CISX 500, a depressed centre flat car.

[JaBear]

Could it have been a good idea to put some weight into the central depressed structure?

Gidday Mark,( My Apologies Matt ) like most of us I don’t build things to fail but I always had concerns over how well the car would articulate over curves. So I opted to make the well platform light but strong knowing that I did have the option to add weight by adding a load.

Are you using small T-nuts to bolt the trucks?

My use of T nuts is explained in this instalment.
Using T nuts is probably overkill on my behalf but in my part of the woods the ability to purchase 2-56 screws without nuts of some type is nearly impossible, actually purchasing 2-56 screws can be slightly problematic at the best of times so I buy what’s available as long as they’re not at a gold plated price, thank goodness for the RC aeroplane builders. Coming from the waste not want not camp, and as I am concerned of being heavy handed (pawed) and stripping the threads out of the styrene, I put these nuts to use.

   

One of the spotting features of this car is the brake cylinders mounted on the buckeye trucks and as I had nothing suitable, and after several false starts and failures came up with this. Now I just have to complete the other seven.

   

I'm curious as to the size of those moulds.

Gidday Wayne, my knowledge of the steel industry is rudimentary at the best but as this car was designed to transport ingot moulds between two Carnegie-Illinois plants I presume that it is an ingot mould that’s depicted in this photo, from Tom Daspits site.

   

There’s another photo at this link, though I’m none the wiser as to why it needs to be so big....

And while I first posted this in the latest WPF here’s links to the car on its test runs.

Thanks for the kind comments and for looking,
