Lots accomplished this week.

Machining of the bushing for the main pin of left front side rod (L2) completed. The rod was installed on the front pin. Attempt at pushing the L2 bushing into the rod and on the pin failed. It looks as if the number 2 drive must be moved forward a very small amount. Slipping the driver forward was left for next week.

The blank that will become the bushing for the left rear side rod number 3 driver (L3) was set in the trolley barn's Le Blond lathe. This coming week machining of this bushing will begin.

The feed water heater and air pump were inspected. These objects were placed inside a small garden shed several years ago. Both units are in good shape with no evidence of corrosion. Polished piston rods were coated in oil and crates secured in the shed.

The two 6 foot long 8 foot tall doors at the back of the outside shop were cleaned, primed and painted. These doors were covered with the remnants of a garden shed about two years ago. These pieces of sheet steel were a number of different paint colors which did not look very nice. From the Old Tully Road, these doors now look pretty good.

There are two similar doors are on the opposite end of the outside shop. Until recently these doors were covered with plastic tarps. Tarps were removed due to their deterioration. A stack of various lengths of used galvanized corrugated sheet steel has been obtained at a good price (free). The front doors to the outside shop are now covered with this used material. In the future, the doors will also be painted.

Thanks to all that participated.

June 26 Update

Saturday the crew was not able to insert L2's bushing onto its pin/into the rod. It was thought the wheel was possibly out of position.

This morning I thought I would get a head start on the weekend by taking a measurements between the L2 pin and rod. With this data it could be determined which direction and how far the wheel would have to be moved.

To help make the task easier I machined a piece of 7/8" round stock down to a dimension .002" smaller than the clearance between the wheel's pin and rod. A bottle jack was used to raise the rod off the wheel's pin. The machined piece was inserted at the top of the pin and the rod lowered on to the machined piece. The rod was then raised a very small amount to allow the machined piece to be removed. Measurements were then taken at the cardinal points using a small spring caliper. There were no significant differences between the four points.

At this point, I tried to insert the bushing onto the pin and into the rod.
