Shafts being nicked by setscrews is a common problem. The burrs make it very hard to slide bearings or collars on and off the shaft.
A better way to deal with it is to modify the shaft itself rather than the objects that must slide onto it. A flat spot filed or milled onto the shaft will allow the setscrew to bear hard on the shaft without leaving burrs that get in the way; it will also prevent the setscrewed piece from rotating at all, even if the screw gets a little loose.
Another way is to machine a smaller-diameter groove or "land" all around the shaft where the setscrew contacts it. This is good if you know just where the secured bit needs to go along the shaft.
These methods have the advantage of being easier to do than the relief in the secured piece, and you only need to do the one place on the shaft, no matter how many things need to slide over it.

The "extra" bolts might be to make an assembly that doesn't need to come apart, and is separately attached to the other stuff by the longer bolts. The overlapping washers are harder to explain....

In the image below you can see the groove or land in the middle of the shafts; this is where the setscrew for the collar goes. This shaft slips through a couple of bearings so it can't have burrs on it anywhere except inside that relief area.

It seems that it is a pulse principle. The one that I want to test is fully DC, avoiding foucault. And the FCEM is kept in a torus, then no FCEM lowing the COP.
I willl build the first one at minimum cost, the second one at maximum COP and the las one at industrial faisability level (maximum standard part and standard matérials).

Not much to add this weekend.
I did decide to remove the vinyl tape from the toroidal coils, in favor of clear adhesive, in order to clean up the appearance.

So I am watching glue set at this point. . .

Hi everyone,
This topic even haunts me at night.
I read almost all the posts and this morning I am very tired.
In conclusion, I ask you to be honest before I started to build this machine:
Who among you have built and managed to make the generator RomeroUK / Muller work?
I'm retired electronics with few resources and the expenditure must be justified in my budget.
I have an oscilloscope and low voltage more power tools.
Thank you for your confidence.
