12" over front end

[ROADKILL]

Well I have run out of popcorn and feel this one is heading down a dead end. If bigjohn can post pics of 13" tubes and not of his own Raider, I am canceling my subscription to this thread and will move on to other exciting threads... 

I still say having the joint under the tree is a bad idea, thats all I got for this one. Adios!

Probably not quite at center.  I have the 3" and only about 2" are visible.  The first inch is buried in the upper tree.
He said that the joint was going to be flush with the top of the bottom tree-not below it- the rest was going to be above the top tree. At least that was my understanding

Still seems too close for my comfort.  I wouldn't do it.

I don't think the factory upper tubes were designed to have that much more stress put on them either, but then again, I've got 4" ones.  I wish him luck and can't wait to see pics.  And I truely hope that it ends up safely, with no issue.

Ron-where does the joint end up at using the 4" ext-about half way in between the triple trees?

Dan The seam ia a little below the center point of the upper and lower triple tree.

Is it really?  I have mine covered, but I figured it wouldn't be that low. 

Sorry. Giving false info.

On one of his other posts he said the was going to move the stock tubes down to just above the top of the lower triple tree without an extension and ride the bike...to prove it is safe to add a 12" extension.
I measured the distance between the top of the upper tree to the top of the lower tree = 11", so with his 13" ext with 2" above the top tree - thats if he puts the joint flush with the top of the lower tree.

So if he has the threads clamped in the bottom triple tree wouldnt that actually make the joint more rigid than if its between the triple trees? I dont know Im no engineer

Reverse mine, it's a little above, not below the center point.

Isn't that what I said in the first place?  Not quite at center.

I wouldn't think so because I think there would be more stress right at the lower tree, but I engineer software, not mechanical parts, so I could be all wrong as well. I guess I'm thinking when puting a nail into a stud it's going to be stronger the deeper it goes in instead of just teetering at the point.

Well no, you asked, I answered and reveresed my answer when I realized I had it backwards.

[Scoob]

Actually I asked

[Ron505]

Whose on first......   

[Ares X]

Actually I asked

I was going to argue that, but I figured I'd just let it go.  It's easier.

  Still no picture of a Raider  .. Some random metal tubeing . He may of just went got some pipe to fix something at the house.  I have a feeling these (bigjon) threads are total smoke to waiste our timelike the dang windshield i was going to buy from him that i dont think he really did have .

[bigjohn]

those extentions you see are  not random metal. they are an alloy. if you would like me to get you the content of the aluminum used to make those extensions [so you can take it to your metalurgist for testing] i would be more that happy to. and i will send you a free sample.  when you find out it's stronger that the chinjap aluminum in your raider wheels you can buy me a new 8.5 wheel for the back of my invisible raider. deal? why should i post pics? to hear negative and derogatory comments about my ride? oh, but i will post pics [when i'm done] just for the guys that appreciate some one who has the stones to try something no one has ever done. i mean how many raiders rode by your house today with 12" fork extensions? and as for being thin skinned, you would be correct. i know people, nuff said there.  i better slow down on my posts. somebody gave me a time out when i used the word "xxxxx". i was only refering to all the cats that claw and scratch to get a ride on my raider. i like all the attention all the time, anyone else in the same boat? oh yea i better say that i used 3m #2 and #3 by hand on those extensions last night and they are shinier than ever. just ordered a phase 7 light and some more chrome. make some more popcorn the movie's just getting started. big john

Mr. T... Once again I removed the derogatory word regarding a part of the female anatomy.

I'm with ya 

asked a few times for just update pics to see what bigjohn was doing ... hasn't happened.
all I've seen is talk about extensions ... church ... and bj telling us how some might now say what they say if they saw him in person

I wish you well with whatever is it you are doing

[silverstreak]

i have been refraining from posting on here but i will add my thought to the extensions.

It is a wicked concept and aside from being a static display of a raider with such long extensions with its threaded fork joint being bound by the lower tree, it wont last the road torture.

ultimately you have eliminated the upper tree from doing its job of stabilizing the forks from torsional load.

smaller fork extensions get away with this as they utilize 3 points of torsional resistance. Upper tree, threaded joint and lower tree. Having the joint in the lower tree leaves you with one torsional resistance point, you might as well just drive with the forks bound in the lower tree alone.

no matter how strong the threads are, given how few there are, the fulcrum torsion stress on that joint will sheer the threads out of the forks or off the extension thus rendering a collapse and hopefully not death.  the triples are not made to endure torsional stress that will be applied by the geometry of the forks in relation to the frame being pushed out that far with the joint where it is, add the weight of bike and rider, then the road irregularities it wont last long. Unless you have a trick up your sleeve to strengthen the joint and the fork assembly as a whole?  I wish you best and i will stand corrected if this does work and you dont crash from fork failure.

I think, and this is my and only my opion, I would like to see a pic of YOUR Raider, with the tubes held beside the trees, since, You can't seem to get them installed, something does not smell right here.....just MY opion......

[michael t]

 Someone send me a PM.   WHEN THEIR A PICTURE   At least bill kept us posted with pictures as we waited for his bike to be finished.
