Hello Guys,

Ive been dabbeling with 1/8th scale or 1:6 scale or 7.5" gauge or "live steam" either way its big and heavy and you can ride on it! :thumb:

I joined a local club, and became a minature engineer, Aside from a real engineer, its pretty fun to roll along and listen to the clicky clacks of a minature railroad.


Ive been working on a design for  some sort of train set to build and call my own. Ive looked at  building critters, and mine trains, and  highspeed bullet trains.  and everything inbetween.  Ive looked into  the good ol Union Pacific M-10001 the original City of portland streamliner. but the complex curves on it have made me second guess my skills on my first large scale train set..  
I've looked around for ideas, talgo's and  such, then I thought  about a McKeen car.
but not just one Mortor car but 3 or 4,  with articulated connections between the cars each sharing a truck excpt lead and tail cars.

here is my design,  I figure O'l McKeen wanting to help put some boost into his failing company designed this train set..  the Ship on rails..  The "McKeenLiner"




So this is what im trying to build. the regular Mckeen car is on the bottom, thats the 55' version.  I took the image to MSpaint, did a little clip and paste, filled in some areas, an presto.  articulated trainset.. (on top)   Ive enlarged the engine to a sperate room since this thing will need a better engine than the previous motor cars  included  a  buffet coach and the tail car now is a parlor coach.  another car could be added for a pullman if needed seems Mr Mckeen left many options for  railroads to customize their new landships. RPO, Pullman, All coach, diner, buffet.  really tried to make a  go at it for his company.. :2t:

anyways, I will post pictures of my  progress, its still in the planning stages..
and im experimenting with fiberglass resin and pink foam, for the curved roof..

I have a pair of archbar trucks, totally the wrong type of design for passenger cars,
But Im working on a false front  design that will bolt to the truck and look like a proper motor car truck. Im on a limited budget. ( i know not a good scale if you dont have $$$ :bang: )

the cars will  have a steel tube frame, with cabnet grade plywood ribs and roof support. thinking about  thin metal for the car sides with linolium nails to rivit the sheet metal to the plywood ribbing.
I dont plan on having more than two persons on each car. as they only measure out a scale 40' or 60" long.

back to see how much foam the resin ate.. might need to make a white glue barrier to protect the foam

have fun with your latest project, don't have one? get to it then!

Hey all,
here is some work ive done on the "McKeenliner"  I cut the tubing for the frame.
I was hoping to have the tubing flapdisk sanded so I could weld it up, but alas I forgot the  special wrench to change the  disks on my angle grinder at home and being 140 miles from home, that wasn't a option. 
 I didnt get as much done as I wanted to on the project.  during the down time I made a scale model of my ummm model?   by using  styrene and  balsa I worked the frame and plywood  frames.  this actually helped me out. While building he  styrene and balsa model, I found a flaw in my plans that I have gone over and over on paper. hopefully I will have this welded up this next week and i can work on the bodies. 
The pink foam is just  the shape of the front and ends of the cars. still working on the powdered truck idea..
 I know right now it looks like a great lakes freighter :doh:
but soon it should look like a McKeen car, hopefully :shocked:

thats about 15' of train there, thinking about a 4th car to add on. all depends on my power truck, and how many I place in the consist


this is the balsa/styrene model of the lead car with the "windsplitting" technology
Now that Im back home and have the flap disk, i can sand off all that rust.
well back to work all! check back  later this week for updates!
cheers
Jason S.

Hey all,
The weather in the pacific NW has not been cooperating with me.  Rain, Snow, cold temps, and wind have put a  slow order in effect on the project :td:
I have to do my welding outside, so I don't burn down the  wood shop.
so today after many days of doodling on paper. I  whipped out a mock up of my car trucks. Some purists would say that's not anything like passenger car trucks. ehh I know, but alas i have no milling machine or metal lathe.


here is what i have come up with for the side frame  the middle part or upper frame will be made from 1/2" thick steel bar cut and welded, it will be sandwiched between  thinner sheet steel. the mock up was made from 1/2" MDF  and some 1/4" ply



here is the "insides"  this was a ruff cut to see it it would be feasible  and it is. just some minor tweaking here and there. the springs will be held in place with cups. the sides will be sandwiched  and connected by bolts.
planning 1/2" thick steel welded to the upper frame for the bolster, and thinner stock for the ends to keep everything square.

also looking for a good color of green for the car bodies. Im thinking Krylon Hosta Leaf green. I tried the Italian olive , but its too gray IMO.

more to come, if the weather will co-operate  :bang:

will post more when I can

cheers
Jason <----- :Crazy:

Howdy all,
Instead of the square blocks with 1.125" holes drilled, Im thinking round pipe cut 1/2" length with 1.125" ID  to hold the bearings  between the the sandwich, with the pipe welded to the lower sides.  Ive been having some "sticking" issues with the square parts, when I push down on one side of the truck it sticks sometimes.  I'm hoping the round pipe wont stick to the straight sides of the upper frame, yet still hold it in place and allow the upper and lower frame  to move freely.
time to get some pipe..

Ive done a practice run of my sheet steel-plywood-false rivet car body. just some scraps I had. laid out the sheet steel, drilled 1/16" holes through the metal an 3/4" ply.  then drove 16x5/8th linoleum nails into said holes, finished setting them with a nail setter.  then  cleaned up the mock up, and shot it with  Krylon Hosta Leaf Green.  when its all said and done these cars should be lettered for the Southern Pacific, with the Deluxe Gold Roman Script.

When I do my real car bodies I will layout lines and pre punch each hole with a awl mesured out straight and neat!



some of the nails set better, but i think that gives it a more real feel? i need a larger nail setter as this one is leaving marks on the head..




Krylon Hosta Leaf green, seems to cover nicely with out primer.  on the cars I will use Krylon primer of course still a good shade for SP green, might be too light..

anyways  having fun in the shop. cant wait for the weather to break!

cheers
Jason

Jason-

I have been following this, with interest, as back when we had a 7 1/4" outdoor line the last piece that I started to build was a Brill railbus. Still have some of the pieces, wheels frame and engine, I think, but it's been a long time.

Before you get too far into the drive design stage, give serious thought to powering at least 2 axles with whatever drive you propose, even if it means driving the "trail" truck rather than the front one. Perhaps you can come up with a chain and two different size sprockets to drive the front truck axles. The ratio does not have to be perfect, just close.

Been there, done that.

Herb

Thanks Herb,

Yeah, Im planing on axle mounted electric engines.
2 for sure, maybe one on each truck. I would like to have 4 total, but thats in do time.
I could have each car have its own motor, or put all the power up front which Im pretty sure since the lead car will be the heaviest with batteries, engineer, so forth.
im going to breakdown and buy a one powered axle from plumcove studios just so i have something to work with. for designing the trucks, and know where to drill the mounting holes.
well keep you all posted
Cheers
Jason

here I laid out "rivets" in a more scaled fashion.
should look great along the car body.

painted  Hosta leaf green krylon rattle can.  new rivets on left, first batch on right..
this is 22 gauge weldable metal steel sheeting (1/32" thick) laid on 3/4" cabinet grade plywood,  I might go with 16 gauge (1/16" thick for the sides, but I'm liking  how this is turning out.. final  carbody will be painted on both sides to seal the steel, and the ply coated with primer sealer  before the riveting the metal to the wood, the under frame will be coated with fiberglass resin to discurage  rotting, the inside of the cars where the  riders will go will painted or coated  with a spray black truck bed liner seal it up and provide traction when getting on and off said cars.
still raining here in the PacNW.. so no welding..
Guess more little projects to do.!


cheers
Jason
