territorialmillworks Posted May 5, 2013 Share Posted May 5, 2013 Building another hammer, this time a Kinyon Mark II. Most builds use 4X4 sq tubing for a 40# ram but others add weight for as much as an 80# ram. Seems that at some point there is a trade off between kinetic energy and speed. But my main concern is 'control'. I've upgraded this hammer with a 3/4" control valve and plumbing along with an additional 80 gal air tank. So I'm not concerned with starving this hammer.I'd appreciate any thoughts/suggestions.....Keith Quote Link to comment Share on other sites More sharing options...
macbruce Posted May 5, 2013 Share Posted May 5, 2013 Too much weight will make it sluggish, and could perhaps give it a heavier blow but when you're doing finishing work the slower speed is a pain when you want to wrap things up quickly. Too light of a ram and it will be too snappy but it will respond better to air pressure changes. A correct balance will give nice hard blows and snappiness with a noticeable difference in performance/bps between say 80 psi and 120psi.

SJS Posted May 10, 2013 Share Posted May 10, 2013 Another concern is anvil to tup ratio, if you don't have enough anvil to support a bigger ram, some of your increased energy from the bigger ram will be wasted bouncing the anvil and the hammer around. Good designs are balanced, look over at http://www.anvilfire.com/power/power-hammer-building.php the chambersburg anvil ratio chart is particularly useful. It is tempting to try to squeeze just a little more bang out of your budget and materials, but it is often disappointing, if not disastrous.
