Astro_Al Posted November 5, 2009 Share Posted November 5, 2009 Hi guys, slowly gathering bits for the hammer build. I want to have as solid a hit as possible, so I'm trying to go with as big a ram as realistically possible. The only downside to a bigger ram, as I see it, is more air requirement. Shout if I missed something. Standard cylinder bores seem to be 50mm, 63mm, 80mm and 100mm (and up). I have about 23 cfm of air to play with, more if its not 'free air delivery' and can recharge tank capacity between heats, which is realistic. I would consider adding more air if needed. Does anyone know how to equate these figures? Is 80mm bore asking too much of this air supply? Anyone built a hammer with an 80mm cylinder bore? My anvil will be around 1350 lbs, and the base plate about the same again, so I figure there is enough mass to absorb a fair size punch. Other things to look out for on the cylinder are: 1. Largest port size I can find. 2. Largest haft diameter I can find. ...Anything else? If I increase bore size, presumably I shouldn't play with the stroke, I need what I need, right? What would, in your experiences, be a good size ram? Cheers, Al. Quote Link to comment Share on other sites More sharing options...
