keet: did you know that your post here has nothing to do with the topic of this thread?

Ed, did you know they use coil springs in those semi-automatics that you'd like to see severely restricted in the U.S.? But they use flat springs in the large capacity magazines that you would also like to see severely restricted. What conclusions can we draw from that? ANTI-GUN POSTS by ED GOOD It proves that Ed Good doesn't know shit from Shinola- Askins book was written when gun makers had different metallurgy and machine shop practices at hand- Today we have CAD-Cam, cyro-metal treating, aluminum and other non-ferrous alloys for receivers, etc. Askins, like Paul Curtis, were fine gun writers for a different era--many of the "fine" gun makers of that era have been out of business for decades, what does that tell you? Bugger off, Ed..

foxie: much of this thread is a discussion of the pros and cons of pre ww2 era classic american made sxs shotguns, which is the topic of much of askin's book...perhaps it is you who should bugger off?

As I see it the action of a coil spring is probably a combination of beam & torion but more beam than torsion. Please do not take this as an insult, but the way you see it is not only incorrect but also impossible. All coil springs, be they tension or compression type, experience ONLY torsion during compression or extension. The laws of physics are quite immutable and the operation of coil springs isn't debatable or open to interpretation. The diagram shows a part of a compression spring that supports a compressive load P and a section of the wire cut by axial plane. The part of spring shown in the figure is in equilibrium under the action of the two forces P and resisting torsional moment T.

Ed, I am a welder by trade, and thanks to my grandfather and father, both master machinists, I know metallurgy and metal fabricating techniques.I know that anytime you or some other NE based idiot also named Ed use an oxy-fuel torch, with a neutral flame temp. at the cone of almost 6000 degrees F--to 're-case-color (or colour if you are fucking-up a British made double gun I suppose, that indeed, you don't know shit from Shinola about double guns and the gunsmithing skills required to properly care for them. The shotguns of the Askins era are not up to handling the shotgun shells of today's mass marketing ammo companies, with the exception of the RST shells, made for lower pressures and chambers less than 2.75" inches. One of many reasons my 5 LC Smith 12 gauge guns are in first class workig order is that I only shoot RST shells in them.The other reason is that I bought them over the past 20 years from private owners- men who, like me, believe in "wear with care" and would never be a customer/client of Doug Turnbull or the DelGrego clan, because they believe, as I do, that "restoration" of a fine older double with careful usage wear allowed for, is th vade mecum--abd Askins was not a gunsmith, he was a gun writer, ditto Curtis- they could have cared less about gun repair/restoration, they were rich and had qualified gunmakers at their command. Bugger on!!!

Dewey; I have springs on items from the 1850's thru 1870's (Not gun related) which are I believe called convolute springs. These springs are wound in a cone shape from flat stock much like a clock spring. They however work by compression & not by winding up as in a clock spring. So, what action would you call them, I see absolutely no evidence of torsional movement as they are compressed & this should show on the wide, thin cross section if it were present.

Now we're into some different stuff! What you're referring to are called "volute" springs. These are basically a very thin "beam" wound into a spiral coil. When compressed, one "side" (it's wound in a spiral) is placed in compression while the opposing side is placed in tension, thus mimicking beam loading but not in a planar fashion.

Dewey; Correct, volute not convolute. I am still not convinced that a common wire coil spring does not have some of that same beam acton, along with the torsional action.
