After doing that remove Excessive solder and if you have wax to prevent Wire breakage melt wax on the PCB soldering part(side). Mark in the Centre of the sunmica under the box. Put some Araldite compound there and put some compound on the one side of the coil.

After I made this, it didn’t seem to move the way I liked, so I started cutting pieces off to change the balance. Your mileage may vary, so feel free to play around with it. The size ended up being: Cut Aluminium tube of 21cm and also put the point of Mark at 3mm from starting and Mark in perimeter at 6.5cm. Once you have the drill press centered for one piece, it should stay centered for all the subsequent pieces. Make the base column's one end curved for the fitting of hanging portion on it. Use plier and Abrasive paper to do that.

Take the copper wire, plastic paper or waterproof paper, scissors, small plastic tube, Fevikwik, paper tape, permanent marker, scale etc. Adhere coil in the Centre of the sunmica under the box and let it dry for two to three hours. ( For drying in less time put the box under direct sunlight.)

Solder the Potentiometer and LED with colored wires as we will put it separately from the main PCB for flexibility. Wait this was not the final step, the last step is to Correcting things and finishing project by giving it the final touch. Take two wires end of the coil and remove coating by abrasive paper or burning it. In the burning method, you may over burn it so I would prefer abrasive paper method.To get the bearings to make a nice tight fit, we need our hole dimension to be accurate. The bearings I bought are ABEC 5 which have a tolerance of + 0.000” and – 0.002”. That means my hole needs to be no larger than 0.250”. That seems easy enough, a ¼” drill bit measures 0.250”. True, but a ¼” drill bit never drills a precise ¼” hole. That’s pretty much true of any size drill bit. If a precise hole is needed it must be reamed.

Take Aluminum rod, which was previously cut and prepared. Put it in the hole we have created. The space between Top of the Tube and top of the box should be near to 157mm.(We can adjust about 5mm by bending rod so don't worry about that.) The model that I am going to produce is a kinematic sculpture, which runs on negligible electromotive force provided by electrical energy to run against gravitational force. Fix it on the box and keep preset out side by providing small space for it.(As my blue preset was failed I changed it with new one.)Use varnish or Fevikwik to make coils every turn stronger. Use Fevikwik or varnish after some layer of wire, so the wire can not jump out when we try to remove plastic paper. For varnish, you have to wait 3 to 4 days for drying coil. That's why I prefer Fevikwik.Yes, you can use Fevikwik for making coil stronger. If you have taken 50Gms wire than the wind all wire, otherwise remember that 38mm limit. Overall around 780 to 900 turn of wire is enough to create 8 to 10 Ohm resistance. If you do not know how to solder tell your friend, who knows how to solder, to complete this job for you.) Cut Aluminium tube in 17.2 to 18cm (16cm+1.2to2cm) to make base Column. Here 16cm will go upside of the box top and 2 cm will be given for support and it will come inside the box.
