Re: tracks from tires

Joe,
  I reference to mounting guide horns on the inside of a mountain bike tire. I say 
that an in-depth study of glues would be in order. There are some incredible ones 
out there. Blue RTV silicon is very nice though probably a bit too flexible. CA glue 
is too brittle. I would check on stuff like Gorilla Glue I have used it on various 
things and found it to be incredibly strong. It is activated by a tiny amount of 
moisture and expand 3 times its initial size to fill small gaps. It must be clamped 
though to attain full strength.

Chunks of tire could work well for external
cleats on TTS.  However, the tire carcass
is much too thick to make a track by itself.

In addition to trying snow mobile track and
snow blower track, I also tried mountain bike
knobby tires.  I got a couple discards from
my local bike shop and slit the steel beads
away from the sidewalls with a Stanley knife
(Be very, very careful if you try this.)

When I flattened the tire carcass, it was close
to the circumference needed for a tank.

I mounted the carcass around two 5 inch DIA
wheels suitably spaced on steel shafts in a
2x4 frame.  I then pulled this "track" around
the wheels manually to get a feel for the
motor torque that would be required.

Although I believe that our motors could
turn this "track", I had a terrible time with
tracking on the wheels.  This "track" constantly
wandered laterally and it was difficult to prevent
it from throwing.

If anyone can devise a way to mount guide
horns on the inside wall of a mountain bike
tire carcass, it could provide a nice flexible
rubber track with great grip.  However, I could
not get anything to stick very well to my tires.

Give it a try,
Joe
