Lehmann Striling Engine Ep. 3

The next parts for the engine being made are the bearing blocks.

For the tall bearing block, I used hot rolled steel bar. Milling the profile to full depth on the first op.

Moving on to the second side by milling away the remaining stock and finish to final thickness:

The top of the bearing block is tapped to mount the bearing cap.

The bottom mounting holes are drilled:

Counter bore from the top for the mounting pads. To be able to reach, I used a DA200 collet extension.

The short bearing block I had previously made. All it needed to be finished was a small slot as a cosmetic feature.

The bearing caps are installed, and bored out for the bearing.

The caps are then finished up by tapping a hole for the oil cups.

The last operation was to drill a hole in the blocks for a pin to prevent the bearing from rotating.
