Wooden mudguards

I'd buy them if they had compound curves. I'd like to look nice AND stay dry.

I could just make my own. I made a strip laminated table from red oak many years ago at collage, it's not too tricky if you've got a decent workshop. Just get your veneers, soak in hot water, put into the former for a few days, take them out, glue them together, put them back in the former, wait for a few more days, take the piece out and tidy it up.

Making the former would be by far the hardest part.

I'll add this to the list of several hundred DIY projects that I am yet to commence.

The former could be a bike wheel with a nice big tyre in it.
Inside one of those vacuum bags you can buy especially for moulding plywood.
