Just for the record, there are at least two philosophies regarding the construction of side escapement planes. They differ dramatically. I have built planes using both of the methods and can tell you they both work just fine. Larry Williams advocates the traditional methods of design and construction while Tod Herrli is much more modern in his approach. I would suggest that if you are going to build any quantity of side escapement planes that you invest in both of their DVD's and check out the opportunities for differences yourself.
