    Riser design & toggle fires

    After building many sets of toggles, one of many things I learned is that using a zig zag stitch on the upper tongue causes more abrasion and rapid wear on the brake eyelet on the brake line. Early on it was found that multiple straight stitching (301type) eliminates the wear on the "cat eye". The toggle with the downward tongue requires a wrong direction pull on the pocket it fits into. Eliminating the bottom tongue simplifies the whole system. For now that system works but could go to the next step quite easily.

    Riser design & toggle fires

    This an industry wide problem that has been mostly unreported because people did not have it happen on the next jumps. When the slider makers went to the premium quality stainless grommets, they elected to install the ones with an inside diameter of 15/16 in. Real bright. The old style #8's have an ID of 1 1/6 in. The riser and toggle material is mostly 1 in width. Then, slam a size #0 grommet in the toggle handle and it becomes more than 1in wide and rock hard. Try putting that through a 15/16 in hole. Guess what, you will have a jamb up or worse a toggle fire. A jamb up will cost you critical time upon opening when you are getting control of the canopy. A toggle fire will swing you around and maybe twist lines leading to a cutaway, even if you are not jumping a hot rod. I installed real #8's on my slider and built quick draw slim toggles. Either will drastically help the problem. After 2 toggle fires and multiple jamb ups, it is now just a memory. Then you will get the folks that say "just install bumpers" and live with your slider flapping, slowing you down, and obstructing your vision. Remember, It doesn't take much to work, and it doesn't take much to not work." Good Luck

    Did you have slider stops at the top side of the risers?

    Preventing Hard Openings

    Anyone here wise to the secure slider mod from Ray F from Yolo ?
  5. Jerry, you have a good memory. Sheeks could be one of those people. Always good to hear your comments. Obvious you are one of the more wise people on this site. Jim T
  6. Sheeks, your idea and concept may have body to it or may have draw backs. It is people like you, with those kind of thoughts, that will push the equipment forward. Keep thinking not only of the line eating sliders, but anything you may question that could be better. If you can figure how to get rid of the slider, you hit the jackpot. I respect your thoughts.

    RSL material behind the ring

    Mostly newer jumpers can be very stupid. They think that just because it is an "approved" rig and reserve is in date, nothing can be screwed up. They say "it's all good". As long as they look cool and are patted on the back by others is their focus. Remember, It doesn't take much to work and it doesn't take much to not work. Good Catch!

    Certificate numbers

    Wait for new number. Go to faa.gov. I made my rigger, A&P, and pilot number the same. Write "pending" for now.

    New RI mard? Riggers?

    Two weekends ago I was in Eloy. Sandy and I had the run of the shop for 3 days with nobody there. He showed me how to pack the mojo. Although I am not totally sold on mards, look's like this one is the best so far. RI is big on exploring new stuff. They seem to go almost over board on engineering if there is such a thing. This leads to coming up with the next step as far as advancing the sport. I am sure that, in time, there will be another model by someone. Keep it up everyone, full speed ahead.

    Proper way to seal reserve

    The last time I spoke to Dan was at the Midwest Skydivers Reunion in 2014 in Michigan. He mentioned that he did not write that manual, he just compiled information that was already out there.

    New rigger

    Learn the other stuff he is doing. Learn how to use the harness machine and all the others. Do more with him than just repacks. You will gain the respect of the right people when they see you are more than a packer. Of course they will bring you pack jobs when they see you can do the other maintenance required.

    Shortening laterals

    I saw a rig with a situation like yours. I noticed that someone had put an "S" fold in the webbing and sewn it to shorten that horizontal back strap to see if it would fit better. Not sure how legal that would be. He said he had over 250 jumps on it. I suggest you send it to the manufacturer for proper fix.

    favorite sewing machines

    The problem with the throat to presser foot dimension on a 217 is that the upper thread tension seems to release early, at least on my 217n-08. By removing the internal activation lever and carefully heating and bending it just a few thousands, the tension will release at a higher foot height. If you raise the foot, there are more problems to deal with like needle bar hitting foot. That can be cured with a lot of time invested. I do not recommend that. The 217 is not a heavy duty zig zagger. It is more of a light medium grade machine.
