That shifter design was a no-go. So it was redone.

The gold part is a 14" long, 1" OD aluminum suspension link tube I found on SummitRacing. The clamp that holds the gold tube was a scope mount I got from Ebay for $5 shipped. The heim is a 5/8" shank, 1/2" eye aluminum heim with misalignment spacers. And the univeral joint part was a steering shaft, also from Ebay.

ummm wow looking at the pictures i initially thought that ain't gonna work until i watched the video and see how well it does work .

nicely Done

Now that is a work of art.
I want it framed and hanging in my dining room.

Pretty amazing Prez!

Battery mount.

Front:

Back:

Located right behind the passenger's side seat (seat removed for pix) and in front of the radiator:

Battery is a Deka Intimidator AGM group 48:

Close up of the "rocker" clamp which goes over the battery handle and applies an equal amount of force over the two "pads" at the front and back of the battery. All of the rocker's plates are 3/16" thick alum. The center pivot will be replaced with a solid 1/2" alum rod (currently a tube cauz that's what I had at the time).

I like the shifter, but be careful with the scope mount. Its not designed to take any kind of side torque. As long as you have a light touch with it, it should be fine. If you are like me and slam gears, it might break.

Thanks Mr. Kennedy, will keep that in mind!

wow i cant believe i never read through this yet... just did and i want to see an overview shot!!!

Can you imagine a time lapse video of the past few years?!? That would be great. Maybe some one will take all the pics from this thread, and make a video from them, and post to youtube for us all to see!

ooOOOooo now that would be awesome...

Minor things done..

Had to redo the coolant tubes to clear the battery and finally made tabs for the hydraulic cooler:

Converted the fuel rail to -6 AN (first time TIG welding stainless). The other rail was capped off ("dead head") since the FPR will be mounted close to the fuel tank:

Mounted the electric brake booster low:

And now for the most controversial part, the hand throttle. It's modeled after Alex Zanardi's design (a quadriplegic race car driver -- CART, F1, etc..). Anyways, it's obviously not done yet but it'll sit somewhere behind the steering wheel and you pull to increase RPM. It'll become more obvious once its near completion but here's where the ring is going to sit:

The ring was made by wrapping it around an 8" baking pan - annealed with a propane torch and hand bent:

Why is the hand throttle controversial?

Why is the hand throttle controversial?

Oh cauz its been swimming in my head for weeks now, spent a ton of pages sketching a design, how to fabricate it (steel, aluminum, composites?), and I'm not 100% sure yet of the execution but I'm just going to go with this design and hope for the best. It'll also "stick" (doesnt return to idle) so it's going to interface with the transmission's neutral safety switch to kick it back to idle every time the shifter is put into Neutral.

why not get one of them springs everybody is using for the c clip eliminator dealio and use it for a return spring, ??, they don't require that much force to depress.
throttle could be on a sliding sleeve with a setup like a rotor for bmx brakes on the headset

Here is the info about that spring. At least what I got when I measured it.
Echo spring # 69621655730

Here are the #'s I got while measuring....

28 PPI
1.447 OD
1.213 ID
coil wire thickness .113

I did try a couple other springs before that echo spring and found some other ones from the center of the string head of some other weed wackers were shorter and softer. IIRC, the ones I tried at first were only 10 PPI. I might even still have them lying around if you want to try them.

...I am really digging the use of a rasp for the hand throttle...:biggthump

Sometimes I wonder if IZ is building something for space travel or off roading :scratch:

Both, what you don't know is in his other garage is the delivey vehicle for the current Mars rover we're seseing being built.

Made a fuel filler, but waiting for some parts from my brother so I only got this far:

Inside of the fuel filler - big hole for filling, with two smaller drain holes at the bottom, and three holes at the top for vent during the filling process:

Started the electronics package thingy - the computer and megasquirt. I'm also waiting for a small audio amplifier board to arrive just for some audio feedback or easy listening. The motherboard is on top (not mounted yet), hard drive on the left held by a stainless steel bracket, megasquirt sits under the motherboard, and to the right of megasquirt is the power supply for the motherboard:

Also tested out the LCD, 1500 nits of wholesome photons arriving at my face. Max native resolution is 800x600 - not bad but not great either, but it'll have to do:
