The shop just got a bit more crowded.

And so much for retirement. I'm now a member of the fab team at Orbis. Only part time. Check out the 4-wheel drive Civic Type R hybrid. This really is pretty cool stuff. We just got back from a successful week at SEMA, showing off the Civic.

https://orbisdriven.com/

so - this Lotus 7 replica is going to be converted to a 200 hp, 4-wheel drive electric vehicle via installation of Orbis wheels at each corner.

This will be a great learning experience.

Will 2 of these wheel show up on the front of my 914? 430 hp to the rear wheels and 100 to the fronts? (IMG:style_emoticons/default/idea.gif) What could possibly go wrong?

I know, right? Never thought anyone would pay me to fab (my yard art stuff aside).

It was a major milestone. I did my first "paid for welding" to help prep the trailer to take the Civic to SEMA.
No Olympic Welding Team for me...!

Congrats Chris, that is awesome! (IMG:style_emoticons/default/piratenanner.gif) We’ll be seeing you in F1 next!
Yes I see some of that tech in your build. (IMG:style_emoticons/default/happy11.gif)

take one perfectly good wheel and completely reinvent it.

It sounds right down your road, Chris.

Enjoy the ride. However, us hangers-ons will be be needing regular 914 LS fixes... Just sos you know... (IMG:style_emoticons/default/sawzall-smiley.gif) (IMG:style_emoticons/default/welder.gif) (IMG:style_emoticons/default/stirthepot.gif) (IMG:style_emoticons/default/pray.gif)

Awesome!!!!! Congrats on the fun gig!

I've been thinking of ways to power the front wheels via an electric motor for a while now. 100hp is just about right to make things interesting!

So the teener will be delayed a bit more (too funny). As stated you are the "right man for the job!". I am glad this came to fruition for you Chris. Regarding the wheel: Do you think they will be able to get that "hum" out of the system? The demo alone is enough to drive me off/crazy.

Congrats on the new gig.

Neat idea, been tried a few times, this might be the right time with materials and tech being much better now.

Cool deal! Sounds like fun! (IMG:style_emoticons/default/smile.gif)

The exposed bearing wheels and gear kinda sketch me out for a production application, but still neat. Most modern attempts at the fixed center automotive wheel I've seen use something like a Franke wire race bearing. Not really sure what it buys you over a hub motor with planetery gearbox and rim mounted brake rotor (for clearance) though.

Yes congratulation Chris, well earned.

Enjoy the venture capital ride. So while your in this game I will give you the advice I found out early in my career, you have two bags. One is for money they will pay you for your talents, and ideas. The other is for all (IMG:style_emoticons/default/stromberg.gif) that comes with the work. When ever either bag gets full it is time to leave the game.

I saw the exhibit at SEMA but didn't know that you were involved - as a former Honda tech, it was interesting to see how technology can improve even a new platform. It would've been good to meet you there....congratulations on moving to the next phase of fabrication engineering!

Back to the fire wall. The never ending fire wall.

And it's got me to thinking: Are they called "mad skills" because developing them is infuriating? (IMG:style_emoticons/default/laugh.gif)

Note that I'm in no way claiming I have them, and let me just prove that right now.

The latest effort is to fab the upper "cap" of the fire wall dog house. Again, if only I'd paid more attention in Geometry class.

It went something like this:
- Figure out how much clearance is needed inside the dog house and be sure it doesn't interfere with the seats on the outside surfaces. This determines the plane that makes up the sides of the dog house.
- Calculate all the angles needed to connect everything. Everything being the sides, the angles they join the main fire wall panels behind the seats, the angle those main panels intersect with the remaining upper section of the stock fire wall.
Work out the angles for this upper "cap", which has to serve as the part that connects and locates most of these pieces.
- Oh, and then be sure there's a nice step around the opening for the removeable panel.


How hard can this be? (IMG:style_emoticons/default/idea.gif)

Protractors and levels and a laser that projects a line and lots, lots of measuring.
I wanted do more bending than welding so I tried to work out how I could fold things and ended up with this pattern design.

Bender! Such fun trying to work out the bend order so things don't end up interfering with secondary operations...

Can you believe I got it wrong the first time? (IMG:style_emoticons/default/blink.gif)

Fail #1

And don't bother counting, I'll total it up for you at the end...!

Wait, this looks out of order. There are no bends in this piece!
I determined I had to add the step BEFORE any bending.

Add a couple fails ahead of this BFO.

Sorry. BFO = Blinding Flash of the Obvious.

So, add the beads, then do the folding. Actually, it worked out that I had to add one bead, then fold up the sides, then add the bead to the side sections. Failed there the first time I got to that point.

Oh, you didn't know that when you fold at other than a 90 degree angle, the bead on the adjoining surface needs to be set at a different dimension?

You do now!

And I think I did to, as I posted about this earlier. But, I forgot.

A couple fails here as I remembered then worked this out...

And finally. All nice and lined up on both corners!
Now to mess it up welding those open corners. (IMG:style_emoticons/default/huh.gif)
