Good thing you caught it.

I agree there is nothing like alone time in the shop fixing something that needs repair.
It's like meditation to me.

Re: A great place to get bad news...

I know for the VW axles I get the oem rebuild kits. Are these not available or just not a option?
It is an option -- and I've used it in the past. But as I get older, and the cost of the kits (for Porsche -- so there's a premium) goes up, the new axles come to seem prudent. We'll see. I always hold on to the old ones, although today I trashed about six axles going back to build dates of 1998. I'll rebuild these if I have time and can thoroughly inspect the balls and the cage for wear.

a tow truck is always better than having several tow trucks to pick up the pieces, am I right?

Glad you caught it in time. What resolution do those cameras shoot in and do they handle shock decently? Might be an inexpensive solution to a gopro until I can afford one.
The cameras shoot true 720p. The nice thing about a GoPro (or others of that ilk) is a screen where you can see what you're shooting and also review what you've shot. These are blind until you move the chip to your computer. And I don't know if the image quality is as good as the GoPros. But for what I do, they're great.

One of those special moments in shop life. If only those could be captured in a bottle and used again.

I can identify with the windshield deal - busted the windshield on the Falcon during shop construction.
A garage/shop is the place where we see the highest highs of our 'car guy' lives and also the lowest lows. :beer:

(Unless love/career/kids or any of that outranks the relationship between a man and his car. I'm not prepared to pronounce any kind of final judgement on that.)

EXCELLENT! What we have here is a pre event tech inspection. The kind all should go through prior to taking one's car onto the track. Been doing it for 25+ years now and have replaced many "questionable" components that "maybe could have lasted but were replaced anyway".

Job well done!
Thanks. I always do a basic nut-and-bolt check. The lift makes that a lot easier. I keep a checklist on the computer so that the 100th track day has the same thoroughness as the 10th. (For the record, I'm well past the 100th.)

How much work was it to move your engine?
Well, the guy who built my car did it -- so for me it was easy. But the **** rod had to be shortened. The mounting points for the transaxle and engine had to be moved. There were a couple of other fine adjustments with the clutch and throttle, if I remember right. The base for the torsion bars had to be cut out, as well -- which meant other reinforcements to the chassis. But I was also going from torsion bars to coil springs, so that was an opportunity to shed some weight.

That's great but didn't you get some seat time in something exotic when the last one let go at the track? I guess you can't count on that happening every time.
You have a good memory -- of something I'll never forget. Yes, that day I got to do the remainder of my laps in this seat:

Driving a friend's car. Bucket list item checked. :thumbup:

Glad you found the issues before they grew. Tech inspection before racing is wise.

Is there a link to the cameras or am I going blind?

It would also be interesting to see video quality from the new cameras if you don't mind sharing.
By the time I post them, they've been processed down (basically copied and recopied), partly because I'm lazy and partly because I use the free editing software that came with my computer.
But here's a pair of clips that show them being used. One is mostly the forward/in-car cameras, combined:

<iframe width="853" height="480" src="http://www.youtube.com/embed/lYiko8lJnhs?list=UUaV32MkrMyaz9Kq2IXnD2FQ&hl=en_US" frameborder="0" allowfullscreen></iframe>

One includes the rear-view:

(But again, these don't show you the quality of the raw footage.)

I got the wide-angle ones from this ebay seller

Bad news - but admit it. You loved the fact that you knew what to look for, found it, and fixed it on your own. That is why hard corps Garage Journal guys (and gals) have garages. "Smudge of grease"? On Jack Olsen's Porsche undercarriage? If your garage is any indication then I can understand why your alarm went off.
Well, I looked for it because two years ago it ended my day at the track -- so it's one of those things I look for, now. But I'm going to disagree with you about the clean undercarriage. It's pretty dirty around the transaxle, especially. It's magnesium, which is soft -- and it's 35 years old -- so it's soft and a little leaky. Plus, there's all the grease from the CV failure from two years ago. That stuff is just about impossible to clean up.

Here's a clip where you can see the clean underbody cover, and also get a glimpse of the dirty transaxle:

<iframe width="853" height="480" src="http://www.youtube.com/embed/XS2HV2kNVHo?rel=0" frameborder="0" allowfullscreen></iframe>

But yes, I'm probably a little proud of myself for catching it. :)

These cameras are readily available on ebay, I know a lot of guys who use them for track cams, especially mounted to the front splitter or other outside location - and especially since the investment is so low if you lose one.

But how do you start them all when mounted all over the car?
I sync them on the computer, so they don't need to be started at exactly the same time. And the new software for them allows you to set them to start recording as soon as you turn them on -- which is a lot simpler than how they used to be.

Good thing you caught it.

I agree there is nothing like alone time in the shop fixing something that needs repair. It's like meditation to me.
I agree. I like my day job just fine. But there's no substitute for having the time and the ability to repair your own car -- especially one you trust at very high speeds.

Re: A great place to get bad news...

How do you log the speed/tach data and embed that in the video?

Isn't that cool? It's a piece of software that works with the data logger's data file. You have to find one sync point, but then it takes care of the rest -- and it's got a bunch of different 'dashboards' you can choose from. The only problem from my point of view is that it's a PC-only program. So I have to burn that onto the video before I bring it over to my Mac laptop for the rest of the editing. I lose a generation's worth of image quality, but it's nice to be able to see the actual speed I'm going on parts of the track where I'd be crazy to look down at the speedo.

Just watched those clips you posted. Gah! Oil on the track!

As a rider, I think I just swallowed my tongue.
Yeah. It's one of those 'lighting-strike' things that you have no control over and could possibly kill you. But as long as you're still alive, you'll assume the worst consequence would be a spin.

Heck yeah it's cool! (lap time / position as well). Can you name any specifics (regarding the logger and the software) of what you're using?

Re: A great place to get bad news...

Good find Jack!

You may want to check out The Driveshaft Shop for future replacement axles.. The axles and CVs for my GT40 are actually high misalignment Porsche 930 units.. There are a lot of guys that run 600+ HP through these...

Ummm, time-warp going on with the "Open Track Racing, November 14, 2012"? :lol:

http://www.youtube.com/watch?feature=player_embedded&v=XS2HV2kNVHo

:D

Or is that just a lead-in edit for a work-in-progress with pre-race footage put in now and actual race footage to come later?
Yeah, it's an unused 'header' piece. But it shows the underside of the car.

Good find Jack!

Thanks. I sent them an email. It would be nice to find out if someone has combined the 930 joints with a Carrera axle.

I can understand that. It's not very pretty to look at, but it's still my favorite track.

Now that you have posted a video at 2X speed, I want a car with a 14,000 RPM motor.
It's kind of like a racing kart, isn't it? Hard to believe that's the equivalent of a 260-mph corner. :lol:

So...

The axles arrived at 1:15 today.

fedexbox.jpg


Both assemblies went in pretty quickly, since I'd been able to loosen everything up the day before. Here's my 'poor man's torque wrench. My body weight 26-1/2" out from center produces 340 foot pounds of torque.

storquewrench.jpg


Everything was wrapped up and ready to drive in 38 minutes.

readytoride.jpg


Driven around the block, 12 bolts re-torqued -- and my tools put away. Lunch hour was over -- and I still had time to eat some lunch.

Re: A great place to get bad news...

Good catch, before everything I take the 968 race car out I do a nut and bolt check, for awhile I kept having the CV joint bolts wanting to back out. Which torque wrench do you have, I changed my rear bearings last year and while I could take everything apart and replace the bearings I had to take it to a friends shop to torque them.

Re: A great place to get bad news...

That's just it. I don't have a torque wrench that can measure 340 foot pounds. So I simply use the fact that 1 lb suspended 1 foot from the fastener equals 1 foot pound. If I weighed 340 pounds, I could rest my weight 12" from the center of the wheel and produce the right torque. I don't weigh that much, though, so I have to move out on the cheater bar a little more than 2 feet. The wrench itself is just a 3/4" drive ratchet and a 32mm socket.

Well, yeah, 2 cycle karts do 14 K and better. 2 motors max for class racing. But since your 2X video shows 6 cyls at 14K RPM 4-stroke style, all I'd need is 3 100cc motors to duplicate the sound.

However, to duplicate the power, I'd need a lot more volume. The there's power to weight ratio thing. A kart is 200 lbs with a lot of gear attached,

The red is gloss; the green is semi-gloss. Plus, I can't get the Regal Red locally in cans (I finally got some online, but it's more expensive that way). So it made sense to get spray cans of the gloss stuff. If I could get the green in cans, I would probably use it on some things. But it's latex and it's also a discontinued color. And semi-gloss is a lot more forgiving than a full gloss.
I'm torn between rolling semi-gloss on my Vidmars and Lyons vs spraying gloss from a spray gun. I just wanted to know why you didn't roll your red using semi-gloss latex. I'm sure Lowes/HD can mix you up a Regal Red can of latex.

Thanks again for an inspiring garage. Your garage is making me want to clean up mine.

If I'd had access to a semi-gloss that I could have rolled on, I might have done it. But I'm mostly motivated by convenience and laziness. The local hardware store had spray cans of the Regal Red, so that's what I went with.

Then again, when I painted the lift I got an acrylic latex mixed, since I didn't want to have to do two coats (the Weatherbeater paint most of my garage is painted with is a lousy paint that requires multiple coats). If you're going to be painting over exposed metal at all, then you might want to think about something that will be more rust-resistant than household latex.

It generates chips that are similar to sawdust. Easy to clean up. And unlike an abrasive disk, no smoke/dust to choke on.

I've used a 7-1/4" circular saw for this kind of cutting for years, and I wasn't looking for something to replace that. A Skill 77 and a Freud blade will go through inch-thick steel. But out of the shop, this might be a useful alternative for when a light-weight saw or not having to run a power cord is important. The thing that prompted me to do it was a pergola I'm planning to build, which might need cuts made up high if I don't get all of my measurements right on the first try.

Damn, another thing I need for my place. Thanks for sharing this, so I can get rid of my old hacksaw.

Cheers :beer:

Re: A great place to get bad news...

I think I'll shoot this over to Drew Salter and http://instant-G.com Steve Timmins and the rest of the loop.

Meanwhile at Daytona Speedway at this weekend's Historic Sportscar Racing, this poor guy pulls off the track with blue smoke. I said to my friend, "watch this...that guy will open it up and discharge a whole bottle of dry chem in the engine compartment then the interior even if the driver says not to.

Sure enough, the overweight first responder grabs the dry chem first thing. Fortunately the smoke stopped before the hoses started spraying. There were 2 rollback wreckers, an ambulance, 2 firetrucks and a white pickup with more trucks rolling when the full course caution came out.

Willow Run...is that the place out in the White Mountains of AZ ?

About a buck fifty, but the work boots nudge that number up a little.

I bet you would love to race your Porsche on that track:

Definitely on the bucket list. But a scary track to learn -- and because it's public, you never know what's going to run into you.

had to re read the post after that :lol_hitti:lol_hitti

Whoops. And the software for the forum let it through. :dunno:

Well, as of today, the old car is cleaned up, winged up, and ready to go. The weatherman says it'll be 71° out there tomorrow and there's only a 1% chance of rain. :)

It was a great day. No issues with the axles, and I ran some very quick laps.

My only setback was losing a (second) set of uprights for my home-made wing. I keep trying to save half a pound or so by making them lighter. I'm going to have to give up on that, I think.

Here's a picture of the wing (with an exaggerating wide-angle lens).

readytogoo.jpg


And as it happens, my rear-facing camera was showing the wing's shadow at the moment they gave out. You can see the shadow of them collapsing just as I am straightening the car out after a fast right-hand sweeper. I felt it when it happened, but fortunately it didn't upset the car at all. I drove one more lap, brought the car in, and then ran the rest of the day without the aero stuff bolted on.

Wing Upright Failure Video

More video and pictures will follow -- but I wanted to upload this one first.

Jack, I had a wing fail on the F4 (HOTFR8) every one said to me it is just for looks and laughed at the wing but I know it is great and works even when towing something. When I built the F4 every thing had to be strong. The failure was due to down force on the bolts only and not on the bracket. The wing surprisingly does work even on the back of the truck obviously or the bolts would not have broken. The motto during the build was to over kill every thing that could break but we never expected bolts to fail. Replaced with hi tensile and fixed.

Will be waiting to see more and how you update the mounts, brackets etc.

Corner workers,pit workers and course marshals are trained to take a fire extinguisher when responding to a disabled car. So if the blue smoke turns to black from a fire they don't have to run back to get it costing valuable time. Also the corner workers have an elaborate sign language to communicate with each other since most time radio's or yelling get's drowned out by noise. Yes sometimes you get someone who get's over excited but remember there volunteers taking time out of there lives and there own money to be there. As a former course marshal in Central Division of SCCA I encourage you to come out a weekend and work a corner or be a course marshal or pit worker and see thing's from the other side of the fence :thumbup:

if you made your diagonal brace into an X brace i bet it would have saved the uprights in this case. as always nice car and space.

On the wing stands, I would guess that the downforce reached a point where a little bit of side force caused a column buckling type failure. If there had not been the turn, it might have supported the load. A little bit "thicker" supports might help more than cutting less material out--adding some cylindrical section might improve things (teardrop section tubing?). This might be harder to fab, so maybe just reinforcing the front of the support would help. The aerodynamic force should act at the 1/4 chord point (25% back from the leading edge), so the front of the support is carrying all the load. If you doubled or tripled the thickness of the forward leg, that might fix the problem. It probably would not be necessary to add the stiffeners all the way to the bottom if that would interfer with mounting, but as far down as possible/convenient would be helpful.

Hope that helps you out.

Glad to see/hear it didn't upset the car. I think I see one diagonal brace (a rod?) to provide lateral support. Something does look a bit out of proportion to me though. Height of brace vs. width and amount of bracing. I sent you a private message, let me know if I can help with the design.
