Triple zig-zag stitch

[Powder_pig]

I am a newby who lives in the Portland area and have built several duals and one quad. I was at Lincoln city a two of weeks ago and ran into a couple who took John's quad course. I was interested because I just finished a "B" rev rip-off fully vented. I had never flown it, or any quad for that matter, and asked my new friends if they would fly it. Barely enough wind to get it off the ground but it does fly. I am in the process of building a non-vented Freedom for lighter winds.

Long story.

I am a graphic designer and am into designing my own look. I examined a quad on the beach at Lincoln City, the one with the eyes, that (because of all of the curves) was sewn with a triple zig-zag 3/8" overlap.

Is this stitch strong enough? Should I use a straight stitch as well?

John B, if you read this remember...imitation is the sincerest...

all of my revs have this stitch and it holds up nicely

the triple stitched zig-zag stitch is generally used in conjunction with double faced adhesive tape.

This technique is nice and easy with straight lines, (Revs are like this) but Ken McNeil does this stuff on his shaped sail dualies (centenary cut ~?~) by adhering a curved edge to a straight edge. The shaped sail grabs more air so a "standard" can fly in lower wind conditions.

You don't even have to sew if you use the correct double faced product. The best on is 9460 adhesive from 3M company. You heat the material after application and it fuses the pieces with a 1/4 seem that will outlast the fabric.

Our 1point6 design is made of a single skin of Icarex material with all the assembly done as a "no-sew" using 9460 tape. This method is very light weight and strong, perfect for a huge wind range with the bottom edge resting at indoor capable and the top easily 10 or 12 mph.

Some materials can't be sewn at all, mylar scrim and orcon must be taped or the perforations will tear thru the material in moments. You can sew thru the tape, just as Revolution and many other quality manufacturers do, then you get the best of both worlds!
