The crankshaft is taking shape, with the latest job being the left handed thread to hold the oil pump skew drive. It’s a left handed thread so that the resistance force acts to tighten the pump drive. That way it can’t come loose, which would be disastrous!!

Once the crankshafts are finished we’ll be in a position to press the bottom end together together.

Meanwhile our friendly pattern maker is paying us a visit on Sunday. We’re hoping to get him fully on board for the project (i.e. get a good price for the job!!).

Next week more machines will be arriving, lot’s going on at the moment 😁
