Save yourself the time, cost of set up, dangers of cutting many thin scale boards, cost of a good blade to get decent sticks, and on and on . . . Many reasons why it is just cheaper, more consistent, and better to just buy what you need. I highly recommend Balsa or Basswood.
Several years ago I wanted to build historically accurate scale houses, not doll houses per se', but smaller desk top homes with scale dimensional boards that are not just the today's standard 2 x 4's, 6's, 8's, 10's, and
12's. I had to cut my own to get what I wanted and I have learned considerably since then.
If you need help with your project, I can help you and/or point you in a good direction. If you need the supplies, I can help you there also. Working with educators to build houses, bridges and towers for the Science Olympiad competitions, and in general working with wood in the class is what I do. My prices are cost effective for teachers and students, all the wood is in bundle quantities and well taken care of.
If you only need enough for a few students and are building very simple and limited structures of only a few walls, any hobby or craft store will probably have enough in stock for you? Maybe, they are limited on quantities and condition varies. And most of all, you will need more wood than generally comes to mind when you think about building a little scale house! History has taught me that but I live for physics, engineering, automata's, and math.
You can respond directly if you need any further help and if you need the wood, go to my site located below. Don't worry about the site seal. Trying to renew after changing servers has proven to be a real headache and long process.
Have fun with the process, Patrick
