Original 917K Factory Blueprint

[tangerine911S]

The following image is available through Pelican and I was wondering if anyone has done anything with the image such as a large poster. I am at Rennselaer and it would be easy and cheap to produce one of these (my roomate is an architect and is very familiar with these type of printers). Some of the lines in the blueprint are missing (just behind the cockpit, tail). Is this they way it came or is it a bad photocopy? Im thinking about filling in those lines before I make a poster. Thoughts?

Heres the link to Pelican:

P.S. You can tell I wrote this before 8am class because I spelled the name of my school wrong (Rensselaer).

I bought a copy of that on blue print type paper at the literature meet in LA last year. It is about 18"x30" and someone must have cleaned up the image quite a bit before printing, because all of the lines are very clear, not broken.

That is the frame from the "new" 917 of Carl Thompson's. The frame had been on display at a company in Europe's office. If I remember correctly they had something to do with the oiling system which is why the tubes in the frame that carried oil are painted red.

Because it is a factory Porsche frame with a real Porsche serial number (917-037) it is being called "the last real 917". (See http://www.pbase.com/917carl) Carl had an incredible pile of original 917 parts from when he worked for Vasek Polak.

Is that frame aluminum?

FWIW, I would be willing to help underwrite the cleaning of and making of a poster of those blueprints.

daepp,

i was just fooling around in photoshop trying to clean it up but apparently i forgot that i suck at photoshop. ill keep playing with it but if you are good at photoshop, give it a go. we have good printing equipment here at RPI so maybe i can get some printed. i am going to find out if it can be printed on blue blueprint paper. that would look sweet.

wavey,

i saw that in a post earlier. there was an article in excellence a few years back where a "new" 917K was built from a chasis (this one?). the guy was collecting 917 parts for years and with the help of others was able to find parts for a complete car. he even found am original wooden shift knob.

I wonder what the 917 chassis weighed?

I am handy with PS but it would be a serious undertaking to fix this to a high quality level. Lots of lines to fill in and digital debris to remove. Hope someone else has the time.

If by chassis, you mean the frame, the aluminum ones originally built for the early long-tail cars weighed 104 pounds. The frames for the short-tail cars were lighter. They even experimented with magnesium tubing. I don't recall what those weighed.

Here's a guess:

Aluminum has an approximate density of 2.70 grams per cc.

104 pounds of aluminum weighs 47,173.6065 grams.

47,173.6065 divided by 2.70 = 17,471.28 cc of aluminum in the frame.

Now, if you assume identical tube sizes, the less-dense magnesium frame would weigh 1.738 grams per cc, which means the frame in magnesium would weigh 30,365.863 grams, or 66.9452685 pounds.

Let's call it 67 pounds, shall we?

Of course this doesn't take account of the additional material required to make the magnesium structure work the same as aluminum, but you get the idea, right?

On the other hand, I bet the car was slower because the driver was afraid of doing his impression of Dresden. . .

I deal with a place that copies blueprints through my job sometimes. If there is some interest, i can look into having some copies made on the same kind of paper, or poster paper for that matter. Here's a pic of two views of the car.

The drivers of the 1971 LeMans winning 917 ( with magnesium frame)....were told it was Magnesium *after* the race !!!!!

I'm in for a poster or repro.

I went and looked up the weight of the first mag frame. Once they sorted out the changes needed to account for the different material, they ended up at 92 pounds.

Paul,

I would possibly be interested in a few copies of the blueprint. I was planning on doing it myself as a little project but am wondering what it would take to make just a few copies (cost?).

[tangerine911S]

After a few days messing around and mindless photoshopping, the print came out well. The work I did may not be obvious at first, but at full size it looks much better. Let me know if you want the full size image as this one is resized with low quality.

Brian,

Thanks for doing all the work on this. What size image is the full size version? Is it good enough for a print, say 16 by 20 , or so?

Thanks,
JR
