zombie pedal: dead pedal with a shaker
Migrating from heavily modified G29 pedals to PT2 was less than game-changing
- adding a heel-toe throttle pedal helped
- eliminating brake load cell lost motion also helped
- eventual conclusion: a dead pedal was wanted,
having always used one on track to help anchor butt in seat
- dead pedal is a good place to add engine vibration
Assetto Corsa, VR and tactile feedback
My first tactile experience was clicking into Assetto Corsa's E30 M3 Evo
wearing a Samsung Odyssey WMR headset.
- The SRS ShakeSeat suddenly came alive,
strongly evocative of real E30 M3 track car experience.
- Sadly, engine vibrations confound more useful haptic feedback:
tire slip.
- Useful beats immersion, for me,
but dead pedal engine vibration need not be distracting.
- While a dead pedal deflection from foot pressure is unwanted,
lateral deflection for haptics is fine.
fabrication details
For squaring the carriage bolt to to its mounting surface,
a parallel fender washer is wanted for sandwiching.
- match a hole saw to the fender washer o.d.
- clamp the dead pedal to the drill press table,
so that hole saw cuts will be concentric with the carriage bolt hole
- run the hole saw down until it barely touches the lowest web
- we now know how deep to trim for 4 points of parallel fender washer contact
- trimmed
- fender washer should be concentric to the carriage bolt hole and parallel to that surface
- file holes square to engage carriage bolt
- Space exciter to clear dead pedal webbing.
Compress split lock washer with first nut
then jam with second nut; add spacing to taste
Locate carriage bolt hole so that foot will not contact the shaker.
Fabricated dead pedal bracket is clearanced for rigid dead pedal engagement.
>Neoprene pad between bracket and pedal base can be resized to tune lateral shaking
- ready to mount
