Paul,
       Do you have any further info or photos on the Bell gearbox Dave Lemon
   will be using for the time to climb record attempt and I would
   appreciate any
   info and/or photos you may have on Dave Garners Bell gearboxes he built
   for his Turbo 12A engines on his twin.........

   Thanks,
   Kelly Troyer

   Not Dave Lemon. Jim Mederer of Racing Beat.

   Dave Garner is dead.

   Jim Mederer did the bell GB adaptations on Dave Garner's huff and puff
   back in 1973.

   I have tons. Here are some.

     I stand corrected !!..........I am interested in any
   further info or photos you have about converting the Bell
   47 box for our use on the rotary........I had some photos
   from discussions in years past and have a rudimentary grasp
   of what Bell 47 parts are needed and I have a Bell 47
   maintenance manual with transmission parts breakdown and
   part numbers but would appreciate any more info you can
   supply........The output shaft to the prop is a particular
   unknown to me as to if it utilizes some reworked Bell 47
   parts or if it was totally purpose made.........If you
   would rather not clutter up the group please E mail me
   directly........

     Curious If Jim Mederer is currently using the same basic
   box he designed for Dave Garner's Twin ??..........


   Thanks for any help and all your work on behalf of the Rotary Group,

   Happy Holidays,

   Kelly Troyer

   The front of the box has been redesigned for the time to climb engine.
   I don't have dwg's  in case you ask.

   Here are a bunch of pictures.

   Paul,



     Thanks a bunch for the photos of Jim's new Bell 47 based box.......What a machining work of art (spelled $$$)........I am presuming
   that the housing extension is to allow for a resonance dampening system that the original Garner box did not have as the planetary
   sun drive gear was bolted directly to the 12A counterweight (unless I am seeing wrong)........Is my assumption correct ??......Do you
   have any additional photos of this resonance system by chance and was the lack of this system considered a major fault with the
   Garner box for normal use or considered a necessity for the power levels needed for the time-to-climb engine ??.............

    Would appreciate any old or new info you have or obtain concerning Jim's new box and how the project is progressing........

   Thanks Again,



   Kelly Troyer

   No. It is direct connect. The design life is just a few minutes.
   Rubber couplings mitigate the shock load on the gears.
   Not just for torsional damping.
