Making a steering wheel.
The Morgan 4/4 already had a wood steering wheel the Mota Lita but it is really substantially aluminium alloy with only the rim made of wood and that is plywood with little intrinsic strength, having laminations that are radial and so adding no rigidity.A recent wandering through a classic car show sparked the idea, seeing a 1914 Hupmobile with its wooden spoked wheels and a crude wooden steering wheel that has stood the test of time.

Having already made a few wheels for toys for my young grandchildren I knew it could be done for the Morgan and set about the job with a wooden mould onto which the timber would be built up in laminations approximately 1/16th in thick. Cascamite resin glue was used for the outer rim and its a sticky job requiring glove protection for my hands.
Firstly the laminations are cut and planed to size and steam softened over boiling water in a pan. Allowed to cool and held to the mould with crocodile clamps. The tricky bit is ensuring full contact between the layers. There are probably better methods than mine such as vacuum bagging or wrapping with string to exert sufficient pressure. But this was to be a prototype and seems to have succeeded but admittedly, could be bettered.
Spokes most of which were rejects. Note the sharpened one drove through the redwood plank. |
