Rex 26-188 Jammed up

[DonInReno]

Now I’m curious - it’s a pretty simple design so it’s probably something obvious once you see it.

Rex machines are often (always?) made by someone else and simply rebranded so I started there.   A quick search shows the Nakajima TDU N62 as the same machine - there’s a lot more information on the Nakajima.   The design also appears to be based on the Singer 16-188, which there is even more information on.    I’m pretty sure Consew also copied the Singer, but I don’t know the model number off the top of my head.

Anyway, the singer parts manual was the easiest to download and the attached page shows the presser foot lifting lever and related parts.  It wouldn’t surprise me if the presser shaft clamp #1823, or knee lifter gizmo #4725 is either broken or not contacting the lifter knee/lever for some reason.  It’s not uncommon for production users to really jamb on the knee lifter and over the years those parts simply get fatigued and break.   

As far as the presser shaft bar contacting the nut - I’ll bet it’s not the correct nut - Nakajima photos show a very thin looking nut.

Hope that helps.

There’s also a Yakumo TDU-N62 that looks just like the Nakajima.   It’s interesting to see it in white - at first it looked like a new machine, but it’s probably a well done paint job.   The painted over screw heads gives it away.

Theres a YouTube video on this model talking about setting the presser feet so they walk correctly.

Maybe the (back) aka pressure bar is stuck?

You see this a bunch with old machining tools re-sellers too. They buy a rough lathe or mill at scrap prices, slap a coat of paint on it then sell for decent coin.

Update

The presser foot bar I find is binding up. I ordered a new one

The flat bar was binding up where it went through the outer case of the machine

I polished them till they slide smoothly. Then I noticed the top of the flat bar was touching the cover plate. And it looks like that cover is not original. So I cut a slight notch to clear the outer housing

I found in the list of singer parts a set of tension plates that are missing. Part #2111   Heads Up Mr Bob  I will be ordering   even without the correct tension I threaded the machine and tried it out

the bobbin was picked up on the first try and it sewed a 12” stitch line

I just spent 3.5 hours getting the hook Timmy  right

if any has any tricks, i’M all eats

What's it not doing?

1- The needle and the hook need to pass next to each other as closely as possible without touching so, you might need to move the entire hook assembly towards or away from the needle.  The hook actually passes inside the cutout on the needle.  On my 211, there's two clamp screws and the actual gear needs to be loosened so I can move the hook either closer or farther to the needle. Then everything needs to be clamped down.  If you know where the hook is, you automatically know the orientation of the needle. 

2- The hook should be 1/16th of an inch above the needle eye on the upward stroke. So take the needle to the bottom, then as it starts to move up, the hook needs to be 1/16 above the needle eye.

Good stuff!!!!

Thank you Constabulary

According to the manual Constabulary provided (Thank you). When the eye of the needle is at its lowest position it should be on a level line with the tip of the hook 

I am there, the needle picks up the Bo in thread first try

but when I sew all I get is loops under the leather with no horizontal bobbin thread

Remove the leather, and the needle picks up the bobbin first time
