Jigsaw head removal - The nut reinstallation

I have no official part names for the components on my 1955 Greenies jigsaw so I'll make them up.
The top jigsaw head is held on by a bolt screwed into a nut that is a couple inches deep inside the tube. When I removed the bolt, the nut dropped down inside the tube and I removed it from the bottom of the tube. Disassemble is almost ALWAYS easy.
Now, here's my predicament. The only way I can think of to get the nut back on and tighten is to first remove the female tapered component that is inside the tube, since the nuts bearing surface is the back of that component. Am I correct and if so, how do you remove the tapered component? Looks like it would require something like a spanner wrench to unscrew it but I am not positive, thus I post.

I've taken my old ER jigsaw apart to start the restoration process on it, but I don't quite follow what you're saying. Can you reference the part numbers from the owner's guide (image attached)?

Heath,
Mine for the 1955 Greenie is different than the ER jigsaw. Here's what it looks like.

You need to remove the eccentric tube that the square nut fits into. I use a clamp to compress the eccentric and then it should come right out of the arm.

To make sure I understand, your talking about the ~1/4" wide split shoulder that butts up against the end of the tube? If so, I'll clamp 90 degrees to the splits.

Tube has been removed per the instruction above. Here's pics that may make this thread a little more clear.
This shot shows the entire assembly with relative locations of parts. Notice how deep the nut goes into the main frame tube

This one shows compressing the eccentric tube and sliding it out of the main frame tube. Notice that you compress at a 90 degree angle to the slot.

Here's my semi exploded view showing all the components. This is how you would start the nut prior to re-inserting the eccentric tube into the main frame tube.

Thanks much SDSSmith for the instruction.

That is correct.....go easy, you are just trying to slightly compress the eccentric so that you can remove it.

Ready to restore my Jigsaw
What is the screw for in the back of the arm? The screw is missing in the pic above showing the disassembled unit.

If you are talking about the threaded hole on the backside of the arm (near the top), that is for the optional light. The threaded hole was on the original jigsaws. The newer jigsaws do not have the hole in the tubular arm.
