Thanks

here is a chart
http://www.nuclead.com/leadbabbitt.html
Rotometals chart has #4 babbit as 1-2% Tin/ 12-14% antimony/84-86%Lead.
The chart above shows #4 completely different??
Its hard to say what it actually is composed of.
sent via hammer and chisel
need oversized powder funnels , PTX's or expanders ? just ask, I make 'em for most brands plus my own styles.
Notice this is HARDWARE babbitt...not grade 4 babbitt.
From Rotometals
Sold By the Pound
ie. 1 Quantity = 1 Pound
#4 Hardware Babbitt A Low Melting Point speed Babbitt consisting of approximately 87.5% Lead and 12.66% Antimony. Melt Temp Around 473 deg F
Hardware babbitt is a less specific alloy and is generally used for such things as hammer heads. The alloy you quote is grade 4 babbitt which does indeed require the quantities you quoted according to QQ-T-390 Specification Standards. The difference is that the first grade is a general non-specific alloy (with varying quantities of base metals) from back in the 1930s or before, while the latter is made to an industrial standard that is much newer. It does indeed get confusing.

Beware of man who types much, but says nothing.
Let me guess, the government was involved.

Thanks for ya'lls input. However, this lead is not hard enough to be used as a hammer from what I can tell. I can't scratch it with my fingernails but it gives when hitting something harder.
Most 'Lead Hammers' are for no mar and dead blow - not for driving nails. I have a few around here for when I want to coax someting into place and I can't push it.
Be surprised haw you can move something with a 2.5 or 5 lb hammer and not leave a mark.
