Routing the longerons
Such is progress.
Graham and I routed the lower longerons today. I borrowed Walter Ivey's 1/2 in shank plunge router (mine was 1/4 in) and used a 3/4 in wide bit purchased from Woodworkers Supply.
The depths of the routs varied from 1/8 in. deep behind the splice to 3/8 in deep at the tail post. In essence, the "I" section got thinner towards the rear.
Here's a sample of the longerons. Next step is to sand them, varnish tham, and add the copper end.
