Calvin19 0 #1 September 10, 2006 what thread is used for the keelpockets for line containment? IE attatching it to the Canopy.? what thrad for PCs? Also, has there been any ideas in making a pilot chute useing ZP/mash/binding tape WITHOUT useing a sewing machine? what tape is used in the PC ZP? what webbing for the center lift line in the PC? All of the shit i have i think will work just fine, but my sewing machine is getting kinda tired, and the whole point of this is to try something new and different.

GreenMachine 0 #2 September 11, 2006 Hey Calvin, For what it is worth: I have been reading a series of articles on building your own hot air balloon In there the idea of using glue/expoxy to bind nylon together was mentioned. The author then cited Dan Poynter's Parachute Manual and said that type of seam binding had been tried and tested. The results were that it reduced the strength of the nylon.Rigger, Skydiver, BASE Jumper, Retired TM Share this post Link to post Share on other sites
nicknitro71 0 #3 September 11, 2006 Keelpockets? As in tailpockets? In that case E thread. E thread for PC. Binding tape for PC. No webbing is used in PCs. Good luck using glue instead of stitches Memento Audere Semper 903 Share this post Link to post Share on other sites
Calvin19 0 #4 September 11, 2006 Thanks! the webbing in PCs i was talking about was the center lift line, it looks like binding tape, just wanted to make sure. i have no binding tape, so that will get here when i order it. E thread, good. my weeny machine will handle that. thamks. as for glue, i had no ideas besides sewing, moslty just curious. I have used cyanacrolate to bind fabric together in hanggliders, but usualy for non-critical places, or where a machine cannot be used due to thelocation of the stitch. i use cyanacrolate glue to stop thread from unweaving. the glue is pretty nice. andf yes, i was talking about the tailpocket. keelpocket, whatever. sorry.

TomAiello 26 #5 September 11, 2006 I've seen a BASE PC in use with the Seattle crew that has no centerline. It's constructed (by one of their local riggers) as a hemisphere, rather than a flat circle, which makes the centerline optional, per the manufacturer. If you were to do that, of course, you'd be a test jumper, with all the small print that entails.-- Tom Aiello Tom@SnakeRiverBASE.com SnakeRiverBASE.com Share this post Link to post Share on other sites

Calvin19 0 #7 September 11, 2006 A hemispherical PC has problems that i can see already, and a few benefits. Hemi PC- BAD- not as much drag for fabric surface area due to projected surface area, if packed weird, depending on the size of the pc it could make for a long throw out arc, maybe it wouldnt all come out. GOOD- the PC would be deeper, so it would occilate much less, there would be nothing on the inside of the pc to snag for a second on the fabric of the zp.

Calvin19 0 #12 September 13, 2006 also, the pocket is lockated on the keel of the canopy. (centercell, on top of the center rib) and i would get the tailgate and tailpocket mixed up. so i made up a new word. Share this post Link to post Share on other sites
TomAiello 26 #13 September 13, 2006 You should consider calling that little round parachute a Bridle Chute. Tenacious B decided that was a more descriptive name, and is now in the process of bribing jumpers all over the world to adopt the term.-- Tom Aiello Tom@SnakeRiverBASE.com SnakeRiverBASE.com Share this post Link to post Share on other sites

Calvin19 0 #16 September 13, 2006 this was a meshless pc correct? as in there was ribs that led to the canopy? in a spoke fashion? Share this post Link to post Share on other sites
TomAiello 26 #17 September 13, 2006 Negative. It has ribs made of tape, but there is large hole mesh stretched between the ribs.-- Tom Aiello Tom@SnakeRiverBASE.com SnakeRiverBASE.com Share this post Link to post Share on other sites
Calvin19 0 #18 September 13, 2006 i request a picture. I have seen and used bailout rigs with a meshless pilot chute, that had no openings, it is hard to explain, i am going to try to find a pic of one on google image. these bailout rigs were 40s military, and later converted to civilian sailplane/aerobatic bailout rigs.
