March 18, 20188 yr I usually don't watch internet videos for more than a few minutes, but this one is well worth the watch!! Thanks for posting cliff
March 18, 20188 yr I love this video, seen it before and I could watch it another 100 times in my life.
March 18, 20188 yr Author Now I just realized sumpin. I've been jonsing to try this for a while and played around with several ideas. Even some tomfoolery about a heavy jig to bend the stave in the curve and run it across a jointer. I mean really tool intense Dumbstuff. Just a few years ago there was NOTHING on the internet about coopering I even bought a book purporting to teach it and all they had was stupid pictures of some tools But I just realized sumpin. All I gotta work out is the angle and general width of the stave. That's it. The double ended taper I put on the stave to get a the curve in a cask or barrel is irrelevant unless I have some one else's dimension or barrel volume I'm working to. That taper merely defines the way the barrel curves in and it can be anything I please so long as it's not so steep as to make the wood break when I bend it.
March 18, 20188 yr You can do some simple math to figure all that out Cliff. If you know the diameter of the end ,and the middle of the barrel, you can calculate the rest. Example: if the middle of the barrel is 18" in dia., the the circumference = C= 3.14 X18" = 56.52" the distance around the barrel at the mid section. Take that distance, 56.52 and divide it by the number of staves you want, say 26. 56.52 divided by 26 = 2.17" is the width of the stave at the middle. Do the same for the ends of the barrel. If you want the ends to be 14" diameter then C=3.14 X 14" = 43.96" around. Divide that by 26 staves, 43.96" / 26 = 1.69" wide. which means you have to taper off off 2.17-1.69 = .48" / 2 = .24 "off each side. The stave would be bent or formed , 18" diam. - 14" diam. = 4"/2 = 2" bend from middle to each end. The angle on the edge of the stave would be 360 deg. divided by the number of staves (26) , 360/ 26 =13.8 degrees divided by 2 = 6.9 degrees. Thats how I would do it. Keith would probable have an easier way, he is the math guy. Herb

The Cad program will let me draw the finished barrel, split it into staves, then break it into component staves, then Straighten the staves out and let me dimension the stave in it's flat form. But it wouldn't give me the trade skill to make the stave and that was the sticking point. I was stuck thinking that I had to make some kind of progressive curvature on the stave and that's just not true. I got it from some dumb book probably written by an academic who had never done it. You know an expert ( ex -Spurt).

I don't know Andy or how to use Excell, CAD, or spread Sheets, just know 6th grade math, I do all my drawings,and calculations on a scratchpad with a carpenters pencil. Also type with 2 fingers while looking at the keys. Herb
March 18, 20188 yr Might want to look at the Firefox series of books . Coopering is in one and you can get most of the books for 5 to 10 each at used online bookstores like Thrift books.

You know an expert ( ex -Spurt). Definition of an EXPERT; X is an unknown quantity and a spurt is a drip under pressure. ...another; an EXPERT is someone with a briefcase, that flew in from a 1000 miles away, that knows even less about the problem than you do. Generally, that just guess at the solution, fly back home and send someone else when the fix doesn't work. I, like I'm sure many other here, have dealt with both types.

February 18, 20206 yr The linked article is dated 12 years before the video posted here. Internet search of Cooper George Smithwick has stories after 2006. With a little luck he has since recovered from the fire.
