Repairs to the damaged sander continue.

This week the cap with the severely damaged was repaired.

After a lengthy discussion it was felt that a repair similar to that performed on the valve body was best.  The cap was mounted in lathe to cut away remaining threads.  A bushing was then machined with threads on its OD.  The Bushing was pressed into place to finish the repair.

In the attached image the repaired cap is inverted in left passage.  The repaired threads in valve body are on right.  The sand passage is heavily worn.  A sleeve can be seen inserted in the passage.  This sleeve will be epoxied in place at a later date.

Today the fourth hole requiring lead was filled in the second sander valve.  Three other holes that were filled last week were drilled.  Drilling of the fourth hole was started.

The protective coating of paint that had been previously applied to pins on the right side of drivers 1 and 3 was removed and a series of measurements taken.  The outside diameter and length of the old bushings for these pins were also measured.  Drawings will be constructed prior to any machining.

The first piece of bronze was set in place on the barn's Leblond lathe.  Machining of the first bushing could begin next week.

The heavy engine hoist has been returned to the barn.  The hoist is needed to mount rod bushing material on the Leblond.

All of the yesterday's crew spent a good portion of the day at trolley barn yesterday. In addition to work mentioned regarding 2479, several other things took place.

Bill and John Z. continue to beat on HSJ's yellow forklift.  The beast continues to quit running after about 30 minutes of operation.  I'm not sure as to the end results of their efforts.

Earlier in the week, I looked over SP1215 and found that rods and other polished metal was in need of work.  Larry and Denis spent the day on this task.  There is more to do here.

Also more grass cutting at restoration site.

April 6

After three full months of kicking repair ideas, experiments and machining, repairs to the sanders are complete!  This past week repairs to the final port were completed.

Shown to the right is the body with repaired caps.  The left port required a new lead liner.  The right port require a more extensive repair.  Sand had cut away the lead liner and a good portion of the valve body wall that held the liner.  A sleeve (bushing) was machined.  Lead was then poured to fill the sleeve.  The sleeve was drilled and then epoxied into place.  The top of the sleeve and lead liner are obscured by the gray epoxy.  Also note that there is a plug screwed into the left opening at about the 1 o'clock position in the left opening.  This plug is at the 11 o'clock position in the right opening.  The threads in this hole had been completely destroyed.  The wall was not heavy enough to support a larger plug.  The solution was to machine a plug and epoxy it into place.

This is the same valve but a side view showing new air nozzles.  Both valve bodies received these.

Boring begins on the first new rod bushing on the trolley barn's Leblond lathe.  This work will be on going for a good number of weeks except for next Saturday as projects master mechanic will be away.

Other tasks: More grass cutting. At this time of year, its a weekly task.  PM on forklifts and other equipment.

April 20

Multiple measurements of the Number 1 and 3 pins have been taken.  Measurements of the outside diameter of the old bushings have also been obtained.  One set of measurements of the rod bores for these pins is also complete.  With this data drawings are being constructed for each bushing.

Machining of the first rod bushing continues.  Inside diameter is complete.  Outside diameter is in work.  Trolley barn's LeBlond lathe is being used for all work.  Lathe is performing well.  For those wanting to see this work, the process should be under way by 10 AM most Saturdays.  Clean up begins near 3 PM.  Work is occasionally performed during the week but not on a set schedule.

Decision has been made to move the locomotive's cab back to the restoration site.  The cab has been stored under cover for a number of years behind the trolley barn.  Having the cab at the restoration site will provide work for volunteers. Yesterday the cab was loaded on to a trailer.  Trailer will be towed to site in the next one to two weeks.

Clean up of SP1215 running gear continues.

April 27

Bushing for the rod/pin on the number one driver, left side is nearly complete.  All that remains is to cut a radius on the inside diameter of the flange end to fit the pin.  Machining of the next bushing has begun.

Today most of the pipe mounted on the tender for the train brake air line was removed and inspected for wear.  It was felt that this was necessary when a large hole was found in the tender's brake line.  At least one small area requires pad welding to return this line to service.

More grass was cutting at the restoration site!

This morning the locomotive's cab was moved from trolley barn to locomotive restoration site.

Prior to any work being performed on the cab, a restoration plan must be created and approved by Art, Jack/myself.

Some time back a large quantity of fir was obtained for the cab liner. This material is at the trolley barn.  It will require some milling for use.
