The fenders are made from 3 layers that are around .1 or .09" thick. I get the wood from an exotic hardwood supplier from michigan. It is sold as veneers and is usually around .125" thick. I inherited a micro planer that allows me to thin it by sanding.

There is no need for steaming, I just glue, bend and clamp against a form.

As for the hardware, I make it myself. Although you can get and use replacement hardware from existing fenders. My hardware is constantly evolving, but I am using stainless from online metals for the stays and brackets and a bolt I drill out from mcmaster carr.

Let me know if you have any other questions
