I've been getting a lot of requests to do a completely centershot bow. The snakey recurve is centershot, but it is not far enough past center to accommodate most captive rests or to be ambidextrous. So I'm attempting to build a primitive-styled fully centershot bow.
The bow itself is based off of some examples of pellet or stone bows from Southeast Asia that were used much like modern slingshots. A wide space between limbs and clearance over the handle allow pellets to fly through the bow without hitting the bow or bow hand. If used to shoot arrows, they are under minimal effect of Archer's Paradox as the bow is fully centershot.
The bow is made of two 1/2" schedule 40 PVC pipes tied together at the tips and then tied to a handle structure made of two 1/2" pipes and a 3/4" pipe. I tied the pipes with cotton cord, which is strong enough for this low weight bow. The bow also has a bow quiver of sorts built in that holds 4 arrows, both target/field points and broadheads.
This was just an experiment for me, so it came out with a shorter draw than expected. The stiff handle section was much stiffer than I though it would be and caused the bow to stack a lot past 26 inches. All in all it's a good bow, 32 pounds at 26 inches. The next step is to build a heavier bow with a longer draw!
Thanks for watching and enjoy!

The heating trough is made of a non-conductive base like cardboard or wood shaped like a gutter or round tube, covered in a reflective material like aluminum foil or flashing.
