unnecessarily large bow saw

A friend of a friend had a couple trees come down in a storm recently. I picked up a station wagon’s load of branches I could cut with a hatchet. To go back for the larger trunks I made a bow saw. I bought a 36” raker tooth blade made by Bahco and found some large bow saw pictures online. The crossed stretcher design should help the frame rails say rigid; at least that’s my thinking.

A couple splitting wedges and a big hammer yielded quarters from the ~10” diameter branches. I did most of the shaping on a lathe. The stretchers got a 1/2 diameter cutout in the center where they would intersect, and 3/4”x 1 1/2” tenons with tapered ends. The rails got flattened to create a roughly oval cross section and over sized mortises. I used a 3/16” drill bit to pass a coping saw blade through for cutting the bow saw blade kerfs. The green wood started splitting right away so I dipped the ends in some black polyurethane I had laying around.

The blade cuts well but the frame is entirely too heavy. I plan on going back over it with a spoke shave to trim down the ends of the rails and the transitions on the stretchers. Hopefully it doesn’t split/warp to death as the wood dries.
