At some point when it all comes together I hope you have plans to have someone review and video the results. Thanks for taking us on this journey!

Was not planning to do a review and/or a video. Never have looked for publicity, nor have I ever been trying to compete with any of the vendors around the world that serve the Porsche Community. Perhaps, however, one day, a video could be done, In the interim, however, there are many things, indeed, almost anything and everything, that would seem to be far more important than a video of the work related to my 911R.

Me too. This is the thread I always look first.. and hoping to see updates and pictures of the new parts. The level of engineering and craftsmanship is just so awesome. And taking full advantage of modern technology I suppose.

How is this achieved? Are you able to use a press-brake on titanium?
I'm also curious how you determine the spring rate for the titanium springs.
Also, did you make the lightweight alternator yet? I'm a big fan of your work Sir.

Yes a number of press tools were made in conjunction with the titanium windshield wiper mechanism. As to the lightweight alternator and lightweight starter, both were close to being completed when the virus required closings. Safety for people first!

911R windshield wiper mechanism ordered today. Perhaps it can be translated into carbon fiber and titanium. Also ordered a Numeric Shifter to see if some of it can be done in carbon fiber.

Mr. Linton, obviously you're doing this for the love of the car rather than profit, but I share the same passion with my BMW M3. Would you be able to take on small projects for other makes and models? I'm talking about titanium hood and trunk hinges, and maybe a few brackets. Thanks for any help. And please continue to post pictures, I love the motivation and inspiration.

since this is a lightweight thread, can an engineer comment on this 911 build?

Re the link re holes, it would seem to suggest that the engineers in locations such as Maranello, Munich, Stuttgart, Weissach, Woking, etc. can now be replaced by butchers with drills! Yes, given the virus, budgets are tight but not that tight!! Further, why not go the whole way and use only hand drills!!!

As to hinges, yes, with a good fabricator, they can be made out of titanium. The attached picture was never meant for publication, but it gives some examples. You could also do them out of carbon fiber with bonded aluminum or titanium inserts but, this will require, among other things (costs), mould tools and machining and will be even more expensive.

Well, I was wrong about the new design saving 45 grams per titanium con rod. After a bit more work, the real number is 100 grams per rod, or a total of 600 grams off the crank train.

That is exceptional indeed! Great work, as always.
