The first step was to get the gear ratio I wanted and for this example, it is 20/40 or 1/2.
I wanted to use SOLIDWORKS and do as simple of calculations as possible. There are equations to calculate specifications of the bevel like the cone angles of the gears, tooth, face width and cone distances.
Recently, I ran into a scenario where I had to design some custom-sized gears and found a creative way to make a beveled gear that I thought I should share.
