  1. For closure "Living History Days" at the Maine Forest & Logging Museum on October 5th & 6th was a great success! We had record attendance, fabulous volunteers and two wonderful, colorful Fall days here in Maine. I am pleased to say that the 1928 Lombard dump truck ran perfect! In fact it saved the day when our 10 ton Lombard - which we usually use to pull the 19 ton steamer out of the shed for steam-up, failed us with an electrical problem. Once sorted it it too ran faultless as well. Here is a video: Living History Day - Maine Forest & Logging Museum We still have quite a bit of a "to-do list" We think the forward/reverse lever once operated on a quadrant which went missing at some point. Without a positive lock it likes to jump out of gear. We solved it with a bungie strap but will have to fix it the right way at some point. It also is still idling too high which makes shifting a chore - when we turn the idle down it stalls out. It could be a fuel level issue in the big Zenith 77 updraft. Otherwise it starts, runs and drives as it should. Other immediate jobs include re-doing the fuel lines and installing the vacuum tank so we can climb some hills. We had a lot of fun acting the part of a 1930's road crew filling pot holes. We even got some of our visitors involved. Interesting sidelight: The cool mechanical hoist mechanism was originally marketed by Highway Trailer Co. In 1926 (?) they became part of Gar Wood. As in those wonderful, fabulous Gar Wood speed boats. Garfield Wood was a prolific inventor and (and power boat racer - Miss Detroit) made his mark developing and producing dump body hoists. Next October if your out touring around please stop in during "Living History Days"! Here we have not one, not two but three Lombard log haulers and tractors in operation - all made in Waterville, Maine My Daughter helping Herb Crosby pilot the 19 ton Lombard What better use of a dump truck than to take people for rides? Very cool hoist mechanism Giving rides on the 1934 10 ton Lombard. This machine was originally purchased by the City of Waterville, Maine for plowing roads Equipped with a big V-plow and double wings it could clear a 20 foot wide swath. At the time it was the largest plow offered by any manufacturer.
  2. According to Wisconsin for their T-heads (including the "A" used by Stutz and FWD etc.) with the engine warmed up at 1,000 rpm you should have 5 psi on the gauge. Its all about volume as opposed to pressure. They recommend Mobil "A" oil (whatever weight that is!) for light duty use. Stirling T-heads were good with 3-15 psi. Below is a Sterling Model "F" setup for a marine installation. i would suspect Locomobile would be similar.

  4. Hello Joe, Better to have more flow than you need than less! You can always add restrictor plates etc. to the water passages. Like I mentioned before - on the Wisconsin the lower water manifold pipes are 1-1/2 dia but at the flanges that connect to the blocks the opening is only 3/4" dia. in the pipe flange. I am pretty sure this was to slow the circulation down
  5. Hi Mark, Patty did a photo for me last year... fabulous work and very reasonably priced. I contacted her using the "send message" on her her facebook page and she was prompt getting back to me. I notice her last post was just a couple of days ago.
  6. As we move towards October 5th & 6th the crew has been hard at work getting things ready for "Living History Days" our last and biggest event of the year! Today they off-loaded the loggings sleds from the back of the Lombard dump truck and loaded-up with a bit of gravel. We will be using it to recreate a typical "1920's road crew" hard at work trying to keep the road in shape (the museum roads are all gravel so we actually have work that needs to be done!) We will also be operating our 1907 steam Lombard log hauler as well as the 10 ton gasoline powered Lombard. As usual there will be the Civil War and colonial encampments as well as the blacksmith shop up and running along with the water powered saw mill and our 1920 mill complex. Wagon rides, try your hand at rowing the batteau and a whole bunch of other things! http://www.maineforestandloggingmuseum.org/programs-2/living-history-days-2019 Fall colors, old machinery, wonderful people..... hope to see you there!
  7. You may remember back in July I posted about awakening the 1928 Lombard model "T" dump truck. Well thanks to the amazing generosity of the Breton family we now have the 1928 Lombard model "T" dump truck tucked away in the Lombard shed along side the two steamers and the 10 ton gasoline powered Lombard. Our adventure started Thursday night when I made the 2-1/2 hour drive down to Herb's. With the flatbed scheduled to be in Vassalboro at 8:00 am the next morning spending the night at Herb's and driving only a little over an hour made sense. As it was Herb and I were on the road at 5:45 am so we could be there in plenty of time to prep and awaken the beast. Fortunately thanks to Paul's prep work the beast fired right up without a problem. After a bit of frantic tugging on the steering wheel and jigging back and forth we managed to clear the pole barn without crushing Paul's blueberry bushes. I can tell you.... it's near impossible to turn the wheels when its sitting still! Here is the link to a video of todays adventure: https://www.youtube.com/watch?v=_ClQ...ature=youtu.be Anyway, by 8:20am it was loaded and on its way. Special thanks to Brandon our trucking guy! Unfortunately his GPS led him astray. He had set his GPS to follow the shortest route. However the "shortest" route was down a gated logging road. Fortunately we found him and once at the museum we quickly had it unloaded and tucked away in the shed. This gave us a good opportunity to look the beast over. We have fuel problem which is either gunk in the carb or sediment and scale blocking off the line to the carb at the tank. The inline filter we installed earlier indicates that there quite a bit drifting around in the system. We also need to get the battery cables sorted out and the battery tucked away were its supposed to be. We tried out the dump body hoist but about 2,000 lbs of Lombard logging sled parts in the bed precluded raising it up too far. However, it worked excellent. Driving this beast is interesting. It has essentially a heavy four speed truck transmission with the reverse blanked-off. Reverse and forward are handled by a lever down on the floor by the drivers left foot. It does give you four forward and four speeds in reverse. However, its an awkward reach to say the least. Meanwhile the lever for the hoist is a big reach over on the other side of the gear shift which would have a short person struggling to depress the clutch and work the lever. Lets just say its funky and neat and keeps the driver busy. The track system is really cool. Tension is held by a big spring stretching clear across under the cab and pulling on fulcrums which apply tension to front sprocket bearing frames. The sprocket bearing frames are not mounted rigid to the chassis but can slide fore and aft via slides and gibs. Anyway, our last event of the season is our "Living History" days on October 5th and 6th. Its also our biggest event. In addition to all kinds of other stuff we will have the steam Lombard out running around as well as the 10 ton gasoline Lombard and the Lombard Model "T" dump truck.
  8. Time will tell. Getting back to Ed's comments and a few thoughts. Our whole industrial landscape has changed from two generations ago and that I believe has certainly affected smaller industries that serve the hobby. For instance, here where I live the pulp and paper industry was king - it was the largest part of our economy for close to 100 years. Now its all but gone. Loosing the mills and jobs was only one part of it. Around those mills and that industry was a deep support system of small machine shops, fabrication shops and vendors who made bank on low volume but very lucrative work provided by that industry. The business model was much different. Now its high volume and low profit - you can't afford to cut into production by taking on low volume work that can potentially disrupt the production stream. Awhile ago I found a trade magazine from the 1920's for the coach and body building industry. What struck me was the hundreds of small specialty businesses that supported that one industry - from fabric to moldings to fasteners etc. to foundries to small and large equipment manufacturers for specialty tools etc. it was amazing. Now they are gone. Likewise heavy industries such as Alco, Baldwin etc. with their huge works manufacturing locomotives back in the day. Its simply bewildering the array of small and large vendors and suppliers that supported that particular industry. Again... its all but gone. Unfortunately it's not just our hobby that's affected. Back this spring I was asked to write a paper in support of a response to a request for a proposal by the Navy. They are alarmed - as they should be - in regards to our loss of manufacturing capabilities and supporting heavy industries. For instance imagine needing propeller shafts only to find out that there is only one supplier. Imagine what that would do to the cost and the difficulties that would arise if there was a sudden emergency? Thankfully at the time of our entrance into WW2 we had a robust heavy industrial base that could fairly easily and rapidly shift to meet war time demands. Then there is the cultural issue. For the last 20 years we have focused on every child needing a four year degree. As a result trade schools have struggled. For instance our local community college has a top tier, 2 year precision machine program - yet this year they only had two or three graduates! Its not that there are no jobs - industry can't hire enough! Its that kids are told that that four year degree is everything. Anyway... enough of my rant. I hope this project moves forward.
  9. As someone who has spent the better part of a professional career in engineering and now teaches CAD, Additive Manufacturing with a bit of CNC etc. thrown in there, and has spent a lot of time reverse engineering and fabricating quite a bit of stuff for clients, and my own projects using 3D printing, CNC Foundry techniques etc. I can understand and appreciate the problems they ran into in regards to info to work from. People tend to underestimate the amount of effort and particularly time required before the button is pushed and the 3D printer does its magic. Without a good 3D model or detailed drawings that clearly display design intent the task becomes doubly hard. A case in point - currently we are working to reverse engineer a very early impulse coupling. All we have to work with is the patent drawing. So far we have approximately 12 hours just on identifying the individual parts, the design intent and modeling in CAD four out of the 12 + parts (not counting fasteners). We still have many hours to go before we complete the initial 3D modeling, verify functionality, refine the design, develop the design documents (2D working drawings) before we ever get to produce a 3D printed mockup or CNC ready files let alone a finished product 3D printed or otherwise Below is a connecting rod we reverse engineered (and modified): I greatly appreciate their efforts and hope they will keep moving forward.
  10. Gary, Thank you for sharing the photos. I just received the new needle valve and seat etc. from Stan Howe for my Stromberg M4. Next up is indeed bushing the throttle shaft. I also need to do the same with the governor valve body as well since it went through a fire back in the day and is seized solid. Seeing how the shaft is setup for cutting the slot helps a lot!
  11. Hi Mike, I am not sure if this is any help but here is a brochure put out by South Bend in regards to boring and re-babbitting connecting rods. It illustrates some very good ideas for fixtures etc: http://wewilliams.net/docs/1936 - How to Bore Rebabbitted Connecting Rods - Bulletin 6-C.pdf Here is the rig David Greenlees uses with a LeBlond lathe. This image is courtesy his excellent website "The Old Motor"
  12. Unless there were other physical artifacts tying to a horseless carriage it could have also been used as a power plant for farm or industrial application. Beaver did indeed offer their motors for industrial/farm use and at least some models were used in a few early tractors. That's not to belittle what you have because again, its a interesting survivor that looks to be in good restorable condition.
  13. A quick search found not a whole lot on Beaver motors. However, they did market a fairly complete line and apparently offered motors to the marine trade as well including two cylinder opposed units. The latest I could find (again this was a quick search) for the opposed engines was 1910 (factory ad). However, there was one advertisement by a equipment supplier offering a "band new" two cylinder opposed Beaver motor in 1915. However, there is no way of determining if the "brand new" motor was indeed of recent manufacture or if it was new/old stock. According to the advertisement they offered several sizes of the opposed motor: 4-3/8"x4", 4-3/4"x4" and 5-1/8"x4-1/2". They also offered a four cylinder opposed. as well as a 6 cylinder vertical and a 4 cylinder vertical. Beaver was still advertising thier marine engines as late as 1925 - at that time it was an valve-in-head four cylinder with 4-3/4x6 bore/stroke. Very neat survivor!
  14. I believe Mercer used T-head and L-head Beaver motors
