Hi all, Just to clarify my position with respect to the rebadged Nitron shox (now GTS). To anyone who wishes to place a £20 deposit with me now, and anyone...
... Tom, when you get around to getting your hands dirty try WD-40. I recently found it works great for getting semi-cured poly resin off your hands. And...
I can't see that it does anything, except empty your wallet. At best, it may act as a lock (similar to welding the diff); at worst, it will disintegrate and...
I am kinda with Peter here. And the thing is $300 for two little bits of metal and some springs. $300 is well on the way to the price of a true LSD. Even...
... and I want your opinion on it's validity. ... Kind of looks like a Powertrax Lockright or Detroit EZ-Locker except for the funky shape and helical shapes...
With the discussion of tube frame vs. ladder frame vs. monocoque a while back, I was thinking about what would be a way to increase the stiffness of the basic...
I think what you are describing is very similar to stressed skin construction? Similar to airplanes? To make another suggestion regarding this thread. What if...
Here's an example (in aluminum) of what you propose. http://www.geocities.com/MotorCity/7630/index.html You can eliminate the diagonal reinforcements only if...
Hello to all of you, Just adding sheet metal to the basic Locost chassis will mainly add weight and some extra stiffness. The frame already is rather sound....
Lotus Elans have a backbone of folded sheet. Really a long rectangular box open at each end, and from each end the suspension supports spread out. Very...
Hi Guys In the book, Race Car Chassis (Forbes Aird), there is a picture of exactly what you are describing. It is on a car build for the Shell Fuelathon...
Hi Dan, In AUS that is how we take a "book chassis" which will give about 1500 Nm/deg to high 3,000's. Weld in panels in the tunnel, footwell fronts, and...
This is a slide show of a bike engined D Sports racer. Lots of interesting details detailed in their build. http://homepage.mac.com/stohr/PhotoAlbum1.html...
Can anyone recommend some good books on the Lotus 7? I'm looking for anything that might discuss the technical changes made to the 7 over its life time. Stuff...
A while back there was discussion on torsion bar (TB) front suspension and someone had a formula for working out the spring rate depending on TB diameter. I...
The formula for calculating spring rate is: k=d^4G where k=spring rate, d=diameter, G=modulus of elasticity (constant for steel) so ignoring the constant: %...
... Beatle, This is something I've raised on this group a few times as I actively considered using torsion springing on the front of my mid-engine design ...
Has anyone taken the time to analyze the roll centers that result from the book chassis? Just from off-the-cuff looking at them they strike me as being a ...
I just think this needs saying from time to time: The very liberal law that sllows anyone to build almost anything and call it an Experimental Airplane in the...
Is a high roll centre a bad thing given that the cars COG will pivot about the roll centre. My understanding was that car designers initially designed low roll...
Unfortunately there is no definative Seven book. Ortenburgers book is very good for Lotus and early Caterham Sevens. Another good book is Tony Weales' ...
Thanks heaps Dominic, and especially so for clarifying the D*D*D*D part !! As you suggest I may be OK to use the thinnest available standard TB (19mm) for the...
This is for Tom Hale (or anyone else close to Seattle who'd doing vacuum bag frp layups) I was in the Boeing Surplus store yesterday. They've got a big roll of...
You guys on the northwest coast are so lucky to have Boeing surplus up there. I'm an A&P on the east coast and I keep hearing all these stories of great,...
