[edit] Untitled
Need to add something on hammers with moving parts like jack-hammers.
Better to just make a link to the page War Hammer than add a whole section just for a sentence (Dec 2010)

[edit] Hammers are used to perform measurements?
The second sentence in the article is now "Hammers are also used to perform measurements." While this might well be true, it's hardly deserving of mention before other much more common uses of hammers (driving and pulling nails, shaping and bending metals, breaking up concrete, etc., etc.) Perhaps this measurement use could be moved further down in the article. Cheers, Madmagic 07:13, 8 November 2005 (UTC)
- Agreed, but removed it completely as the same argument can be used for any tool. It's hardly noteworthy Graibeard 07:49, 8 November 2005 (UTC)
Hi:
I think it refers to, say, the number of force needed to drive an object much like a torque wrench.
[edit] make me a timeline
make me 1 of the hammer pls

If you want, I have just uploaded a nice picture of a hammer (public domain) that I took. Hope this helps. Leif902 23:16, 5 March 2007 (UTC)
[edit] Basic hammer physics
This makes no sense: "High tech titanium heads are lighter and allow for longer handles, thus increasing velocity and delivering more energy with less arm fatigue than that of a steel head hammer of the same weight."
If the titanium hammer is lighter than the steel one, how can you compare its blows with those of a steel hammer of the same weight? Skyrocket654 03:11, 6 October 2007 (UTC)
By increasing the head's volume - since titanium has a lower density, you will need a larger head to have a head with the same mass as a given steel head.
However, I would like to concur with Skyrocket that the physics entry needs work; for one thing, it is patently false that the physics of swinging a hammer are as simple as kinetic energy in head = muscle force * arc length, as a human arm is a class three lever, meaning that the force at the hammer head may be different than the muscle force. If we let the torso be the fulcrum for simplicity, a human swinging a hammer with an outstretched arm of length "l" and muscle force "f" will have a hammerhead force of fl/h, where h is the handle length. Further, there is more to this than how much energy is stored in the head; as the entry does note, it's very important how far the head travels before stopping, and while I'm no physicist, it seems clear that since momentum is mass times velocity, and stopping something represents a change in momentum where typically you can't change the mass, the more mass the head has, the less velocity (for the same momentum), implying that a high mass head is "easier" to stop - i.e. it should travel less distance before stopping, *increasing* the functional force delivered. Also, recoil is covered under the handle section, but as noted there, the head material matters - apparently steel is 9 times more elastic than titanium, according to the entry - and I would think that belonged under the head section. Lastly, surely the surface area of the hammer matters a lot? The drag on the hammer head will increase with the square of the velocity, so you'll want to put some effort into making the head aerodynamic, and of course pressure matters - there's more to that pin having a wide head than making it easier to hit, you know.
Could someone who knows what they're talking about (i.e. not me) take a look, please? —Preceding unsigned comment added by 71.234.27.153 (talk) 02:49, 28 October 2007 (UTC)
[edit] Removal of Empirix's Hammers from Symbolic Hammers
Dear Wizard191. I can appreciate that there may be some justifiable reason for removing entries in a particular article, but it would be really helpful (not to mention courteous) to at least leave the previous editor/contributor a note and reason for removing the edits. This applies to the Symbolic Hammers section and the External Links section. Right now I am dumbfounded as to why you have done this, and I request that you refrain from doing so in the future without a decent explanation. Otherwise, your removal of information appears to be vandalism. Thank you for your kind attention, Gbeith—Preceding unsigned comment added by Gbeith (talk • contribs) 22:42, 11 August 2008 (UTC)
[edit] Hammer age
I believe this is the second time I have set the age of the oldest hammer. I have TWO references to refereed journals, both of which give the age as 2.6 million years NOT 2.4.
Please do not change this unless you have a reference which shows mine are wrong. Nick Beeson (talk) 15:58, 28 December 2009 (UTC)
[edit] Hammer as musical instrument?
Does anyone know how many times that a hammer has been used as a musical instrument, either in antiquity or in modern times? (Hammered dulcimers don't count.) Two examples I have heard in modern times are Johnny Cash's version of "The Legend of John Henry's Hammer" from the album "At Folsom Prison" and the Indigo Girls song "[[Hammer and a Nail]". Anyone else know of any other examples? Anyone else know of earlier uses? Orville Eastland (talk) 14:10, 30 March 2010 (UTC)
[edit] Blister?
I'm sorry if this seems like an unusual questions, but what is relevance of 'Blister' to this article? There is a picture of a blood blister, and a link to the blister article, but really... why? Yes, using tools can give you blisters, but it can also give you cramp, or a bruise if you smack your finger... etc.? Figured I would ask the relevance before removing.

[edit] Types of hammers
This english article is way worse than the Dutch article, which has a table; see http://nl.wikipedia.org/wiki/Hamer_(gereedschap) Can someone translate it and put the table on the english version ? 91.182.51.243 (talk) 15:32, 24 January 2011 (UTC)
Types of Hammers
Would like to see a more comprehensive listing with descriptions of hammers under the heading in the article ... "Popular hand-powered variations include:..." From some work I did a while ago, we may wish to add the following types of hammer...
Ant-vibration hammers, with built-in tuning-fork design to minimise vibrations
Brass or nylon-faced hammer for assembly work
Brick hammer, commonly used by bricklayers with a chisel-end for splitting and facing bricks and blocks
Bumping hammer used with a dolly for car body restoration work
Chipping or scaling hammer, often with a shock reducing spring handle, used by metal-workers to clean welds
Copper and raw-hide faced hammer, for damage-free assembly work
Drywall hammer, with a serrated hammering face and an opposing axe face
Planishing hammer used in panel beating
Roofing or slating hammer, with a spike for making holes in roof slates, a nail-extracting claw and a recessed hammering face
Scutch or walling hammer, with two combing faces for dressing masonry
Slide hammer, with a heavy weight on a guide-bar used for loosening tight assemblies
Splitting hammer, with a wedge-shaped axe-head for splitting timber
Stubby hammer, with a short handle for work in confined spaces
Would also like to cite my work on the subject, entitled "The Gaffer's Glossary - Hammers" at http://www.comparetradeprices.com/content/advice/2011/03/07/hammer/ as an additional external reference

[edit] Pink Floyd's Marching Hammers?
Lol, I think there should be a "In Popular Culture" section that mentions the "Marching Hammers" from The Wall...... --GreekRailFan (talk) 11:15, 4 July 2011 (UTC)
