hi

well ive been busy lately making some new pedals.

nearly all alloy construction using 30x30 and 20x20 framing as well as 6mm alloy channel.

the pedal arms are steel tubing and are pivoted on ball bearings so ultra smooth and should last a while,easy enough to replace too.

using a 'sam' sensor and festo cylinder 2/3rd's full of silicone oil to give a nice hard feel to the brake.

the pedal faces can slide up and down about 10mm to suit.

the alloy channel can slide sideways too to get the right gap for whether you left foot brake like me or heel and toe,you can get the pedals just about touching if needed,


the rake of the pedals can be altered to by tilting the whole sub frame by loosening 4 bolts.

i have also added number stickers on the frame to aid in lining up the height and sideways pedal location.

the cylinder anchor points can also slide up and down on the pedal arm as well as on the frame itself giving just about limitless settings.

anyways,enjoy pics while i break out the soldering iron:)

I guess that you are a hardware ingeniere?sadly I don't have the capacity and the sapience to make some thing like that:(I have the tools and my friend works on an alluminium factory and they have the laser machine but like said I don't have the knowledge to make some thing like that!
Can I ask you the total cost of the project?
 
thanks guys

yes very heavy duty..i think you could stand ontop of them easy.

the cost of materials was just over £400 because i wanted the best i could get for the money,the alloy was a big chunk of money :(

sadly i wont be keeping them as i need a new wheel and monitor..always something needs money!!
 
Hi it's looking very nice!
I' m serching some good pedals concepts to build my own. Are you still using those? What you can say about tham after few months? How do you like pressure brake?

And few technical qustions (If you will be so kind):
1)Which pressure sensor did you use, (can you give me a link?) How big is the pressure range of the sensor?
2) Which festo cylinder did you use in your construction?
