Rex 26-188 Jammed up

[Frodo]

Last week I had to cut the needle bar out of this machine with a dermal. Ordered new parts from Bob rr at Toledo sew machine sales 

The parts game in and I started putting the machine together while having an eye out for any parts that may be damaged,

This machine sat outside in a shed for years

everything was going fine till I noticed the v walking  foot guide bar was not lifting when it walked nor did the lifting handle budge it.  So I took the parts out to have a look. Guide bar seems to be ok just dirt 

cleaned oiled and started to reassemble

the whole machine is jammed up. I looked inside where I was working and no tools or parts were left inside  what would cause this?  Before dismantling it was freely moving

 

[Frodo]

Found it, old needle gel into the hole and jammed it up

 

[Frodo]

Walking foot lift lever

what would keep this assembly from not working?

please excuse the dirty hand, When you play with oil you get dirty 

 

[Frodo]

With the foot tension adjustment knurl bob all the way down, I can get the foot to walk

still no lift on the foot raise bar assembly

suggestions ?

[Frodo]

this is interesting

the lock nut on the tension adjustment when in the locked position is in the way of the foot bar guide as you can see in the picture

 

 

[Frodo]

I am leaning towards 1 of 2 things

Rusted or bent

the guide bar for the walking foot

any professional opinions ?

I am just a plumber, and do not know squat about what I am doing

My only input, being unfamiliar with your machine, is that you need to find out where the adjuster is that lets you lower the position of the inside foot. The dropping of the inside "vibrating" foot causes the raising of the presser foot. If the inside foot doesn't make firm contact with the throat plate, and maintain it, the outside foot cannot lift. On a Singer 111 type machine there is a crank coming out the mid-back that connects to a knuckle joint that is adjustable in a curved slot to adjust the amount of lift. There is a large screw on the knuckle that when loosened lets me move the inside foot up or down., then lock it in.

Videos are blurry and shaky and do not show "the whole scene". Anyway - as far as I can tell you have installed the needle bar and needle holder incorrectly and the needle clamp screw probably blocks the foot when lifting the foot lever. With other words rotate the whole needle bar until the clamp screw faces right. But I only can guess here.

On my singer, what I call the primary foot, the one on the back, the shaft has two clamps attached to it.  One clamp is for the spring that's on the back of the machine which creates the primary tension for the presser foot and the other is what the hand lift presses on to push the primary presser foot shaft up. 

I'd probably take off the both presser feet.  Unscrew the tensioner thing on the top back,  Then see if you can get that rear shaft to lift up and down.  You ought to be able to release the clamps and pull it out of the top of the machine but, I wouldn't do that initially. 

The question is where there's a mechanical jam or if the shaft itself is stuck.  When you press up on the hand lift, the inner and outer feet should both lift up.  Either one could block you.  I don't know that machine so, I can only guess. 

I have a feeling the problem is in the thing that moved the feet but that's just a guess.
