I test fitted both front and rear hubs, connected the steering arms and the system works.
It steers.

[tauruck]

I still have tweak some bits and adjust steering arm lengths but it isn't binding anywhere.

More pics of the nightmare.

[tauruck]

Last one for now.
I'm quite pleased but I guess I'll run into some issues along the way.

To change wheels the steering arms are removed, the vibration dampers unbolted
and the swing arms rotate upward unimpeded making the job less difficult.

When I eventually get some rubber?.

   Great engineering job, Mike, you never cease to amaze me. Looks like those sleepless nites have payed off.

Doug you make me blush if that's possible but thanks for the compliment.

All this stuff is about that one burnt bridge.

Worked like a mad man today. Poor neighbours if they had hangovers!!!!
Die grinder, cut off machine and angle grinder.

I only took a break to watch Brad Binder become Moto 3 world champion.
He's "Bradical".

Pics of progress tomorrow hopefully.
Shower coming up and off to bed.

Looks like sound eng. /fab work Mike....with a tandem set-up, do the wheels steer at different ratios/arcs ?

[tauruck]

Jerry I think it will all work as required when we do the set up.
The system is so adjustable it scares me. I'm used to setting up
a Formula car with 4 wheels but this tandem steer is all new to me.
I have to be honest when I say I copied a lot of the Speed Demon's
front end. Who better to imitate?.

I get good advice here on the forum so I think I'll be OK.

Got pics of the rear end stuff to upload later.

I got sent some pics by a guy that's a fan of F2/F Atlantic.
These photos brought back memories.
I still think I should have stuck with my original helmet paint scheme.

A while back I was complaining about not being able to find suitable tig cups.
I persisted and I think it took about two months but I found what I what i was
looking for. R22.50 each and in $$ it's about 1.50.

My sponsor at Air Liquide put me onto a company nearby and a very nice
lady called Janine had the product waiting when I arrived. I wanted to kiss
her but she's got the flu!!!. Seriously, when I called to thank her she'd already
gone home. Sick as a dog.

The new cups work well and I finished the mounting brackets in no time.
Good tools do make you a better worker.

[tauruck]

The heavy duty brackets will be welded to the rear end plates tomorrow.
These are for controlling the sideways movement. Long way to go but I
think it will work out.

I have a brand new tube notcher that bolts to the drill press bed
but my Fong Cong inherited drill press is so "pap" (a South African term for weak or soft)
it can't even scratch the surface of a tube so I built the whole chassis using the press with
hole saws directly off the collett. Time consuming as even the slightest pressure stops the machine.
The motor is .75Kw.

I'm almost finished with all the notching but I was thinking of building a stand alone rig to use in the
future. I know I need a motor (220v) with big power but slow speed. What I don't know is what
speed the hole saw should run at. Any advice??. Thanks guys.

Busy on the 2 reverse triangles that make up the side to side stabilizers.
One on top and one under the the rear end.

A while back the local genius down the road pulled the plug on me
doing a 40 grand jig for a dock leveling job because he thought my
use of the drill press was suspect because he saw me "picking"
while drilling a hole in a difficult material on a weird angle.
The dude owns a few machines like a mill, lathe and 3 axis CNC
unit.

I think the attachments prove he doesn't have a clue.

The notching was done on the El Cheapo drill press.

[tauruck]

AND I made a few mistakes on measuring twice and cutting once!!!

No biggie and I've had to fix many of my screw ups on the build in the past.
The side tubes were from old mistakes but I'll remove the threaded bushings
and notch the tubes accordingly. The main tube was cut too long by about
2". It will all work out and I have a good jig plate (12mm) so I'm
hoping for some success.

I drove 80 miles to my "wheel builder". That's 40 each way. Been chatting to the guy for 2 months on the phone
and the story was he was moving the operation to the new factory. I called yesterday to inform him I would
be coming over. No problem he says.
I get there today and it turns out he never built the wheels. He jobbed it out. Why couldn't he have told me before?.
Anyway I get to meet the real guy whose almost as far tomorrow. I wanted the current guy to send the wheels to his specialist but
he said it would be cheaper to deal direct.

2 months wasted but things work out for a reason. We did check the first wheel and it's as good as it gets. 7 to go.
That's the report from roller coaster central for now.
