This version of my bow press uses the same frame of the original but replaces the cam clamp design with an inexpensive ($29 U.S.) worm drive from Harbor freight. I moved the crank handle over to the right side and substituted heavy braided nylon cord for the metal cable. With an adapter an unmounted prod can be strung or an unstrung one can be measured for a string. It takes around 12(40-1) turns of the handle to reach brace and with a worm drive the handle can be released anywhere with no backlash. The 2 pins are 1- 1/4” oak that go all the way thru the 4x4. This pic was taken in the kitchen because the lighting is more uniform.
