Nope, not taking the screws out.? Seriously while it works copying it would
how I torture you.? Everything is built from my not near 55++ years
accumulating junkbox.
The idea is not original.?
You have images of the screw and coil assembly and asume the screw has a hex nut.
Now if you put a deep socket with the correct hex inside shape you can rotate the screw
in or out without the socket doing same.? Imagine the socket on a shaft with a bearing
and a knob.
IF the screw only had a pin at its end we still have something we can? grab and turn,
so if a tube with a long lengthwise slot were slid over that pin we can turn the screw
but the tube does not have to go in or out.
There are several ways to vary that.? The kit described and sold uses a threaded bushing
as a fixed rotary element with the knob.? A screw threads in and out of it when it turns.?
The intermediate board with nut prevents the retained threaded screw from turning see?
the manual for how that one works.? ?
One of many ways to solve this problem.? The real trick is to do it with easily obtained
materials and limited tools (hobby saw, files, drill).? FYI the slotted tube was done using
a Dremel tool and a narrow cutoff wheel, very carefully to keep it straight.
