    Guys,

    This seemingly simple project took me like a month to complete ...LOL

    So I want to share the details, just in case any of you might encounter the same need.

    I got these HE pedals, damn it is so tall and its adjustment possibility if installed the normal way, is totally not comfortable for me. I got small feet, size 7 1/2... LOL.

    So I googled and found this review by MockRacer, on how he installed it on his chassis.
    http://www.mockracer.com/2014/12/he-pro-pedal-impressions.html

    But I have a problem, my chassis floor plate where a pedal base is at, is adjustable ( floor extender ) by 10cm forward/back. MockRacer chassis is simpler.

    This is how the original pedal base looks like :

    As per SimPit review/assembly:

    .
    Under the "floor extender" mechanism. So it slide the entire floor plate by 10cm and along with it the pedal base. This is a good feature, as the steering wheel position and distance to driver does not change. So long leg driver can take advantage of this. Only the seat adjustment is what make steering wheel distance and also pedal base distance changes. There is also some more minor adjustment available on the steering base, angle wise and distance wise.

    So i was thinking, I cant lock a fix distance for my pedal base, if i were to mount the HE pedal like how MockRacer did. I got a friend who is 185cm tall who will enjoy this chassis too :)

    First I work on what is the angle of comfort I need and the distance I need and what my shortest 15 years old daughter will need leg length wise as she is 10cm shorter than me. So I can't be selfish, must make sure the mod will yield a very adjustable new pedal base positioning, for various leg length and angle too.
    Damn, took me more than a week drawing sketches on what I think as most suitable adjustment mechanism.

    So I got no choice, must make new pedal base as the HE pedals for me must be installed upside down, or perhaps you guys call it top/hanging mount ?

    Original function ( adjustment by 4 bolts spacing ) of floor is to be maintained.
    So I came up with this ugly design..... LOL. This freaking thing weight like 15kg or so...

    Will continue.........

    Continue.........

    This is how the DIY pedal base looks like.... crude indeed, but I need a very rigid one as the HE pedal is 50kg force. Good thing RSeat N1 50mm tubes for the chassis is VERY stiff.
    So any mod I do, must be better or minimum as good as Rseat , strength and stiffness wise.
    I don't like chassis to move/bend or shake during use. I chosen Rseat N1 because if its 50mm pipe and also it does look good.

    .
    Now I must think of how I will design an adjustment mechanism.
    As the floor ( DIY pedal base ) move forward, its angle towards any fix position adjustment mechanism will also change. Any friends or my kids difference preference of angle for their footing to pedal vs my setting, means the adjustment mechanism must be as easy as possible to adjust.

    The stiffness I expected to get is what made me over built this DIY project, but it was worth it.

    Measuring something not permanently fixed and not having the actual object to measure was kinda tough...ha ha ha.

    Sometime drawing something and actual product use when the need for mounting bolts and nuts and other things, need imagination. So the work is very slow. Make the parts half-finsihed, test for its actual use and how I mount pedals, how the bolt/nuts can be placed, how my tool can work on it and so on.
    Since I ask a low-grade machine shop to do it, it takes a long time to complete this DIY project.
    There are things they cant fabricate accurately ... ha ha ha.

    Finally it is done, still lacking of final finishing touch, but it works well as planned/designed.
    Not the best looking add-on, but it does its job very well.
    Very stiff. No rattle. No movement. Only single tool needed for adjustment.
