i had the same the same thought with my track car.
that the servo is a known failure point and i didn't want to trust my life on it haha.
also, if we did something similiar to the one in the original post it would have fouled on my Dellorto's
so, behold our next creation!
im not going to tell you what it is....
we started with some CAD/CAE (cardboard aided design/engineering)
then this....
....with bits cut out...
a few bends...
...welded....
oh dear, a HOLE!
can you tell what it is yet? (sorry about the 'joke')
hole drilled in brake pedal and bush thingy inserted
pedal reinforced
assembled. you should be able to guess what it is by now.....
tadaaa!
and there we have it, a dolomite with an inbuilt bias pedal box......what do you think?
