5/15/2021 Work Session

Clayton has begun to install the new air lines on the tender frame. Leverett, Clayton, Rob Moore, and Dick reinstalled the emergency air dump valve so Clayton can set up pipe lengths, etc. Dick was then alone for most of the day doing the priming that has to happen on the #1 truck hardware. Roger came in to visit shortly but was unable to spend time with a brush. Dick did get most of the remaining heavy steel brake hangers and such coated.

We need a team of two or three people to primer coat (red) the #1 truck frame and all the coil springs, as well as the spring caps. This is critical to getting the tender frame remounted when the wheel sets are returned. I gave a tour to two railfans from downstate which ate up the final 40 minutes of allotted time for today.

5/8/2021 Work Session

Clayton got significant work done by bending the brake line pipe, using the original as his pattern. Leverett and Dick brought over the brake cylinder to the shop. The exterior needs to be cleaned with lead-out, primed, and painted. Again something for warmer days. Hanna attended to cleaning the mechanical lubricator and began by opening it for draining. She filled four 16-ounce yogurt cups with a mixture of water and thick, molasses-like oil. With advice from Bob and Leverett, Hanna got the lubricator steam heat lines out for cleaning and pressure testing. All in all, she got the most significant work completed. The lubricator was left draining into an oil pan for the duration, and you can be assured it is draining as you read this!

Bob laid out drill holes for the cab and measured steel. Paul V.S. interrupted hours of home fun in grading Calculus exams in order to drill heavy plate for tender riveting practice.

Dick cut apart the equalizer bars for one side of the trucks, so Leverett can replace the bolts and spacer bars which were not in good condition.

Bill has been up during the week and producing ribs for the cab interior wood lining. He has also been active in fitting the tender frame boards.

Whistle Grant Received

New England Steam Corporation (NESCo) has been chosen to receive a grant of $200 from the University Credit Union of Orono, Maine.  The grant will be used to cover the expense in casting a historically accurate, all bronze whistle for Maine Central steam locomotive 470.  The big passenger locomotive pulled the final steam train in 1954, then stood as a park feature in Waterville for 62 years.    The locomotive is undergoing heavy repairs in Hancock, as part of its restoration to service.  Unlike any other machine, the steam locomotive is an educational feast for history buffs, scientists, writers. and musicians.  The new whistle will be her active voice.   

NESCO wishes to thank the University Credit Union for their generosity in helping 470 be heard once more in the woods of Maine.

4/18/2021 Work Session

Not a huge cache of news for us today. Workers available were Paul V.S., Dick, Alden, Kendra, and Hanna.

Kendra was able to use the Lead-Out stripper to remove most of the paint on the tender doors removed last week. Paul, Dick, and Alden moved all chemicals, particularly flammables, to the blue tool container outside of the building. Most of these are petrochemicals and better stored out of the building. We completely emptied the two tool cabinets indoors and sorted the hand tools and power tools. For at least today, there is a sense of order in those cabinets. Alden was able to remove a rusty pipe from the loco frame and chip away at grease clots which have hardened on the steel for 70 years. We expect Brian Fanslau to come pick up the pilot truck and associated parts during the current week. Clayton Nowell is probably going to add the needed brake line to the tender frame in a similar time frame. Bill Alexander is back Florida, and will be bringing the remaining paint and primer up from storage at his home. Next weekend would be a great time to prime all the #1 truck components.

Rob Jones has been working on the big 470 model this weekend and has provided us with this photo of the midday's work.

4/10/2021 Work Session

On hand today were Dick, Bob, Paul V.S., and Alden. Our compressor is back, having had the bad water pump replaced. Bob and Paul worked largely on fitting the rear panels to the cab. This is beginning to take shape and is going to be quite a showpiece. Bob figures we are going to want to have some of our heavy-hitters on hand for cab riveting in about four weeks. I'll send out a special request for volunteers when a date is firmly determined. Alden and I removed the remaining doors and framing from the old tender tank. If the weather stays in the 50F range, we will want to use Lead-Out paint remover and then needle scaling to clean these, maybe next weekend. Most critical to advancing the tender project is the arrival of the new tender springs.

3/19/2021 Stoker Update

Bob received the custom made replacement piston rings to fit the new pistons and oversized bores. Also had a set of 8 soft copper gaskets made on a CNC laser cutter by an outfit in Kentucky. Cylinders are just about ready to be mated to the block. Then the pistons can go in. Still have some work to do on the packing gland assemblies. The valve glands are nearly ready. Piston glands still need final cleanup. All the cylinder studs were cleaned up and chased. Cylinder threads were all chased. New nuts for all the studs. Nuts are stainless steel.

3/13/2021 Work Session

Bob worked on the cab windows, Alden and Cully needle scaled, Alex scraped the recently washed out journal boxes for #1 tender truck. Paul V.S. cut the bronze propeller blades which will be turned into whistle parts.

Rob Jones brought up the partially constructed 1/4 scale model (3 inches to the foot) he is actively "growing". Rob also laser cut a "G" scale frame component of the 470; a portion of the model kits he will be producing for home hobbyists.

And we found a broken spring on 470.

Giant 470 Model Under Construction

Rob Jones (of Wooden Alchemy in Camden, ME) is constructing the 3" to the foot scale model of 470 for his museum store. He finished the drivers yesterday, and is now going to begin the valve gear.

2/24/2021 Work Session

Leverett and a limited crew used the giant crane to lift off the #1 truck frames today. Journals come off on Sunday, then it's needle scaling time.

2/21/2020 Work Session

Alden Burns, Cully Richard, and Paul V.S., worked to remove the left side air tank brackets, meaning both the left and right sides of the boiler are stripped insofar as we are capable. Small milestone in this. We need to photograph and label each remaining lubricator line before dropping them and putting in storage.

Truck #1 has been further disassembled and the individual parts require needle scaling. This truck sat under the coal bunker, and the acidic water did it no favors. We'd like to get these individual pieces scaled as soon as people can be available to assist. We have three needle scalers available, and cleaning them now will make priming, painting, and assembly, much quicker when things warm up. March and April are just around the corner!

Tim Steele made a terrific donation in the form of a safety shower and eyewash at the far end of the shop. Presently this is on a gravity feed reservoir. If we get water piped in this summer, it could be available for washing as well.

2/15/2021 Stoker Update

Bob DeWachter and his friend Dave Perreault have been hard at work on 470’s stoker. With the cylinder bores newly machined .0625” oversized, new cast iron pistons had to be made to properly fit the new bores.

The original pistons were machined castings. The new pistons were machined from pieces of G2 cast iron using a lathe and a CNC milling machine to make the piston cavities front and back. Check out the story in the photo captions below!

1/17/2021 Cylinder Update

Update from Bob:

Cylinders have been bored and honed to 1/16” over size. We now have two perfect, round and true bores with no corrosion damage.

First Photo: Cylinders coming off the precision hone machine with the bores brought to size and cross hatched to help the new rings seat.

Second Photo: Cylinders set up on a vertical boring machine. The right cylinder is bored, getting ready to set up over the left bore.

Third Photo: Completed cylinder refurbishment. No pits!!

Also received the material to machine new pistons to match the oversized bores. The material is 5 1/4” dia. x 3”long G2 Duracast cast iron. The two pieces weigh 35lbs together. Most off that material becomes chips.

Fourth Photo: Original piston sitting atop one of the slugs. Next to them is one of the valve connecting rods and packing assemblies.

12/29/2020 Stoker Update

Over the past few weeks, volunteer Bob D. unpacked the stoker project and got back to working on it. Still lots to get done, but he has been able to do some assembly work.

Bob acquired new crankshaft main roller bearings. These may well be the only roller bearings on the locomotive. Bob preheated the bearings to 150 F to allow a drop on installation.

Then the crankshaft was installed in the block.

The below view shows one of the crossheads cleaned up. Bob decided it merited a bit of fanciness so he jeweled the sides. Nobody will see it, but according to Bob, “it gives me warm feelings. Someday someone will open this up and say ‘hey look at this!’”

The first shot below shows the second main rod ready for install. Bearing clearances are excellent. The next shot is looking thru the top access cover at the crosshead. Wristpin head was polished to accent the jeweling.

Both main rods installed and connected to the crossheads. Turns smooth as silk. Compare this to the view of the same area when Bob started this project!

Spring Comes Early!

Leverett took receipt of the new tender springs today at the yard. NESCo received a grant from the Davis Foundation to purchase the springs, and here they are! Pictures detail the flat of delivered springs, the new springs set up with old pieces behind them, and a close up of how the springs will sit under the bolster.

To summarize, truck #2 is nearly complete, and we'll start #1 in the not-too-distant future. Nice way to finish the year!

12/19/2020 Work Session

Leverett, Al, and Ron made great progress. The brake rigging and safety bars are all back on the #2 tender truck. Still remaining are the pedestal binder bars, swing hangar keepers, new brake shoes and, of course, new bolster springs. This is a major completion before we begin tearing down truck #1. It signifies something completed and done as a "forever fix" for the 470.

11/14/2020 Work Session

Modest day in terms of crews, but Dick, Hanna, Cully, and Aldin were on hand and we did small things in a great way. Hanna really got into her projects by removing a great deal of debris from the steam chest and bagging it. A great deal of boiler compound, tons of cinders, and rust flakes. She and Dick then went to work removing all the rivets in the tender trim. We did not get a chance to complete the few remaining in the grab irons, as those will likely require heat, and the guys were actively using the torch.

Cully, Aldin, and Dick purchased another tank of acetylene, then went to work stripping the third course of the boiler. That went really well, including removal of the power reverse bracket and the drain plug, as well as the step-up below the sand dome. Unfortunately, Cully and Aldin are off for the duration of the Merry Covid Christmas break from University, so that will hamper further work until a new crew takes their places.

Leverett and Dick gave a tour to Jeff Jacobs and secured a grant from the Jacobs Family Foundation, which should cover #1 truck brake rigging repair and possibly more. If any remains, we have permission to use it for the completion of steel purchase for the cab.

10/24/2020 Work Session

A special note was the return of Hanna and Roger B., both of whom have been out with extended illnesses (not Covid related). These are representative images from today's work, but not all the images taken.

Bob D. made it up today and trimmed a little of the old steel from the original cab side, then engaged Roger, Hanna, and me while he used the hoist to place the new fireman's side.  It really looks good, clamped in place, although riveting will come a bit later.

Roger needle scaled the marker brackets and several handrail stanchions from the original tender.  Hanna applied Lead-Out paint stripper to the original coal board trim off the old tender, and then moved on to do the same for several other appliances, including the mechanical lubricator box and the speed indicator wheel.

Peter Violette made it up and disconnected several lubricator lines from the frame, just ahead of the drivers.  Peter later went on to help drain water which had collected on equipment stored outside, and also to grind away rivets holding the tender mounting brackets.

Our two newest volunteers, both from the University of Maine College of Engineering, Alden Burns and Cully Richard, removed 72 flexible staybolt caps from the right side of the firebox.  Dick used a cutting wheel to slice away four sheet metal spacers, and then the three of us removed the various steam pipes from under the catwalk.

If there was ever an illustration for the new cab steel, check out this photo showing the newly constructed cab left wall and the rear wall which is going to be replaced.

As mentioned before, Roger Bennati was able to make it in and help clean rust and paint from significant parts off the old tender.

Last, but certainly not least, Ron Jenkins and Tim Steele have spent several days mid-week to drill out the holes where rivets will tie the tender tank ribs to the tank sides, in the old-fashioned manner.

10/17/2020 Work Session

No pictures to share this time, but in terms of work, Jim, Cully (new student volunteer), Paul VS, and Dick worked all day on the firebox wrapper and the right side of the firebox. Left side is almost completed, excepting the catwalk brackets, air tank brackets, and single step. As a group, we removed both cab brackets, the steps, a number of pipe holders, one broken handrail stanchion, and 52 flexible staybolt caps. We repositioned two staging set-ups and purchased another tank of acetylene. 

We finished around 3:30, picked up the tools and locked up.  We were exhausted, but felt pretty good, having made some significant advances.

Ron obtained two quality step ladders for us, and has made significant progress in drilling rivet holes in the tender tank.

Poland Spring Company donated twenty cases of water (24 bottles each) for our crews to drink while on the job.

Things are moving at the shop, which, by the way, was dry, largely to Paul's efforts battening down the building skirt.

10/3/2020 Work Session

Alden, Jim, and Dick worked on the backhead all day, pretty nearly having stripped the left side firebox and complete backhead. One milestone was the release of the throttle lever, which we celebrated with a COVID-era gloved fist-bump. Jim polished the throttle rod and we loosened up the packing gland, in preparation to remove the castings. All the washout plugs were removed as well as several heavy brackets. 

Another milestone was met by our regular volunteer Alex Fogg and new engineering student member, Cully Richards. These fellows ground off the heads of the rivets, and punched them through, allowing us to remove all the grab-irons from the old tender tank. This involved some torch work as well, but it secured the original parts for the new tender body. 

Last, we have four safety posters which have been added to announce shop safety policies.
