Progress for Week 3 of Building the Roaster

2012 May 3

This week, the machining of the bowl was completed. The edge was milled to exactly 36″ in diameter on a vertical mill.

Next, the bowl was sent to the QC lab for inspection. It was tested for concentricity.

Extremely accurate measurements were taken at the area where the hub will attach. These measurements will be used to do a perfect match in machining the hub.

The main bearings for the bowl shaft arrived. They are high-temperature bearings since some heat will be transferred down the shaft.

The bowl drive shaft has been fully machined with a threaded end for the hub.

The opposite end has been machined down and keyed for the coupler to the drive motor.
