I need a platform so goods and materials can be transferred between regular and narrow gauge trains. Regular gauge is N scale and narrow gauge is Nn3 I started by making the roof trusses and they are GASP!!! made of wood, not cardboard. I got a new Ryobi bandsaw that was on sale at HD. It does a fantastic job of cutting wood in sizes I need. The trusses are made out of 9inch by 12 inch posts, 6 inch by 9 inch support and 2 inch by 10 inch cross beams. The 2 inch thick pine is so thin light shines through it just like paper. This saw will come in handy for many projects.
