Well, I managed after two hours (two sawing and beer sessions), to use my crosscut handsaw to make a 3" slab:
Knowing that I'd never again want to spend that much quality time sawing one slab, I decided to make a raker blade bow saw:
It was a nice n quick project for a no-frills bow saw that can be easily broken down and stored - or displayed in its stark wooden beauty.
A few things I'd add with time are are:
- A hand guard or recessed handle for the lower hand grab
- An arch to the cross-bar for a little more clearance and other such nice curves
- Wing nuts
