    Double finger trap

    In my experience it's easy to do .... but can be hard to 'un-do' without damaging the line. (Especially if it was done sloppily in the first place, going through line fibers.). On coated Spectra it's easier. On Dacron it can be a nightmare. Uncoated Spectra, like a PD reserve, also a nightmare. I have not done it on Vectran or HMA. I've had to replace quite a few LST's/ toggle lines because of this practice. In my opinion it should never be done on a reserve (but always follow mf instructions, obviously.) It's an ingenoius technique. I love it for adjusting PC kill lines in a hurry. But, for me it's too hard undo without damaging the line to use it for toggles. Why not just use a fingertrap, then a knot? I'd honestly rather pick bartack stitches than undo a double fingertrap.

    Peregrine Ace MARD

    Good luck with that. Their website either works, or it doesn't. Mainly for me it doesn't, especially when I have a Glide customer sitting here in front of me.

    Swift reserve manual

    In addition to the strange brake setting: Please test the fabric on this Swift reserve. I packed some Swifts in my early rigging days, hoping they'd go away. I had some Swift and Cirrus reserves come through my loft in the late 90's to mid-2000s. We sent them back to ParaFlite, and they did not pass their own porosity or strength tests. So they were grounded. Based on this, I won't pack them. I'm glad that you've gotten links to the manuals. But, please test the fabric before you repack this 30+ year old reserve, because the fabric might not be airworthy anymore. Someone's life could depend on it.

    Has anyone used scrisc.com

    One of my rigging customers just ordered a new Cypres from them. He paid something like $1220, and got a free Optima alti with it. Shipment came from Deland, so evidently they have a presence there. No complaints. Fast shipping. Very happy customer. My experience, for what it's worth. -D

    Standard, semi stowless, or stowless?

    To this ^: Semi-stowless is the way to go, in my opinion. You'll still have to get the canopy in the bag (obviously) with a couple of locking stows. But then you can 'figure-eight' the lines: Much easier and faster. I don't like the various "full stowless" bags that only use magnets. It's hard to get the canopy in neatly, and the canopy/container volumes need to match. Less room for error. We've seen a few instances where a magnetic bag snatched onto the the trailing edge of a canopy (landable,) and other instances where incorrectly-packed magnetic bags have caused bag lock (not landable.) I've recommended semi-stowless dbags to my new gear buying rigging clients for a few years now, and they love them. Hope this helps, -H

    Military PEP/ non-TSO'd

    Question: Is an old military rig legal according to FARs as PEP for a pilot in a Cessna 182? My DZ just bought a 182, and this rig came with it. It's a decades-old military back with no DOM or serial #. Obviously no TSO. It has Capewells, cones, and tons of (? pull-the-dot) annoying-as-hell snaps. Also many pack opening bands. I won't work on anything that's not TSO'd, and I don't have the tools to pack this thing anyway. We'll be getting our pilot a better, more current PEP rig. My question is whether this rig would be legal for a 182 pilot according to current FARs. I read through them, but couldn't seem to find an answer. The former 182 owner and his rigger (very nice guys) swear this is legal. Thoughts? I'd be grateful for any input. -D

    Mirage semi-stowless bag question

    Hey Diezel, Many of my people have switched to semi stowless bags, mostly Mirage and Vector. I haven't seen any difference in bulk distribution that alarms me. This time of year here in NC, I'm constantly shortening closing loops. I think most people underestimate the drastic effect that climate conditions can have on pack volume and loop length. Take care & stay safe.

    Saving Veterans With Skydiving

    Excellent article! Very well-written. Jim: I loved having you at TSC. You are making a difference. Safe travels to you always. To the author: Quincy Jones is an iconic music producer/composer, but he doesn't take skydiving photos. Please edit lede photo credit to the awesome Quincy Kennedy at SCD - thanks.

    HMA/Vectran/Dyneema ID

    I love all of these dimensionally stable line types. What I don't love is how to tell them apart. Is there a way to determine which type of line is on what canopy? I'm especially interested in how to differentiate HMA, Vectran, and Dyneema in the field. Thanks in advance, -D

    Vaping/e-cigarette fluid spilled on rig

    Interesting that you said this, because the manufacturers were asking me if I could specify the flavor: was it cinnamon, black licorice or banana? (I don't know. Smelled overwhelmingly like caramel/coffee to me.) Evidently some flavors can be corrosive to and/or interact with plastic ... or nylon. The rig is a WIngs, the reserve a PD. Both the most excellent Heather at Wings and the folks at PD have been very helpful with this. But it's a new one for them, too. Obviously when in doubt about any substance: wash it out and test when dry. Any further doubt about degradation to the nylon: contact the Mfg and send it to them for testing. We don't know who spilled the juice on her container. I'm taking care of it, and won't charge her for it because this was an unfortunate accident that wasn't her fault. We do have a new rule: No vaping or vaping fluid allowed in the building or hangar. Outside only. I appreciate everyone's input - thanks. -D

    Vaping/e-cigarette fluid spilled on rig

    Appreciate it - thanks! Research (Googling ) doesn't show anything harmful to nylon, and manufacturers are looking into it as well. I'm still washing the rig for her because the stuff is oily and the odor is overwhelming.

    Vaping/e-cigarette fluid spilled on rig

    One of my video people came to me this morning asking me to look at her rig .... someone had spilled 'vaping' fluid all over her back pad. The strong smell was the same that we get in puffs of 'vape' sometimes in the hangar. The substance was very oily. She had blotted/cleaned most of it off before she brought it to me, but her backpad was saturated. I grounded her rig, because I had no idea if this could be harmful to the nylon. I'll be contacting manufacturers in the morning to see what they say. At the least, I'll be cleaning her rig to get the smell out. In the meantime, I'd love to know what you think: Was I right to ground the rig? What would you do? Appreciate any input. Safe rigging, -D

    Closing loop too long

    I'm with Michael. I'm getting the idea that a lot of people may disagree with me, but here goes

    Freebag testing and development

    I think the bigger question is: How are the PC and bridle going to extract the freebag from the rig.

    Electronic Rigger's Log

    Just curious, would riggers be interested in an online service that makes logging, billing/invoicing, and serial number lookups easy? Interested enough to pay a monthly or annual fee? This is an excellent idea! Especially for SBs. I might be ... but most of us don't have a lot of income for something like this. I track everything as I work in a paper notebook out of habit (I'm old,) but also put everything into a database (MS Access) and all contact info in Google. It's just easier, and more reliable/portable. I've even learned some SQL so I can do database queries. Excel would probably be easier, but I've always sucked at it. I have never used the commercial logbooks. The FAA has looked at my stuff and they've been fine with it.

    You are always so incredibly helpful on this forum ... to new, prospective and old riggers alike. Thanks.

    New Aerodyne softlinks

    Wow, that's crazy! The VAST majority of my experience with soft links has been with the PD brand. While I knew metal on metal can cause problems, I've never seen anything quite like this. This one took me by surprise, because of the low jump #s on this rig and the major damage to the riser. It only takes a few minutes to tack slinks, and pushing a blunt-nosed curved needle through a riser doesn't do it any damage. Untacked, exposed soft tabs are usually OK, but they have lead to link failure, steering line hang-ups, numerous cutaways, and (if I remember correctly) at least one fatality in AZ years ago. I always prefer to tack soft links. I'm happy to see Aerodyne get rid of the rings.

    New Aerodyne softlinks

    Hey DHemer, Many riggers won't look at your main, unless you specifically ask them to do so. Have someone tack your main links. Not critical, but definitely a good idea.

    New Aerodyne softlinks

    In addition to link failure, This is a serious issue that can also lead to riser damage, if the slider grommet and metal link tab are guillotining the TY17 on each opening, as in the attached picture. These were new Mirage risers with maybe 80 jumps. So, please: Everyone, do tack your main link tabs inside the risers. I know of many malfunctions and slink failures due to unfortunate slink tab/brake line interactions, and wear. I'm happy to hear of any/all manufacturers doing away with the metal rings! I agree with not tacking reserve slinks - just set them properly and be done with it - but would not fault any rigger for doing so.

    Reserve Closing Loop Material

    No, not that much force, surprisingly. I've had a few of these defective washers: most recently ~ 3 years ago on a rig that was out of service for some time. That one failed when I was pinning the PC on a Javelin (no leverage tool.) The few that I had, tore completely between two of the holes. At that time, I talked to SSK and they seemed to think most of them were already out of the field. Hopefully this is a thing of the past, but it never hurts to keep in mind. I have only heard of them failing during closing, and not during use of the rig. I stopped reusing old Cypres washers then; if I'm not confident the washer was pre-SB, I replace it.

    Routine soft link check during repack

    I usually do invite the rig owner put the rig on and practice EP's, especially if they have low jump #s and/or are uncurrent, etc. I just like the idea of a 'discount' on a rig I regularly maintain anyway, because some of these nasty surprises cause me more time and effort.

    Routine soft link check during repack

    Best idea I've seen in a long time, I may adopt this. Less work for me if things are set up like I want (bumpers tacked, etc.) Love it. -D

    L bar removal

    NovaTTT and drjump: I used to have a little iron tool that was similar at Carolina Sky Sports, it was a wedge no more than 3" high that sat on a iron base, that fit inside the link. Loosen the screws, put it on there, and one little whack would have it separated. Might have been homemade. I can't find anything similar ... if anyone has a source for something similar (or would make one for me) I'm all ears. I thought of and tried the tapered packing paddle thing two weeks ago when disassembling a Sigma reserve. After that and many other methods (screwdrivers, tapping the partially unthreaded screws, etc.) I had to walk away in frustration. Three riggers, a plumber, 4 strong guys and over an hour later we got it done. Turns out someone had loc-tited the screws thoroughly with RED loc-tite. I still need to inform my DZO that we need to order a new set of L-bars. Luckily no lines were damaged in the process.
