This question comes up frequently. In doing some research for ship models on my layout I came across this US Navy document. It is interesting. Note the lack of styrene as an acceptable material.  Also gives you an idea why government contracts are so expensive, note the documentation section.

I'm interested in learning how to make resin castings.  Could someone point me to an article or website that would help, or perhaps post a reply with tips, technique, etc. 

Also, has anyone had experience with benchtop injection molding?  How are results?  What kind of costs to get going?

Thanks

One of my future plans to to change the layout's theme to a Rock Island mainline and let the Mopac operate the small switching yard.  I just finished Blair Lines Gerald RI depot and placed it on the right of way to see how it looked with a freight running by.  l

Hi all-

I'm looking to start putting some building mock ups in place on my layout this weekend and wanted any suggestions on materials to use.  Ideally I'd like to keep the amount of interior bracing I have to do to a minimum so my thinking was that I would pick up some foamboard (the posterboard, not the insulation) or gator board but I'm open to any suggestions.

Thanks!
