  1. Don, That's a great story! And thanks for including the link to thingiverse; others in this forum should explore it to see what else a 3D printer might be able to accomplish for you. There are TONS of models that can be printed if you don't want to invent them yourself; unfortunately, not many models are kite related (*yet*) but there are a few. As our forum conversations go, we are discussing the use of 3D technology for kite parts and modifications but you make an excellent point: You shouldn't consider that this is the only purpose your printer will serve. Rather, consider it like
  2. Reply to Frob, Great points about concerns regarding strength and mechanical properties of a 3D printed part. There are many adjustments that can be made during the "Slicing" process that can make your component weak or strong, independent of the material you are printing. Getting that right can make all the difference. The "litmus test" is to stress test the part after it has been made. For connectors I use drill bits to fit the connectors at their differing angles and pull very hard until I break them. When I can barely break them or not break them at all I call my part good.
  3. 3D Printing Example Here is an example of a problem that I solved making a part with my 3D printer. I’ve been in the process of getting ready to go to Long BeachWA the week of August 17th to enjoy some time away with my wife and some good wind and hopefully some good company of other kite flyers. Anyway, I had a long list of things to repair and check to get ready. After I repaired my kite and assembled it, I was bothered by one thing I never liked about the Rev LE; the rods on the ends droop below the LE pocket and don’t support it. This isn’t ideal in low wind. One morning I wa
  4. 3D Printing Workflow This post goes out to Riffclown, wanting to make parts that don’t exist... Note: I have intentionally not included links to the software products that I mentioned because versions and websites change frequently. Instead just Google the bold-faced product names and you will find a current link. It sounds like many of you are experienced with the process of 3D printing, but for those of you who are not and are considering it I would like to try and explain, as simply as possible, what you need to do to make a 3D print. I tend to be slightly verbose in my ex
  5. Hello Don Fibonacci, The most common material that is the easiest to print is PLA. I use a variant designated as PLA+ and have been using the eSun brand exclusively with excellent results; this brand is what our Public Library uses city-wide and was recommended to me, and I can see why. PLA+ varies by manufacturer. Each have tried to improve the mechanical properties of PLA and eSun has done a very consistent job of it. In following posts I plan to describe my experience with materials. ABS is very difficult to print with an open-frame printer. ABS requires very tight ambient t
  6. Great! I’m ecstatic that there is an interest in the subject. I will start with my personal discovery of this technology. Almost a year ago today I was trying to create some rather complex kite-flying related parts and planned on making them with my available shop tools. A friend of mine suggested that I consider 3D printing them; note that he knew absolutely nothing about the technology but had heard about it. I shrugged it off remembering that my children’s High School had purchased a multi-thousand dollar printer and kept it locked in a room so the kids couldn’t break it. Too muc
  7. I would like to propose a new topic relating to the use of 3D Printing technology to create parts for building and customizing kites. I have almost a year of experience with this technology, using it every day, and would like to share what I have learned with those of you who are interested in the subject. I am an engineer by profession and finding this new tool has been the realization of a dream of a lifetime... If I can sketch an idea on paper and then create a 3D model of it with software then I can hold a physical example of my idea in my hand after printing it. Many ideas can
  8. I am most of the way there! Thanks to my beloved Kaela, a Keeshond, who left this to me when she passed several years ago along with many fond memories. I throw nothing away. 😥 😀 Since I posted my question I have discovered multiple posts regarding Dog Staking both on KiteLife as well as an interview with John on "kite-and-friends" and have seen the fabulous rig that John designed as well as its evolution. Thanks for the pictures and the video from Jeremy that were recently posted. Very inspiring! link to interview here: https://www.kite-and-friends.de/internati
  9. I am interested in experimenting with Dog Stake Quadline Flying. What is the currently preferred rig for this? I have read an informative post from Paul LaMasters from several years ago with a design plan posted but the part numbers no longer seem available. I have also been looking for diamond polished SiC fishing guides that might be similar to what was used in that design but I am coming up empty. What do those of you who fly Dog Stake use? Segel
  10. Here is a blog I posted a while back regarding dynamic testing of spars along with weights and deflection information:
  11. Abrasion is a common problem with the Rev LE Vertical Tabs caused by the vertical spars or end-caps rubbing against the Dacron tabs and eventually coming in direct contact with the LE spar. The B-Pro series kites have a piece of Kevlar sewn internally to this tab which prevents this problem. But what do you do if your kite suffers damage and does not have this nice pro feature? Introducing the Kevlar Band-Aid... It is a simple idea and is probably self-explanatory but I thought I would share how I repaired the damage to my kite in case it might help you. Here is the damage t
  12. The information from these posts inspired me with ideas to create my own Nail Board. I shared my experience recently in the form of an "instructional" blog as I felt it was too lengthy to post as a reply to this topic. If you are interested in reading it, here is the link: I hope you find it useful. SF
  13. I was inspired by the information shared in recent posts regarding the existence of something called a "Nail Board" to help tie accurate "Knot Systems" such as bridles, leader lines for handles and potentially other applications. I decided that what I am about to share is too lengthy for a forum post so I have posted this as a blog instead. I hope you find it useful. SF Nail Board Instructions for Knot Tying A Nail Board consists of a “flat board” with physical markers defining the spacing between knots tied in a line for a specific purpose. “Bridles” and
  14. Thanks riffclown You have inspired me to think about your process for tying knots and designing my own jig. I will let you all know how it turns out... I will also share a picture of my jig when I am successful. I am very accurate with tying and spacing my knots under tension using a rule and marking the knot tying points but it is very tedious. And matching identical knot assemblies such as a bridle or leader requires some adjustments afterwards if there were slight errors. Perhaps the jig can make my process more consistent.
  15. Does anyone have tips for how to tie precisely spaced knots for the pigtails besides just using a rule? I have heard something about a "nail board" or some sort of fixture to tie the knots.
  16. I just discovered this place today. Several elementary schools here in the Spokane WA area were built with a similar design that included an "elements protected area" perhaps for recess activities when the weather was not all that great. The area is protected from wind on 3 sides and on top. The width of the area is ~ 25-30' and the height matches the adjacent gym and slopes off, at least double my height. I plan to enjoy flying my iflight there and then begin learning how to fly an indoor quad. Segel
  17. Hello Jeromeo and welcome to KiteLife! So you are wanting to learn about quadline kites... this is the right place to get some great advice and help. Are you learning to fly a quad now or looking for one to purchase for the first time? Enjoy exploring this website, Segel
  18. Welcome to KiteLife! There are many resources here. How is your kiting experience in Lancashire and what brought you to KiteLife? What kinds of kites do you like to fly? Best Winds, Segel
  19. Hello UrbanFly, Welcome to KiteLife! Where do you hail from? And by your username do you fly in Urban environments frequently? Regards, Segel
  20. That is very impressive to fly a dual line kite with one hand! Imagine flying one in the other hand at the same time, I bet you could do it. Regards, SF
  21. How about the "bird-cry" sound your kite makes occasionally in just the right wind conditions?
  22. 2 lbs of tension won't be enough to set your lines, you probably already know that. 2 lbs is enough to equalize your lines though once they have been set or used for a while. I should have also mentioned that step 6 (Double Check Line Length) could be performed first in order to check your lines to see if they need to be adjusted. SF
  23. "Pulling" back to the subject of line equalization... I have a very precise way to make my own line-sets. There are parts of my procedure that can also apply to "line equalization". I will summarize them here. Materials needed: ~4 feet of 1/8" shock cord 1" square of scrap Dacron or other padding material. forceps, or suitable clamp 5 tent stakes. I make and equalize my lines under tension. It is important to provide equal tension to each line. You will find that you become frustrated if you lay out four 120' lines (rough cut), grab all of them in your hand and
  24. I should have included this information in my post... Two chain washers weigh 1.7g (.06 oz). My new kite weighs 230g (8.1 oz) -> rev Mid-vent equiv with two-wrap rev rods; shock cords are not trimmed yet. The addition of two chain washers will only increase the weight of the the kite defined above by .7% I like the field-fix idea . Considering a tear as I experienced, a bottle cap washer with two holes could allow one to continue to fly; it would support the vertical displacement of the shock cord loop against the remaining Dacron and there would still be plenty o
  25. My kite was recently damaged by wind conditions that were too strong for my sail choice that day; I had become overly anxious to fly a kite that I had built this winter and had been eagerly waiting for an opportunity to fly. As a result of this mistake, the shock cord that attaches the leading edge rod to the sail, tore the Dacron tab between the two holes in which the cord passes through and is tied in a knot on the backside of the LE. I admit that this happened because of a slight design flaw in making a leading edge out of one piece of Dacron and using holes to replace the scr
