Guide to make own fin with base fitting 10.5" box?

Anyone know of any good guides to make your own wooden fins fitting a standard bahne box. Taiyo surfboards used to have one but it’s been down for a long time. I remember most parts, just not how much of the base that was wood and how much that was cloth+resin.

This is how I do it. But others may have different/better methods.
