the machine. Using the assembly drawing (lower) from a SEIKO STH-8BLD-3, the shaft center line is 210 mm. Also found a drawing (top) for a 206RB-1, center line is 182 mm. What placement should I use? Can anyone get a measurement from their machine? Thanks. .

Gymnast, Thanks for that info. Never realized about the relationship of needle size to diameter. I thought it had more to do with the hole size that thread goes through. I guess it’s a combination of both.

Pierick, I am having the same problems with doing all the adjustments on a 206RB-1. Machine was sitting so long, had to do some removal of parts to clean it. And yes the RB-5 doesn’t have all the same components, making it difficult to service it correctly. Thanks for solving one of the things I needed to make an adjustment to. Found this info, First link from Keystone Sewing is for a SEIKO version of a RB-5. Good info. https://www.szwalnicze.com/cat_consew/consew_204_206_208.pdf https://www.supsew.com/download/Consew/Consew 206RB Operating Instructions.pdf

Here’s what happens when the thread goes around the pin! This is what’s on the 206RB-1 I just bought. Don’t know how long it takes, but it will wear.

Consew 206RB-1 I just acquired has a worn tensioner pin from routing the thread around it.

Thanks! Plan was to get both , but don’t have room for it.
