Long story short, I'm attempting to "upgrade" the Atlas phase I GE B23-7 to a phase II. I've read the phase II units have the rear bolster located 12" closer to the rear pilot than the phase I units. Since I don't have access to a machining mill, I've been considering scratchbuilding a new frame with the bolster in the correct location. The new frame would also allow me to add more detail to better represent the prototype.
My question is, should I attempt this project using styrene or brass? The model will not be powered.

Ben, styrene is a good choice for this build. I like the way styrene works and a good selection of structural shapes are available from Plasti-struct and Evergreen. If you plan it out, it is possible to make it operational.

Thanks for the info Robert. Would you recommend cutting from a sheet or laminating strips?

For the basic foundation, work with the thickest that meets the correct dimension. I think the thickest styrene sheet is .040", but there may be others out there I am not aware of. As you add structural members, the finished frame will be quite strong. Dave Hussey did a scratch built frame for his F units which can give you a lot of ideas for your build. His postings are found when you search in pBase for his name.
