Don't know Paul - You may have to fight it out with Nick. Agitators at dawn, so to speak.Tim McClure

Hmmm.............gess this means I don't even get a look in.Ignorance is bliss............but only till you realise you were.

[NiqueNaque]

Sorry Birdy...Some one has to call you a wa*ker first, you've not had that dubious honour so you're disqualified.Cheers,Nick.

Paul,How big is yours?

[asra]

Paul, I think you are on the right track with the carbon disks. I was talking to Alex a couple of days ago and he was hoping to make a contribution here.He might be put off by all the pathetic contributions on this forum. I hope he isn't as he can see what many can't bieng so experienced in the field.

Are there any details available on the initial component failure that kicked off this forum?I ask: has the failed component been in an accident?is it old? has it flown lots of hours? did it have corrosion on it of any form? has it had any forms of stress relief carried out on it? were all the holes deburred? and at which point of the bar did it fail?Has a tech officer posted a report on the accident? Prerotators may not be the cause of this failure.CheersGyro Gearloose

Dear Camel I have bolted from another forum to join in, it took me a bit to notice there were 11 more pages, hence the disjointed entry preceeding, but I dont think I have missed much content.I have been putting some thought to the subject, I think there 2 sorts of requirement , one just to get the rotor going from the security of the seat, and the other to avail an instant realm of flight with no run up. I noticed that the prewound spring has been sugested I think this bears some follow up. and maybe the need to look at teeter block design which can with stand a greate turning input force. The decision has to be reached as to weather a standard head is ok to use a prerotator on and then establish the criteria for the motor drive, perhaps we need to start thinking outside the box with simple ,light and low cost ideas.cheersGyro Gearloose

Alex,If you would like to send me your Email address I could explain a few things, My Email address is pjbarsden268@ozemail.com.au All the best Pete BarsdenPete Barsden

Gentlemen,Image Insert: 4.23 KBSubsequent to Grant's posting on teeter blocks I came up with this, use it at your own peril...Cheers,Nick Tomlin

You got a great drawing program there Nick. A question, how do you reduce the size of photos you might have in your computer that you want to reduce to under 100 kb ? I'm not all that puter literate so take it easy on me You never know how far you can go, till you get there !

Brian,Wellll.......You're most likely using micro****e, so you have a disadvantage immediately... I use Linux, so this may be difficult to explain as I don't know what micro****ware you have..The image I have captured above is a screen grab, with Linux I press the "print screen" button, and up pops a screen grabber, I select the area I want to save and save it into a .png file, end of story, the grab will tell you how big the image is, all too easy.You might try, if you have it, Adobe photo shop or the MS paint program, have a look for the 'save as' function in the file menu, save the image with about 75% resolution, see what size it ends up and then calculate the actual save resolution you need to make it fit in under 100 kb. I used to use Macromedia 'X Res', it worked like that, when you save (in a .png or .jpg file) it prompts you for the resolution you want, you could end up with as little as 16% of the original image to save it under 100kB, ie, look at the file size, if it is 600kB, make the save as resolution 100/600 = 16%.The .png and .jpg are file descriptors carried with the file, usually you will have a file name, say 'brian' which might be a mug shot of you, you save it on your machine and you see the file is actually saved as 'brian.jpg' or 'brian.png'. These extensions are instructions to the computer on what type of program it needs to use to open the file.As a guide a 1.2 megapixel digital photo shot uses about 600 kB of memory, about 6x more than you can post, so you have to cut the resolution down to about 200 kpixels, which is near to video frame size.As to the design above, I would recommend the teeter posts and bearing block to be one piece construction, as shown there is a shear plane at the bottom of the teeter posts. Make it a one piece and that issue disappears.Cheers,Nick.

Thanks Nick for that info, makes sense when you explain it like that. We are still running that microsoft thing a this stage but have changed our web browser and email to Mozilla .Not sure if we do enough serious stuff to go to Linux and having to work a new system out.Thanks again.BrianYou never know how far you can go, till you get there !
