Next challenge was to install the sliding middle piece and to position it properly relative to the lever.
The first attempt showed that the gap between the lever and the piece was too big limiting therefore its movement.

So a big filing session after I managed to make the left leg of the body thinner allowing a much bigger movement.

With this sorted it was time to install the small stud that stops the movement of the lever. The slot of the lever has a tiny bump to hold it on the down position so it was necessary to install it with the correct diameter and very accurately. I succeeded and the feeling of the lever reaching the bump and locking is very satisfying.

So with this done it was time to focus on the sliding tube and its bearings.

I also drilled and tapped the hole for the retaining screw and checked that all slides smoothly.

With all this installed I was able to install it again on the phonograph and measure accurately the position of the front roller. As usual I died in blue the surface, measured, draw some lines, drilled, tapped, and when I was checking the fit of the screw it snapped...

So after watering the terrace plants to calm down I managed to drill out the broken screw and do an exact replica of it.

(Yes, the saw is even older than the phonograph)
So here it is, roller installed and turning smoothly.

And with this, the body of the carriage is finished appart from the retaining crew and tab that will hold the swivelling arm.

:lol: I'm also one of those that need to count up to 10 like Donald Duck before reacting to the accidents of life!

Big step for the humanity!

It works. Smooth as silk.

Still needs the stops of the swivelling arm shaft and nickel plating.

The horn is my 3D printed one that I use for tests.

Pedro, Fantastic job ! Great to see and hear it play properly after all this time. You must be proud of your workmanship in getting another machine back into playing condition !!
