  1. No. Pretty much everyone flies midi and maxi kites this way I've tried that, and it sometimes works okay but it isn't reliable. The Prusik knot tends to slip when used to attach things to the line of a pilot kite. I suspect it is because the pull of the pilot keeps the flying line really taut both above and below the attachment point, so the line effectively becomes a solid rod. Kite flying line is usually really smooth line, unlike climbing line and sailing cord (which both have a reasonably coarse weave outer sheath), so there is little friction for the prusik knot to grab and hold fast.
  2. Heaps of info at http://gombergkites.com/how.html With midi kites, I lock the bridle to the lifter line with a carabiner (but a proper one, not a cheap one) Then another carabiner on the top or head connector that simply clips over the pilot line (not locked with twists), but can slide back and forth
  3. Ooh, Clive! That's the sort of name I like. I had a beagle called Eric a few years ago.
  4. Darren got me thinking when he started the thread about Spike. About time I got some of those "I'll get around to that one day..." tasks done. One evening on Corel Draw... Followed by a week of intermittent cutting and sewing... Just got to think of a name. He's about 2.5 metres long
  5. 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.
  6. 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.
  7. Looking good @Chook
  8. Made these myself. Each bag uses a piece of cordura 750mm x 1000mm. 1. Hem along the two 750mm edges 2. Cut a 2700mm length of 25mm heavy nylon webbing, then sew to the outside of the bag to form straps/handles. Sew ALL the strap that touches the bag - don't skimp. 3. Fold the cordura in half (wrong side out) and sew the 500mm edge seams. I sew a double row of parallel stitches for extra strength. 4. Turn bag right way out. Done! I use cordura because it is very abrasion resistant (and because I have some), but it isn't cheap. Canvas or anything similar would be a pretty good substitute. I also use heavy nylon webbing - you can buy it from China for about $40 including postage for a 20 yard roll. Medium webbing just doesn't look or feel strong enough. Yep, if you have enough bags, it's a good idea to set up a new anchor point before relocating your flying line. Then unhook from the first anchor and walk it over to the new one. You can even leave the kite and line attached to one bag, then move them by picking up the bag by the handles and walking it to the new location. Then just click the carabiner onto the rest of the bags at the new location. Easy peasy
  9. Yep - as big as necessary. BTW here's a clearer set of pics explaining the slip knot
  10. My 2 cents worth... Whenever possible I anchor with weighted bags rather than peg into the ground. Very easy on most beaches (just fill them with sand). Not so easy on land, but not always impossible. Depending on where you are you might find rubble, rocks. If you've got access to water, plastic milk bottles filled with water then placed in a sack make for a very useable anchor. But sometimes you just have to use stakes or pegs. Mine range from 5mm 25 mm diameter. Here I've got a cordura sand bag and carabiner, large peg with webbing strap and tie-offs, small peg with tie-offs, and long webbing strap I never attach flying line directly to the pegs, always lark's head to a strap or heavy duty line tie-off. That way the lark's head won't slip. I usually have 2 or 4 tie-off points per peg. That way you can shorten or lengthen flying line from the winder before taking off the original attachment. Also, you can anchor a second flying line if you want to have separate lines for your pilot and your line junk/inflatables. I've given up using the square sheet sand anchors that you bury on the beach. Sand can wash or blow out of them too easily, and they are a bugger to relocate. I now use cordura bags with heavy duty straps and carabiners. The big plus here is you can use as many or as few bags as you need per anchor point - just carabiner them together. And they are easy to relocate when necessary. Wind direction change, tide coming in, whatever... How to tie flying line to a carabiner?? I use a variation of slip knot Fold the line back on itself Form a loop Pull the strands nearest the end through the loop, leaving the end free Now clip all three loops onto the carabiner The will hold fast until you remove it from the carabiner. To undo, pull on the single loop, allowing the double loops to come through from the other side of the knot - Voila!
  11. I think I might have a few in my pile of used bits and pieces ;-) 6mm in both directions? Send me a PM with your postal address
  12. We scaled ours UP. Instead of the hexagons being 100 cm across, we took them to the full width of the 150 cm roll of fabric. Around 60 metres of fabric if I recall correctly. Greater cost, but less waste. Mind you, we made ours out of parka nylon, which we found at a reduced cost of about $5 per metre. That brought the cost down significantly. When you start adding up cost of the fabric and the line involved in making a large inflatable, the PL giants are great value
  13. Nah! Go big, or go home ;-) Made this one in 2000, still going strong!
  14. Jan O'Loughlin made a really cool spider ground bouncer, about 10 years ago. Coolum220.MOV
  15. @Chook might have one?
