SP2479 Saturday, June 22

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.

SP2479 June 15

The day began by installing the right front side rod. Expectation was not high at being successful. There was no way to predict the position of driver 1 and 2 to each other. The drivers were install with the old bushings in place. Since these old bushings were sloppy on all pins, it was thought that pin position to each other may be slightly off. The rod was pushed into place on the front pin. When it came time to push the main pin's floating bushing into place, all were rather surprised when the bushing slid into place with minimal effort!

Next the R3 bushing was pressed into the rod and the rod installed. The only issue to be resolved is alignment of the knuckle pin's nut to the locking rod grooves, otherwise work on the right side rod set is complete.

Machining of L2 bushing for the left front side rod will begin this week.

SP2479 - June 7

John Ezovski

Rod bushing work is moving forward. The three right side rod bushings are finished. Next week R3 bushing will be pressed into its rod. R2 bushing is a floating bushing. It simply slides into place assuming the driver pins are in the correct position.

The R3 bushing required about 11 hours of machine time. R2 bushing required signficantly more time because of the grease holes. Each hole is precisely located, then drilled followed by chamfering on both sides. Close to 24 hours of work was needed to get the bushing to its finished state.

Repairs to the cab are on going. Presently damaged sections of the "rain gutters" are being carefully cut away. When this work is complete, new material will be welded into place.

Lots of grass cutting and tree pruning. Site looks pretty good.

SP2479 - June 1

John Ezovski

Lots of rod bushing work. By far the most significant completed task was locating 21 grease holes in the bushing for the right side's front side rod main pin or R2.

All of the main pin bushings float on the pin and in the rod. Grease is injected threw the middle of the pin and out threw several grease passages in the pin to surface of the pin. This grease then passes threw these holes to lubricate the area between the rod and the bushing. These grease passages are laid out in a precise manner which allows for grease to be dispersed to the entire area between the pin and the bushing.

Work on the bushing for the right side's front side rod number 1 driver pin or R1 was completed. The final piece, a ring which prevents the bushing from being pressed out of the rod during operation, was pressed into place.

Next bushing to be cut will be for the right rear side rod for number 3 driver pin or R3. The blank was mounted in the Le Blond lathe at the trolley barn. Machining of this bushing will begin this coming week.

There is much work to be performed on the cab. All surfaces require cleaning and painting and is on going. Several small areas of the "rain gutters" over the cab windows are in need of significant help. Those repairs began today.

The absence of rain has reduced growth of grass and weeds, however, the site was looking a bit rough. Lawn mowers were put to work but there is more work here.

Machining of rod bushings continues. Driver #2's bushing for the side rod is coming along.  All that remains of the work on the Le Blond is finishing of the bushing's flange end.  Once that work is complete, the bushing will be moved to the restoration site and grease holes will be located and drilled.  Lots of work here.

Today the right front side rod was test fit.  On initial attempt at mounting the rod, number one driver pin would not accept the rod.  This was expected.

During the week, the bushing was pressed into place and the inside diameter of the bushing measured.  The inside diameter of the bushing shrunk a considerable amount.  Dimensions of the pin were checked.  It was doubtful at the time that the pin would accept the rod.

The bushing was pushed out, machined and pressed back into place.  Rod slid onto pin, as it should, with minimal effort.

Lots accomplished yesterday.

Machining of the front, right (R1) rod bushing was completed.  Two of eight bushings are now complete.  Because of the time of day, the bushing was not pressed into the rod.  That work should be complete next Saturday.  The next bushing to be machined will be for the front side rod, main pin.

Some pad welding on firebox roof sheet was also completed.  Two areas are complete and one partially finished.  There is one more large and one small area remaining.  Next week the completed areas will be measured for thickness and Form 19's generated.

Clean up of the cab's exterior surfaces has begun.  Because the cab has sat for a very long period with primer only on the exterior surfaces, the entire exterior must be wire wheeled.  Cleaned surfaces are then covered with primer.  Paint will follow.

Thanks to all that participated.

SP2479 Saturday May 4

John Ezovski

Machining of the first rod bushing, L1, is now complete. Cutting a convex radius at the entrance to the inside diameter was the last step )see image-1). This radius matches the concave radius at the wheel end of the driver's pin. The bushing is seen sitting nicely on it's pin in image-2. Next the bushing will be pressed into its rod. Before this can happen several things must occur.

First the rod must be moved from its storage spot in the trolley barn. This man take place this coming week. Our large hydraulic press in the outside shop will be used to insert the bushing. The little Hyster forklift is needed to carry the rod to the press. Today the right front tire on this machine was found flat. Location of the leak was identified. This coming week the inner tube will be patched. Hopefully the little forklift will be ready next Saturday.

Once the bushing is in place, a thrust ring will be press on the non-flange end. This ring prevents the bushing from being pushed out by the rod's retaining nut during operation. Some machining to the thrust ring may be required. With this work finished, the rod will be returned to its proper home!

Machining of the rod bushing for the right side number 1 driver pin is well under way. Work on this pin should be complete in the next one to two weeks. This is dependent upon how things go with the first bushing. The next large piece of bronze to see the Le Blond lathe will be for the bushing for the left front rod number 2 pin. It was decided that work on the left front rod will be completed first. We will then repeat with the process for the right front rod. There are many weeks of work in front of us.

While rod bushings are in work, there is another big task waiting. Most know that the cab is now at the restoration site. Work on restoring/repairing the cab can begin once a detailed plan is created. Those that are looking for a task, here it is!

Also today, the locomotive and tender were rolled to keep journal surfaces from corrosion.

March 2

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.

March 30

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.

Rod Bronze Has Arrived

John Ezovski

The rod bronze has arrived.

1150 pounds of bronze arrived at the trolley barn early this afternoon (March 27).

The carton was opened for inspection with no issues found.  I took measurements of the material I could access (some of this stuff is pretty heavy!).  Numbers I obtained easily meet those provided.

The carton is now stored in the trolley barn.

SP2479 Status - March 23, 2013

John Ezovski

Today lead was poured into three of the four sander valve body ports.  A number of different methods were discussed as to how to create new lead liners for these ports.  Most of these ideas required significant creativity.  The final solution turns out to be the simplest: fill the hole with lead and drill out the required opening.  Three of the holes have been filled.  Next Saturday these holes will be drilled.  If the resulting sleeve is acceptable, the fourth hole will be filled and drilled.

Rod bronze should now be on order!  This week a check was mailed to the vendor.  Upon receipt of check vendor was going to begin manufacturing the required material.  Material should arrive towards the end of April.

Warmer weather and small amounts of rain require site grass/weeds be cut weekly.  Properly operating lawn equipment is rather helpful.  Site continues to look good.

SP2479 Progress Feb 16, 2013

John Ezovski

A bit of machining on sander valve on Bridgeport.  An attempt was made to mount valve on Leblond lathe. Issues were encounter with the plan.  Another attempt will be made next week.

Some pad welding on firebox roof sheet.  There are a number of deep gouges in the roof sheet on right side in area of cab bracket.  Pad welding of these areas began today.

Site clean up. We keep the site looking pretty good, but there is always ways to make it better.  A bunch of "detail" stuff was completed and grass cut.  Place looks good.

Progress is being made with acquiring bronze for rod bushings.  Order could be placed this week or early the following week.
