Thanks for the words

i know enough to be dangerous anything else that happens along the way is pure luck and s surprise

I'm only an amateur compared to most on here, but I think your top tension needs to tighten a litle to bring the knot more central in the leather.

Thanks,   How tight is to tight?  
it is as tight as Dicks hat band right now

The thread exits the thread tree goes through the post on the rear of the machine up to the front

it turns a 90 degree turn in a tension disc

Travels down to another tension disc bwhere it contacts 90%

ip to the thread take up

down to the needle via 2 rings

I think as it comes down from the first tension pulley to the second, it should go direct, not around the 'hook'. Once around the botttom tension disc, that's when you go through the bottom hook, and check spring (That appears to be missing).

Are you sure it's seated into the tension discs, and not just sat around the edges. (If they're too tight, it may not be all the way 'in')

Are we allowed to link to You tube on here ? If so, look at this, about 1:30 in and onwards.

Here's the threading,your missing the check spring adjuster & screw on your machine

[Frodo]

What is that word?   Cobbled?

lol. Well it is not factory specs it is cobbled together but it works 

I installled the check swing tension thingy

  I had to use a screw from a bobbin case spring .  And s tea cup hook.  
 

going to need new springs, screws 

Most aggravating thing I have ever worked on. I had to use needle nose pliers just to hold that little sob (screw) 

[Frodo]

Installing the check swing tension helped out a lot, but I am having an issue with the adjuster fitting

correct me if Iam wrong but the only thing holding the adjuster in pkk look ace is one set screw?   My issue is the back side of the adjuster does not want to stay in the grove,  it wants to raise up. This causes a gap between the rear disc and the tension release hook. It (tension release) wants to catch the adjuster

On a typical machine, when the manual foot lift is up, the tension disks on that end tensioner should be loose so any comparing of thread tension should be done with the foot down.    With the foot up, the thread should pull through relatively easily. 

I notice you have the tensioner screwed all the way in. Makes me wonder if you're not factoring in the release when the manual lift is up.  It's possible for the tensioner to be too far into the machine so the tension disk are always in released state even with the manual lift lever down.    On my Juki, there's a little pin that connects to the lift lever which pushes the disks apart while threading.  If the tensioner is set too deep into the machine, this pin will open the disks even with the lever down.  The fact you see the tensioner move after you tighten it, suggests, you're running into an issue like this. 

I think you should loosen the tensioner to maybe 1/2 tension. Then unscrew the set screw that holds it in place. Then slide the tensioner in and out till you feel some contact. If you push it in more, does it release the disks?

Listened to you Quade

backed off the tension and rerouted

thread plus built a top tensioner

the results are a tight top /bottom on a stitch line

I am not sure the ck tensioner is installed correctly but it is working  I think

The check spring you've put in - is it actually moving? It needs to start in the position shown in red, then move up to where it's shown in your photo. It returns to the red position, keeping the thread tension when the take up lever drops down again..
