- I envision this as one of those "try this at home" experiments.
- Not every undergrad has a miter saw, dowel rods (I would
- suspect the accuracy of this method due to the elasticity
- differences, and the deformation of the corners due to the
- softness of the wood), In his dorm room, to say nothing of
- thick steel rods, and the bandsaws to cut them accurately. With
- coins it is very easy to aquire the materials, and likewise to
- achieve reasonable accuracy, all in the comfort of ones
- dormroom. BTW, the shops at most universities are somewhat
- hesitent to allow students to use their equipment these
- days--prob. due to idiotic legal hassles over some student who
- cut his hand off, then sued the U.--just my $0.02 worth--AHB.
