Hi, I am Bob VE3UK from Pyramid Machinery which is the parent company of MagLoop and Monarch Capacitors. Today I am giving a brief introduction on how you can easily make your own butterfly style variable capacitors using the plates the I produce using CNC Laser technology. To get an idea of how many plates you may need for a given required capacitance maximum, please visit my Monarch Capacitor Site's calculator here: http://www.monarchcapacitors.com/calc...
