I have always required a main PC handle that I can hit with the palm of my hand and find it if needed. That is rigid tubing or hackey, but not a lump of soft foam! I noticed on both types of firm handles especially on the hackey, a lot of flopping around and pilot chute creeping out in flicks. Sitting in airplane also walks it out. I mounted a dot fastener or snap in the correct position to peel it open during pull. Problem gone. I chuckle when I see the line up walking to load with half of them with dangling handles. They have had no "reported" problems yet. Remember, "It doesn't take much to work and it doesn't take much to not work"

That was wonderful. Thank you. I am tempted to jump the one I have. OSI scares me.

I just received a Delta II wing from a lost friend. Anyone have a picture of one inflated? I remember in the day when they would put the colored lines in groups within the "OSI".

If he knows how to properly fix the ends.

Hey, can that be used with an AAD or a Skyhook?
-
Don't forget, if trimming cutaway cables, make sure side opposite RSL is shorter. If you have RSL on both sides, get rid of it.

As you stow the lines, the groups will get smaller because cascades turn two lines into one. Thus causing loose rubber bands if all the same size bands are used. I personally mount the bands so I can grasp the flat part mounted at the bag and pull and wiggle it to snug the band around the group, no matter how small the group is. One size band works for all, and I single stow all. The snugging down is important to give more equal release pressure to all bands. Just my personal way of doing it. No problems what so ever. The "legal" way is to follow the manufacturers instructions.

He patented it probably in the late 1970's. A wonderful application for skydiving cutaways. My balloon friends remember using the design in the 1960's for a tether release. Works great under load. Just think if someone could come up with the next step, something even simpler. So far, it is a great application.

If you sell any, do you have to give Bill B a royalty? He says he invented it.

When the first pull outs came out, the handle was mounted on the apex. The pin was not pulled until arm extension. When pulled, the container was "lightly" closed. You could "cook it off" or hold pilot chute in your hand until you pulled the pin and let go of it. Bridles were much shorter and many used a diaper tail with no bag. Bag or not, seemed to work fine. Wish I had a video of that system being used. Still have one on unused rig.

When I received my senior riggers certificate in about 1973, I had to tie a surgeons knot completely crushed by the lead seal as taught by Dan Latchford at Midwest Parachute Sales and Service in Novi, Mi. He had showed me a pamphlet with the specs. Our study guide was Air Force and Navy manuals. Survival Equipmentation I and II. If the new accepted method is to leave the knot outside the seal as it appears in the new manual, do we buy that? Who wrote that manual? Did not mean for this thread to go this far. If there is no reply from Terry, the document I remember must not exist. Thank's for your time. GB

Although a minor issue, still seems to be a grey area. Thank's guys. NSCR-310

Thank's BIGUN. Good article you dug up. The FAA link says "page cannot be found". Appreciate your reply. SCR-1581

2005 is a "recent" manual. Where did they get it from? Sealing parachutes has been in use by the military for at least 65 years that I know about. They have a document and procedure for everything they do. In the 1970's, I remember a seeing a document showing the knot and procedure. Since then it has been a free for all, including myself. It is a minor issue, but I wanted to show the junior rigger the proper document at safety day when I see her. Once again, does anyone have access to a document showing this procedure, not from recent manuals or opinions. I do thank you all for your replies. FB #143

I was asked by a junior rigger if I had any documentation on how to seal a reserve other than the new rigger manuals. I thought that many years ago I saw a military description of how to route the thread as well as the "legal" knot to tie under the crimped seal. There are many methods in use and most work fine. Does anyone out there know of any military reference or FAA service letter etc. that describes the proper way to seal a reserve? Not just your method or opinion. Thank's GB1

You can break anything if you do it right.

I had a Switlik seat pack where the outside of the pack was actually the top of the rectangular pilot chute. It had pre bent spring strips mounted internaly. Don't think that is what we are after, but some of the old designs may have a place in some future designs.

This is just the kind of response I was wanting to see from any of my posts. Someone who is thinking outside of the box to help develop new ideas of what could become the norm. I am sure there are several ways to make this happen with the pull out reserve (POR). ha ha It takes the ideas of many people, experienced or beginners to hit on the best changes. As far as the stretchy stuff remaining airworthy for 20 or more years, put it on the rigger to check and/or replace at intervals. By then a longer lasting replacement should have been developed. "keep it simple" is important. Don't rule out other ways to launch reserve with AAD. Secondary spring pilot chute, explosive charge (not really), jump spring under bag, etc. Rigger Rob, THUMBS UP!

Back in about 1975 or 1976, Jay Hilden and Mike Cerosoli showed up in Athens, Mi. to form the first 29 way round. They had the first throw outs that came from the Wonderhog shop. Wonderful concept. Pull outs came later and so did curved pins for the throw outs. The first curved pin came from a hardware store door latch that we bent. At that time, Sandy Reid and I mounted the pilot chute on the bottom of the container. Thus, the first BOC. There were a few different designs for the pull out. With the pud on the bottom of pc and a container that just burst open upon pin removal was quickly seen as a bad deal. With a few changes, the pull out configuration became more reliable to us than other systems. That is why a few of us used a pull out on our reserves.This presents another problem. AAD on pull out? Did not matter back then. That would take at least another weekend of pondering. Right now for the general public, the marketed throw out is the best thing going that they can buy. D-3411

Old on paper. Young in ideas, I hope.

I appreciate your reply. These spools were perfect for tacking where nylon 5 cord was needed. Circa 1975

A while back, pre-wound small spools of 5 cord nylon, waxed were available. They came in black, white and sage green. Perfect for rigging kit. They were about the diameter of a 50 cent piece. Anyone know if there are any more available? They looked like a pre-wound bobbin.

Jerry, Thank's for straightening me out. When we received the first pop top to modify for use above the main, I remember opening the package from Ted. After the first one, we made our own and Ted was paid a minor fee ($5?). Thought he invented it.
-
How about the Reflex? The external pilot chute was a great invention by Ted Strong on the Pop Top reserve. Johnboy got permission to borrow it. It seems to be the best out there to get clean air unless if there was a pull out available.
