buickmarti Posted September 28, 2020 Share Posted September 28, 2020 Saw a picture on the net of a hammer made from a rear Differential from a car. Guy up the road had a junk one out of a 73 roadrunner and I figure why not start collecting parts. One on the net uses shock I am thinking coil-over shocks or maybe struts from a car (both can be bought used cheaply). Took 11" out of each side.

ThomasPowers Posted September 28, 2020 Share Posted September 28, 2020 The build Jock did using shocks was a bit of a disappointment IIRC. Quote Link to comment Share on other sites More sharing options...
JHCC Posted September 28, 2020 Share Posted September 28, 2020 As I remember, the shock absorbers did their job a little too well: rather than transferring the shock from the mechanism to the workpiece, it absorbed it. Who'da see that one coming? On the other hand, I'm still intrigued by the idea of using a differential mechanism with a brake on one wheel to transfer power to the one driving the hammer. Keep us posted. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 28, 2020 Share Posted September 28, 2020 I'd think you could drive a dupont linkage using it. Quote Link to comment Share on other sites More sharing options...
jason0012 Posted September 30, 2020 Share Posted September 30, 2020 I believe Jock redesigned it with springs. Quote Link to comment Share on other sites More sharing options...
