Wood Fenders 2

The first bent wood fender came off of the form today. Considering how much epoxy was squeezed out of the wood and went everywhere, I consider coming off the form to be a very good thing.


There was more springback in the laminated wood than I was expecting. I will have to modify the form, or even make another form to end up with the right fender shape for the tire size. The wood ended up springing back around 8%, so I will try making a mould that is 8-10% over bent next time.

The three layers of 1.5mm ash are stiff enough when laminated. This gives a 4.5mm thick fender that is nice and light. Once it is braced to the bike through the brake mounts and by wire to the axle it will be stiff enough to ride with.

Because the fender radius is now too large it does not sit as close to the bike wheel as intended. The fender will also be trimmed thinner to look more proportional to the bike tire.

Wood Fenders 1

Heather recently got a gorgeous new bike, but for some reason it didn't come with fenders. We are now going to try to bend a set out of wood to keep her and her bike dry in what has been a very rainy Toronto spring.

The fenders will be lamination bent, which means that multiple layers of wood are glued together and then set to cure on a form. When the wood is taken off of the form, the layers are held in place with the glue and keep their shape. This type of wood bending is commonly used in furniture (think IKEA) and boat building (think of a boat),

The Fender Form

The form was made from laminated plywood with a backing strap for applying clamping pressure to the bent wood. The contact surfaces were then covered with gloss white adhesive vinyl so that any excess epoxy will not bond the fenders to the form.

Wood on the Form.

The first attempt will use three strips of 1.5mm thick Canadian ash. The ash is actually the off cut wood from the bent wood table that we made last year. Good thing I was too lazy to clean out that part of the workshop.

The strips of ash were covered with epoxy and then placed on the form. Clamps were applied from the center outwards, and the excess epoxy was cleaned up as needed. The epoxy will take around 24 hours to harden, so we will know how it worked out tomorrow and whether 3 layers of wood will have enough rigidity.

Designing Authentic Experiences

Core77 recently posted a great article by Willem Van Lancker that was inspired by this commercial:

The "quest for storytelling has become a cottage industry in itself; that every brand, product, and good must come packaged with a unique story or else it is valueless. In the past these stories were experienced firsthand—today we read them on placards and labels in stores framed as immersive brand experiences."

A good read, definitely worth 5 minutes.
