Whats the best why to hem circles out of ripstop? Or is hot cutting it good enough?

I am doing a double foil sled and it calls for two circles in each panel around 19in in diameter near the tail end.

Hemming circles is tuff. If it kite ripstop, I would imagine that just hot-cutting would be enough :-D

Still working with the old tent material I have. Would I be better off cutting a long strip of material and just fold it in half. Then just form it around as I go?

It depends on how stretchy the material is and how much it frays on the edges.

If if frays easily, then you will not only want to hem it, you will also need to fold the hemming strip twice so that the exposed edges are hidden underneath (fold it in half, unfold, then fold the edges inside to the fold). If you cut the hemming strip at an angle to the edges of the material (called on the "bias" , then it will stretch more easily and be easier to sew around the circle.

As you can see, if you can get away with just hot-cutting, that's what I would do.

I agree with Grant , hot cutting would be enough. But, if you feel you need to reinforce the area, try this.

Use some dacron or rip stop tape and make a circular patch out it, of course larger than the vent hole itself. place it over the vent on each side and sew it into place. After you've finished sewing, make a template the size of the hole and use it to open up the hole. There you are, heat sealed and sewn into place. You can also do this in the form of applique. Let's say some spikes around each hole, sew the patern into place also stitching around the vent hole. Now it looks even cooler

Well the judges have spoken and hot cutting it is, to start with. On the maiden voyage if it frays, then I will try one of the other suggestions. (and the circles are only 9in not 19ins.)

Thanks everybody. :up:

I'm glad that you corrected the size of your vents, I thought man, that's a big kite. smart choice to hot cut, less work and it should be no problem as far as fraying

Note, Ken's not using kite ripstop, he's using material from an old tent, some of which is pretty stretchy. There is a fray test that someone over at Kitebuilder often recommends. Tye a piece of the material to your car antenna and drive around with it for a few days....

That's awsome Mike, Ha, Bet that would be a great way to test... Not so much for me though driving 4 to 500 miles per day at 65...

He can do the same sewing with the tent material as he would with r/s

Happy T Day

Anybody that is coming to the club fly tomorrow will see the maiden voyage. :-D Stayed up quite late last night/morning to finish it. :roll: :shock: Looks pretty good for only the 3rd sewing peice I have done!! :clap I did the hot cutting for the circles, not to happy with it, but it will do for now. I think it going to fray might try somethings tonight if I am still awake after all the turkey. :lol:

Looking forward to hopefully meeting some of the new members!! :up:

Kwel Beans!! :up:

I just got done sewing some screening material around the hole to help giving it some support. Also from the same tent, boy sure am getting a lot of use out of that tent!! :-D 8) Looks very promising. Cannot wait to try it out!! :mrviolet:

The maiden voyage was a HUGE SUCCESS!!! :bash: :wohow: :wohow: :bash: Woo Hoo!!! Had good winds all day average around 8/10 mph an hour and no signs of stress anywhere. As soon as Chris posts the pictures of the fly today you will see the kites in flight.

Again thanks for all the info from everybody!! :up:
