Thanks for your thoughts and calculations.  I do plan to get new gears and
other parts tested and I'll keep everyone informed.

Thanks Doug - this is all good stuff, and is of particular interest to me.
As soon as I get my other computer back on track ( again) I will send you an
update listing of planetary ratios that I have put together.
I have had preliminary dealings with a local gear cutter and we come up with
a design but I hadn't got to the stage of getting anything cut as yet,
perhaps with dimensions available from the Bell, it may be time to look at
it again.
BTW There are a range of materials for gears of this type and you may be
surprised at what you find - I certainly was!

Yes I would like to hear about my options for gear materials because I
suspect I will have to make the planetary gears over.

I had  the gear box taken apart and displayed on my workbench and ready for
a picture but then Murphy struck.  The 'new' batteries I bought in the local
shop earlier turned out to dead:)  I did count the sun and plant gear teeth
though.  They are 46 and 23 respectively.  The gears are thinner than I
first thought 1 inch or 25.4mm. Tooth height from the valley to the mountain
top is about 6mm or more lightly 1/4 inch.


I'll try picts. again on Monday as I am now off on a date with my wife to go
to Kyoto. We will no doubt look at falling leaves with thousands of other
people, drink green tea and ponder on the ways of the world.

Wish I was up there flying again.

Kyoto is a beautiful city. Here are a few pictures.
Sounds like Japan is getting old :)
A little home sick are you? :)

Okay Paul what is Robin saying in the road ? Maybe she should
answer :)
