Thanks guys.Ed, the 13.5 inch would be perfect. Thanks. I’ll need to cut it into 8 pieces to test how well they will all fit along the inside circumference of a custom 11″ tube I made. I can drive by…   Read more»

Ken,I have a 13.5″ piece you can have, or a 3′ section section from a PML Quick Switch motor mount kit you can use.Ed

If you cant find one in boulder/Longmont area, I have a 23.5″ piece up here in Loveland.

And congrats to John Wilke whose I216 flight was officially recognized on the Tripoli record site, too.Thanks, Adrian – I see you poking around up there on I motors as well :DI understand there is a new set of rules…   Read more»

My congrats too Sean…

Congrats on the record Sean. That is super cool.

Great thread! I just received an email that I am now a new TRA record holder for the H staged class, so I am trying to close in on Wilkes TRA holdings!http://www.tripoli.org/Membership/ContestsandRecords/RecordHolders/StagedClusteredClassRecordHolders/tabid/126/Default.aspxActually I went for the low-hanging fruit as there…   Read more»

Exactly what I’m talking about – except that I wrap the packets in different # of layers – one packet with one layer, then 2, then 3, etc. That way they pull apart in the order I want to prevent…   Read more»

Since the pictures were taken, I have moved to masking tape instead of the electrical tape. I’m more lazy than environmental and cutting all those little pieces of tape was too much work. I got an automatic tape dispenser from…   Read more»

Holy crud, Doug! No wonder your rockets always deploy perfectly. Bret, you couldn’t have had a better display.

That is Z folding extreme! I remember that fixture. Doug likes making things to make things easier. I think he just likes making things. 🙂

OMG, I recognize that fixture. Z folds or taped bundles or carpenters chaining, whatever you want to call it, is like adding elasticity to an otherwise more rigid and finite length of shockcord.

Here is a couple of pictures of Z-fold

the z fold is like what you see but laying flat going back and forth in a z like fashion. It is easy to do with the nylon cord that a lot of us use and also the Kevlar flat…   Read more»

Thanks for the pic Tony. Warren, can you explain the “z-fold” a bit please? This is great information guys and I really appreciate it!

I think this has become one of the best threads I have seen here in a long time!

Personally I’m a masking tape Z-fold guy…1 layer where I want it to break first, then 2, then 3, then 4… in 4 bundles. Has worked well so far. I use masking tape because it is cheap and biodegradable.

Yep..that’s what I do too.Tony

Well, JW, I agree with you on LONG shock cords, my L3 100 foot can attest to that. Although this guy, JW, doesn’t use masking tape to reef the Kevlar, he uses electrical tape! I have yet to use latex…   Read more»
