My apologies to those who missed the site over the last couple of days.
Everything should be functioning well now. If not, please let me know. Of course, if it's not working for you, you won't be able to read this.

A good portion of the weekend was spent painting someone else's house.
And working on organising the garage. I'm doing the cleanup that is overdue from the build and installing a new air compressor. It's a lot of work but this will make it easier to finish the next few stages. I did pick up the 'glass I need for the fender repair though...

Lester Seal has added some new pictures of his car to his website.
There's some nice work there on the interior panelling, it makes my car look very amateurish!

Finally, an update with more than just fluff about my garage!
I took a good look at the fender tonight and tried to clean off the bedliner as much as possible. I realised that the paint was damaged enough that this will never be a show piece. I also realised that I could make a nicely functional repair with some well-placed aluminum plates. It may even end up being a stronger setup than it was before. I'll rivet the plates to the inside of the fender. One repair that will probably only work with some metal reinforcement will be reshaping the area right behind the rock guard on the front. It's caved in with surprisingly little damage to the paint, but it seems to have decided it likes its new shape better than the old. A simple solution there would be a thin steel brace to push it back out.
Does this sound as if I'm simply taking shortcuts? Well, partially. I'm still considering a set of aluminum fenders. I'm also hoping that making the Seven mobile again will prompt me to start working on other items such as possibly a front suspension. Mark Rivera provided me with some 3D models of a Hyabusa linkage that should actually do the trick quite nicely, with angles that look pretty appropriate. I'll drop it into the crude suspension model and see what happens.

There used to be a mounting hole here.

One simple, non-fibreglass solution.
A plate to spread the load of the bolts. This will be riveted to the inside of the fender.

I have a Hayabusa linkage on the way.
This will let me play with it and get a good mental image to go along with the digital ones. I sort of won it by accident on eBay.

The grille (thanks again Chris!
) fits perfectly in the nose. I'm considering painting a black band around the nose to hide the paint damage. This would be temporary until I could repaint the whole car.

One of my worst fears came true yesterday.
A major error was found in the book. It's in the section about "Understanding hydraulics" and not only did I make one mistake with cascading consequences in the numerical calculations that followed, I also was sloppy with force vs pressure units. The latter is something that really only the physics geeks will find disturbing but the former could lead to some pretty weak braking systems. I've put a corrected version online. Sigh.
In happier news, the car is now sitting on its own front wheels again. Is it because I needed the jackstands for the Mini? Well, yes. But once I bolt that rear fender back in to place I'll actually drive the car for a bit. The Hayabusa shock linkage will be here in a few days and then the real experimentation begins.

The Hayabusa linkage is here.
It's a nice piece - but I forgot that it was designed for a shock with a clevis (is that the right term?) instead of a round bushing. I might alter the shock (yikes) or try a couple of other options. I'm also going to try cutting my existing hood and turning the louvres around. It's a cheat but it might work. Rivet lines around the panels in the hood will be less embarassing than having backward louvres.
Car and Driver is going to be doing an article on Locosts. If you happen to have one and are able to make it to the Southwest Se7ens Festival taking place in Texas in late April, please let me know! I'll be at the event as a guest speaker.

A Hayabusa shock linkage.
Will it work on the Seven?

February 27, 2006:
Guess what? Actual progress is being made!
The Seven is alive again.
Once I took the time to start drilling and riveting, the fender repair ended up far better than I had hoped. There's almost no sign of damage now that the part is back on the car. My aluminum plates are hidden in the dark wheel wells and painted black, and only a couple of rivet heads are visible at the bottom of the leading edge of the fender if you know where to look. In fact, the repaired fender looks better than the "good" one thanks to a new stone shield made of 0.050" aluminum instead of the thin battered one on the other side. The front suspension was set up to an approximate ride height and after a bit of help from a spare battery and a new set of plugs, the car roared into life. Ahh, I've missed driving this little critter.
Since there is an appointment with C&D coming up, I'm trying to decide how much work I should do to make the car look good. Currently it has a high level of patina - Moab mud in every possible crevice, stone chips on the fenders, missing paint on the nose and front fenders. Little problems like a coolant gauge that jumps around at high RPM and a tach that only works sometimes (I rely on the RevLight when driving anyhow) should probably be rectified. A bit of tidying up is definitely in order - but do I go as far as new paint? I certainly need to fix those louvres in the hood, they're a real problem.
Tonight the new muffler will be welded in. Hopefully it'll be the last time I do this. I'm also going to fit the grille which will make a huge difference to the look of the car. Less than two months until I have to be in Texas, time to get to work!

It's hard to believe this is the same battered fender.
You can see the scuff mark on the side of the car from the cone as well as on the dirty fender. The worst of the damage is hidden behind that stone shield.

Almost.
I got a late start on the Seven last night due to some entertainment with the brand new 2006 MX5 that just arrived at Flyin' Miata.
I can report that a 225/50-16 tire will fit without difficulty. Anyhow, once that was over and the Seven moved in I started cutting up the exhaust. About halfway through I realised that it really wasn't too bright to maroon myself at work if something went wrong but I just kept plugging away. It's the third time I've built the exhaust for this thing, you think I'd be good at it by now. The typical number of little bumbling mistakes and it was ready for paint.
While the paint dried (I couldn't bring myself to watch), I installed the grille. Three well-placed studs on the backside, three slightly oversize holes and wow! It looks so much more finished. Eric is sitting back and saying "I told you so", but it's true. A huge thanks to Chris for donating this to me.
Paint's (almost) dry so I bolted the exhaust on. It looks appropriately sized to the car and will hopefully sound good. I don't know yet because the car decided to simulaneously foul all four plugs and wear out the battery. A jumper box solved the latter but the plug cleaner had vanished into thin air. So had the charger. So the Seven was abandoned in the shop. I'll find out tomorrow if my muffler experimentation is finally complete.

Studs to hold the grille on the nose.
They're not quite as splayed as the wide-angle lens makes them appear.

The grille on the car.
It looks quite different from this morning.

No grille, old exhaust.

12 hours later.
New grille, new exhaust.

March 1, 2006:
Some clean plugs, a full battery and the car fired up immediately.
I've only had the chance to drive the car for a short period but it sounds pretty good. The painful blare at full volume has gone away with the Magnaflow muffler. The car's still loud, but it's good loud and doesn't have any rasp or nasty noises that I've heard so far. Earplugs should not be necessary. We'll see how it behaves as it ages a little.

I couldn't help myself last night.
The garage door was open and beckoning me. Well, I had to see how the new exhaust sounded, didn't I?
And it sounds good. My initial impressions are still true - it's a nice sound right up to redline. It's not a quiet sound but it's acceptable for street use. Quieter than a Harley, that's for sure. When I dropped by to visit some friends who were working on stuffing a twin-turbo rotary into an unsuspecting Miata, they thought a Hayabusa or some other sport bike had pulled up outside. A big part of this was how fast the engine revved when I blipped the throttle as I manouvered around.
Of course, part of the fun of testing at night is the fireballs. On closed throttle deceleration, I'm still running pretty rich. That means that coming into corners the car is blowing flame and making the classic little sports car burbles and pops. Then BLAM! and a fireball. I giggle a lot when this happens.
