The order page for the PVC blades is up and going, and Anthony is ready to take orders. I wont post a link from the main site just yet, will let you regular forum readers place orders first to see if there are any problems. http://www.thebackshed.com/windmill/PVCBladeOrders.asp Any comments please let me know.

Glenn, Thanks for the work done here. Pls let me know what sort of a blade length would be required for a cogging 0.75 wire size stator? At the moment I am experimenting with a 3m dia. prop and two blades and have the assurance it will start the cogging F&P from the shortest testing tower possible. Just in case I win lottery, when do you think you will have the laser-cut mounts for sale and what sort of a cost are we looking at? So many questions, so little time!

Hi Dom I'm looking at a few options. 1. Waterjet/laser cut parts to my design, from 6mm mild steel, will cost about $140 ex GST, plus the U-bolts and delivery. 2. I'm going to see Trev next week to discuss a cast alloy hub to suit the 25mm blade mounting rod. A cross between his existing F&P turbine hub and his aircraft propeller hub. 3. Draw up a design that could be made from common steel sections 4. Make the CAD files for option 1 available on the web site, so anyone with access to a laser/waterjet cutter could get the parts made themselves. If Trev can come up with a hub, then I think that would be the way to go. All options will allow easy adjustment of the blade angle and either CW or CWW rotation.

Has anyone got any suggestions on a good ( cheap ) way to transport these blades. I managed to post one set to Phill, 1000km away, and it only cost about $12, the parcel was 1350mm long, 180 wide and 100 high, weight was about 5kg. Now Australia Post is telling Anthony they wont post anything over 1050mm long, so I think I was just lucky to slip my parcel through the system unnoticed. Poor old Anthony has spent days chasing quotes from all over trying to get the best price. So has anyone go any idea's on how we can send these blades around the country, and over sea's, at minimal cost. Weight is minimal, its the length thats the problem. Courier companies are asking way way too much compared to the $12 I paid. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

I know aus post will allow parcells over 1050mm as you can ship golf clubs no worries , but sometimes they winge because it stuffs up their shipping crates . I think it depends on who you get on the day and what mood they are in...

Hi Gizmo, I have FEDEX rolling poles for painting that are over 12' or 3 meters, for 16 U.S. dollars. How much are they asking to ship the blades? If your not living on the edge your taking up to much space! |

Also have you inquired about shipping them freight because here it's cheaper sometimes. If your not living on the edge your taking up to much space! |

Glenn, As has been suggested before, why not ask Trev when you see him is he is interested in casting/machining a Jacobs-like variable-pitch hub. The one-inch tube could rotate inside another tube or hub with a spiralling cut, where the inner tube is rotated once the centrifugal force tries to slide the spring-loaded blade outwards. A slider attached to the blade tube would follow the spiral and rotate the blade into coarser pitch at higher wind speeds right up to feathering.

Dom, The twisting is not the problem, it's the synchronising that matters. If Trev were to do something with this idea, it would be far more productive to build/cast the spider and matching blade holders.... just leave the outer to rotate and slide on the inner rod (maybe 500mm long). Use the spider and the blade gripping thinggy (and ball joints), to control the twist and synchro problems.... would be a beautiful setup. In my humble opinion, this would make these blades a must have for those wanting a good reliable idiot proof variable pitch...... M. Jacobs knew his stuff. .........oztules Village idiot...or... just another hack out of his depth |

Oztules, An aside: Did you by any chance read a short article about Flinders Island in the recent Review section of "The Weekend Australian"? If you are interested I will give you the date. If I remember right, then the ferries name is "Mathew Flinders", etc. Taxation as a means of achieving prosperity is like a man standing inside a bucket trying to lift himself up. Winston Churchill |

Regarding freight, at least within Australia, then using the bus freight system I believe would be cheaper and they would not worry much re the length. They do carry lots of lengthy items such as surfboards, fishing rods, bikes etc. Three blades in bubble wrap would be a very secure package setup and not likely to damage them. re the variable pitch am thinking a heavy coil spring in tension holding the blade at an 8+- degree pitch with adjustment and as wind increases blade rotates tension spring into higher pitch until finally feathering. Tension spring will be fitted to end of 25mm SS and MS internal shaft and locked between the ferrule on hub and washer and nut on end as per Anthony's hub setup. Ferrules may have to be a little longer and would be lubricated so as to move. Springs can be wound and shaped in MS and heat treated to correct tension. No problem....

All joking aside, has anyone inquired into the cost of shipping the blades to the U.S.? If so could you tell me what the price is? Or will it be cheaper to swim over and ride them home like a raft? If your not living on the edge your taking up to much space! |

Hi David Use the PVC Blade Order/Inquiry page. http://www.thebackshed.com/windmill/PVCBladeOrders.asp. That will send your delivery address to Anthony and he will get back to you with a delivery cost. Its then up to you if you want to go ahead and order the blades. If you can keep you blade length to 1m ( 3'3" ) then he can post them, a lot cheaper. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

Has anyone come up with any better methods to ship these? I am stateside and I just got a quote of $84.90 AUD ($60.49 USD) to Airmail to Texas. That's more than the cost of the 3 one meter blades!!

$64US + $75AUS for a set of blades to be sent to Texas , thats $42 a blade , to me I would think that is a good price over building a set of blades . Freight costs are a part of the over all cost....

Within Australia Greyhound freight quote from Melbourne depot to Hervey Bay Queensland is approx. $31 for 1500x180x100 @ 6kg. That is just over 1500kms. Seems it would be much cheaper than most courier services.
