Wishing to add some detail to the wheels for my Wessex build I thought about how to better do this using a JLC saw blade I had. After thinking through a few iterations I decided to first make the simplest tool possible so with some acrylic cut for the base and some rectangles from various thicknesses of plastic card that were just a little narrower than the blade. Drilled a couple of 5mm holes through all the parts that lined up with those in the blade, and finally rustled up a some M5 bolts and penny washers. Ta-da!
... keeping the wheel flat just gently rub it against the blade, then flip over and do the same for the other side. Add or combine shims for additional grooves.
Simples (who need 3D printing
)
Wedging a suitably sized stick in the hole make it easier to handle smaller wheels. Or if the wheel rotates you essentially rivet the wheel which could add some interesting texture.
I've ordered some wingnuts or convenience but even hand tightening the standard nuts is more then secure enough.
