Personally, I've found it super simple to create using the affordable Affinity software, using lines to make sure things line up and then importing into a font editor that does a lot of the kerning.
This way I can also create right next to references.
Most letters/numbers make use of one or more of the same basic strokes: the straight line, the curved line and the circle.
A method of getting a font with a consistent look is to reuse these strokes and modify as needed.
