Cut out the panel behind the headrests, completing the upper engine compartment, though some panels don’t have fastener holes yet. These panels, unlike on Kimini, are being made removable. As noted elsewhere, Kimini unfortunately became something of a Rubik’s cube it was built from the center out, making it all but impossible to access certain areas once they were buttoned up. Lesson learned, all the panels around Midlana’s engine compartment are being made removable increase accessibility.

Based on Kimini’s diaries, it was 3.5 years from the start of construction to first drive, then it took years more of fussing with the composite shell and doors. Midlana’s construction just passed the two-year mark so it’s going pretty well. The rough goal is to drive the car down the street and back in February, which gives time to make the front caliper brackets, plumb the front brakes, and whatever else needs to be done – things like, oh, a temporary floor! While the real floor panel is cut and drilled, the car sits so low that there’s a risk of removing Clecos over a speed bump, or perhaps worse, bending them over so they can’t be removed. The “drive down the street and back” means just that, no smoky burnout, no drifting around turns, and no multiple laps – simply a mental milepost that it can move on its own, and no doubt a reminder of the thousand loose ends.

Happy New Year everyone!

Received a well-intended e-mail licking from a good buddy who saw my proposed lime-green/gray color scheme – and hated it. Proving that I’m somewhat insecure and not impervious to negative input, other color schemes are being considered. One much more sedate and understated combo is substituting navy gray for the green. Yet another is flat black for the paneling and light gray for the chassis and suspension, though it’s becoming less and less “original”, what with the so-called rat rod look becoming so prevalent (how much do I care?) I’m a bit hesitant to go to a three-color combination though Kimini pulled it off: red suspension, gray chassis, black interior panels, and a silver shell. We’ll see – colors are subject to change at any moment…

On-call through Sunday morning, so progress will range from none to decent.

The engine cover mounts are done, short of sizing the Dzus fasteners. Aerodynamic lift might be (I really don’t know) substantial since the engine cover is so large, so fasteners are on 12″-centers around the edge plus one near the center. Don’t want the thin material to bow upward due to low pressure, or start flapping about. There’s the small chance of getting rear-ended and having the forward edge of the engine cover try to enter the passenger compartment. It shouldn’t be an issue due to the seat-backs and main roll hoop diagonal, but some people may use low-back seats and no diagonal (really bad ideas for a number of reasons), so I don’t want to set a bad example.

I was asked why I don’t buy brackets instead of making them; some places make all sorts of brackets so surely I could find ones that would work as-is. Hah, I’d love to but there’s no way they’ll be correct. Every bracket, no matter how well-chosen, would have to be reworked, so I don’t believe there’s enough time-savings to warrant buying them. Also, due to build variations, even brackets which should be mirror-images of each other are slightly different due to build variances, so I  don’t see that they would work out, but I could be wrong.

Not sure how much will be accomplished tomorrow, as I’ve been informed I will be going “shopping.”

Things are moving along, albeit slowly. The coolant overflow tank and engine catch-can mounts are done. The coolant overflow tank isn’t an option because without one the cooling system will slowly pump itself down each time the cooling system comes up to temperature. The other tank, the catch-can, collects and separates  air-oil blowby from the engine block and head. In an OEM car it’s recycled back into the intake to be burned, but since the engine’s turbocharged (and no emissions issues are at stake) it’s not a good thing performance-wise to recycle it. Some people just run a hose from the engine down to the ground and as much as I’m all for simple, light, and cheap, the thought of having a hose spewing smoke from under the car doesn’t paint a pretty picture.

This is the stage of the project that can become a big mental drag due to so many loose ends (it was the same with Kimini, too.) Coming into the garage, there are no longer any  clear-cut sub-projects to work on; virtually every part of the car is unfinished to some degree so there’s no rewarding sense of progress happening after a day’s work. Brackets are a big culprit to this malaise; they take a disproportionate amount of time to make, and yet every one of them is needed, but offer up little in terms of payoff (they’re just silly brackets!) Then there’s the danger of second-guessing what’s already been accomplished.

Every time I look at the screen at the rear of the engine cover, there’s a very strong desire to cut it out and do it over again with a denser mesh. Anyway… next are the brackets for the Dzus mounts on the engine cover.

Worked on two small light projects: the high-mounted rear brake light and the rear view mirror. The reasoning goes that since everything has to be done before it comes apart for paint it doesn’t matter the order in which things are finished. Both got done though the jury’s out on the brake light, being offset below the main roll hoop to leave room for the wires to exit the unit. It’ll be left a few weeks then it’ll be looked at again and maybe cut off and raised to be in-line with the hoop.

On the other hand, the rear view mirror worked out well because the windscreen top is lower than the main roll hoop, so it’s got a good field-of-view. It’s also nearly invisible from the front yet doesn’t block any forward visibility. I had one of these Wink multi-pane mirrors before and really like it, though it remains to be seen how the flip-down sun visors will integrate with it.

It must be a sign of being married a long time: sitting at the computer writing, when over the sound of iTunes I gradually become aware that my wife is talking to me. I didn’t ask how long the conversation had been going on…

Anyhow, after picking up her at the airport late Friday night, shopping yesterday, and being on-call the last three days, the book was worked on instead of being out in the garage. While the majority of the book is done and the framework is in-place, there’s still many missing sections. Also, it’s rather vexing to look at literally any of the 340-something pages and see things that need changing. Even though it’s moving forward, it doesn’t give a big sense of progress.

9 Dec 2010

The passenger-side body panel is done, trimmed and drilled. The remaining engine compartment panel which is behind the head-rests, has been mocked up in cardboard. However, I’m on-call tomorrow and the weekend so further progress is uncertain. Looking forward, front brake caliper mounts will be made up early next month in preparation of at least driving down the street and back. As it is, the new rear brake pads and new rear rotors do NOT work well at all, barely keeping the car from rolling down the trailer ramps, so they’re being considered useless until they’re bed-in.

8 Dec 2010

Finished the engine compartment screen vent. It came out okay, though aestetically it might look better with a higher wire count, but as was said, the fewer the wires the lower the resistance to airflow. I was reminded that another way of attaching screen to a frame is via TIG brazing, something I’ve never tried and don’t have the rod for, but it’s filed away for next time. Still waiting on the second two LED taillights… On other fronts, the right-hand side body panel will be completed tomorrow morning, then there’s cleaning up the house and babysitting the refrigerator repair guy… we’ll see how that goes.

7 Dec 2010

Cut out the right-side chassis panel; note the corrosion, caused by it raining on the way home after picking up the material and not drying off the sheets. The consequences of letting two sheets sit with water between them wasn’t fully understood, but it is now! In this case it’s not a problem since the panels will be painted, but had the car been set to use polished panels it would have been. Speaking of polished panels, I’ve yet to ever buy a sheet of new aluminum that wasn’t scratched and/or dented – maybe I’m buying from the wrong place.

Anyhow, right after the panel was cut out, the screen arrived for the engine compartment. For a change of pace, the rest of the day was spent welding 0.047″ diameter wire to the frame – and it’s still not done. It’s pretty safe to say this isn’t something that can be done with a MIG welder! It could have been riveted in, but because Kimini’s front grill (fabricated the same way) came out so strong that it seemed worth the effort. It remains to be seen if this screen density is too thin, because the material is a bit too flexible. Doing it again, 0.063″ diameter wire probably should have been used, but once in the frame it may be just fine. That’ll be clear tomorrow after it’s fully welded. The reason thinner wire – and lower wire count – was used was to minimize air-flow restriction. Same goes for the inlet screen on the sides of the engine compartment, and the radiator inlet screen. That one however, uses a higher count screen to cut down on the size of pebbles that can make it through.

In other news, I’ve had a few people say I better go with colored taillights, but as was mentioned, it’s hard to see what’s wrong with it when new cars on the road have the same arrangement. I was sitting behind a Toyota Prius today and sure enough, it has completely clear taillights so I’m not too worried.

6 Dec 2010

After a lot of mocking up and double-checking the left-side side panel was cut. This was something of a big deal, both psychologically and financially. Psychologically because putting big parts on the car does wonders for a sense of progress. Financially because it’s a 8-ft long piece that was expensive to have cut (my truck is too small to easily get a 4′ x 8′ sheet home.) Anyway, all is well, and it seemed a good time to take another family picture with the incredibly handsome builder. The car is once again sitting on her own wheels and the nose has be lowered to near ride-height, it gives a better sense of its size.

The last picture shows the relationship of the nose and front tires. When it first became clear that the front tires are at the same height as the nose, and will be even taller once the front fenders are in-place – cool.

The dash cover may be redone. The first one’s okay but a little rough and perhaps best left as a learning experience. I also want to try a slightly different way of fabricating it in order to make it a lot simpler. If the redo isn’t any better, no problem, the original will do – we’ll see.
