Do the light outer limbs make up for the extra stress and bend? Some people say the levers give extra movement at the tips, but I don't see how they can give more movement than the same length of limb that actually bends a bit.
Anyhow having finished the last bow and getting ready to lay some flooring next weekend I wanted a quick fun project.
One advantage of having accumulated loads of odds and ends of timber over the years is that I can usually find something for a quick try out experiment. I have some cherry that was cut from standing almost dead a good few years back.(2010)
There was bug damage in the outer wood but it had been planked up to a suitable size.
because of the bug damage I laid the bow out with the central pith on the back of the bow (see middle pic). Now that and the fact that Cherry can be a bit brittle made me decide to back it,...but with what?
Ash, Hickory, Hazel, Rawhide are all candidates, but I found a piece of Yew that I'd sawn off a stave that had very thick sapwood. It still had the bark on and was probably too short for a longbow.
Perfect, both the Yew and the Cherry work easily and quickly with with drawknife and spokeshave. They are both very light woods and hopefully well matched. I do have Bamboo, but felt that was probably much to strong in tension for the Cherry.
The cherry was first cut to shape on the bandsaw. I had it all done in about an hour or so and I've got it glued up this afternoon. It was quiet at work, so I took the afternoon off... I can't abide enforced idleness and the components I'd ordered hadn't been delivered yet.
I strapped it up and then tied it down to a length of 2x2 back side down with a small block under the grip just to hold it straight /slightly reflexed while gluing. (The Cherry had a slight deflex as it was worked down).
The bow may well explode as I'm planning on pushing it hard to see how it performs. I'm aiming for 40-50# at about 24" draw. I'm going for a short draw to get a more aerodynamic arrow length for flight shooting. It should be interesting to see what it does.
