buickmarti Posted January 3, 2020 Share Posted January 3, 2020 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. Quote Link to comment Share on other sites More sharing options...
Latticino Posted January 4, 2020 Share Posted January 4, 2020 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.

Glenn Posted January 4, 2020 Share Posted January 4, 2020 The two return springs are located at the end of the linkage that goes around the pulley. Belt tension operates the pulley. Quote Link to comment Share on other sites More sharing options...
pnut Posted January 4, 2020 Share Posted January 4, 2020 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.

buickmarti Posted July 25, 2020 Author Share Posted July 25, 2020 Finally got around to welding the base for the hammer. Quote Link to comment Share on other sites More sharing options...
