      The "little short line" needed some power....

      As you know, I have another thread going about the "little short line" I'm building to go around our home (for the grandkids, of course :)). Well the new railroad needed some added power to do some "switching chores". This Super Husky (available from Eaton Custom Engineering in Castle Rock, WA.) fits the bill. Only weighs 150 pounds ready to run and is made of 6061 T6 aluminum plate. Has two small automotive batteries (Group 26) and is powered by a single 500 watt, 24 volt motor through chain drive to all four wheels. This engine can be lifted by two people and put in the back of a SUV with room to spare. Completely wireless controlled with Phoenix Sound exactly the same way we run our garden railroads. Pretty nice package and a strong puller. There is a video on the website that shows this single engine pulling 11, 1-1/2 scale gondolas. Very impressive for a loco this small. 

      Today I picked up the aluminum material from a friend who got it for me, to begin the chassis build. I returned the pieces I needed to be sawed to my friend this afternoon at the Los Angeles Live Steamers facility. Once they are rough sawed, I can start to mill the pockets for the journals and fasten the pieces together with bolts and nuts and 1 X 1 X .125 thick aluminum angle stock.

      To get a comparison of size of this engine, that's a 36 inch square head blade laying on top of the stock. 1/4 inch thick aluminum.

       

      In the back of the car, ready to take to LALS and turn over to my friend to do the saw cutting.

       

      A couple of photos of the finished engine. When completed, it will look exactly like the old MDC model in "G" scale. Remember the Lil' Hustler?

      Very cool. 

       

      Certainly cooler than my Athern with dual rubber band drive.

      Wow that is cool.  Would love to do that around my property.

      What kind of suspensions do these big things have?

      About  a 3/4 inch diameter coil spring, with .090 wire, over each journal box.

      Okay. I was wondering whether that was a detail or functional.

      Forrest,

      When you get to engines of this size, everything works. The springs actually have to function :)  (along with all the other mechanical items). The axles have 1.125 diameter ball bearings on each end and self-aligning flange ball bearing on the idler shaft under the chassis. All four wheels are change driven.

      Really liking this build.  I'm sitting here taking notes.  Keep up the good work!

      Gary,

      That is really sweet!  I have always loved that little engine in various scales through the years and it is just perfect for your "Grand children's" railroad.

       

      You didn't really say but I assume you are building it from "kit form" ?

       

      Thanks for sharing

      Rick

      Actually Rick, I'm "scratch-building" this engine :). I'm buying the materials (aluminum plate 1/4 inch thick). I had it sheared to finish size (plus/minus .005......cost a little more this way, but avoided the task of milling to size. When my buddy finishes the saw cutting, I will "pin" the two side plates together and set them up on the mill and machine the journal box areas. Found some 2X2 6061 T6 aluminum block in the shop and will make the journals from that stock. Cut the slots in the blocks so they will slide in the side plates and bore the 1.125 pockets for the roller bearings. Axles are already made. Turned those and the wheels on my lathe. I had some wheel castings laying around the shop. 

      I will have to order the chain sprockets and flange bearings for the idler shaft from McMaster-Carr. Everything is pretty much "off the shelf". I have to get a quote from the local sheet metal shop for the aluminum for the cab. He will also do the bending and cut the doors and windows out. It's a pretty simple engine to build actually. The single motor is a 500 watt, 24 volt motor.

      Scratch built, even cooler!!!

      Yea,  the cab shapes look like a pretty straight forward fabrication: brake, slip rolls and nibbler.

      I assume the axle bearings are press fit in the journal blocks??

      Yes the bearing pockets will be a couple of tenths smaller than the bearings. Makes a real easy press fit into the aluminum. 

      The funny thing about this build is that Rich Eaton (owner of Eaton Custom Engineering in Castle Rock, WA) builds these RTR or they can be purchased in "kit form" in "modules". When I purchased my rail bender from him, that's when I noticed this little engine. RTR they are about $3000, painted and delivered. You save about $500 when you purchase the kit. I inquired about a kit and he told me with my experience, he would just tell me what materials to buy, the sprockets I needed (pitch, diameter, etc.) and he even sent me a couple of cad drawings :)! So he is actually helping me to build this thing with tips and suggestions and a couple of drawings. I'm getting this engine for less than a 1/3 of the cost bhy doing the work and designing myself. Pretty nice guy to deal with. He's also an Air Force veteran :) and flies helicopters.

      Also this engine is wireless controlled and has Phoenix Sound. I don't even have to ride this engine to run it. I can sit on a bench at the club and "watch it go around the club track". The range is about 200 feet! He has a couple of Youtube videos showing it doing that! Very impressive little engine!

      In my other post on building a turnout, the switch stand shown is one he GAVE me. The guy is pretty cool!

      Well being an Air Force Vet he has no other option but to be "pretty cool"

      What is also cool is the Phoenix sound and didn't you say it was Airwire control?  Just like running our 1:20 stuff except you can wander over and go for a ride.

      The Grand Kids will love this.  Do they know your building it for them?
