Is there such a thing as...

bass or balsa wood comes in strips of various widths. Anyone here with math skills (I don't have them) could tell you of a

Craig.

Lots of such sources, mostly in bass wood. For 1:12 scale you can check out various doll-house suppliers. They have everything including siding, shingles, etc. For 1:48 and 1:96 there is O scale and HO scale model train stuff. Also a wide variety of preformed stuff. Another source is a supplier for people who build architectural models. For scale plywood you can find different kinds of high-density plywood in thicknesses ranging from

I hate to be pedantic here [1] but... O and HO refer to the *gauge* rather than *scale*. O gauge relates to a scale off 7mm/ft - effectively 1/43rd. HO relates to a scale of 3.5mm/ft - effectively 1/87th. The nearest model railway scale to 1/72nd is 4mm/ft (1/76th), which has three seperate gauges, OO, EM and P4. *Long* story - don't ask! :-)

For 4mm scale,

Most decent crafts & hobby stores/shops will have this in either balsa or a couple others. If you are not sure what scale you want to use, check with the hobby shop and see what size their stuff is that would equate to a scale you want to use. Michaels, Hobby Lobby and most local mom & pop hobby shops should have a real good selection. John

bzzt. Just like in plastic modeling, scale is simply the proportion of a model in relationship to the real thing.

Just like in real life, gauge refers to the distance between rails.

Combining the two will get you something like HOn3 which represents HO scale, narrow gauge rails using 3 foot wide rails.

Micro Mark used to sell a wide selection of sheet and plywoods for hobby purposes.

Model railroad supply places have a lot of this in 1:87 and 1:48 scale. Dollhouse/miniatures suppliers have it in 1:24 and 1:12 scale.

Walthers, a model RR supply place, has 1:24 (G-scale) plastic embossed sheets of brick and concrete block.
