Large Scale Central

Steam Railcar (LGB parts)

Modeling
#1

Just completed. Minimum 10-foot diameter curves, unfortunately.

#2

Needs a hinge.

Nice bash Tim. Is the rear truck fixed in place? If it’s not I would think you would be able to get around tighter curves. how about a slotted bolster for a little side-to-side play for tight curves?

#4

I like it!
Hmmmmmmm…
I might add something like that to the project list. :slight_smile:

John,
the rear truck is on a slotted pivot and has approximately 1.25" of sideways travel, with a radius arm approximately 2.5 inches in length. On ten-foot curves the truck is already outside the extremity of the body. Ten foot diameter is the very minimum allowable.

#6

OK - It’s a lot longer than I thought :slight_smile:

#7

Wow, now THATS cool. I may have to do something like that.

#8

Bob, underside of car with trailing truck at full deflection. This is ten-foot diameter minimum. To enable less than ten-foot would entail more engineering. At ten-foot the truck is at the extremity of the coach body. Truck is pivotted and runs in a slotted curved plate. In essence, not a very practical modification, but it looks nice.

Not to mention it does look Kewl!!..:wink:

great choice of colors!

Great make up of a trailing truck. How many of those have we cut up?

#12

Nice work Tim. Are those Aristocraft Ball Bearing wheels? If so, how do you like them?

#13

Dan,
yes, they are, taken from a snow plow. I knew that I was never going to need ball-bearing wheels on the car and so scavenged them for this project and another. They work very well indeed, tracking very true and pick up power as well as any other current collection method. I prefer them over ‘the other brand of ball-bearing power pickup’ (German quality, Made in China) as they have more weight and allow the trailing truck to track more reliably.
