jimbob Posted February 8, 2009 Share Posted February 8, 2009 I have a good bit of torsion bar steel, I want to make some hammers. the steel is 1 1/4 in dia. now say I want a hammer head 1 3/4 dia. and 4 1/2 " long, so how do I figure out how much extra I need to cut to bump it up to 1 3/4" ?

rthibeau Posted February 8, 2009 Share Posted February 8, 2009 ABE VOLUME CALCULATORS, CYLINDER That calculator says 8.83 inches of 1.25 dia would yield 4.5 inches of 1.75 dia. I'd cut it at 9" and see what happens. Quote Link to comment Share on other sites More sharing options...
