Triggered by Tom's Diesel Shay contribution,
the MEW railcar of Bill Schopp came to my mind.

For those who don't know Bill Schopp, he was a modeler ("The Brass Butcher"),
who wrote for Model Railroad Craftsman beginning in the Fifties.

One of countless weird models he built,
was a Model Engineering Works gas mechanical Railcar,
which he placed on two PFM Shay trucks.

He later built a second one for a customer in Sweden,
this one still exits and was sold at Fleabay 15 years ago.

I happen to have both a MEW railcar, and two extra Shay trucks.

This weekend I built a new floor for the car,
and now I am in the progress of soldering appropriate bolsters to it. 

Next will have to find a suitable transfer gearbox.

Gearbox found... 
A tower drive, left over from a balky brass diesel.

Haven't got square tubing yet to extend the shafts,
so silicone tubes have to do for testing.

A screwdriver substitutes, for the gear-motor that is on order. 
With this arrangement, the motor should fit into the baggage compartment.

Any idea if there are (brass?) cardanic joints available? 

I found one and part of a second one, in my parts box ....
Would be nice to have complete prototypical drive shafts, revolving under the carbody. 

**IF** my eyes would be still up to the task, I would build them from brass .... it's not so hard to do,.
of course, I may substitute NWSL joints, and hide them under some sort of cover. 



....Ddisregard my message.... 

Have found plenty of those online, even locally. 
I am amazed what is available today! 

R.C. car racers and truck modelers, have many things we may utilize.

Hi Gerold  :wave:


A possible re-lettering to ... 'The Gerold Lumber Company' ?  :mex: 

:shocked:  ;)

It's good that you found the parts you need.
I am looking forward to seeing your 'genius' mechanicals !  :brill:


I have found some AMAZING mechanical parts in these ^^ categories on eBay.  :thumb:

The prices $$$ have been very affordable too.  :)


It can take a while looking ...  :time:

... but it's all there.  :P


:cool:


Si.

After many distractions,
(Buckhorn Powerhouse... Westside D&RGW side rod switcher... trolleys...  )
I felt it's time to do something with this mess.

Had once built a cardanic joint for an articulated trolley loco, but never installed it ...
So now I had to try this again. 

Had some leftover parts, but not enough for two complete joints.

Bent a piece of brass sheet to an U-shape,
then drilled straight through with a 0.9 mm drill.
Without breaking it!! 

Next, filed two grooves in a piece of 0.9 mm brass rod, cut it to two pieces,
laid the pieces with the grooves against each other, like logs on a log cabin. 
Soldered this together.

Bent the yokes - my homebuilt one, and the one I had found - apart,
put the spider between, bent them back together.

Presto - a cardanic joint from nothing!

It has one flaw...  it isn't centered.
There should be something (a blob of solder?) that keeps part in line. 
Next time I am wiser.


Here the makeshift installation.
Gearbox is pirated from an old Japanese diesel truck.

Got her running on jumper wires today. 


I am mighty proud about my built-from-junk U-joints and telescopic shafts... 
Doesn't look really pretty but it WORKS! 

Had to cut the long shaft and insert an plastic insulator,
as the drive shafts had different polarity ??
(how did this work on the donor Shay?) ???
 

Next will fabricate additional pickups.
 
Also consider to replace the gearhead motor with one with less reduction.
She really crawls very slowly.
It's 1:150 now. 


Here is a video of the first trial.

Some progress....  installed queenposts, truss rods, wire pickups... 

Soon will connect wires temporary to motor and do a test run on a DC track.


Wonder what "FR&ML Lines might be? 

"Feather River and Marysville" would fit my northern CA theme... one "L" too much.

Something different... very different.  :thumb:  :thumb:

It's coming together very well.
