Fredrik,

Thank you for your input.  I will, of course, consider all options and
suggestions at this point.    Among other things cost is a major
factor.  This is turning into an expensive toy..and I am on a simple
retirement plan that does not leave a lot of money to play with...

In addition to the drill motors...there are other gears and chains to
buy, as well, for the drive assembly...and until I look into it..Im at a
loss....I have most of my design figured out for materials and
costs...changing over might delay me even more....

But...I am taking what you are saying very seriously and under
advisement.

The other thing I am keeping in mind....is that speed is fine..for open
road...but you dont really have to move fast out of a shot, as long as
you move.... and perhaps not even have to move very far, for a hit to be
a miss....

The long and short of it is...I just have to see results that others are
getting and weigh that against my money availability.  I would rather be
a little slower than eveyone else..and be able to participate...than to
try and spend more money that I have.
