I fixed the clutch problem last night so that I could drive the Seven to work.
A Time-Sert thread insert and problem solved! I still need to put a limiter on the pedal. The windshield will go on the car this weekend as we're having a bit of a boy's night out tonight, playing Gran Turismo on a giant TV with my homemade "driving pod". Hey, we're all kids at heart.

I spent the day working on installing the new lift at Flyin' Miata and building the windscreen for the Seven.
Jonathan Adams and I have been chatting about how to attach the windscreen to the car and I am shamelessly using his suggestions instead of the setup I had originally suggested. I'm having a bit of trouble getting everything built to the quality that I want so it's taking a long time. I might start a couple of sections over. But it's raining outside so it's not like I can drive the car...

The windshield will be held to the side braces by this steel insert inside the channel.
entry 685
The first part of a side brace is ready.
I'm not sure if I'll expand this to use four screws instead of three.
entry 686
This is how I'll fasten the two sections of the windshield frame together.
The rivet heat will be hidden behind the bracket when it's installed. The "book" method wouldn't have worked on my 1/16" channel. Ignore the poor fit of my test item, please!

Well, the windshield frame is finished and the side braces are ready to go.
I started over with my setup for fastening the side braces to the frame because I just couldn't get the finish I wanted. A note - countersunk fasteners are not very tolerant of any sort of mistake! Your eye can easily pick out an off-center fastener. Some careful cutting and measuring has given me an acceptable fit now. The side braces are done and look good. They took a little bit of tweaking in terms of angles to allow them to sit flat on the sides of the car but it did go fairly quickly. I started to install the glass - and hit a problem. The glass must be very slightly larger than the plywood. Enough that my tight tolerances were too tight but not enough to notice when you lay the glass on the wood! Once the inner tube was added, it was obvious that there was no way to install the frame around it. So I have two options - make the glass slightly smaller or make the frame bigger. I'll ask the glass shop tomorrow if it's possible to grind this down, and how. I'm happy with how everything else turned out but I had really hoped to drive the car today with the new windshield. Oh well...

Test fitting the completed frame.
Bill's suggestion? "Bigger holes in the wood so you can see where you're going."

To install the windshield into the frame, I think I'll use inner tube.
It's easy to remove and gives a good fit. Two 26" tubes are needed for the whole windshield.

The windshield is done!
I'm a little too excited about this, methinks, but for some reason it feels like the car is done. It's not - it needs wipers to be legal - but I can drive without goggles and the car looks better balanced. I'm still not sure if the glass should be 1" shorter but it works.
It turned out that the easiest way to get the glass to fit was to cut a new piece. It cost about the same as making a new frame and was much faster. Once again The Glass Brokerage in Grand Junction came through, working hard to make the perfect piece of glass and turning it around the same day. All for $30. Have I mentioned how much I like doing business with them? I'll be bringing the car by to show it off today because they're curious about what they've been working on.
With the new piece of glass, it was a matter of minutes to fit it inside the frame. The fitment is perfect with nice tight joints. Whew! I had been worried about that. I used a razor blade to cut away the extra inner tube, bolted up the side brackets and drilled a few holes in the scuttle. Voila, a windshield and a car that looks better! Funny, I'd never thought it needed the glass before but it's well balanced visually.
Driving the car with the glass in place is really nice. I have lots of visibility without the top cutting off any of my vision and I can comfortably drive without glasses. There's still turbulence - of course - but it's manageable. I had a great drive in to work today in crisp conditions and a big stupid grin on my face.

The new windshield glass is installed in the frame.
Now I have to trim the leftover inner tube.
entry 694
To protect the paint on the scuttle, some leftover inner tube was glued to the inside of the side brackets.

A detail of the windshield installed.
Some of the contouring of the side brackets can be seen here. The countersunk bolts make for a clean installation.
entry 696
A side view of the brackets.
I'm very happy with the symmetry here.
entry 697
The car looks better with the windshield - that was a bit of a suprise.

Not exciting, but required.

Much excitement!
The December 2004 issue of Grassroots Motorsports magazine is here. There's a two page article on my build in it to accompany the latest update on their own car. Everyone, run out and buy a copy then email GRM to tell them how much you like it! I am honored. I've compared notes with the GRM crew on a couple of things and persistent readers know that their frame was built at the same time as mine. There's not much new information in the article but it still feels good to have it in print. As if I didn't have a big enough grin on my face from the drive to work already...

I'm excited about this one.

For those who want to skip to the end of a build, Grassroots is selling their "2 day" car.
Contact the good folks there for more information. As for myself, I'm gathering parts to build the wipers. All I need now is the cable to drive them and that's pretty easy to hunt down. I'm also considering building another windshield that's a bit lower but that's not too high on the priority list. Instead, I'll finish the wipers once all the parts have arrived and then move on to a couple of other things I wanted to try - an LED strip tachometer and an investigation into the effects of bump steer come to mind.
