Looking at yours @KaoS did you reinforced the opening?

Yes.  I sewed triangles of 4oz dacron tape about 15mm in from the edge at each of the bridle points.  Then I did a double fold hem all the way around the front of the snout with 500 lb dacron cord inside the hem.

Most Spikes I've seen have a tendency to sit upside down because the small amount of extra fabric in the eye panels is heavy enough to make the "top" of Spike heavier than the bottom.  To overcome this on mine, I sewed a small zip pocket to the bottom most seam on the inside.  After experimenting with different amounts of weight, I ended up leaving a small bag of rice in the pocket.  Now our Spike always reverts to standing right way up.

Thanks will beef mine up.

By the way, once you've finished it and have it tethered out, small kids and their parents will flock to it.  Couple of things to consider...

1. Kids pull awfully hard on the spikes if you let them - even if you don't let them, they still try.  The spikes will rip (or rip off) fairly easily regardless of how well you sew them on.  That's not because you can't sew very well, it's because of the mass of Spike.
My Spike is 3 metres diameter.  The fabric weighs about 10 kg.  The air inside it when fully inflated weighs about 14 kg.  Imagine a sack of , say, dog food that weighs about 24 kg... and imagine you've sewn a spike on the side.  Now a ten y.o boy comes along and gives it a sharp tug.  The sack stays where it is, the spike in his hand doesn't...

2. As I've just shown you, the mass of Spike can be considerable - in my case, over 20kg.
  An enthusiastic Mum lets her toddler run up to Spike just as the wind changes and Spike rolls toward the toddler.  Even though Spike deforms and "feels" soft, he will bowl an unsuspecting adult over.  You can imagine how much damage he can do to a small child.  I know, I've seen it happen.

Ok that stuff l didnt consider. So torn spikes and knocked over everyone. Will now be careful where and when l use it. Maybe make a few extra spikes for the inevitable. Thanks Kevin.

I wonder if you would be better off just to use velcro to attach them??

This way they can still require a reasonable amount of force to remove (depends on the amount of velcro), yet will not damage, should it happen?

[Darren Tibbey]

Might leak to much air leaving it saggy id reckon. 

[Darren Tibbey]

Material is here from PL. Start cutting end of this week. Start making next week.

Templates made cut cut cut. Weather sux cant even try my bow and arrow.

[Dingo]

Yeah. But the forecast for the weekend looks somewhat promising.

With a bit of luck I might even get some practise time in on my Bora.

[Dingo]

My sacrificial offerings (and my optimism) to the weather gods have paid off . I´m off to Bicentenial Park for a fly. yahoooo

 

[Darren Tibbey]

Cutting cutting. Lots of cutting.

Eeerrrrr what have l done.

[Darren Tibbey]

Run short have to order more. ?

[Dingo]

Le´me guess.... it´s some kinda gigantic shaggy??

So will Spike make it to Sandy?

[Darren Tibbey]

Doubt it now l have run short of material. Takes over a week to get it from NZ. Still havent started all the sewing yet. Like @KaoS said its surprising how heavy the the material is alone. This is going to be a kid killer.
