January 3, 20206 yr Was going to build a electric/cam powered hammer but changed my mind. Building a copy of this machine. So far I have a 16lb. sledge hammer head and a homemade flywheel.
January 4, 20206 yr I hope you mean a homemade pulley. I don't see where a flywheel is needed for that type of "Oliver" hammer. Hard to tell from the photo, what lifts the hammer back up? Just belt tension? If so I see that as potentially difficult to maintain.
January 4, 20206 yr The two return springs are located at the end of the linkage that goes around the pulley. Belt tension operates the pulley.
January 4, 20206 yr Connecting the treadle directly to the hammer shaft with a return spring/s at the end of the hammer opposite of the head would be simpler to build but if you're wanting to reproduce that exact configuration then keep us posted. Pnut
