The second pattern is for the engine mount. To get over the wracking problem, the engine is bolted to two pieces of steel angle which Father has already made. The right hand angle is bolted up to the inside of the sub frame but the left hand swings on a centre pivot to avoid loading the crank case. This casting is for the centre pivot and bolts to the middle of the angle.
As usual, Steve started with pieces of MDF which were cut, sanded round and glued together before adding fillets with Isopon again.
The filler was again dressed with glass paper.
