This pic might answer Bobby's query about ability of side bars to rotate to track undulation. The vertical links have slots in the bottom for this, though why they are so long is not clear, I slotted the bolster plank (top pivots) giving enough flexibility for about 5mm lift on any one wheel.

Then finally epoxied in some dummy axleboxes  made from plastic. I milled some stock castings, hence the snowstorm on the mill table.

Peter,
 
Those trucks came out nice. I must have misunderstood the earlier post as I thought you were still sorting out some issues. It is a very interesting design.
 
Now, how much 1 1/2" square cold-rolled solid bar did you need? LOL

I was! but my brain was hurting, so I put them aside and did other projects that didn't hurt as much. John's post got me thinking again, so out they came again
Meanwhile the country coach is all but finished, in time for a exhibition on Sunday,   (No4 cow car got some attention too, and the Andrews trucks for a future project, arrived from ebay US)
BTW Love your new build, keep it coming. Pete

Don:  I couldn't agree more...awesome combination!  Love 10 wheelers, cabooses and passenger cars in one train.

Show time for the cattle train. 4 cow cars for the first time (last one part finished to show construction methods).   Big pull for a ten wheeler on those grades but it came through without missing a beat, or running out of steam or fire or traction  (touch and go on the traction part!)

And on to the next project, the drovers car. ( for 3 cowboys, their horses and dogs)  Also used to transport valuable cows to shows around the state.  This is my first 4 wheel wagon, and a whole new set of skills to learn.
 
I'm using some recently released diecast wheels which are real pretty, but not suitable for ride-on or for working brakes.
 
A gift out of the blue, of enough W irons, cast iron axleboxes, wheels and couplings for 5 wagons, from a respected engineer who changed his mind.
Outstanding generosity, and very humbling.  Some of the bits on the little table.
Pete
 
 
btw  Welcome back Pockets......now build something

Moose, the wheels come from here and they are quite cheap
http://www.dncsystems.dynalias.com/minirail/
They are very strong, quite OK for non-riding cars, it's just that the alloy will wear if heavily loaded (i.e. grandma and the ankle biters) and will gall with most brake shoes.   Soooooo...On the gandy would be dandy

Underframe as far as my research allows. (How do those steps mount ) So on to some bodywork. Plywood floor and ends, but sides and cladding to be aluminium. Here's my excuse of a drawing, and the first ally panel marked ready to be cut out for windows/louvres.

And the first mock up. Strong shelves for battery and compressor with space in the middle for water tank. Ally will have detail fixed on, but sheet should make it strong
Moose. I need cosmetic brakes so I thought I'd make the shoes from wood. Then I figured they could maybe  work as hardwood wouldn't gall (maybe)

Pete, we used oak shoes on our cars and they worked fine.

Pete, thanks for the welcome. Trying to get the shop in some sort of order and then it's back to work (play?) on Moosey's Model T.
 
Your projects are true works of art. I wish we were close enough for me to apprentice under you.

Wooden brake blocks it is then. Thanks Tom
The louver panels had me worried. There's 12 of them requiring well over a hundred slots. If not done accurately, it would look awful.
The obvious path for cutting angled slots would be 1/16 slot drill on the mill with manual indexing, but I didn't have enough supports, nor is the horizontal (Y axis) good enough for multi repeats. Sooo....
Remove toolpost on lathe cross slide. Mount pillar drill vice using some 50 x 10 packers. Drill and tap 2 12mm holes in cross slide ( scary doing that to a brand new megadollar machine).  Remove slitting sawblade from its arbor and make a longer, stronger arbor from 1 1/2" bar,  and Bob's your uncle, angle slot mass production
Using the digital readout means even a plodder like me can make nice slots.
 
See what you can do now with a lathe, Moose.   Model T parts maybe
Pete

Still too hot to build track, so some progress on the horse car. One side takes shape and louvers don't look too bad.
