    • Gary,

      Thanks for sharing.  That is so cool! Technology seems to be changing everything.

    • Well, a few months have gone by and no updates to this build for a while. We have been busy getting the remaining six cabs riveted. In the meantime, I was doing some research and designing the model louvered panel doors that were installed on the end hoods of these 1600 series locomotives. We were trying to decide if we wanted to have louvered panels made. These louvers were the result of that idea. These were actual louvers, but not to scale. AND we add to attach each panel together to make one large panel door. Bad idea....back to the drawing board and the computer.

       

      Then last May, I saw a company advertisement on Backyard Railroading Facebook site. A small foundry near Kent, Ohio specializing in unusual detail items for 1" and 1-1/2" scale detail castings and 3D printing work. I contacted the owner of Fair Weather Foundry and asked if he was interested in a project. He was and he said to send a photo of the actual louvered doors on a prototype P.E. electric engine and he would see what he could do. I have quite a few photos of the #1624 P.E. freight motor at Orange Empire Trolley Museum here in So. California. I found a photo and sent it off to him.

      This is the photo and the closeup of the louvered doors.

      AND the closeup..........

       

      I had my answer overnight! He took the photograph and embedded it in AutoDesk Fusion 360 software. I think many of us use this software to do 3D printing here on LSC. The photos below show how the photo became an actual mold for a sand casting in aluminum!

       

      From this Fusion 360 drawing, the foundry 3D printed the master model for the sand mold casting. Took one hour to "print" the master. He did some finish work to get rid of the tool marks and pressed the master into the sand.

       

      These are the results and the finish aluminjum castings. The crazy thing is that the technology was so fluid throughout the process. No charge to print the mold and $15 each for the castings!

      We have to do some milling around the raised area of the casting so it will fit the existing opening in our hoods.

      This was the first casting and hjad some blow holes and fall away of the sand. He sent this along for checking dimensions. All in all, it was a great experiment. It opens up a whole new world in making EXACT castings from any photograph!

      Dan is building a few ore cars in 3-3/4 scale to be used as riding cars for passengers. All steel and very heavy. We wanted heavy cars to really test the strength of this engine. I'll have to find out what the tractive force is for this loco "). It's very strong, I know that.

      I hope that weight doesn't over test your bridges!

       

      I won't run it on my home RR. Too big and not enough side clearance. The cab is around 24 inches WIDE! The bridges at LALS are rated for the heaviest steam engines built in the ride-on scales. The heaviest engines now are the #24 Sandy River 2-6-2  two-footers in 3-3/4 inch scale! These are massive engines and are nearing the limit of what can be run safely on 7-1/2 inch gauge track, even steel rail! These engines are around 2500 to 2800 pounds dry!

      I'm jealous.

      Don't be......this engine is a handful. Weighs over 600 pounds and handles like a full size steam engine. Has a very nice "bark" from the stack when pulling the 3-1/2% grade through the South Tunnel on the LALS club RR.

    • I just received a photo of our 3-3/4 inch scale (on 7-1/2 inch gauge track), newly painted and lettered for her prototype sister. Came out very nice. Painted by the owner Dan O'Brien and lettered by a sign painter who works for Walt Disney Studios. AND yes, that is gold leaf outlining the lettering :)!

    • A bit more progress, to hot to work for very long outdoors.  I pulled up and relaid the landscape edge pavers, reset two path lights and wired them back into the circuit and pulled some weeds up along the deck that you cannot see in this pic.  Planning a board walk up to and across the future track, then up to a square rock or brick paver area around the fire pit.  I will fill in the new areas with river rock once I kill off the weeds and grass(mostly weeds).  Our front yard looks great, but the back has been neglected for several years.  There used to be a tree where the fire pit is, lightning got it a few years before we inherited the house.  So there are roots galore making setting brick walks down in the ground a real bitch.  So I am thinking boardwalk to a river rock area around the fire pit.  I have a holly bush that will get relocated near the crossing signal once it cools down some, way to hot to be digging.     Mike the Aspie

    • That would I would do Tom, get a chassis and build a body for it, then go play on the club tracks.  Thankfully we have our own house with a fenced back yard that will be my playground so to speak.   I really really want a MTC G12 streamliner like I rode in as a kid.  The gentleman that I got the signal from has one but I was afraid to ask the price as all the ones I looked at are north of 12-15 thousand dollers in nice running shape.  Came with a loop of 12" gauge track that would fit perfect in our back yard.   Just way beyond budget for me for several more years.

    • Sharp looking loco Mike,

           Our lot in our new FL home is small and no "outdoor train sets" are allowed so I'll have a screen room built to house an oval of Ga 1 track.  I've been thinking about a plum cove electric chassis for which I will build a body.  Fred Gandolfi took me for rides around the Big Boots track with both his electric and live steam beam engine.  It's quite a scenic place, running through the woods, claiming to be Florida's largest 7.5" gauge railroad and just over 20 mi from our home.

    • The loop of track will go right behind the signal.  I am planning a walking path from the deck to the fire pit area, boardwalk up to a point then a paver stone area around the fire pit itself.  The signal is powered by 110 ac right now, but that just feeds an power 150wt power supply that puts out 12 vdc thru a bridge rectifier to drive the relays bell and lights.  So 12vt dc could also be tapped in as well.  Looking for ideas to trigger the signal when the train passes thru the future crossing path.

    • link to video of the signal flashing, both without and with the bell turned on.

    • Tom, I am getting burnt out on G scale.  Anything else I desire, which is mostly live steam, is in the same price range as ride on scale stuff.  Track, when priced per foot at brand new prices is nearly the same between G and 7.5 gauge.  I am now hunting for some good second hand rail in the local area as with G or 7.5, new track is to salty for me while I am still paying for this engine for the next 3 years.  We had to get a small loan from the credit union to purchase it.       Mike the Aspie

    • I got an older Railroad Supply Co GE 25 tonner, Kohler 4hp gas powered with Eaton hydrostatic tranmission to chain drive to both axles thru a gear box.  Nicely painted in the CB&Q Everywhere West paint scheme.  LED headlight and LED Prime beacon on the roof.    Pic is from the club in OK that I bought it from.

    • What locomotive did you buy?

      I'm considering 7.5" gauge.... like I need another hobby.

    • My wife and I went down to Greenwood, IN to pick this up last night.  I sold my full scale crossing signal as its way to large(nearly 14 foot tall with the bell) and needs a deep concrete foundation to keep it upright.   I had a wanted post on the discover live steam website, same sight we found our locomotive on, for one of these old MTC(Miniature Train Company) crossing signals.  A gentleman messaged me that he had two of them that were newer reproductions that he was selling. It is made from cast alum instead of iron, so I can carry it around with 1 hand.  Flashes and rings just like the old ones but with solid state controls instead of a motor and contact strips.  Uses GE red sealed beam PAR36 lamps for the light heads.  I am going to make a portable base that loops like concrete so I can bring it out of the weather or take it to a show.  We are now looking for some used rail locally so we can start laying the track around our small back yard.    Mike the Aspie.

    • Hey Rooster, Excellent research!

      .

      Yes, on the selective compression.  Basically modeling two of the switching yards.  Cherokee Street Yard to the south of the complex and parts of the River Yard, between the engine house and the Mississippi River flood wall.  There will be a number of designated interchange tracks and industry tracks for the American Car Foundry, Terminal Railroad's Carroll Street Yard, Dorcas Street for the Manufacturers Railroad and industries on Second Street, Brewery Trackage and approach to both the MacArthur Bridge going to Gateway Yard across the river and Mopac's Lesperance Street Yard.

      ,

      I spent a lot of time in this area in the 1980's watching the switching and waiting for access to the US Army Corps of Engineers Base at the foot of Arsenal Street, which is now US Coast Guard Base St. Louis (first line of defense, which ever side falls off)
