Focus O ring Pipe mount

[Ron Lockhart]

That's the system I've had on a Focus for two seasons.   I see Ed used three sets of O rings.
I used only the rear two sets.  I'm using an OS 1.40 with a modified version of the Piedmont soft mount,
which does't allow much movement.   I use tie wraps around pipe to provide a mount for the O rings,
though I suppose an O ring could be used there too.

Later, Ron Lockhart

  Here's the requested pics on RCU.  Yeah, the bottom is starting to look a little ratty.  Time for a repaint of that pipe tunnel. Anyway, nothing else holds the pipe, it's completely suspended from the O-Rings.  My local Midas shop would be proud.

    Bob:

    Should work fine.  I've been using an O-ring mounting method since seeing this on Ron Lockhart and Rick Wallace's Focus's.  It winds up being similar to what you have inasmuch as it allows plenty of give in all required axis, but definitely doesnt let things flop around.  Light & cheap too.  

     

    Basically, the pipe is just captured with 2 - 3 O-rings slung between whatever you want to use to pull them taught along either side of the pipe in 2 - 3 separate locations along its length.  On a Focus, it's real easy, since you just loop the O-ring under the screw heads that hold the pipe belly pan to the fuselage.  The only other thing needed is something to prevent the pipe from slipping aft.  I think Rick made some kind of collar around the inlet area for it to grab.  Depends on the pipe location, you can also suspend the last one in the back by twisting around the exhaust exit and accomplish the same thing.   I have pics of the Focus II if anyone is interested.

      In typical "MacGyver"-ish fashion I *think* I've addressed this pipe mounting challenge on the Icepoint.

      Your opinions - thoughts - should I even try this, or has someone already BTDT and learned something?

      Feedback welcomed, please!
