Post by Pitchy »

I seen a picture of one of these and it said it was a Leonardo da Vinci design not sure.
Got a terrible squeak to work out of it.

my version, should I live long enough, will have a hydraulic motor turning the crank.. or perhaps an overhead shaft and belt drive, eh?

well done Pitchy, that's actually a very useful tool

It could be modified to hit harder. Some chalk dust would fix that political sound.

I can see lots of uses for that, good way to put gas checks on bullets, flattening aluminum cans, declawing cats, heck you could even crack walnuts! Nice bit of engineering!

Well we got a x wife and a lonesome cat, it`s a terrible sound alright :lol:
I won`t be using it much and have no plans of improvements to the design just wanted to build a replica of the original.
Thanks for the replies guys. :)

Nice build but put a roller on the end of your cam follower. Makes me think of ex wife #2, thankfully deceased. Love it man.

Thanks fellers.

I didn`t have a side view picture of the cam when i built it now found one so had to re profile the cam so it would hammer fast.
Also added a bungy cord to give it more power, a spring would look better but didn`t have one at the moment.

That is a cool way to save wear and tear on your wrists. It may not hit real hard, but it looks like enough power for a lot of forging. My limited experience is that a fer hard blows with a big hammer and then a lot of lighter hits with a smaller hammer on good hot steel will get you what you want. Yes, the different steels may need more or less power. Ball bearing steel is hard to move. Good old OCS is pretty easy to work.

That's really neat Lenn -- I like it! Well done!

Found an image of Leonardo Da Vinci's "Cam Hammer" -- see below.

When will you build one of his weapons of war, or flying machines?! :wink:
