I decided to finally build a infill plane. First I made a mock-up, to see if it will be usable. Here's the first version.
Reading Derek Cohen's writeup about building the Brese Small Smoother kit got me wondering about shavings clogging in the throat. So for the second version, I moved the back infill backwards, and put a radius on the back of the front infill. This increases throat size.
Right now this is probably what I'm gonna make. To follow the entire thread, go here.
