It really boils down to a matter of what it will cost. If outright performance is your goal then magnesium is the way to go. As a guide, a typical 17 x 11 magnesium wheel for a V8 Supercar weighs around 9.0 kg whereas the same size wheel made from aluminium would weigh around 13.5 kg...

How about some real life circular planetary gears that actually do something? 14 cyl Bristol Hercules sleeve valve radial aircraft engine...

More info on the old RF wind up - I called the RF administrators today as I had not received any communication from them since (once again) sending in my Proof of Debt claim last March. I just wanted to make sure I was still on the list and hadn't slipped through the cracks! I was told...

A JOKE TO OFFEND EVERY GENDER AND NATIONALITY On a group of beautiful deserted islands in the middle of nowhere, the following people are suddenly stranded by, as you might expect, a shipwreck: 2 Italian men and 1 Italian woman 2 French men and 1 French woman 2 German men and 1...

Hi Dave, Yes I did find a pic of them on a motorcycle but is not shot from a very good angle. I guess that with them fitted to a motorcycle at least you have a fair chance of keeping both sides of the wheel clean!!!

They are called Radurra wheels - Radurra is Italian for Clear The creator and patent holder of “the clear wheel” Doug McGoon and Forgiato have combined to turn this idea into a real drivable wheel. In 2006 we proudly produced and introduced “The Clear Wheel” called Radurra for cars and...

Hi Guys, Does anyone have access to any engineering drawings showing the manufacturing dimensions and tolerances for Rudge-Whitworth, spline drive, wire spoked wheel hubs? This type of splined hub was used by Borrani for their wire spoked wheels on the Mk1 and Mk 111 GT40s as well as by...

Hi Russ, My original approach to clearances was very similar to your thinking and the tolerances were only changed at the request of some of the teams to make “sliding the wheels on and off the spindle a bit easier”. I’m not sure that this was really necessary and like you say you then...

Hi Russ, I don’t think that you will be too far away with your tolerances and I would certainly give them a try before changing anything. The basis for my figures was an old and rusty memory and being too lazy to boot up the CAD system! However, I’ve just checked through some of my old...

Hi Russ, Yes, I guess the spindle to wheel tolerancing that I quoted was a little on the loose side but I was more intent on getting across the rationale behind the wheel location and attachment. Neverless the tolerancing does need to be a little on the loose side to account for fitting of...

Hi Guys, If I can add my two cents worth. Ideally there are three functions to consider when attaching a wheel to a hub. Firstly the wheel should centralize accurately on the vehicle hub spindle. This should be achieved by locating the centre bore of the wheel onto the vehicle hub...
