Let's design a hammer for Larry! - The KAIJU

[Larry L]

So i guess I am going to have to build two hammers.... I really want to build a more normal hammer and might end up doing it first... something in the 150 pound range... I think I am going to wait till I understand a bit more about the linkage system I got on order and see where that takes me...

I got plenty of steel to build several...

I might have to get a hold of Jess and see what he thinks about modifying the Chambersberg

Multiple hammers mean less die changes

How hard is it to build a drop hammer?
(Something like a cecostamp?)

What if you used, say, three polished rods (like for a hydraulic press), and an air cylinder that functions solely to break the (very very heavy) ram?

Of course you have some mechanism to haul the ram up.

I think to be very useful it has to be quite heavy and have enough travel to hit quite hard, so as to do the task in 1 blow. Otherwise what advantage would it have over the large powerful air hammers?

You might consider a board drop hammer; heavy upper die in guides, raised with a pair of motor driven pinch rollers dropping to a fixed anvil - a simple as it get. The blow is govered by the height of the drop. A maple palnk is the typical board used to make a board drop hammer.
