Default time to renew my rig

Over the last 24 it has become clear that I need to renew my driving rig. I was putting in some better computer tech, but while doing so I realised a couple of things

1) it is nine years old.....
2) the Cobra racing seat I used is absolutely knackered, all the padding is gone and it now feels like sitting on iron rods
3) it is way too big, like twice the size it needs to be
4) the G25 wheel has a lot of side to side and up and down slop, so I think that the bearing at the top end is either loose or worn
5) the control panel at the front is largely useless due to changes made over the years
6) the buttons on the front stick due to using crap quality ones
7) the attachment of the mini keyboard ended up breaking it so now it's useless
8) I look at some of the design choices and construction and mentally do a facepalm
9) the wiring to the Leo Bodnar controllers is embarrassingly bad, and probably a fire hazard too

I could go on, but I think you can see that I am pretty much convinced that I need to start again. One issue will be the main structure, that was made from welded steel tubing and cannot be changed, which means either starting completely from scratch or working around that. Not sure which way I will go yet. Working from scratch will be difficult, I don't have my TiG welder with me here (stupid decision not to bring it) so a new design will have to use different construction techniques.

I made my own pedals and using hall effect sensors plus some varying strengths of rubber foam made them work really well, at least for most games - rF2 was an exception, but not sure whether that is the pedal's fault or something else. I will probably keep those.

I have a double H pattern 'gearbox' that frankly works brilliantly in all but one respect - the side to side movement is too loose and could benefit from having some R/C car dampers attached to give a little weight to it. However that change can't be done without a complete manufacture, so back to the machine shop for those. I works so well in fact that I would not consider buying anything, as (loose side to side movement aside) I have never come across better.

The new computech parts I have are perfectly adequate for a racing sim, however how they are fitted into the rig will be one of the biggest changes. By incorporating the PC differently I think 50% of the size issues will be addressed in one go.

The peripheral construction is also going to be a major change, I can use better materials and also package better all the components that led to the current one being so big, and use modern connections and parts to make the electrics better and tidier.

The last question mark then is the wheel, and this is where I would invite suggestions and comments. I only need a wheel, so what wheel(s) would be the current suggestions for use? I do like FFB, if it is correctly controlled and calibrated, and one that has more than 360 deg movement would be preferred, if not essential

Any suggestions as to other bits and bobs welcome, as you may know of some bit of kit I have not considered

Cheers

Les

One thing I think would look cool is make wiring looms for everything routing through the frame, use rubber grommets to seal the holes , you could put USB , mic plugs .... everything

I like the ideas Durge - never thought about making it open frame, certainly opens up possibilities

I am taking the plunge and getting a 3D printer. That opens up a myriad of possibilities for the parts so will be able to make better components (hopefully)

It also brings the possibility of remaking the G25 head bearing, maybe? Perhaps moving the housing further back and using an extension shaft. Might be better than replacing it

The gearbox will be easy to do too, I can copy my aluminium one and add the coil over shock units

will be back with more ideas and hopefully photos

Another silly idea ................I never liked all the black cables everywhere.

If you don't use loom you can get nice USB and other leads that look like braided hoses in different shades.

Even ones that light up for Lemans lol p http://www.ebay.com.au/bhp/led-usb-cable

Use those skinny stainless steel cable ties to strap would look the part

That sounds extremely exciting.
A few years back I bought a T500 converter from Derek Speare to be able to use a SRW-S1 wheel on a T500 base.
And examening the converter I concluded that Derek use some kind of 3D printer to produce those small production numbers.

Hehe maybe I should make a note with your name for the next time I want some prototype created

Again, good ideas Durge

Been busy designing, and I have the CAD renders of the double H gearbox but this pesky site won't let me post the photos on the gallery - it keeps asking me to select a category, but the drop down list doesn't work

Got it to work, hopefully you can see the 3D render of the gearbox assembly

Can you put something for size reference beside it.

Here you go Durge, iPhone 6 for comparison

Thanks looks smaller then I thought.

I was imagining the gearstick was 2 feet long

lmao lol

It's pretty small, and I could miniaturise it more, but don't think there's any point. I'm waiting for some microswitches and inserts to arrive to complete it

In the meantime I'm working on designing a F1 style wheel and sequential shift
