build diary

November 29, 2004:
Well, some of the wiper bits I wanted arrived today.
They're from a Series III Land Rover, but it appears that the outer diameter of the wheelbox is greater. This means I can't use the nice Midget angled bits that I have. No worries, there are a set of MGB wheelboxes on the way which should complete the set. Weird parts from everywhere.

No new progress on the tach front, but I have been looking at the oil pan. I think I'll cut 1" off the bottom and possibly add an Accusump to the system. It's not going to be an easy job as the pan is cast aluminum (time for some good cleaning!) and there's no simple cut to be made. Still, it'll give me some needed ground clearance. Luckily there are extra pans around the Flyin' Miata shop so I can do this without having to take the car off the road. Well, if it stops snowing anyhow.

Random wiper parts!
These are from a Land Rover. Hmm, the diameter of the threaded section is smaller than my Midget parts. Good thing I have some of those arriving soon.

The oil pan surgery.
Cut along the pink line...

December 2, 2004:
A cold snap has meant that snow is staying on the roads, thus the Seven is staying in a cold garage.
Strange, last winter I was willing to work there in cold, cold temperatures but I'm less motivated right now. This doesn't mean I'm sitting still. A number of projects are in the planning (ie, thinking) stages. I'm waiting for the last wiper parts to appear. I'm thinking about how I'd like the tach to work and reading specifications on an enormous number of LEDs as I want them matched and visible in the day, harder than it sounds. I've made arrangements for a spare 1.6 oil pan to be hot-tanked so it'll be easier to weld the cast aluminum although a member of the GRM message board mentioned that some other cars use a steel pan that will fit. Hmm. The head will also be coming off the engine before too long for a valve job - despite a basically new engine, it seems to suck back some oil at idle and high-vacuum operation. Turns out the head didn't get new seals and guides when it was apart for the porting. I might also get a set of high-rpm valves and titanium retainers installed. Why? Because I can! I'm also thinking the upcoming FM supercharger prototype for the 1.6 cars should be tested on the Seven. Just to make the car a little more interesting.

December 6, 2004:
A friend needed some tires, so I donated the set that was on my spare wheels.
This means I have four bare wheels just waiting for me to do something interesting. Trouble? Oh, of course! They're standard 1990 Miata wheels with the pesudo-Panasport look and light weight, perfect for the car. Being a child of the 80's, I want to paint them black with a polished lip. I've always liked this look and I think it will suit the car well. Ideally I'd match the paint on the front fenders but I don't know if I'll be willing to spring for more BMW paint. This thread on Miataforum has some good directions as well as photos of some nicely finished wheels. A bit of playing around with Photoshop has shown that this should look good. As usual, I am open to suggestions via email or the guestbook. These will end up as my normal street wheels with Azenis tires. I'll also have to do some repair on the wheels as the previous owner sometimes parked by feel.

On other fronts, the oil pan is being cleaned right now and I'm trying to decide on the valve springs. It's a reasonable price for me, I just have to suck it up and do it. I also received my remaining wiper parts and they'll do the job perfectly. It'll take some nerve to cut into that scuttle for the wipers but it really does need to be done eventually. I am also contemplating some changes to the suspension setup based on what I'm seeing in photos, most noteably increased ride height.

Black wheels with a polished lip? I like it.
Here is the original with "stock" wheels.

Not all the photoshop experiments worked out.
It's dramatic, but I think I like the polish better.

December 8, 2004:
Yes, I should be working on something useful like the wipers or the tach.
But instead, I'm all excited about the wheels. They'll be black with polished lips when I'm done. First I have to strip off the existing paint and clean them up. Easy enough if I can leave work long enough to pick up some paint stripper. I figure I'll probably try polishing the lips by hand. Should be slow and messy. Once the wheels are done I can put on a set of good tires and stop using cast-offs and borrowed bits.

In terms of real work, I hope to put the wipers on this weekend. I'll make it easy to remove the motor because it's a heavy beast, but the rest will probably stay in place. I also need to get those LEDs...

For light entertainment, try reading the warnings on the back of a can of aircraft paint stripper sometime.
Yikes. I put on my brave pants (and solvent-proof gloves) and decided to go ahead anyhow. The first indications were promising with lots of bubbling paint that easily scrubbed off. But if you look carefully at a Miata wheel, you'll see that the rim and a face on the spokes is machined while the rest has a sand texture. The paint/powdercoat/whatever on the wheel is very well adhered to this textured surface. Four rounds with the stripper and I still couldn't get it clean. It may be time for some sort of media blasting. At least I did manage to remove a fairly copious amount of paint. Ever wonder why you never see a Miata with peeling paint on the wheels? It's obvious to me now!

The wheels with tires removed.
They're dirty with a few scuffs but I think they'll look great when I'm done.
entry 714
The first step in stripping the wheels - aircraft paint stripper.
entry 715
Looks promising, the factory paint is bubbling up nicely.
entry 716
After several rounds with stripper, this is the result.
The polished rim is mostly clean as are the polished edges of the spokes - but the textured part of the wheel is not giving up.
entry 717
My new oil pan is back from being hot-tanked.
At least something is cleaning up!

December 11, 2004:
Finally, a decent photo of the car with the windshield.
I'm still considering building another that's a bit lower.
entry 719
Every time I clean the car, it rains.
The last cleaning - the best so far - caused record snowfall. So it's going to stay dirty for a while so I can use it.

Better stripper.
I've been told via email and the guestbook that my paint stripper was not manly enough. The key is to use the semi-gelled type that paints on. The paint shop that recommended the spray-on stuff was wrong! Once again, after finding the pros didn't quite have what I needed I headed for Lowes. A bottle of Jasco stripper cost less than a single spray can and it definitely did the job. Combined with a solvent-proof brush from Walmart, a Scotch Brite pad and a not-solvent-proof scraper I was able to make a huge difference to the wheels. Tomorrow I'll see how they paint. Thanks to Richard and Jonathan for the tips.

I was busy over the weekend driving. I brought a video camera along and I've put some pretty fun videos together. Nothing fancy (yet), just some back road driving. This will give you a hint of the sort of roads that we have right on the edge of town. They sure look fast in the little versions, holy cow. Want to see them?

Not the biggest installation, but a Voodoo brake handle has replaced the plastic one.
Hey, it matches the car. My titanium shift knob also made it onto the car. Why? Because I like it.
entry 722
A future installation - this net from BMW.
It'll go on the passenger's side of the transmission tunnel to corral loose papers and sunglasses.
entry 723
The gelled stripper did the job.
A couple of drops of water mar the finish here, but you can see the difference from the earlier stuff. That's a clean wheel!
entry 724
More videos!
These are some fun ones to watch. Watch the videos here.
