I have read a lot of your blog, I find it ...Hi Drew<br />I have read a lot of your blog, I find it very interesting. I am in agreement with a lot of your jackline and tether info. I am making tethers, and I am sourcing my supplies from a rock climbing supply company. I have seen you refer to "proper sewing" when suggesting that one could sew one's own tethers, and I wonder if you would elaborate. I have sewn some tubular webbing up into test pieces, and had my stitches ripped out by a local rigging and supply company, to try and quantify the strength of my stitches. Up to now, I have sewn box stitches and partial box stitches to reach a stitch that will "give" at 500 lbs. This is for a flag that will give the user an idea of the stress the tether has been subjected to....<br />For making the major loops that secure the spinny shackle and two locking gate clips, I have been using a series of rows of bar stitches. If you have a better and stronger stitch type suggestion, I'd like to hear of it...<br />I am also doubtful about the use of the quick release shackle, as a way of releasing the harness from the tether, WHEN UNDER THE PRESSURE OF THE WEIGHT OF THE PERSON WHO FALLS OVERBOARD. Two things: such an unfortunate person would need to temporarily unload the weight on the shackle to get it to release. Secondly, the key ring type of connector between the spinny shackle and the row of beads one is supposed to pulltto release, might very well pull out and leave the overboard person with a handfull of beads and his tether still attached to the boat! I am currently eliminating the ring ding and running a loop of 1/16 inch SS stranded wire through 4 beads and through the stem of the spinny shackle pin, so you will either pull the pin or not have enough strength, one will not normally be able to break the SS wire. There is actually more to the tether story, as I have been in contact with the international offshore group, and their requirements for tethers are not well thought out either. Also, If you need some stitching done, I'd be glad to help out.

But...<br /><br />It's leaking 50,000 gpd.<br /><br />This is their chance to show that they know how to respond... or not.Drew Fryehttps://www.blogger.com/profile/06013965677534522281noreply@blogger.comtag:blogger.com,1999:blog-5399150767029697926.post-1463011108552811952010-05-04T21:30:01.568-04:002010-05-04T21:30:01.568-04:00Hi Drew; It will be something to watch closely. M...Hi Drew; It will be something to watch closely. My theory is; if the well leaks 5000 gallons of oil per day, and a gallon of oil can cover 2500 sq feet by natural dispursion on water (not including wind and waves). Then in 30 days the coverage could be as much as 71,000 sq miles. The Gulf is about 310,000 sq miles in size. So, it could be possible that the spill could cover 25% of the gulf in only 30 days. Additionally the Straits of Florida and Cancun gap are the only two ways in and out - with the Cancun side being the largest exit flow point. It pretty scary to me...
